PART 1. SYSTEM OVERVIEW

1.1 INTRODUCTIONThe DS 616, Digital Communication System, is a digital telephone system designed forthe small to medium-size businesses. DS 616 is easy to install and maintain, convenientto use and flexible to accommodate a variety of features. The system employs the verylatest DSP technology (Digital Signal Processors).

DS 616 provides interface cards that allow connection to the public telephone network orprivate networks. These are generally referred to as trunk cards. In addition to the trunkcards the system provides option boards for serial interface and auto attendant. Two typesof telephones can be connected to the systems. Proprietary digital phones called “keyset”connect to digital line interface (DLI) ports of the system. Standard telephone sets gener-ally called “Single Line Sets” connect to single line interface (SLI) ports of the system. Inaddition, DLI station ports are used to connect peripheral devices such as door-phoneinterface modules. Miscellaneous circuits are provided to allow such optional features asexternal paging, music on hold, background music and general-purpose dry contact.

All DS 616 keysets utilize a single PCB with surface-mounted components assuring thehighest product quality and long life. In many instances, sophisticated features are madesimple through the use of friendly display prompts or push-on/push-off feature keys.

1.2 SIZE AND CONFIGURATIONThe DS 616 consists of the Basic Key Service Unit (KSU), option boards, trunk interfacecards, interface modules, and digital keysets. The Key Service Unit (KSU) is a single metalcabinet and it begins with 16 station ports: twelve (12) keyset ports and four (4) SLT (singleline telephone) ports. Besides, the Basic Key Service Unit (KSU) contains one (1) trunkexpansion slot, two option connections and miscellaneous circuits: one (1) external pageinterface, one (1) general-purpose dry contact and one (1) music interface selectable tointernal built-in music (a melody chip) or external music.

Two types of telephones can be connected to the system: proprietary digital stations called“keysets” that connect to DLI (Digital Line Interface) ports and standard telephone sets,generally called “single line telephones”, that connect to SLI (Single Line Interface) ports.

The trunk expansion slot provides an option to select a S3TRK or S6TRK card.

The DS 616 allows two (2) option boards. One provides two (2) serial I/O ports, with ana-log Caller ID (FSK) decoder (a DSP chip), the second provides AA facilities.

The KSU basic configuration of 16 station is expandable via the trunk expansion slot. Themaximum capacity with analog trunks is 6 CO lines and 16 stations.

CONFIGURATION NOTES

1. The DS 616 does not support the installation of KDbs (Keyset Daughter Boards) foradditional DLI or SLI expansion.

2. Only one (1) trunk expansion card is possible3. Only one (1) SIO option board and one AA option board are possible.4. The system cannot accommodate any cards of other Samsung Digital Systems ex-

cept for the 3 TRK and 6 TRK boards.5. The analog Caller-ID presentation facility requires the special-designed SIO option

board (SIO-2) as well as an analog trunk card (a 3TRK or 6 TRK card).

The DS 616 system has only one expansion slot dedicated to a trunk expansion card:

DS 616 SYSTEM CONFIGURATION

1.3 TECHNOLOGY

SWITCHINGSystem switching is accomplished by means of a custom IC “engine” that provides 256switchable digital channels. The engine is controlled by its own 16-bit Motorola® MC68000 microprocessor and switching control program. Each of the 256 digital channels isautomatically assigned to carry voice or data as required by system operation in a PCMformat.

In addition to the 256 channels mentioned above, the systems also utilize Digital SignalProcessors (DSPs). Each DSP may be configured by the switching control program as aDTMF sender, a DTMF receiver or as a C.O. tone detector on a per-call basis. DS 616 isequipped with one engine chip which contains four (4) DSP channels. The DSP channelsare fully shared throughout the system as a common resource.

MEMORYThe systems operate using stored program control. This program is stored in EPROMchips. All specific customer data is stored in random access memory (RAM) which isprotected against the loss of AC power to the system by an on-board battery backupsystem. It is protected by a super capacitor providing 7 days of memory protection.

MICROPROCESSORSThe DS 616 uses distributed processing. The system’s primary processor is a 16 bitMotorola® MC68000 operating at a clock speed of 8MHz. The secondary level of pro-cessing is done in the keysets. The digital keyset uses a Hitachi H8 processor for datacommunication within the DS 616.

1.4 PROGRAMMINGThe DS 616 is self-configuring. This means that when the power is switched ON, the sys-tem reads the types and locations of all installed cards and telephones and assigns de-fault data to them. This data provides for system operation within seconds after power isswitched ON. All trunks and stations are assigned according to the default numberingplan. This numbering plan is flexible and may be changed to suit customer requirements.The installing technician customizes these default data to meet the end user’s require-ments.

The systems can be programmed from any LCD display keyset without interrupting sys-tem operation. There are three levels of programming: technician, customer and station.The technician level has access to all programs and can allow the customer access tosystem programs as needed. Technician and customer access is controlled by differentsecurity passcodes and access procedures.

DS 616 also allows the use of a proprietary computer program called PCMMC. This per-mits a technician to program the system using a personal computer. PCMMC can be used

1.5

on-site to modify the customer database or to download (save) the entire customer data-base to a file. This file can then be saved as a backup and be uploaded when required torestore the database. Through the use of modems, PCMMC can access a DS 616 systemremotely (off-site) to make database changes or perform uploads or downloads of thecustomer database as if the technician were on-site.

4.1 SYSTEM FEATURE DESCRIPTIONS

ACCOUNT CODE ENTRYStation 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 interruptinga conversation. Single line telephone users must temporarily interrupt the call byhook-flashing and dialing the feature access code. Account codes can be up to 12digits long.

FORCEDWhen forced, they are always verified from a system list of 200 entries. Accountcodes are always printed on the SMDR report. They can contain digits 0–9.

VOLUNTARYUsers may elect to enter an account code for any call. When a user voluntarily dialsan account code it is only verified from the system list of 500 entries when the ACCTkey is pressed before the call is made. If the ACCT key is pressed during a call theaccount number is not verified. 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 12 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 30 entries.

4.3

VOLUNTARYAny station user can always enter an authorization code before they begin dialing.The dialed authorization code is verified from a system list of 30 entries.

AUTO ATTENDANTThe DS AA card for the DS 616 includes four ports of auto attendant for simulta-neous answering and call processing. Sixteen professionally recorded promptsinform callers of the progress of their calls. Several examples are the following:“I’m sorry. There is no answer”, “That station is busy” and “Invalid number. Pleasetry again”, Two minutes of battery-backed random access memory (RAM) provideup to 48 customer recordings for announcements or greetings. Twelve individualgreeting boxes, each with its own dialing options, allow you to build call routingbranches as needed. Callers are routed through the branches by dialing exten-sion numbers or 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 the transfer key, conference key, page key or a DSS keyalways automatically places a C.O. call on hold. Intercom calls can be automati-cally held only by pressing the transfer key or the conference key. Each keyset usercan enable or disable Automatic 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 of avolume control program at the selected keyset.

BATTERY BACKUP (MEMORY)In 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.

BATTERY BACKUP (SYSTEM)Connect a customer-provided 48 VDC battery source and the system is fully opera-tional when AC power is interrupted. When power is restored, the system rechargesthe batteries. Calls in progress are not interrupted when the system switches tobatteries.

4.4

CALLER IDENTIFICATION

CALLER IDCaller ID requires that the SIO2 card be installed in the DS 616 KSU. Caller ID ser-vice must also be provided by your local telephone company. The availability ofthe calling party name or number depends on the type of CID service offered byyour local telephone company. The Caller ID feature is dependent on having anLCD keyset to show the name or number in the top line of the display.

NAME/NUMBER DISPLAYEach 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, theNND key 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 nextcall in queue at your station. Either the CID name or CID number will show in thedisplay depending on your NND 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. Pressing theSAVE number redial key will dial the CID number. The system must be using LeastCost 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, youmay view the Caller ID information before you retrieve the call. This will influencehow you 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 (100)The system has a system-wide abandon call list that stores CID information for thelast 100 calls that rang but were not answered. The list is accessed using theoperator’s passcode. When reviewing this list, you are provided options to CLEARthe entry or DIAL the number. You can use the NND key to toggle between the CIDname, CID number and the date and time the call came in. The system must beusing LCR to dial 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.

NUMBER TO NAME TRANSLATION (200)

The system provides a translation table for 200 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 deluxeCaller ID 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 CALLSThis 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 transfer key lights steady when a ForwardAll condition is set.

BUSY

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

4.5

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 is pro-grammable on a per-station basis to allow for differences in individual work habits.

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.

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

EXCLUSIVEOutside 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.

SYSTEMOutside 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.

REMOTEOutside 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 time

4.6

for 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 (8)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 8 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.

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 orchain together as many speed dial numbers as are required.

CLASS OF SERVICE (Day/Night)The system allows a maximum of 10 station classes of service. Each class of ser-vice can be customized in memory to allow or deny access to features and to de-fine a station’s dialing class. Each station can be assigned different classes ofservice for day and night operation.

COMMON BELL CONTROLThe system is equipped with one programmable relay. This relay provides a drycontact pair to control a customer-provided bell or common audible device. Thiscontact must be programmed as a member of a station group and may providesteady or interrupted 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.

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 DS 616 C.O. ringingpattern instead of intercom ring pattern. Devices connected to an SLI card receivea disconnect 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.

DAY/NIGHT RING ASSIGNMENTSEach C.O. line may be programmed to ring selected stations during day operationand different stations when the system is placed in night service.

DIL TO A HUNT GROUPLines may be programmed as direct in lines (DIL) to a station hunt group. Forexample, service parts or sales lines can ring directly to the designated depart-ments for immediate answer.

DIRECT INWARD SYSTEM ACCESS (DISA)Users can call in on specific DISA lines at any time, input a security code and re-ceive 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 may

4.8

be 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.

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 thetime that DISA is disabled are programmable. In addition, all failed attempts toaccess DISA 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 answeredwithin a programmable time, the system releases the door phone and stops theringing. 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.

4.9

4.10

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”so that 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 FEDERAL LAWSCONCERNING THE RIGHT TO PRIVACY. SAMSUNG TELECOMMUNICATIONSAMERICA IS IN NO WAY RESPONSIBLE FOR THE POSSIBLE MISUSE OF THISFEATURE.

EXECUTIVE/SECRETARY POOLINGEach keyset may be defined as a BOSS or a SECRETARY in system programming.Each BOSS can have up to four SECRETARIES and each SECRETARY can haveup to four BOSSES. These arrangements are known as executive/secretary pools.There can be multiple pools in a system. When a BOSS is in DND, all calls to theBOSS ring the first SECRETARY assigned to that BOSS; if that SECRETARY is busy,the call hunt to the next available SECRETARY assigned to that BOSS. If the SEC-RETARY must communicate with the BOSS while he/she is in DND, pressing thecorresponding BOSS button on the SECRETARY’s keyset results in an Auto An-swer intercom call being made to the BOSS (providing the BOSS is free). A stationcan only be the BOSS of one SECRETARY pool. In addition, a station cannot be inmore than one pool.

EXTERNAL MUSIC INTERFACEThe system provides an interface for connecting a customer-provided externalmusic source. This interface can be used for background music, station music onhold or trunk music on hold.

EXTERNAL PAGE INTERFACEThe system provides an interface for connecting customer provided external pag-ing equipment. This interface has s 600 ohm impedance.

4.11

FAX COMPATIBILITYBy connecting the facsimile machine to any single line station port, there is noneed for a dedicated FAX line. Incoming calls can be manually transferred to thefacsimile machine. Any line in the system may be selected to send a FAX.

FLASH KEY OPERATIONWhile a user is on an outside line, pressing the FLASH key will flash the central office orPBX. 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 two sec-onds 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 user guidesare 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.

HOLD RECALL TO OPERATORLines left on hold will recall the stations that put them on hold after a preprogrammedperiod of time. If the station does not answer the recall, it will return to the systemoperator.

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 al-lows all members of the group to share the call load.

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 dial-ing out as well as allow or deny answering for each outside line.

INTERNAL PAGE (FOUR ZONES)Any keyset may be assigned to one of four internal page zones. Any station maypage the keyset speakers in any zone using the corresponding access code. Bydialing internal paging access code, then ✱, all internal zones are accessed.

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 DS 616LCR program includes the following features:

! Option to use or not use LCR on 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

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.

LOUD BELL CONTROLConnecting any audible device (that operates on a normal tip and ring circuit) to asingle line station port will provide external loud ringing of incoming calls. Foradded flexibility, this station port may be programmed for both day and night ring-ing.

4.12

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.

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—FLEXIBLEThe system provides for either an external music on hold device, internally-gener-ated tones or no music, to be received by stations or C.O. lines placed on hold. If noservice is desired, each station/trunk can be programmed to receive either a 50ms tone or no music. The system generated tone is a beep every 3.5 seconds.

NIGHT SERVICEThe DS 616 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.

MANUAL

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

OFF-HOOK CALL ALERTUsers may call a busy keyset and offer it another call by sending an off-hook ringsignal. Busy stations may also be alerted to important or emergency calls by re-ceiving a ring burst each time the DSS key is pressed.

OPERATOR GROUPThe operator group can contain 16 stations to answer incoming calls. Calls to thisgroup can be set for distributed, sequential or unconditional ringing. Operatorscan use the In/Out of Group feature to meet flexible operator requirements.

4.13

OUTGOING CALL RESTRICTIONSelected stations may be restricted from placing outside calls. They can, however,receive calls.

OVERFLOW

OPERATORWhen 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.

PAGINGThe system software allows the use of four (4) internal and one (1) external pagingzones. Stations can page, all internal zones, the external zone or all zones simulta-neously. Using system programming, each station may be allowed or denied theabilities to make and/or receive page announcements to any zone or combinationof zones.

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.

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.

4.14

4.15

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 beneeded to implement this feature.

RING GENERATORThe system provides ringing voltage required for single line telephones and othertip and ring devices. The ring generator needed to ring single line telephones isbuilt into the basic power supply so that there is no need for additional purchase ofoptional equipment.

RING OVER PAGEAny outside line can be programmed to ring over a customer-provided pagingsystem. Outside lines, door phones and station groups may ring over page in theday or 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 equip-ment to these extensions, compatibility should be checked out before purchase toensure correct operation. Central office ring cadence can be selected for SLT sta-tions. This is helpful when optional devices cannot detect DS 616 intercom ringcadence.

SPEED DIAL NUMBERS (500)A library of 500 speed dial numbers may be allocated as needed. The system listcan have up to 300 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 24 digits.

SPEED DIAL BY DIRECTORYThe DS 616 system provides the user with the ability to look up a speed dial num-ber and place the call. There are three speed dial selections: personal, systemand station. This feature can be used with the soft keys on the display keysets or asa programmable button.

STATION HUNT GROUPS (10)System programming allows up to 10 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 16 stations. A station may be as-signed to more than one group. The default directory numbers to call these groupsare 501–509. 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.

4.16

STATION MESSAGE DETAIL RECORDING (SMDR)The system provides, via the optional SIO2 card records of calls made, receivedand transferred. Connecting a customer-provided printer or call accounting sys-tem will allow collection of these records. Each call record provides the followingdetails: station number, outside line number, start date, start time, duration of call,digits dialed (maximum 18) and an account code if entered. The system may printa header followed by 50 call records per page or send continuous records with noheader for use with a call accounting machine.

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.

SVM 400–VOICE MAIL INTEGRATIONSVM 400, a proprietary Samsung Voice Mail System, offers a direct link to the DS616, via DLI ports, for complete voice mail operation. Utilizing DLI ports for integra-tion to the DS 616, the SVM 400 uses the same IPC messaging as the DS 616. Thisdesign creates smoother, more accurate operation.

The SVM 400 can also be used for Auto Attendant functionality, to compliment thevoice mail system, or as a stand alone Auto Attendant.

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.

TOLL RESTRICTIONThere are 200 allow and 200 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 allowedor denied on a per-class basis. Class A stations have no dialing restrictions andClass H 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 telephone com-pany 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.

4.17

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 the sys-tem. Transfers can be screened, unscreened or camped-on to a busy station.

TRUNK GROUPS (3)Outside lines can be grouped for easy access by dialing a code or pressing abutton. There are 3 trunk groups available. Access codes are 9 and 80–82.

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.

UNLISTED SPEED DIAL NUMBERSSystem speed dial numbers 90–99 and each station user’s personal speed dialnumbers 1 and 2 will not be displayed when used. This will ensure the privacy ofthese telephone numbers and prevent unauthorized use. However, they will beprinted out on the SMDR report.

VOICE MAIL INTEGRATIONThe DS 616 system uses DTMF tones (inband signaling) to communicate with anycompatible 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.

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 authorization codefeature. Both methods change the class of service to correspond with the stationpasscode or authorization code that is dialed. After the call is completed, the sta-tion returns to its programmed class of service.

AUTO ANSWERWhen an 616 station is set into this mode, all intercom calls will automatically turnon the speaker and microphone for true hands-free answering. Each 616 keysetuser may select either this mode or ring mode.

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. Pressingthe transfer key, conference key, page key or a DSS key will always automaticallyplace the call on 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 a customer-provided music source is connected, each keyset user may lis-ten to background music. The HOLD button turns BGM on or off and the volume iscontrolled by the volume control keys. The music interface is located in the KSU.

BUSY LAMP FIELD (BLF)DSS/BLF keys are assigned by default to all keysets. These buttons will be offwhen the station is idle, light red when that station is in use and flash distinctivelywhen that station is in the DND mode.

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).

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 a For-ward All condition from his/her station to another station while at the remote station.

4.20

To display the Follow Me condition, the transfer key lights steady red at the stationthat is forwarded. The transfer key also lights if Forward All is set and no key isprogrammed 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 followor 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.

FORWARD DNDForward DND allows calls to a station in Do Not Disturb or One Time Do Not Dis-turb, to be forward immediately to another destination.

CALL PICKUPWith directed call pickup, a user can answer calls ringing at any station by dialinga code plus that extension number. The group pickup feature allows the user toanswer any call ringing within a pickup group. Pickup keys may be customizedwith extenders to allow pickup from a specific station or pickup group. The DS 616has 8 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 throughthe directory name list. This on-line “directory” allows the user to look up and dialnumbers in seconds.

DIRECT STATION SELECTION (DSS)By default, all stations are programmed with DSS keys, which are associated withthe other extension numbers in the system. Users press these keys to call or trans-fer calls to the assigned stations.

DO NOT DISTURB (PROGRAMMABLE)The Do Not Disturb (DND) feature is used to stop all calls to a station. System pro-gramming can allow or deny use of the DND feature for each station. Parties callinga station in DND will receive reorder tone. When in DND mode, calls may be for-warded to another destination. See Forward DND option. A keyset without a DNDbutton can activate DND via the feature access code. The ANS/RLS key will flash at112 ipm (rapidly) when DND is set.

There is a programmable option to allow a C.O. line to override DND at its ringdestination if that destination is a single station.

4.21

DOOR LOCK RELEASEStations programmed to receive calls from a door phone can dial a code to acti-vate a 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 allows agroup of people to listen to the distant party over the speaker without the micro-phone turned on.

HANDSET VOLUME CONTROLFor added convenience and comfort, the volume of the handset receiver can beadjusted on every keyset by pressing the volume UP/DOWN keys.

HEADSET OPERATIONEvery keyset can be programmed to allow the use of a headset. In the headsetmode, the hookswitch is disabled and the SPEAKER key is used to answer andrelease 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 SPEAKER key lights ifheadset mode is activated by keyset programming only.

HEARING AID COMPATIBLEAll DS 616 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 stationor group of stations.

4.22

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.

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 forfast accurate 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 KEYSThe DS 24D keysets have 24 programmable keys. By default, keys 1–6 are as-signed a Direct Trunk keys. Key 7 is not assigned and key 8 is assigned as a MSGkey. Keys 9–24 are assigned as DSS keys and are associated with the other exten-sions in the system.

Each key can be programmed for more than 25 different uses to personalize eachphone. Examples of keys include individual outside line, individual station, groupof lines, group of stations and one touch speed dial buttons. Using these keyseliminates 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, FORWARD

4.23

and VOICE MAIL TRANSFER. The extender can be a station, a group or anotheridentifying 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.

PROTECTION FROM BARGE-INEach station can be programmed as secure or not secure. Secure stations cannotbe barged-in on. A station that is not secure cannot be barged-in on when talkingto a secure station.

PULSE TO TONE SWITCHOVERWhen dialing a number on a dial pulse network, a station user can dial # and theDS 616 system will begin to send DTMF.

REDIALThere are three types of external redial available to all station users. Each type canredial up to a maximum of 18 digits.

! AUTO RETRY—When an outside number is dialed and a busy signal is received,the auto retry feature can be used to reserve the outside line and automaticallyredial the number for a programmable number of attempts.

! LAST NUMBER—The most recently dialed number on a C.O. line is saved andmay be redialed by pressing the redial key or dialing the LNR access code.

! SAVE NUMBER—Any number dialed on a C.O. line may be saved for redial ata later time.

REMOTE HOLDWhen you wish to place a call on hold at another station, press TRSF and dial thestation number (or press the appropriate DSS key). Press the HOLD key. This willplace the call on system hold on an available CALL button or Line Key at the re-mote station.

RING MODESEach keyset user can select one of three distinct ways to receive intercom calls.The phone can automatically answer on the speakerphone, voice announce throughthe speaker or receive ringing. When the ring mode is selected, keyset users canchoose one of eight distinct ring tones. Forced Auto Answer is invoked by the call-ing station and is controlled by the calling station’s class of service.

4.24

RINGING PREFERENCELifting the handset or pressing the speaker button automatically answers a callringing at the keyset. Using this method, users are assured of answering the oldestcall first. When ringing preference is turned off, the user must press the flashingbutton to answer. Users may answer ringing lines in any order by pressing theflashing button.

SPEAKERPHONEThe DS 24D keysets have a built-in speakerphone. The speakerphone enablescalls to be made and received without the use of the handset.

STATION CALLBACKWhen the user reaches a busy station, a callback may be requested. The systemrings the calling station back when the called station becomes idle.

STATION LOCKWith a programmable personal station passcode, any keyset can be locked andunlocked. A locked keyset cannot be used to make or receive calls.
