Introduction The TxPORT PRISM 3001 (Figure 1-1) is a modular, single port, fractional T1 CSU/DSU. The unit allows connection of high-speed digital data to a T1 facility. V.35- or EIA530- compatible high-speed port interfaces are available which support port rates from 56 kbps to 1.536 Mbps. The interface to the T1 network is made through an integral ESF CSU which provides full performance monitoring of the T1 span and is compliant with T1.403, TR62411, and TR54016.

The unit is available with a second DSX1 level T1 interface to support drop aninsert applications. Network bandwidth may be allocated as needed between thigh-speed data port and the T1 DTE port, allowing the integration of data andvoice traffic across a single T1 facility.

The TxPORT PRISM 3001 provides the powerful feature set of the multiport TxPORT PRISM 3000 in one of the most compact packages in the industry. T3001 module can be installed in either a single unit housing or in the 1051-2 mount chassis which holds up to twelve units. Power supplies are available to the requirements of small to large installations, including full redundancy.

The unit may be controlled through a VT100 terminal or a computer with ANSterminal emulation software. If used with the EM8000 Element Manager or 810Site Controller, the entire T1 network can be monitored and controlled from a central location.

LED indicators are provided on the front panel of the unit to alert local personof alarm conditions, loop and test status, and DTE port activity. A test switch allows local and remote loops to be activated as well as BERT tests. Althoughconfiguration parameters are software selectable from the terminal interface onetwork manager, configuration switches are provided on the unit to allow operation without the use of a management interface.

Introduction This chapter contains information and instructions required to prepare the TxPPRISM 3001 for use. Included are initial inspection procedures, mounting instructions, configuration guidelines, connection instructions, and powering information.

Throughout this manual, all factory default settings are shown underlined.

SafetySummary

This manual contains information and warnings which must be followed to enssafe operation and to retain the equipment in a safe condition.

The WARNING sign denotes a hazard to the operator. It calls attention to a procedure or practice which, if not correctly performed or adhered to, could result in injury or loss of life. Do not proceed beyond a WARNING sign until the indicated

conditions are fully understood and met.

Follow proper ESD (electrostatic discharge) procedures while handling the circuit boards.

UnpackingandInspection

This unit is carefully packaged to prevent damage in shipment. Upon receipt, inspect the shipping container for damage. If the shipping container or cushiomaterial is damaged, notify the carrier immediately and make a notation on thdelivery receipt that the container was damaged (if possible, obtain the signatand name of the person making delivery). Retain the packaging material until contents of the shipment have been checked for completeness and the instruhas been checked both mechanically and electrically.

If the contents of the shipment are incomplete or, if there is mechanical damagdefect, notify TxPORT. If the shipping container is also damaged, or the cushioning material shows signs of stress, notify the carrier of the damage asas TxPORT. Keep the shipping materials for carrier’s inspection. TxPORT will arrange for repair or replacement without waiting for claim settlement.

For specific applications, additional cables and adapters may be required. Theinterface requirements of any application may be met by using the appropriatecable. Contact TxPORT for any needed assistance in cable selection.

Mounting The 3001 is a modular unit that plugs into either a single unit housing or into chassis that holds up to 12 units. Single units are designed for stand-alone deuse, wall mounting, or chassis mounting (in either a vertical or horizontal orientation). The 3001 uses an interchangeable front panel to accommodate tchassis card cage.

Stand-aloneUnit

To access the circuit boards and configuration switches, perform the followingprocedure. Observe proper electrostatic device handling procedures while holthe circuit boards.

1 Open the front panel access door and remove it by gently bending the plastic the middle using both hands.

2 Pull the two side strips of plastic from the middle outwards until the four stopsclear of the front panel.

3 Pull the cover off the front panel.

4 Remove the two screws and pull the front panel and circuit boards out of the housing.

The stand-alone unit may be used in a chassis installation with the following modifications.

1 Remove the housing as described above and then remove the four screws hothe front panel to the circuit boards.

2 Replace the stand-alone front panel with a module type front panel.

The unit can now slide into one of the 12 slots in the chassis.

ChassisAssembly

Up to twelve PRISM 3001 units may be inserted into a chassis and the chassmay be installed into a 19- or 23-inch rack using four screws. Connections aremade from the rear of the chassis (refer to the illustrations on page 2-9).

UnitConfiguration

The PRISM 3001 can be software configured in the same manner as the mulPRISM 3000 by using a terminal connection to either the front panel Supervisaccess port or the rear panel NMS IN port. The TxPORT EM8000 Element Manager and 8100A Site Controller may also be used to configure the unit byusing the same ports. The terminal interface, element manager, and site contrprovide a broader set of capabilities than by using the configuration switches.

The 3001 provides non-volatile memory retention of unit configuration in the event of power failure. This feature allows the unit to automatically restore norservice following a power loss. Note, however, that when the unit is stored withpower for an extended period, the battery may drain and some parameters mbecome corrupted.

Therefore, when the unit is first received for installation or if power has not beapplied for an extended period of time, the configuration should be verified useither the terminal interface, element manager, or site controller. The battery becomes fully charged after power has been applied for 160 hours.

Hardware switches on the side of the circuit boards provide the means to confmost simple applications. These configuration switches are described in the following paragraphs. When power is applied to the unit, the front panel indicaflash for approximately 10 seconds as the unit executes a self-test function. Ifambiguous configuration has been programmed, the front panel indicators conto flash after the self-test is completed. The configuration must then be reviewto correct the error.

The unit is hardware configured using three DIP switches, a rotary switch, andjumpers. All are located on the top edge of the circuit boards (refer to Figure 2above). The front panel rotary switch selects BERT patterns and is described iOperations chapter. The numbering system used for each switch position is asfollows: Position 2 of Switch S4 is referred to as Switch S4-2, and so on.

Before installation, verify each configuration switch setting. A removable configuration guide is included in the rear of this manual to record option selections for reference.

ConfigurationSwitch S4

Switch S4 is used to set the configuration parameters listed in the following paragraphs.

Network Coding

Position S4-2 sets the network line coding to AMI or B8ZS.

Down: AMI Up: B8ZS

Network LBO

Positions S4-3 and S4-4 set the line build out signal level of the transmit data(TXD) from the unit to the network. The output level is factory set at 0 dB. It may be attenuated by -7.5 dB, -15 dB, or -22.5 dB if operating conditions require it be changed. The telco should provide the proper setting to the user. If unsure of the exact setting, then leave it at the default value. The values are listed in thfollowing table.

Bit Rates

Position S4-5 works in conjunction with rotary switch S7 to set bit rate configurations. Refer to Rotary Switch S7 on page 2-7 for further information. Tmissing rates are N×56 and N×64, where N=15,17, 21, and 23. All 24 rate configurations can be programmed through software control by using the NMSSUPV ports.

Clock Source

Positions S4-6 and S4-7 determine the source of unit clocking. The most comtiming source for most CSU/DSU applications is to derive timing from the network. The 3001 may also be optioned to time from an internal standard, frothe T1 DTE, or from the high-speed data interface as shown in Table 2-2.

Channel Assignment

Position S4-8 selects the channel assignment mode for network T1 DS0s thacarry data to the high-speed port. Contiguous assignment assigns the channels asblock beginning at channel one. For example, if the high-speed port data ratebe 256 kbps (as defined by rotary switch S7 in on page 2-7), the unit would assign network channels 1 through 4 to the high-speed port.

If the Alternate channel mode is selected, channel assignments are made withidle channel following each data channel. For the above example, data would carried on channels 1, 3, 5, and 7 and channels 2, 4, 6, and 8 would be set idto binary code 01111111). The advantage of alternate channel assignment is T1 ones density requirements are maintained by the idle channels rather that placing any restrictions on the high-speed data.

AddressSwitch S5

Switch S5 is used to set the unit address. When using the EM8000 Element Manager, 8100A Site Controller, or other network manager controlled productswith the 3001, each element in a group must have a unique unit address. Up tunits (with addresses from 1 to 250) can exist in a group. If the unit is not connected to a network manager, the NMS unit address should be left at the factory default setting of 1.

Switch S5 has 8 positions used to create an 8-bit binary code for an address range of 1 to 252. Switch position S5-1 is the least significant bit (LSB) and Sis the most significant bit (MSB). If a switch is down, its value is 0 and if it is uits value is that of the upper location. The values are additive. For example, to unit address to five (5), position S5-3 (binary value = 4) and position S5-1 (binvalue = 1) would be set Up for a unit address of 5 (4 + 1). All other positions would be set down.

20 out of the 24 possible bit rate configurations are available through these hardware settings. The missing rates are N×56 and N×64, where N = 15, 17, 21, and 23. All 24 rate configurations can be programmed through software controusing the NMS or supervisory ports. The terminal interface program also allowthe high-speed port to be mapped to a block of DS0s that begins at a user- selectable starting channel.

For units equipped with the T1 DTE port option, channel numbers beyond those assto the high-speed port are automatically mapped through to the T1 DTE. In the altechannel mode, every data channel is followed by an idle channel assignment. Therthe even channels are quiet and are not available to the T1 DTE port.

SupervisoryPortConnection

The front panel supervisory port serves several functions. A modem may be connected to the SUPV port for remote access or use of the COA (call on alarm) feature. For cabling convenience, the supervisory port may be used to connect the element manager into the 3001 network (refer to NMS Connection on page 2-10).

The supervisory port bit rate is set by configuration Switch S6. The port is a serial RS-232 DCE port configured for 8 bits, no parity, and 1 stop bit. The physical connection is a 6-pin modular jack with the pinout shown in Table 2-8.

High-speedPortConnection

The high-speed port connection [on the rear panel of both the stand-alone (Figure 2-6) and the chassis unit (Figure 2-11)] utilizes a female subminiature DB-25 connector. If the unit is connected to an EIA-530 DTE-type device, a one-to-one DB-25 cable is all that is needed. If the unit is connected to an RS449-compatible interface, an adapter cable must be used to match the 37-RS-449 standard. The V.35 option also requires an appropriate adapter cable connect to devices that use the standard 34-pin V.35 interface. Pin functions fthe high-speed port interface are listed in Table 2-9.

NMSConnection

The PRISM 3001 is fully compatible with the TxPORT EM8000 Element Manaand 8100A Site Controller. The EM8000 and 8100A software systems are usemanage small to large networks of TxPORT network access products.

An element may be accessed by using an RS-232 connection from the serial of the computer running the EM8000 program to the element’s SUPV port or NMS IN and NMS OUT ports. The different connection methods are describethe following paragraphs.

SUPV The EM8000 workstation or the 8100A Site Controller may be directly connecto the 6-pin modular serial port connector labeled SUPV (also refer to SuperviPort Connection on page 2-9). When a group of elements is connected in an chain, the EM8000 or 8100A may be connected to the supervisory port of anyof the elements. This element can then route messages onto the NMS chain reach the other elements. The call on alarm (COA) feature works through the SUPV port only.

NMSIN/OUT

The two 6-pin modular connectors labeled NMS IN and NMS OUT on the reapanel may be used for connection to the EM8000 or 8100A. This port is configured in this manner to allow the connection of multiple collocated units idaisy chain IN/OUT bus arrangement as shown in Figure 2-7. The OUT port oone element is connected to the IN port of the next element, and so on, to forcomplete chain among the group of elements.

NMSSplit Cable

The EM8000 may be connected directly into the NMS chain between two elemif connection to the SUPV port is not desirable. A Y-cable is used from the EM8000 serial port which splits the transmit and receive signals into two 6-pinmodular connectors for the NMS IN and NMS OUT ports. Ordering informatiofor this cable is found in Table 1-2 on page 1-8.

NMS INOnly

The NMS IN connector provides both the transmit and receive signal pair. Thiport may be used for a modem connection or as a VT100 terminal interface (explained in the Terminal Operation chapter).

ChassisOperation

EM8000 and 8100A operation in the 12-slot chassis is similar to operation witthe stand-alone unit with the exception that all elements are already chained together in the chassis. The front panel SUPV and the rear panel NMS ports operate in the same fashion.

The NMS address, port bit rate, and power up configuration mode can be set by the configuration switches. The physical connection is a 6-pin modular connector with the following pinout. This port is a serial RS-232 DCE port configured for 8 bits, no parity, and 1 stop bit.

Introduction This chapter contains general operation instructions for the TxPORT PRISM 3front panel. The unit may be controlled manually using the front panel and thecircuit board configuration switches (configuration switches are discussed in thInstallation chapter).

The Terminal Operation chapter covers the firmware-controlled Terminal Interfprogram, which provides more control. The unit may also be controlled using TxPORT EM8000 Element Manager (refer to the EM8000 reference manual) 8100A Site Controller.

Front PanelControls andIndicators

The front panel contains 19 LED indicators which convey status, alarm, and teinformation. The front panel also contains a test switch, a supervisory port connector, and a BERT pattern switch. The following descriptions are referencto Figure 3-1.

GeneralStatus

Indicators

1 STATUS: The unit has two LED indicators on the front panel bezel that are exposed whether the access door is open or closed. These general status LEprovide a quick check of the unit’s operating condition (Go or No Go).

If neither LED is on, the unit is not powered. If the green LED is on, the unit ipowered and functioning normally. If the red LED is on, there is a line fault thexceeds alarm thresholds or another type of unit failure. The problem can be isolated by further examination of the other front panel LEDs as described in following paragraphs. NMS alarms are displayed by the two LEDs alternately turning red and green about every half second which occurs when the unit is managed by an 8100A that detects a duplicate address or invalid address (0 are valid). The 8100A detects these error conditions and notifies the unit to enan NMS-alarm condition. Once the error condition has cleared, (either the duplicate address is removed or an invalid address is corrected) the 8100A nothe unit to clear the NMS-alarm condition.

2 TD: This green LED lights during a mark condition on the high-speed transmidata line.

3 RD: This green LED lights during a mark condition on the high-speed receivedata line.

7 ACO: This yellow LED lights whenever the alarm cut off switch is placed in the left on position. It indicates that the alarm relay contacts are disabled.

8 ACO SW: The alarm cut off switch controls the alarm relay circuitry. If the switch is placed in the left on position, this circuitry is deactivated.

9 BV/CR / FE: This LED lights one second for each second that has an occurrence of bipolar violations (BPV), cyclic redundancy check (CRC) errors, or frame bit errors (FBE).

10 LOS/OOF: This LED blinks with a loss of signal (LOS) from the network. It lights constantly when an out of frame (OOF) condition is detected.

11 AIS: This alarm indication signal LED lights if an unframed all ones condition is detected from the network.

12 REM ALM: This LED lights constantly when a remote (yellow) alarm signal is received.

13 LOC ALM: This LED lights when a local alarm exceeding alarm thresholds exists.

Introduction This chapter describes the screens and menus associated with the TxPORT P3001 terminal interface, which is a firmware application program embedded inthe unit.

The terminal is connected to a 6-pin modular jack on the PRISM 3001. Refer to the Installation chapter for more information on user connections. Cables are available for most typical connections. Standard cables and ordering numberslisted in Table 1-2 on page 1-8. Contact TxPORT for any assistance in cable selection.

In addition to the 54016 and T1.403 protocols, proprietary messages can be sover the facility data link (FDL) from the near-end PRISM 3001 to the far-end PRISM 3001. A local RS-232 terminal connected to the unit may access a farPRISM 3001. Thus, the remote unit may be queried for status and statistics, configured, or looped for testing as if the terminal is connected to it directly.

SystemDescription

The terminal interface requires an ANSI-compatible VT100 terminal (ASCII), ocomputer running an ANSI terminal emulation program. The terminal interfaceuses ASCII break and escape functions, which are implemented differently wivarious terminal emulation programs. The software supplied with the emulatioprogram should be consulted for further reference.

The 3001 unit has two serial interface RS-232 ports. Either of these ports maused for the terminal interface program or as a connection to the EM8000 EleManager or an 8100A Site Controller. One port is a pair of daisychain-type repanel connectors labeled NMS IN and NMS OUT. The other port is located onfront panel and labeled SUPV. Serial bit rates of 1200, 2400, 9600, or 19200 may be selected using option switch S6 (refer to the SUPV and NMS port bit rates, Configuration Switch S6 on page 2-5).

Both serial ports support the same custom protocols that allow the terminal interface, EM8000, or 8100A to request and receive performance and configurdata from the unit. The unit automatically determines which protocol is needed

ModemCompatibility

The PRISM 3001 terminal interface supports the use of an AT-command-set- compatible modem on either, or both, of the NMS IN and SUPV serial ports. Tmodem should be optioned to ignore DTR, enable auto answer, inhibit commaecho, and return verbose result codes.

ScreenComponents

Terminal interface screens have several components common to all screens adiscussed individually in the following paragraphs. These common elements ashown in the Password Screen (see Figure 4-1).

Device Typeand Revision

The device type (PRISM 3001) and the revision control numbers are shown inupper left corner. The first number is the hardware revision and the second nuis the software revision. Information is displayed for the near-end unit (connecdirectly to the terminal) on the top line, and for the far-end unit (connected to network T1 interface) on the second line. Refer to this information when contacting the factory with inquiries.

The far-end information is available only for TxPORT products that support a proprietary message set. If the far end does not support these messages but support the standard 54016 protocol, then the far-end information is displayedGeneric 54016 Far End. If the far end does not respond to either proprietary o54016 messages, then No Far End Response is displayed.

Date/Time The top right corner of the terminal screen displays the current date and time.setting of these functions is described in Utilities Screen on page 4-21.

Element ID/Unit Address

Below the header, the Element ID is displayed (refer to Utilities Screen on pag4-21). Next to the Element ID is the units NMS address.

Menu Title The menu title (third line, center) denotes the general classification of functioncurrently accessible by the user (such as Alarms or Performance).

Messages The last line may display diagnostic messages.

InterfaceStart Up

Once a compatible terminal is properly connected to the 3001, the terminal interface is started by sending a Break to the unit. The Main Menu screen (Figure 4-2) is displayed if no password has been specified in the Utilities menRefer to Utilities Screen on page 4-21 for information on setting the passwordthe Password screen (Figure 4-1), the correct password must be entered to obaccess to any other menu.

CursorControls

The terminal interface utilizes a highlighted cursor to make selections from meand to select fields within screens to be operated upon. The cursor can be mousing the standard keyboard arrow keys (left, right, up, and down). Once a fiehighlighted, it is manipulated as described in Field Types below.

For keyboards that do not have these standard keys or have only some of thealternate set of cursor control commands is provided. Each of these is performby pressing a letter key while holding down the Control key. Alternate commanmay be freely mixed with the keyboard commands as desired. The alternate command keys are listed in Table 4-1.

FieldTypes

Each screen is made up of fields. The two basic types of fields are user-selecand display-only. If the highlighted cursor can be moved to a field, it is a user-selectable field. All other fields are display only. User-selectable fields allomaking changes or executing commands.

Fields without brackets or parenthesis are display-only fields. They cannot be changed on the screen. Most user-selectable fields are enclosed in brackets oparenthesis and are described in the following paragraphs. Any exceptions arnoted in the appropriate section of this manual.

Fields enclosed in brackets [ ] offer the user a list of selections from which tchoose. The selections may be toggled by pressing the spacebar. Each time spacebar is pressed, a new selection appears. When the appropriate choice apress Enter. In most cases, the new selection does not take effect until Enter pressed.

Fields enclosed in parenthesis ( ) are manipulated by one of the following twmethods:

Pressing Enter on such fields as (Reset) and (Start Test) execute the function

The most common type of field in parenthesis accepts typed input in the formletters and/or numbers. Typing characters when the field is highlighted causecurrent entry to be replaced with the new characters. To edit an existing entryrather than replace it, press the right arrow key to move the cursor to the poinneeds editing. Characters may then be inserted or deleted. Typed data is alwinserted rather than typed over. If the field is full, though, at least one charactmust be deleted to add another.

Many fields of this type may also be toggled by pressing the spacebar as welaccepting typed input. Other fields are range checked, where the user cannotthe screen with an illegal value set.

Any of the screens may be redisplayed or refreshed by pressing Control+U.

PerformanceScreens

The Performance screens display a detailed history of the error parameters thcontinuously monitored. The terminal interface provides display of near-end orfar-end performance data using the facility data link.

The unit has a dual set of performance data registers with individual resets thhold line statistics for both the telco and user. Each register set provides detaistatus and performance history for the network and DTE interfaces.

The system has four Performance screens. The STANDARD 24 HOUR and thENHANCED 24 HOUR screens allow the user to view the 24-hour detailed performance history of the T1 circuit. The only difference in these two screensin the performance data displayed. The STANDARD 24 HOUR screen is showFigure 4-5.

The STANDARD 30 DAY and the ENHANCED 30 DAY screens allow the user view a 30-day history of a particular elements performance. These screens reference intervals by date rather than by time. To reach each of the four scretypes, use the spacebar to toggle the STANDARD 24 HOUR field. The other fiare described as follows.

Element This field selects either the NEAR unit or the FAR unit as the source of performance data or the target of commands. NEAR refers to the unit to whichterminal is connected. FAR refers to the unit at the other end of the network Tspan. Use the spacebar to toggle this field.

Target This two-part field determines which section of the circuit is presently displayeby toggling the spacebar. Telco registers are for viewing only and may not be changed. The options are as follows.
