PART 1. SYSTEM OVERVIEW

1.1 SIZE AND CONFIGURATIONThe DCS 50si is a digital ISDN compatible telephone system designed for small busi-nesses. It can operate with the functionality of a square key system, PABX or a combina-tion of both (hybrid). The DCS 50si employes the very latest DSP (Digital Signal Proces-sor) digital technology.

The DCS 50si offers a variety of interface cards that allow connection to the public tele-phone network or to private networks. These are generally referred to as trunk cards. Twotypes of telephones can be connected to the system. Proprietary digital phones called“keysets” connect to digital line interface cards (DLI). Standard telephones generally called“single line sets” connect to single line interface cards (SLI). In addition, DLI station portsare used to connect peripheral devices such as door phones and add-on modules. Mis-cellaneous circuits are provided to allow such optional features as external paging, musicon hold, background music, common audible devices, alarms and emergency power fail-ure telephones.

All DCS keysets utilize a single PCB with surface-mounted components assuring the highestproduct quality and long life. Samsung’s customary large, easy-to-read displays and LEDsin the button design make them much easier to use. In many instances, sophisticatedfeatures are made simple through the use of friendly display prompts or push-on/push-offfeature keys.

Expanding the DCS 50si system is both economical and easy. Begin with the basic KeyService Unit and then add an expansion cabinet as your business grows (See Figure 1–1). The KSU has 8 keyset ports and 3 universal card slots that can be used for stations,trunks or 2x4 combination cards. In addition, the KSU has dedicated slots for a 2SLI cardand a miscellaneous function card. The expansion cabinet adds a further 3 universal slotsand a dedicated slot for a CADENCE CVM8A card. The systems low density card designallows greater flexibility when configuring a system for the right combination of lines andstations. A removable memory card (SMEM2 card) makes it convenient to upgrade tofuture feature packages as well as providing quick and easy servicing. The maximumquantities of the various station and trunk types can be seen in the table 1–1.

CONFIGURATION NOTES1. A maximum of 40 stations can be installed on the system.2. Only one 2 SLI card can be installed in the system.3. Only one SMISC card can be installed in the system.4. Up to six expansion cards can be installed in the system.5. Only one CADENCE card can be installed in the system.6. Installing CADENCE reduces the maximum number of stations to 32.7. Only eight KDbs can be installed in the system and they must be installed on keysets

connected to the (8) eight 2B+D ports on the KSU motherboard.

1.2 TECHNOLOGYSystem switching is accomplished by means of a custom IC “engine” that provides 128switchable digital channels. Each of the 128 digital channels is automatically assigned tocarry voice or data as required by system operation in a PCM format. In addition to the 128channels mentioned above , the system also utilizes Digital Signal Processors or DSPs.Each DSP may be configured by the switching control program as a DTMF receiver or aC.O. tone detector on a per-call basis. The engine chip contains four DSPs and four moreare added when an SMISC card is installed. This means that the system contains a totalof eight DSP channels when fully expanded. The DSP channels are fully shared through-out the system as a common resource.

MEMORYThe system operates using stored program control. This program is stored in four EPROMchips (2048 Kbytes of memory). All specific customer data is stored in non-volatile ran-

dom access memory (NV-RAM) located on the removable SMEM2 card. It is protected bya super capacitor providing seven days of memory protection in the event of loss of ACpower to the system.

MICROPROCESSORSThe DCS 50si uses distributed processing. The system’s primary processor is a 16 bitMotorola® MC68000 operating at a clock speed of 16MHz. The secondary level of pro-cessing is done in the keysets.

1.3 PROGRAMMINGThe DCS 50si comes with default data. This data provides for operation within secondsafter applying power. All trunks and stations are assigned according to the default num-bering plan. This numbering plan is flexible and may be changed if so desired. The tech-nician customizes this default data to meet the end user’s requirements.

The system can be programmed from any display keyset without interrupting normal sys-tem operation. There are three levels of programming: TECHNICAL, CUSTOMER andSTATION. The technician level has access to all programs and can allow the customeraccess to system programs as needed. Technician and customer access are controlledby different security passcodes.

The DCS 50si also allows the use of a proprietary computer program called PCMMC. Thispermits a technician to program the system using a personal computer. PCMMC can beused on-site to modify the customer database or to download (save) the entire customerdatabase to a file. This file can then be saved as a backup and uploaded when required torestore the database.

Through the use of modems, PCMMC can access a DCS 50si system remotely (off-site)to make database changes or perform uploads or downloads of the customer databaseas if the technician were on-site.

4.1 SYSTEM FEATURE DESCRIPTIONSACCOUNT CODE ENTRY

Station users may enter an account code (maximum 12 digits) before hanging upfrom a call. This account code will appear in the SMDR printout for that call record.Keyset users may enter this code using an account (ACCT) key without interrupt-ing a conversation. Single line telephone users must temporarily interrupt the callby hook-flashing and dialing the feature access code. Account codes can be up to12 digits long.

FORCED

When forced, they are always verified from a system list of 500 entries. Accountcodes are always printed on the SMDR report. They can contain digits 0–9.

VOLUNTARY

Users may elect to enter an account code for any call. They can include digits 0–9,star (�) and #.

ALL CALL VOICE PAGEUsers can page all internal and all external paging zones at the same time bydialing the All Page code. Keysets may be restricted from making or receivingpages in system programming. A maximum of 40 keysets can be programmed toreceive page announcements.

ATTENTION TONETo get your attention, a brief tone precedes all page announcements and intercomvoice calls. There are separate programmable duration timers for page and voiceannounce tones.

AUTHORIZATION CODESAuthorization codes are used to give permission to make a call. These four digitauthorization codes can be either forced or voluntary. When used, authorizationcodes will automatically change the dialing station’s class of service to the levelassigned to the authorization code. Authorization codes may be programmed toprint or not print on SMDR.

FORCEDWhen a station is programmed for forced authorization, the user must always enterthis code before dialing is allowed. The dialed authorization code is verified from asystem list of 250 entries.

VOLUNTARYAny station user can always enter an authorization code before they begin dialing.The dialed authorization code is verified from a system list of 250 entries.

4.1.3

AUTO ATTENDANT

The SMISC2 card for the DCS 50si includes four ports of auto attendant for simul-taneous answering and call processing. Sixteen professionally recorded promptsinform callers of the progress of their calls. Several examples are the following: “I’msorry. There is no answer”, “That station is busy” and “Invalid number. Please tryagain”, Two minutes of battery-backed random access memory (RAM) provide upto 48 customer recordings for announcements or greetings. Twelve individual greet-ing boxes, each with its own dialing options, allow you to build call routing branchesas needed. Callers are routed through the branches by dialing extension numbersor single digits.

NOTE: Requires optional hardware and/or software. Ask your dealer for details.

AUTOMATIC HOLDWhile a keyset user is engaged on an outside (C.O.) call, pressing another trunkkey, route key or CALL button automatically places the call on hold when AutomaticHold is enabled. Pressing TRSF, CONFERENCE, PAGE or a DSS key alwaysautomatically places a C.O. call on hold. Intercom calls can be automatically heldonly by pressing TRSF or CONFERENCE. Each keyset user can enable or disableAutomatic Hold.

BACKGROUND MUSICKeyset users may choose to hear music through their keyset speakers when op-tional external sources are installed. Each user may adjust this level by the use ofa volume control program at the selected keyset.

CALLER IDENTIFICATION

CALLER IDCaller ID requires that optional software and hardware be installed in the DCS 50siKSU. In addition, Caller ID service must be provided by your local telephone com-pany. The availability of the calling party name or number depends on the type ofCID service offered by your local telephone company. The Caller ID feature is de-pendent on having an LCD keyset to show the name or number in the top line of thedisplay. NOTE: Requires optional hardware and/or software. Ask your dealer fordetails.

NAME/NUMBER DISPLAY

Each LCD keyset user can decide if he/she wants to see the CID name or CID/ANInumber in the display. Regardless of which one is selected to be seen first, the N/Nkey is pressed to view the other pieces of CID information.

NEXT CALLIn the event that you have a call waiting or a camped-on call at your keyset, you canpress the NEXT key to display the Caller ID information associated with this next

��

call in queue at your station. Either the CID name or CID number will show in thedisplay depending on your N/N selection.

SAVE CIDAt any time during an incoming call that provides CID information, you may pressthe SAVE key. This saves the CID number in the Save Number feature. Pressingthe SAVE number redial key will dial the CID number. The system must be usingLeast Cost Routing (LCR) to dial the saved number.

STORE CIDAt any time during an incoming call that provides CID, you may press the STOREkey. This saves the CID number as a speed dial number in your personal speeddial list. The system must be using LCR to dial the stored number.

INQUIRE PARK/HOLDHaving been informed that an incoming call is on hold or has been parked, you mayview the Caller ID information before you retrieve the call. This will influence howyou choose to handle the call.

CID REVIEW LISTThis feature allows display keyset users to review CID information for calls sent totheir stations. This list can be from ten to fifty calls in a first in, first out basis. The listincludes calls that you answered and calls that rang your station but that you didnot answer. When reviewing this list, you can press one button to dial the personback. The system must be using LCR to dial the stored number.

INVESTIGATEThis feature allows selected stations with a special class of service to investigateany call in progress. If CID information is available for an incoming call, you willknow to whom this station user is speaking. On outgoing calls, you can see whowas called. After investigating, you may barge-in on the conversation, disconnectthe call or hang up.

ABANDON CALL LIST (50)The system has a system-wide abandon call list that stores CID information for thelast 50 calls that rang but were not answered. The list is accessed using the operator’spasscode. When reviewing this list, you are provided options to CLEAR the entry orDIAL the number. You can use the NND key to toggle between the CID name, CIDnumber and the date and time the call came in. The system must be using LCR todial numbers from the abandon call list.

CID ON SMDRThe Station Message Detail Records report can be set to include CID name andCID number for incoming calls. This format expands the printout to 113 characters.Use a wide carriage printer or an 80 column printer set for condensed print.

4.1.4

��

NUMBER TO NAME TRANSLATION (350)

The system provides a translation table for 350 entries. When the CID number isreceived, the table is searched. When a match is found, the system will display thecorresponding name. This will allow users in areas that do not support deluxe CallerID to provide names for regular callers.

CALL FORWARDINGThis feature allows the user to redirect (forward) incoming calls. The calls can beredirected to the attendant, a hunt group, voice mail, external number or anotherstation user. If the destination station is in Do Not Disturb (DND), the calling partywill receive DND/Reorder tone. Calls cannot be forwarded to a door phone.

ALL CALLS

This type of forwarding is not affected by the condition of the station. All calls areimmediately redirected to the designated destination. If desired, the destinationstation may redirect the call back to the forwarded station by using the transferfeature. The forwarded station user can continue to originate calls as usual. If nokey is programmed as Forward All, the TRSF key lights steady when a Forward Allcondition is set.

BUSY

This feature forwards all calls only when the station set is busy. The station usercan originate calls as usual.

FORWARD DND

This feature works with the Do Not Disturb feature. This allows calls directed to astation in Do Not Disturb or One Time Do Not Disturb to forward immediately toanother destination.

NO ANSWER

This feature forwards calls that are not answered within a preprogrammed time.The user can originate calls as usual and receive calls if present. The timer isprogrammable on a per-station basis to allow for differences in individual workhabits.

BUSY/NO ANSWER

This feature allows the station user to use both types of forwarding simultaneously,provided the destinations have already been entered in the usual manner.

FOLLOW ME

This feature allows the user to forward all calls from another station to the user’sstation or change the forward destination to the user’s current location.

4.1.5

��

EXTERNALThis feature forwards C.O. calls to an external number via a central office trunk ifallowed by class of service. These C.O. calls forward only after the programmableexternal call forward delay timer expires.

TO VOICE MAILEach station may be programmed to allow or deny the ability to forward intercomcalls to voice mail. When denied, valuable message time in the voice mail systemcan be saved.

CALL HOLD (EXCLUSIVE)Outside calls can be placed on exclusive hold at any keyset by pressing HOLD twiceduring a call. Calls placed on exclusive hold can only be retrieved at the keyset thatplaced the call on hold. Intercom calls are always placed on exclusive hold.

CALL HOLD (SYSTEM)Outside calls can be placed on system hold at any station. Users may dial theaccess code or press the HOLD button. Calls on system hold may be retrieved atany station.

CALL HOLD (REMOTE)Outside calls can be placed on hold at a remote station. This feature allows calls tobe answered at one keyset and placed on hold at another station. This allows timefor the user to proceed to that station or allows the party that the call was intendedfor to have that call placed at their station. The call or trunk button will flash at theremote hold station.

CALL PARK AND PAGEEach C.O. line has its own park zone. This simple method eliminates confusionand ensures that a park zone is always available. Pressing the PAGE key parks thecall automatically. There are no extra buttons to press and there is no lost timelooking for a free zone.

CALL PICKUP

DIRECTEDWith directed call pickup, users can answer calls ringing at any station by dialing acode plus that station’s extension number or by pressing the feature button andthen dialing the extension.

GROUPS (20)In addition, calls can be picked up from a station group in a similar manner. Thegroup pickup feature allows users to answer any call ringing within any pickupgroup. There are 20 pickup groups available. A station cannot be in more than onepickup group. To use this feature, station users either dial the access code or pressthe assigned feature button followed by the pickup group number.

4.1.6

��

4.1.7

CALL WAITING/CAMP-ONBusy stations are notified that a call is waiting (camped-on) when they receive atone. The tone is repeated at a programmable interval. Keysets receive an off-hookring signal through the speaker and single line stations receive a tone in the hand-set. The volume of the camp-on tone can be set by the station user. Camped-oncalls follow Forward No Answer if a Forward No Answer destination has been set.

CENTREX/PBX USECENTREX and PBX lines can be installed in lieu of central office trunks. CENTREXand PBX feature access codes including the command for hook-flash (FLASH) canbe stored under one touch buttons. Toll restriction programming can ignore PBX orCENTREX access codes so that toll calls can be controlled when using these ser-vices.

CHAIN DIALINGKeyset users may manually dial additional digits following a speed dial call or chaintogether as many speed dial numbers as are required.

CLASS OF SERVICEThe system allows a maximum of 30 station classes of service. Each class ofservice can be customized in memory to allow or deny access to features and todefine a station’s dialing class. Each station can be assigned different classes ofservice for day and night operation.

COMMON BELL CONTROLEach MISC card is equipped with three programmable relays. A relay program-mable relays. A relay programmed as a common bell provides a dry contact pair tocontrol a customer-provided bell or common audible device. These contacts mustbe programmed as members of a station group and may provide steady or inter-rupted closure.

CONFERENCEThe system allows six simultaneous conferences.

ADD-ON (5 PARTY)Any combination of up to five parties (stations or outside lines) can be joined to-gether in an add-on conference. Parties may be eliminated or added after a confer-ence has been established.

UNSUPERVISEDA station user may set up a conference with two or more outside lines and then exitthe conference leaving the outside lines connected in an unsupervised (trunk totrunk) conference.

COMPUTER TELEPHONY INTEGRATION (CTI)Computer Telephony Integration (CTI) allows integration between the DCS 50siand a personal computer system (PC) or a local area network (LAN). Caller IDservice is required on TAPI and TSAPI inbound call applications that use the CIDinformation to display computer records in conjunction with the presentation of thecall to the station on the DCS 50si system. TAPI and TSAPI are described below.

TAPIJointly developed by Intel and Microsoft, TAPI (Telephony Applications Program-ming Interface) delivers telephony features to the Windows desktop. TAPI is anopen application interface (OAI) protocol that supports First Party Call Control. ADCS Computer Telephony Module (CTM) is required to connect any keyset to apersonal computer running Windows 3.1 or Windows 95. The number of CTMsthat can be installed on a system is only limited by the number of keyset ports. Thefeatures and functionality of the keysets are not changed.

TSAPITelephony Services Application Programming Interface (TSAPI) was developed byNovell and AT&T and is the method of integrating the DCS 50si system to a com-puter. TSAPI is a LAN based solution allowing computers to communicate directlyto the telephone system over the network system. This establishes a logical con-nection rather than a physical connection between telephone and computer. It elimi-nates the cost and administrative overhead of connecting every PC to a desktopphone. It emphasizes third-party call control. (Example: calls can be tracked asthey are transferred, making it more suited to large office applications). TSAPI canemulate first-party type call control for the DCS 50si, rather than from the tele-phone as TAPI does. For example, to make a call, the DCS 50si, rather than thetelephone would dial the phone number, and the call would then be transferred tothe telephone. Novell Telephony Services 2.1 or higher specifies the data commu-nications link between the Novell Netware file server running the Netware Tele-phony Services NLM and the Samsung DCS 50si. The physical connection fromthe Novell Telephony server to the DCS 50si is an EIA-232 connection an I/O porton the SMISC card.

CTI SYSTEM LINKThe DCS 50si has a system wide CTI link. This CTI link is provided from one of theserial I/O ports on the SMISC and can be used with either the DCS TSAPI driver toconnect the system to a Novell LAN or the TAPI 2.0 driver to provide a CTI link to aWindows NT server based LAN environment.

CUSTOMER SET RELOCATIONCustomer Set Relocation allows the customer to exchange or swap similar stationsin the DCS 50si without wiring changes. All individual station assignments such astrunk ring, station group, station COS, station speed dial, button appearances, callforwarding, etc. will follow the Customer Set Relocation program.

��

4.1.9

DATA SECURITYSingle line extensions used with modems and facsimile machines can be pro-grammed so that they will not receive any system-generated tones that would dis-rupt data transmissions. In addition, these devices receive DCS C.O. ringing pat-tern instead of intercom ring pattern. Devices connected to an SLI card receive adisconnect signal upon termination.

DATABASE PRINTOUTA copy of the customer database can be obtained by using PCMMC. This informa-tion can be directed to a printer or the PC screen and may be done either on-site orremotely. A complete database or specific data blocks may be obtained.

DIALED NUMBER IDENTIFICATION SERVICE (DNIS)When DNIS service is provided on an incoming E&M trunk the DCS 50si can routecalls based on the numbers received.

DIRECT IN LINESOutside lines may be programmed to bypass the operator(s) and ring directly atany station or group of stations.

DIRECT INWARD DIALING (DID-USE E&M TRUNK)The DCS 50si can use local telephone company-provided DID service via an E&Mtrunk. When programmed, anyone dialing a user’s personal number rings directlyto that user’s office. DID calls to a busy station have the option to return busy signalto the C.O. or return ringback to the C.O. When ringback is selected, the calledstation receives off-hook ring. Multiple DID numbers can ring the same extensionor station group and display keysets show a DID directory name when ringing if aname has been programmed. DID calls can be assigned both a day and night ringdestination. This allows routing of DID calls that have one destination during thesystem Day mode to be routed to a different destination during the system Nightmode. DID calls that are directed to ring a voice mail machine can be identified bya special digit (see Voice Mail Integration). As it is possible to program E&M trunksto follow the DID translation tables, the system can use both way DID type service.

DIRECT INWARD SYSTEM ACCESS (DISA)Users can call in on specific DISA lines at any time, input a security code andreceive system dial tone. Users can now place internal calls or if permitted, callsusing C.O. lines. The caller must have a tone dial phone and know his/her DISAsecurity code. DISA lines can be used as both way lines or incoming only and maybe active in day mode, night mode or both. The C.O. lines used for DISA must havedisconnect supervision.

DIRECT TRUNK SELECTIONEach station can be allowed access to or denied access from a trunk or trunk groupby access code when LCR is activated. When restricted, the station user must usea trunk key or a route key.

Notes

��

4.1.10

DIRECTORY NAMESEach station, station group and C.O. line may be assigned a directory name (maxi-mum 11 characters). In addition, each personal speed dial number, system speeddial number and entry in the DID translation table may be assigned a name (maxi-mum 11 characters). These names are displayed during calls with these ports andin the case of station and speed dial names, can be used to originate calls. See theDial by Name feature (Station Features).

DISA SECURITYTelephone fraud and long distance theft continue to increase; therefore, we haveintroduced a DISA security system. If an incorrect DISA passcode is entered re-peatedly (as is the case with “hackers”), the DISA system can be automaticallydisabled temporarily. Both the number of incorrect passcode attempts and the timethat DISA is disabled are programmable. In addition, all failed attempts to accessDISA print on SMDR (if provided) with a “DE” DISA error flag.

DISTINCTIVE RINGINGA user knows the type of call received by the type of ring heard. Outside calls havea single ring repeated while internal calls have a double ring repeated.

DOOR LOCK RELEASE (PROGRAMMABLE)After answering a call from the door phone, users can dial a code to activate a contactclosure. This can be used to operate a customer-provided electric door lock releasemechanism. The contact closure timer is programmable from 100–2500 ms.

DOOR PHONESThe door phone interface module (DPIM) provides for connection of a door phoneto a DLI port. Pressing the button on the door phone produces a distinctive ring(three short rings repeated) at the assigned station or station group. If not an-swered within a programmable time, the system releases the door phone and stopsthe ringing. Stations may call the door phone directly and monitor the surroundingareas.

DOOR PHONE NIGHT RINGThe ring destination of door phone calls may be different at night than during theday. For example, large factories may want these calls directed to a security deskafter hours.

E & M TIE LINESYour office can be connected to another office with a tie line. Use it to make calls tostations in the other system. If programming allows, you can access lines in theother system to make outside calls. Tie line calls can be put on hold, transferredand conferenced in the same way as are other outside calls. Users accessing thetie line from the other system can get a line in your system and make outgoingcalls. These calls can be controlled by assigning a dialing class to the tie line. Your

��

4.1.11

local telephone company may use E&M tie lines to provide DID service. In thiscase these tie lines can be programmed to follow the DID translation table. SeeDID. Translated E & M tie line calls have Day and Night routing capabilities.

EXECUTIVE BARGE-IN (OVERRIDE)The feature allows specially programmed stations with a barge-in key to overridethe automatic privacy of another station or outside trunk. Programming allows barge-in with or without a warning tone. Stations may also be programmed as “secure” sothat they cannot be barged-in on.

WITH WARNING TONEWhen the barge-in with tone option is set, the barging-in keyset has its microphoneon and the barged-in on station receives an override display. A double burst ofwarning tone sounds and repeats every ten seconds. This feature does not workfrom single line sets.

WITHOUT WARNING TONEWhen the barge-in without tone option is set, the barging-in keyset has its micro-phone muted and the barged-in on station does not receive an override display.This feature does not work from single line sets.

WARNING: BARGE-IN WITHOUT TONE MAY VIOLATE STATE OR FEDERALLAWS CONCERNING THE RIGHT TO PRIVACY. SAMSUNG TELECOMMUNI-CATIONS AMERICA IS IN NO WAY RESPONSIBLE FOR THE POSSIBLE MIS-USE OF THIS FEATURE.

EXECUTIVE/SECRETARY POOLINGEach keyset may be defined as a BOSS or a SECRETARY in system program-ming. Each BOSS can have up to four SECRETARIES and each SECRETARYcan have up to four BOSSES. These arrangements are known as executive/secre-tary pools. There can be multiple pools in a system. When a BOSS is in DND, allcalls to the BOSS ring the first SECRETARY assigned to that BOSS; if that SEC-RETARY is busy, the call hunt to the next available SECRETARY assigned to thatBOSS. If the SECRETARY must communicate with the BOSS while he/she is inDND, pressing the corresponding BOSS button on the SECRETARY’s keyset re-sults in an Auto Answer intercom call being made to the BOSS (providing the BOSSis free). A station can only be the BOSS of one SECRETARY pool. In addition, astation cannot be in more than one pool.

EXTERNAL MUSIC INTERFACESThe system provides an interface for connecting a customer-provided external musicsource and the addition of an SMISC card provides a second interface. Theseinterfaces can be used for background music, station music on hold or trunk musicon hold.

��

4.1.12

EXTERNAL PAGE INTERFACEThe system KSU provides one external page audio output. The addition of an SMISCcard will provide a second audio output and three general purpose relays that maybe assigned to control paging zones. Multiple relays may be assigned to a pagezone.

FLASH KEY OPERATIONWhile a user is on an outside line, pressing the FLASH key will flash the central officeor PBX. This is used for custom calling features on C.O. lines or in conjunction withCENTREX/PBX operation. System programming allows individual flash times for C.O.and PBX lines. When C.O. or PBX flash is not required, setting the timers for twoseconds releases the existing call and returns dial tone to make a new call.

FLEXIBLE NUMBERINGSystem programming allows stations to have two, three or four digit extension num-bers beginning with the digit 2 or 3. Default extension numbers begin with 201.Station hunt group access codes can be two or three digits beginning with the digit5. These can be changed but it will affect other feature access codes. All userguides are written using the default numbering plan.

FLEXIBLE RINGINGEach C.O. line can be programmed to ring at any station or station group. Each linecan be assigned a day ring destination and a night ring destination.

HOT LINEStations can be programmed to call a pre-defined station or station group when-ever that station goes off-hook. A hot line delay timer of 1–250 seconds can beprogrammed to allow sufficient time to make a different call.

IN GROUP/OUT OF GROUPIndividuals assigned to a station hunt group may temporarily remove their tele-phones from the group by pressing the In/Out of Group button providing that thereis someone still in the group. Stations out of a group will not receive calls to thatgroup but will continue to receive calls to their individual extension numbers. Whendesired, the user may put him/herself back into the group by pressing the buttonagain. Users who do not have this button may dial the access code and the groupdesired. A station user is allowed to be in several groups, providing a key and theextender of that group are assigned for each group on the user’s phone.

INCOMING CALL DISTRIBUTIONIncoming calls can be assigned to ring a distributed station hunt group. This allowsall members of the group to share the call load.

��

4.1.13

INCOMING/OUTGOING SERVICEOutside lines are available for incoming or outgoing service. Programming allowsany outside line to be used for incoming calls only, outgoing calls only or both wayservice.

INDIVIDUAL LINE CONTROLEach station in the system can be individually programmed to allow or deny dialingout as well as allow or deny answering for each outside line.

INTEGRATED SERVICES DIGITAL NETWORK (ISDN) INTERFACEThe DCS 50si supports ISDN Basic Rate Interface (BRI) in both station and trunkformats. The S4BRI card for the DCS 50si consists of four circuits each of whichcan support two channels for a total of eight channels per card. The DCS 50si cansupport a maximum of 6 BRI cards giving a total of twenty-four circuits or 48 chan-nels.

An SPLL daughter board must be installed in the system to provide clocking for theBRI cards.

TRUNK INTERFACE

When configured as a trunk a BRI circuit will support the following protocols:

� National ISDN 2� AT&T 5ESS Custom� Nortel DMS 100 Custom

INTEGRATED VOICE MAILThe DCS 50si has a dedicated slot in the expansion cabinet to contain a CADENCE(VM8A) card. This card can be used with both four ports and eight ports (one or twoVoice Processing Modules installed). This will allow such features as Call Record,Answering Machine Emulation and Soft Key mailbox administration. NOTE: Install-ing the CADENCE board reduces the maximum number of stations on the systemto 32.

LEAST COST ROUTINGLeast Cost Routing (LCR) is the ability to automatically select the most cost effec-tive central office route for the outside number dialed by any station. The DCS 50siLCR program includes the following features:

� Option to use or not use LCR or a tenant basis� Programmable LCR access code� Digit analysis table 1000 entries each with ten digits� Routing by time of day and day of week (4 time bands per day)� Routing according to individual station class� Modify digits table 100 entries� Flexible trunk group advance timer� Option to use or not use trunk group advance warning tones

4.1.14

LIVE SYSTEM PROGRAMMINGThe system can be programmed from any display keyset or personal computerwithout interrupting normal system operation. There are three levels of program-ming: technician, customer and station. The technician level has access to all pro-grams and can allow the customer access to system programs as needed. Techni-cian and customer access are controlled by different security passcodes. Program-ming from a PC requires the PCMMC program.

MEET ME PAGE AND ANSWERAfter a user makes a Meet Me Page, the user may remain off-hook to allow thepaged party to meet the user for a private conversation.

MEMORY PROTECTIONIn the event that power is lost to the system, all customer data contained in memoryis retained by the use of a “super capacitor” for approximately seven days. In addi-tion, the PCMMC computer program may be used to produce a backup copy of thecustomer data.

MESSAGE WAITING INDICATIONSWhen calling a station and receiving a busy signal or the no answer condition, thecaller can leave an indication that a message is waiting. The message button willflash red at the messaged keyset. A single line phone will receive a distinctivemessage waiting dial tone. Five message waiting indications can be left at anystation.

MICROPHONE ON/OFF PER STATIONThe microphone can be disabled at any keyset. When the microphone is disabled,the keyset cannot use the speakerphone, although on-hook dialing and group lis-tening are still possible.

MUSIC ON HOLD—FLEXIBLEWhen external music sources are connected, each C.O. line may be programmedto receive one of the two external sources, internally-generated tones or no musicwhen it is placed on hold. If there are no sources installed, each line may receiveeither a 50 ms tone or no music. The system-generated tone is a beep every 3.5seconds.

NIGHT SERVICEThe DCS 50si provides separate ringing locations for all trunks in both the day andthe night modes.

AUTOMATICAutomatic night service allows each tenant to automatically go in and out of nightservice according to the system clock. There are separate time options availablefor each day of the week. This feature can be overridden by a manual night servicekey and passcode.

��

4.1.15

MANUAL

The operator presses the NIGHT key and then dials a passcode to change daymode to night mode operation.

OFF PREMISES EXTENSIONS (OPX)A single line (tip and ring) extension from an SLI card may be connected to tele-phone company-provided OPX circuits to remote locations. 8SLI cards and KDb-SLIs do not support off premises extensions.

OPERATOR GROUPThe operator group can contain 32 stations to answer incoming calls. Calls to thisgroup can be set for distributed, sequential or unconditional ringing. Operators canuse the In/Out of Group feature to meet flexible operator requirements.

OVERFLOW

OPERATOR

When calls ringing a operator group go unanswered, they can overflow to anotherdestination after a programmed period of time. The operator group has its owntimer. The overflow destination can be a station or station group.

STATION GROUP

When calls ringing a station group go unanswered, they can overflow to anotherdestination after a programmed period of time. Each station group has its owntimer. The overflow destination can be a station or station group.

PAGINGSystem software allows the use of four internal and four external paging zones.Stations can page any individual zone, all internal zones, all external zones or allzones simultaneously. Using system programming, each station may be allowed ordenied the abilities to make and/or receive page announcements to any zone orcombination of zones.

POWER FAILURE TRANSFEREach S3TRK card is equipped with two power fail relays. If power fails, these relayscan be used to reroute the first two C.O. lines on the card to single line telephones.When power is restored to the system, the lines and stations return to normaloperation and calls in progress will be disconnected.

PRIME LINE SELECTIONAny station can be programmed to select a specific line, line group, telephonenumber, station or station group.

PRIVATE LINESFor private line use, stations can be prevented from dialing and/or answering any line.

��

4.1.16

PROGRAMMABLE LINE PRIVACYEach outside line can be programmed to ignore the automatic line privacy. Thisallows up to four other parties to join your conversation by simply pressing the linebutton. This is similar to 1A2 key telephone operation.

PROGRAMMABLE TIMERSThere are over 50 programmable system timers to allow each installation to becustomized to best fit the end user’s application.

RECALLSCalls put on hold, transferred or camped-on to any station will recall to the originat-ing station if not answered within a programmable time. A recall that goes unan-swered for the duration of the attendant recall timer will recall to the system opera-tor group. Hold, transfer, camp-on and attendant recalls have individual program-mable timers. Calls recalling to buttons with tri-colored LEDs will flash amber.

REMOTE PROGRAMMING—PCRemote programming allows the technician to access the system database from aremote location for the purpose of making changes to the customer data. Cus-tomer-provided modems and a PC using an optional software package will be neededto implement this feature.

RING OVER PAGEAny outside line can be programmed to ring over a customer-provided paging sys-tem. Outside lines, door phones and station groups may ring over page in the dayor night mode.

SINGLE LINE CONNECTIONSSingle line ports allow connection of a variety of single line telephones plus fac-simile machines, answering machines, loud bells, computer modems, cordlessphones and credit card machines. When connecting customer-provided equipmentto these extensions, compatibility should be checked out before purchase to en-sure correct operation. Central office ring cadence can be selected for SLT sta-tions. This is helpful when optional devices cannot detect DCS intercom ring ca-dence.

SPEED DIAL NUMBERS (1500)A library of 1500 speed dial numbers may be allocated as needed. The system listcan have up to 500 numbers and each station can have up to 50 numbers. Speeddial numbers are assigned in blocks of ten. Each speed dial number may containup to 18 digits.

SPEED DIAL BY DIRECTORYThe DCS 50si system provides the user with the ability to look up a speed dialnumber and place the call. There are three speed dial selections: personal, system

��

4.1.17

and station. This feature can be used with the soft keys on the display keysets or asa programmable button.

STATION HUNT GROUPS (30)System programming allows up to 30 station hunt groups. One of three ring pat-terns—sequential, distributed and unconditional—is available for each group. Eachunconditional group may contain a maximum of 32 stations. A station may be as-signed to more than one group. The default directory numbers to call these groupsare 501–529. Group 500 is reserved for the operator group and is called by dialing“0.” Each station group has its own recall timer for calls transferred to that group.

STATION MESSAGE DETAIL RECORDING (SMDR)The system provides, via an optional SIM, records of calls made, received andtransferred. Connecting a customer-provided printer or call accounting system willallow collection of these records. Each call record provides the following details:station number, outside line number, start date, start time, duration of call, digitsdialed (maximum 18) and an account code if entered. The system may print aheader followed by 50 call records per page or send continuous records with noheader for use with a call accounting machine. See the sample printouts.

The SMDR format contains many options that allow it to be customized for acompany’s individual needs. Options to print include incoming calls, outgoing calls,in and out of group status, change in DND status and authorization codes.

SYSTEM ALARMSThe basic KSU has an alarm sensor pair, when this pair is short-circuited, thesystem will ring a preprogrammed destination with a customized display message.The alarm destination can be a station or station group.

A DISA alarm will warn the customer if the DISA security system has been trig-gered by too many incorrect password attempts. The alarm can ring any station orgroup of stations and show an appropriate display at the assigned stations.

SYSTEM DIRECTORYEach station, station group and outside line can have an 11 character directoryname. This name will appear on keyset displays to provide additional informationabout lines and stations.

TENANT SERVICE (2)There are several programs that allow the DCS 50si to be installed in tenant appli-cations. These features allow a technician to split the system in two with eachtenant having individual control over operator groups, page zones, speed dial num-bers, night service (manual or automatic), DISA and customer level programming.Each tenant is separate. No intercom calling between tenants is permitted.

Notes

4.1.18

TOLL RESTRICTIONThere are 250 allow and 250 deny entries of 11 digits each. Each of these entriescan apply to dialing classes B, C, D , E, F and G. Expensive 976, 1-900, 411 andoperator-assisted calls, as well as specific area and office codes, can be allowed ordenied on a per-class basis. Class A stations have no dialing restrictions and ClassH stations cannot make outside calls.

Any outside line may be programmed to follow station toll restriction or follow thetoll restriction class assigned to it. Each station and trunk can have a day dialingclass and a night dialing class.

SPECIAL CODE TABLEA Special Code Table of ten entries (four digits each) allows use of telephonecompany features such as CID blocking (*67) or call waiting disable (*70) withoutinterference to toll restriction or LCR. The Special Code table allows use of thesecustom calling features on a per call basis.

TOLL RESTRICTION OVERRIDEProgram options allow system speed dial numbers to follow or bypass a station’stoll restriction class. In addition, users may make calls from a toll restricted stationby using the walking class of service or authorization code feature.

TONE OR PULSE DIALINGOutside lines can be programmed for either tone or pulse dialing to meet localtelephone company requirements.

TRANSFERSystem operation permits station users to transfer calls to other stations in thesystem. Transfers can be screened, unscreened or camped-on to a busy station.

TRUNK GROUPS (11)Outside lines can be grouped for easy access by dialing a code or pressing abutton. There are 11 trunk groups available. Access codes are 9 and 80–89.

UNIFORM CALL DISTRIBUTION (UCD)UCD is used whenever the user expects to have more ringing calls than people toanswer them. It prevents callers from receiving busy signals or lengthy delays be-fore answering. Callers reaching a busy station group are held in queue for anavailable agent. First and second announcements reassure the caller until an agentbecomes free. Up to five separate UCD groups can be created. Programmableautomatic logout removes a station from the group if a call is placed to an unat-tended station, thus preventing unanswered calls. A wrap-up timer prevents callsto a station for a programmable period of time to allow the agent to finish up workassociated with the call.

NOTE: Requires optional hardware and/or software. Ask your dealer for details.

��

4.1.19

MAXIMUM OF FIVE GROUPSThe UCD group option allows callers in queue at a UCD group to be temporarilydiverted to an announcement device and then placed back in the queue. A wrap-uptimer will allow agents to complete paperwork before receiving the next UCD call.

CALL STATISTICSUCD supervisor positions using a display keyset can monitor the number of calls inqueue, the time that the oldest caller has been waiting, the total number of callsreceived for the current day and the average time a caller waits to be answered.

AGENT STATISTICS

UCD supervisor positions using a display keyset can monitor the number of agentsin a group and how many agents are currently logged in. Each station’s status canbe reviewed for the number of calls answered and the average call length of thecurrent day.

GROUP SUPERVISORSMultiple supervisors can be assigned to each group or one station can be givensupervisor status for multiple groups. The group supervisor (using a display keyset)can add and delete agents in real time from the group to handle the workload.

PRINTED REPORTSAgent supervisors may run printed reports to a customer-provided printer, showingthe data available on the supervisor displays.

UNIVERSAL ANSWERStation users may dial the Universal Answer code or press the UA key to answerany outside lines programmed to ring the UA device. The UA device can be astation, group of stations, common bell or ring over page.

VOICE MAIL INTEGRATIONThe DCS 50si system uses DTMF tones (inband signaling) to communicate withany compatible voice mail system. Stations can call forward to a voice mail system.When answered, the system will send DTMF tones routing the caller directly to thecalled station user’s mailbox. Keyset users can press one button to retrieve mes-sages from the voice mail system. A Voice Mail Transfer key permits keyset usersto easily transfer a caller directly to an individual voicemail box without navigatingthrough menus.

NOTE: Although most voice mail systems will work with the DCS 50si, the systemdata has default values set to work with the Starmail Voice Processing System.They may need to be changed if you are using another system.

4.1.20

WALKING CLASS OF SERVICEThis feature allows users to make calls or use features from a station that is re-stricted. The users may either use the WCOS feature code or the authorizationcode feature. Both methods change the class of service to correspond with thestation passcode or authorization code that is dialed. After the call is completed,the station returns to its programmed class of service.

APPOINTMENT REMINDERKeysets with an alarm key can be used like an alarm clock. When programmed fora specific time, the keyset will sound a distinctive ring to remind the user of meet-ings or appointments. Alarms can be set for “today only” or for every day at thesame time. Up to three alarms may be set at each keyset. Display keysets can alsoshow a programmed message when the alarm rings.

��

4.2.2

AUTOMATIC HOLDStation users can enable or disable automatic hold at their keysets. While a user isengaged on an outside (C.O.) call, pressing another trunk key, route key or CALLbutton automatically puts the call on hold when this feature is enabled. PressingTRSF, CONFERENCE, PAGE or a DSS key will always automatically place the callon hold. This type of automatic hold is not a user-selectable option.

AUTOMATIC PRIVACYAll conversations on outside lines and intercom calls are automatically private. Theprivacy feature can be turned off on a per-line basis.

BACKGROUND MUSICWhen customer-provided music sources are connected, each keyset user maylisten to background music. The HOLD button turns BGM on or off and the volumeis controlled by the volume control keys. Once source is located in the KSU. Asecond source is located on the optional SMISC card.

BUSY STATION CALLBACKWhen reaching a busy station, callers may request a callback by pressing onebutton or dialing a code. The system rings the caller back when that station be-comes idle (a system-wide maximum of 100 callbacks are allowed at one timeincluding busy station and busy trunk).

BUSY STATION INDICATIONS (BLF)DSS/BLF keys may be assigned to any keyset or add-on module. These buttonswill be off when the station is idle, light red when that station is in use and flashdistinctively when that station is in the DND mode.

CALL FORWARDINGStation users can forward internal and outside calls to other destinations immedi-ately (Forward All), when busy (Forward Busy) or if not answered in a program-mable number of seconds (Forward No Answer). These forward destinations canall be different. Once a destination has been programmed, it can be turned on andoff with a programmable key. Forward All takes priority over Busy and No Answerconditions.

In addition to the three usual methods of forwarding described above, a fourthoption called Follow Me is available. This option allows a station user to set aForward All condition from his/her station to another station while at the remotestation. To display the Follow Me condition, the TRSF key lights steady red at thestation that is forwarded. The TRSF key also lights if Forward All is set and no keyis programmed for Forward All.

Keyset users can be given an external call forward button to forward their calls toan external phone number. Each outside line may be programmed to either follow

��

4.2.3

or ignore station call forwarding. A per-station option controls whether internal callsforward to voice mail or not. Single line telephones must have the system adminis-trator program this feature for them.

CALL PICKUPWith directed call pickup, a user can answer calls ringing at any station by dialing acode plus that extension number. The group pickup feature allows the user to an-swer any call ringing within a pickup group. Pickup keys may be customized withextenders to allow pickup from a specific station or pickup group. The DCS 50sihas 20 programmable pickup groups.

DIAL BY NAMEEach system and personal speed dial number can have an associated directoryname. A speed dial number can be selected by scrolling alphabetically through thedirectory name list. This on-line “directory” allows the user to look up and dial num-bers in seconds.

DIRECT STATION SELECTION (DSS)Programmable keys can be assigned as DSS keys and associated with extensionnumbers. Users press these keys to call or transfer calls to the assigned stations.

DO NOT DISTURB (PROGRAMMABLE)The Do Not Disturb (DND) feature is used to stop all calls to a station. Systemprogramming can allow or deny use of the DND feature for each station. Partiescalling a station in DND will receive reorder tone. When in DND mode, calls may beforwarded to another destination. See Forward DND option. A keyset without aDND button can activate DND via the feature access code. The ANS/RLS key willflash at 112 ipm (rapidly) when DND is set. There is a programmable option to allowa C.O. line to override DND at its ring destination if that destination is a singlestation.

DOOR LOCK RELEASEStations programmed to receive calls from a door phone can dial a code to activatea contact closure for control of a customer-provided electronic door lock.

EXCLUSIVE HOLDPressing HOLD twice will hold a call exclusively at a station so no other station canpick up that call. Intercom calls are automatically placed on exclusive hold.

GROUP LISTENINGThis feature allows users to turn on the speaker while using the handset. It allowsa group of people to listen to the distant party over the speaker without the micro-phone turned on.

HEADSET OPERATIONEvery keyset can be programmed to allow the use of a headset. In the headsetmode, the hookswitch is disabled and the ANS/RLS key is used to answer and

release calls. Keyset users may turn headset operation ON/OFF by keyset pro-gramming or more easily by pressing the headset ON/OFF key. The headset keylights steady red when the keyset is in headset mode. The ANS/RLS key lights ifheadset mode is activated by keyset programming only.

HEARING AID COMPATIBLEAll DCS keysets are hearing aid compatible as required by Part 68 of the FCCrequirements.

LINE QUEUING WITH CALLBACKWhen the desired outside line is busy, the user can press the CALLBACK key ordial the access code to place his/her station in a queue. The user will be calledback when the line is available (a maximum of 100 callbacks are allowed system-wide at one time including busy station and busy trunk).

LINE SKIPPINGWhen the user is talking on an outside line and the automatic hold feature is turnedoff, he/she may press an idle line key and skip to that line without causing theprevious call to go on hold.

MESSAGE WAITING LIGHT/INDICATIONWhen a message indication is left at a keyset, the MESSAGE button will slowlyflash red. Single line telephones will receive a distinctive dial tone to notify themthat a message is waiting. Message waiting indications can be left for any station orgroup of stations.

MUTE MICROPHONE/HANDSETAny keyset user can mute the keyset’s handset transmitter by pressing the MUTEkey. In addition, keyset users can also mute the keyset microphone while the keysetis in speakerphone mode.

OFF-HOOK RINGINGWhen a keyset is in use, the system will provide an off-hook ring signal to indicatethat another call is waiting. The ring signal is a single ring repeated. The interval iscontrolled by a system-wide timer. Single line stations will receive a tone burstthrough the handset receiver instead of a ring.

OFF-HOOK VOICE ANNOUNCE (STANDARD)Keysets may receive a voice announcement while on another call. The calling sta-tion must have an OHVA key. When transferring a call to a busy keyset or whilelistening to busy signal, the station user can press the OHVA key to make an OHVAcall to the busy keyset. If the called keyset is in the DND mode, it cannot receiveOHVA calls.

OFF-HOOK VOICE ANNOUNCE (EXECUTIVE)A keyset associated with an add-on module (AOM) may receive an executive off-hook voice announcement while on another call. The called keyset user may replyhandsfree without interrupting the call in progress. Only keysets with an off-hookvoice announce button (OHVA) can off-hook voice announce to keysets with AOMs.

ONE TIME DO NOT DISTURBThe Do Not Disturb (One Time) feature is used to stop all calls to a station when theuser is on an outside line and does not want to be disturbed for the duration of thecall. Upon completion of the call, DND is canceled and the station is returned tonormal service. This feature requires a programmed button.

ONE TOUCH DIALING KEYSFrequently used speed numbers can be assigned to one touch dialing keys for fastaccurate dialing.

ON-HOOK DIALINGAny keyset user can originate calls without lifting the handset. When the called partyanswers, the user may speak into the microphone or lift the handset for more privacy.

PROGRAMMABLE KEYSLCD 24B and STD 24B keysets have 24 programmable keys and LCD 12B andBasic 12B keysets have 12. Each key can be programmed for more than 25 differ-ent uses to personalize each phone. Examples of keys include individual outsideline, individual station, group of lines, group of stations and one touch speed dialbuttons. Using these keys eliminates dialing access codes.

The following feature keys have extenders that make them more specific: SPEEDDIAL, SUPERVISOR, PAGE, DSS, DIRECTED PICKUP, GROUP PICKUP, DOORPHONE, BOSS, PROGRAMMED MESSAGE, IN AND OUT OF GROUP, FOR-WARD and VOICE MAIL TRANSFER. The extender can be a station, a group oranother identifying number.

PROGRAMMED STATION MESSAGESAny station may select one of twenty messages to be displayed at a calling party’skeyset. Ten messages are factory-programmed and the remaining ten can be cus-tomized by the system administrator (16 characters maximum).

NOTE: The calling party must have a display keyset to view these messages.

4.7 CALL STATISTICSCALLS IN QUEUE NOW

How many calls are currently in queue.

This statistic is a real time statistic and so will not print on a report.

ABANDONED CALLS

This shows the number of callers that reached the UCD group, but hung up beforebeing answered. A high number probably means that there are not enough agentsavailable and the wait time is too long.

AVERAGE RING TIMEThis is calculated from the time an agent begins to ring until the time an agentanswers the call, this does not include ringing at an agent station that does notanswer or is logged out because of the ring next option.

NUMBER OF TIMES ALL AGENTS BUSYThis is the number of times that a call is placed to an UCD group and all agents arebusy or out of group. This check is made when the call is first placed to the group.

Example: If there are 5 members in a group, 3 are Out of Group one is busy andone is idle, and a call is placed to the group, because there is an idle station the allagents busy counter is not incremented.

If the idle station rings, does not answer and is logged out, although the condition ofthe group is now all agents busy, the check has been made and the agent busystatistic does not increment.

Also if a call comes into a group with all agents busy and then one becomes idle,the busy counter will increment because the check has been made.

AVERAGE TIME IN QUEUEThis is calculated as an average of all the calls that were in queue.

Note that this is ONLY an average of the calls that were in queue. The caller musthave overflowed to the UCD recording to be considered in queue.

A call is considered in queue until it is answered or until it goes to the final destina-tion.

TOTAL CALLS RECEIVEDThe total number of times that calls were sent to a group. This includes calls thatwere answered by the group, calls that went to a group with all agents busy or outof group, calls that are abandoned and calls that go to UCD final destination. Thisincludes intercom calls to the UCD group.

4.7.1

��

If this number is less than the total calls received by all the agents it is possible thatcalls were transferred from one agent to another.

If this number is more than the total calls received by all the agents it is possiblethat calls were unanswered by an agent and went to final destination or callershung up while in queue.

This statistic includes:

a) Calls answered by agent.b) Calls that are not answered by an agent and go to final destination.c) Calls that are sent to the UCD group but callers hang up before being answered.

LONGEST QUEUE TIME TODAYThis shows the longest call in queue today. The queue time is calculated as fol-lows:

a) Queue time begins when a caller starts to hear the first UCD message.b) Queue time ends when a caller is either

• Answered by an agent• System gets disconnected from C.O. or• Caller is transferred to final destination

LONGEST QUEUE TIME NOWThis shows the longest call currently in queue. The queue time is calculated asfollows:

a) Queue time begins when a caller starts to hear the first UCD message.b) Queue time ends when a caller is either

• Answered by an agent• System gets disconnected from C.O. or• Caller is transferred to final destination

4.8 AGENT STATISTICSLOGGED IN

The number of stations programmed in the UCD group and the number of stationsthat are currently logged in.


STATUSThis screen shows the agents name, extension number and status. The status canbe In Group, Out of group or in DND.


CALLS ANSWEREDThe total number of calls answered by the agent. This does not include ring noanswer to an agent station.

If this total number is less than the calls received by the group it is possible thatcalls were unanswered by an agent and went to final destination or that callershung up while in queue.

If this total number is more than the calls received by the group it is possible thatcalls were transferred from one agent to another.

AVERAGE CALL TIMEThis is an average of all the call durations for the agent

AVERAGE RING TIMEThis is an average of all the ring times for the agent. Ring times are previouslyexplained.
