Introduction

The TXPORT PRISM 3010 - 400 DSU M P card provides a DDS interface for customer premises applications. The DSU MP card plugs into a single slot of the PRISM 3060- 10 modular chassis.

The DSU MP card comes with six DSUs (12 ports in TDM mode or 6 ports in standard modes).

All configuration for the card can be done in minutes. Configuration can be done through the front panel LCD, embedded VT100 user interface, through telnet, or the TXPORT 8100A Site Controller. The DSUs can be independently programmed for any of the available tim e slots.

The DSU MP card provides quick trouble isolation. The interface can be looped from any of the management interfaces. Bit error rate testing (BERT) can be generated and detected in either direction: toward the networ k in the assigned channel(s) as well as to the DTE equipment. Alarms are generated for both the network and DTE sides.

Inspection

This unit is carefully packaged to prevent damage in shipment. Upon receipt, inspect the shipping container for damage. If the shipping container or cushioning material is damaged, notify the carrier immediately and make a notation on the delivery receipt that the container was damaged (if possible, obtain the signature and name of the person making delivery). Retain the packaging material until the contents of the shipment have been checked for completeness and the instrument has been checked b oth me chanically and elect rically.

If the conten ts of the shipm ent are inco mplete or, if there is mechanical d amage or defect, notify TXPORT. If the shipping container is also damaged, or the cushioning material shows signs of stress, notify the carrier of the damage as well as TXPORT. Keep the shi pping material s for the carrier’s inspection. TXPORT will arrange for repair or replacement without waiting for a claim settlement.

The 3010 - 400 card fits into slots 3, 4, 5, or 6 of a 3060 -10.

To prevent electric shock or damage to the unit, turn the rear panel power switch OFF before removing or installing any option modules.

To add a module to an empty slot, power the unit off and remove the cover plate. Carefully slide the new card along the guides with the unit oriented as shown in Figure 2-2. Push the board in until the faceplate rests against the rear panel. Ensure that it se ats without displacing the flexcable connector. Then, insert the screws.

If resistance is encountered when inserting the card, remove the card and verify that there are no obstructions its path. Also check for bent or damaged pins in the connectors on either the module or the chassis.

Unit Configuration

DSU MP Port Connections

Configuration is performed using one of the following m ethods:

✦ The front panel LCD interface (see Chapter 3 of this manual). ✦ A term inal conn ected to th e SUP V or the NMS po rt (see C hapter 4 o f this

manual). The 3060-10 provides non- volatile memory retention of unit configuration in the

event of power failure. This feature allows the unit to automatically restore normal service following a power loss. Note, however, that when the unit is stored without power for an extended period, the battery may drain and some parameters may become corrupted.

Therefore, when the unit is first received for installation or if power has not been applied for an extended period of time, a factory-default maintenance reset operation should be performed on the unit. Refer to the procedures detailed in Maintenance Reset on page 16.

FCC rules require that interconnecting cables carrying high-speed data be shielded

appropriately to minimize radio frequency interference.

The DSU MP physical interface is two standard D-subminiature, 120 -pin female connectors (Figure 2-2) that break out with two of the cable assemblies (Figure 2-3). The pinout assignments are shown in Table 2-1.

Network Connection

The network side of the unit is referred to as the network interface. This interface contains an ALBO (automatic line build out) that allows the unit to be located a substantial distance away from the telco network interface with a receive signal level down to -27 decibels.

The network interface LBO level should be set as instructed in Line Build Out on page 19. Maximum suggested cable lengths for the connection from the unit to the network are listed in the following table. Calculations are based on a cable temperature of 70°F, 0.083-µF/mile capacitance, a 27-dB loss, and a 100-Ω, non-loaded, twisted pair cable. PIC refers to Plastic Insulated Cable.

In accordance with FCC Rules, Part 68.218 (b), the user must notify the telephone company before disconnecting the unit.

Alarm conditions detected by the unit are conveyed at the isolated Alarm Relay output contacts on the rear panel. NC (Normally Closed) and NO (Normally Open) refer to the alarm contact’s relationship to C (Common) under a no-alarms condition.

Alarm connections are made to the terminal strip using a 22- gauge stranded, or similar wi re. The Normally Closed alarm co nnects to NC & C. The Normally Open alarm connects to NO & C. Contacts a re rated at 0.6 amperes AC or 2.0 amperes DC . Alarm parameters are discussed on page 55.

If the unit is to receive its timing source from a user-supplied clock other than the DTE or T1 lines, the Station Clock input must be connected on the rear panel. This input is designed to accept TTL or bipolar signal levels. The station clock is commonly available as a 64 kHz, bipolar RTZ signal referred to as a composite clock.

Network M anagement 11

The unit also accepts any unframed all-ones bipolar RTZ signal with a level of 1.5 to 4 volts peak and a frequency of 1.544 MHz or any multiple of 56 or 64 kHz. An RS423-compatible station clock input, with the sa me range of input frequencies, is also available as an opti on.

The station timing is configured through the front panel (see Station Tim ing on page 20) or through the te rminal interface (see Station Timing on page 53). The pinout of the 6-pin modular jack is shown in the following table.

Figure 3-2 Idle Display Screen

The PRISM 3060 -10 provides non-volatile memory retention of unit configuration in the event of power failure. This feature allows the unit to automatically restore normal service following a power loss. Note, however, that when the unit is stored without power for an extended period, the battery may drain and some parameters may becom e corrup ted.

Therefore, when the unit is first received for installation or if power has not been applied for an extended period, a factory default maintenance reset operation should be performed. This is done by pressing and holding the CLR button a nd then applying power to the unit. Hold this key until the RAM CLEARED message appears. This procedure installs the predefined ROM configuration to eliminate the possibility of data corruption. The battery is fully charged after power has been applied for 120 hours.

The maintenance reset operation sets all parameters to the factory default ROM settings and zeros all perfor mance registers.

Password If no password has been programmed, the password prompt does not appear and

the PRISM 3060 -10 proceeds directly to the menu system. The unit is factory shipped without a programmed password. The process of setting a password is described in Edit Password on page 32.

If a password has been programmed, the password sc reen appears when any key is pressed. Each character must be entered using the up and down arrow keys until the desired charact er is di spla yed. Us ing the u p arrow, the characters s croll throu gh

Menu Title

The menu title is the general classification of functions currently accessible to the user.

Menu Element

There are three types of menu elements. In this manual, the distinction is made by the box type shown in the menu diagrams.

✦ A large, solid box indicates user-selectable menus with lower-level menu items. ✦ A dashed box lists user-selectable parameters. Pressing Select exe cutes the

displayed configuration.

✦ A small, solid box (with small type) indicates either a non- se lectable status or a

field in which a particular value may be entered. For example, refer to T1 NET Configuration Menu on page 19. The upper-level

menus are shown within a large, solid box. This indicates that these items are user-selectab le menus . The lower level menus are shown wit hin dash ed boxes to indicate that these items a re user-selec table para meters . The sma ll, solid b oxes under Alarm Thresholds indicate that values may be entered in these fields.

If the menu element contains a submenu, it is accessed by pressing Select. The menu element becomes the menu title and the next lower level in the hierarchy become s the men u elemen t. For exampl e, if the m enu e lement is T1 NET Configuration, pressing Select moves T1 NET Configuration up to the menu-title level and Framing Type moves up to the menu-element level.

The DTE Port Configuration display (Figure 3-9) allows configuration parameters to be set for the DSU MP ports.

It is very important that the DTE ports at opposite ends of a link be configured

identically. For example, if port A of one DSU MP is configured for 19.2 kbps async, then port A at the far end must also be configured for 19.2 kbps async. Neglecting to do this may not only result in the inability to pass DTE traffic from end to end, but also misdirect data intended for one port (ex. A) to the opposite port (ex. B) at the far end. This data swapping is a side effect of the rate-swapping feature and only occurs at DTE rates of

Introduction

System Description

Interface

Connection

This chapter describes the screens, menus, and parameters applicable to the DSU MP card that are associated with the PRISM 3060-10 terminal interface, an application program embedded inside those units. Chapter 3 discusses the screens and menus associated with the front panel interface. Although the options are essentially the same for both interfaces, the terminal interface shows more paramet ers on each screen.

The Terminal Interface requires an ANSI-compat ible VT100 terminal (ASCII), or a computer running an ANSI terminal emulation program. The Terminal Interface utilizes ASCII break and escape functions, which are implemented differently by the various terminal emulation programs. The documentation supplied with the terminal emulation program should be consulted for further reference.

In addition to the TR 54016 and T1.403 protocols, proprietary messages can be sent over the facility data link (FDL) from the near-end unit to the far-end unit. A local RS-232 terminal connected to the unit may access a far-end unit. 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.

The terminal may be connected to eith er of two 6 -pin serial RS-232 ports on the unit. One of the m odula r ports is a pair of daisy-ch ain type r ear pane l connector s labele d

A serial bit rate of 1200, 2400, 9600, or 19200 bps may be selected using the front panel control (see Supv Bit Rate on page 33) .

Both serial ports support the same custom protocols which allow the terminal interface or the TXPORT 8100A Site Controller to request and receive performance and configuration data from the unit. The unit automatically determines which protocol is ne eded.

Interface Start-Up On ce a co mpatible terminal is prope rly conn ected to t he unit, a Terminal Interface

session is started by sending a break command or pressing Enter four times to the unit. If the NMS port is used, the unit then responds with the prompt Enter Unit Address. To activate the first (or only) unit, simply press Enter. To select a specific unit, enter the address number of the desired unit and press Enter.

The Enter Unit Address prompt times out after 10 seconds. If this happens, send another break. To select another unit, exit the current Terminal Interface session, send a break, and repeat the process. If an invalid address is entered, that address is echoed back to the terminal. Send another break to start a new session.

The Main Menu screen (Figure 4-2) is then displayed if no password has been specified. The Utilities menu (page 62) explains setting the password. In the

Performance Screens

The Performance screens displa y a detailed history of the error parameters that are continuously monitored. The terminal interface provides display of near- end or far-end performance data using the facility data link.

The unit is equipped with a dual set of performance data registers that hold line statistics for both the telco and user. Each register set provides detailed status and performance history for the network and DTE interfaces.

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

(Performance data) The main body of display data consists of error events for three different

periods: The first display line shows the data accumulated for the current interval (from 0 to 900 seconds). The second line shows the totals for the last 24 - hour period (or the last 96 fifteen-minute intervals). The third line shows the 30 - day totals.

Performance Screens 45

The rem aining lin es of th is screen show the da ta for any in tervals contai ning errors. Interval 1 is the most recently stored 15 - minute interval and interval 96 is the oldest in the current 24- hour period. On the 30 -day screens, interval 30 is the oldest 1 - day interval in the current 30- day period. The real time (or date on 30 -day screens) of the interval beginning is shown in the first column.

If more than five errored intervals have elapsed, Page- Dn appears to the left of the performance data. Pressing Enter on this field displays the next five errored intervals. Page-U p appears once Page-Dn is used. Pressing Enter on Page- Up displays the previous five errored intervals. Only intervals that contained errors are displayed, which eliminates rows of zeroes. If an interval is not displayed, no errors were detected during that time period.

The parameters shown on the Performance screens are updated at five-second intervals.

Per AT&T Technical Reference (TR) 54016, the Standard 24 Hour and Standard 30 Day performance data consists of Errored Seconds (ES), Unavailable Seconds (UAS), Bursty Errored Seconds (BES), Severely Errored Seconds (SES), Loss of Frame Count (LOFC), and Controlled Slip Seconds (CSS).

The Enhanced 24 Hour and Enhanced 30 Day screens show data for CRC Errored Seconds (CRCES), Out of Frame Seconds (OOFS), Loss of Signal Seconds (LOSS), Alarm Indication Signal Seconds (AISS), Remote Alarm Seconds (RAS), and Bipolar Violation Seconds ( BPVS).

For generic TR 54016 far-end devices, only the standard telco 24- hour performance data is displayed. 30 - day data is not available.

Channel Allocation

These lines indicates the network channel assignments with Channel 1 on the left and Channel 24 on the right.

The top line identifies the slot number and the bottom line identifies the port number. A plus (+) sign in the slot position indicates either a remote communication link or the fill channels used for the alternate channel assignment mode. When channels are assigned to a port in the ALTERNATE mode, each data channel is follow ed by an idle channel not assignable for other ports and marked with an X in the port position. Channels may also be assigned as CONTIGUOUS.

The T1 DTE port is identified with an asterisk (*) in the port position. The Remote Comm Link is identified with an R in the port position. Refer to the following example.

Slot 3, DSU 4 is assigned to network channel 16. Slot 3, DSU 5 is assigned to network channel 17. Slot 3, DSU 6 is assigned to network channel 18.

Network channels 19 to 23 are mapped through to the T1 DTE. Network channel 24 is assigned to the remote communication link. Signalling Enabled: shows which channel has robbed-bit signalling enabled.

Signalling Enabled

The signalling option allows selection of Clear Channel or Robbed Bit signalling for each DS0. Each DS0 is set to the Clear Channel DISABLE mode. This setting should not be changed for raw data channels. However, channels using Robbed Bit signalling must be specified to enable proper handling of the signalling bits.

In the Signalling Enabled row at the bottom of the screen, an X indicates that signalling is enabled for that channel.

Port

Par am ete rs

The Port Configuration screen (Figure 4-14) allows viewing and setting configuration parameters for the DSU MP unit.

It is very important that the DTE ports at opposite ends of a link be configured

identically. For example, if port A of one DSU MP is configured for 19.2 kbps async, then port A at the far end must also be configured for 19.2 kbps async. Neglecting to do this may not only result in the inability to pass DTE traffic from end to end, but also misdirect data intended for one por t (ex. A) to the opposite port (ex. B) at the far end. This data swapping is a side effect of the rate-swapping feature and only occurs at DTE rates of 31.2 kbps (in TXP-I mode) and 38.4 kbps (in TXP-II mode) when units are configured improperly.

To send a new configuration to the unit, press Enter on one of the fields or exit the

screen. The underlined values are the factory default parameters stored in ROM.

This screen has the following fields, most of which have user-selectable options. To send a new port configuration to the unit, either press Enter on one of the fields or chang e the Por t #, cha nge the E lement s election, or exit the screen.

ERMINALOPERATION

DDS Mode

The unit can operate in one of four DDS modes on two types of DDS lines.

DDS-I.

DDS-I is a standard mode compliant with industry DDS-I standards allowing the unit to be end - to -end compatible and interoperate with other vendor DDS-compliant DSUs.

DDS-II.

DDS-II is a standard mode that can interoperate with other standard DDS-II

equipment.

TXP-I.

TXP-I is a proprietary mode for DDS-I lines that require a 41TDM or PRISM 3060 -10 DSU MP unit at the other end of the line. This mode allows two-port multiplexing with an in-band data link.

TXP-II .

TXP-II mode is a pr oprietary mode for DDS-II lines tha t require a 41TDM or PRISM 3060 -10 DSU MP unit at the other end of the line. This mode allows two-port multiplexing with an in-band data link.

Port Format

This field show s the data format for the DTE port which can be synchronous (SYNC

) or asynchronous (ASYNC). Asynchronous can be chosen only if one of

the TX P DDS m odes is selected.

Port Mode

The DSU MP interface can operate in either of two modes: NON-TDM

(standard)

and TDM (time division multiplex).

The DDS Mode must be set to either TXP-I or TXP-II to enable the TDM port mode.

NON-TDM (Port 1A, 2A, 3A, 4A, 5A, and 6A).

In the NON-TDM mode, DTE interface B is disabled allowing DTE interface A to run at speeds up to the full usable DDS line bandwidth as shown in Figure 4-15. This option is always available.

TDM (Port 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B, 5A, 5B, 6A, and 6B).

In TDM mode, both DTE inte rfaces are ac tive and are m ultiplexed tog ether in to the sing le DD S network path as show n in Figure 4-16. It allows access to configuration submenus specific to DTE interface B.

Por t Typ e

For ports A and B, the Port Type field displays the installed DTE interface: RS-232C

, V.35, or EIA-530.

For ports B, the interface is RS-232 only.

Tx Clock

Used to select the clock that the unit uses to sample the data transmitted from the DTE. When set to clock that is also supplied to the DTE as Transmit Clock. The

INTERNAL

, the data is sampled directly with the transmit data

EXTERNAL

option

uses the external clock supplied by the DTE.

V.54 Loop

Sele cting Ena ble

allows the unit to respond to in-band V.54 loop commands. If

Disable is selected, the unit ignores these commands.

CTS Control and DSR Control

Setting these fields to FORCE TRUE

or FORCE FALSE (in DSR mode only)

forces the port control lead output state. INTERNAL allows for normal operation.

DCD Control

Setting this fie ld to FORCE TRUE

forces the port control lead output state. INTERNAL allows for normal operation. Far RTS is similar to INTERNAL except that in far-end units the RTS lead becomes an additional qualifier. This selection is only ava ilable when in TXP-I or TXP-II mode. When using Far RTS, ensure that units at both ends are configured for Far RTS. If the unit at the far end is a 41TDM, its RTS parameter must be set to Normal; if it is set to Force On, Far RTS does not work.

RTS Control

Request To Send is an inpu t to the uni t from the DT E. Clear To Send is an outp ut from the un it to the DT E. The behav ior of RTS and CTS is se t as follows. In th e External se tting, the unit rea cts to RTS from the DTE. When RTS is on, the uni t transmits data norm ally and turns CTS on. When RTS is off, the un it transm its idle code to the n etwor k and tu rns C TS off. In th e Forc e True settin g, the u nit ign ores th e state of the RTS lead from the DTE and forces it on internally and forces CTS on.

DDS Status Screen 61

LL Detect

This field allows selecting whether the DSU MP responds to the Local Loop lead on the DTE connector. W hen the DTE device changes the state of this lead, the DSU MP initiates a local loopback. The default setting is disable

RL Detect

This field allows selecting whether the DSU MP responds to the Remote Loop lead on the DTE connector. W hen the DTE device changes the state of this lead, the DSU MP initiates a remote loopback. The default setting is disable

Alarm on DTR Loss

Selecting Enable allows the unit to go into alarm on loss of DTR. The default setting is Disable

ERMINALOPERATION

c = Net Loop

The unit is performing a network loop. On the near end this could be a Line, PLB, ALB (for DDS-I), DSU latching (for DDS-II), V.54 respond, or DT E local (LL p in). If this indicator occurs on the far side in a 41TDM, it is a Line, Local, Data, or V.54 loopback.

d = DTE Loop

The unit is pe rforming a DTE loop. This could be DTE-A, DTE-B, or TDM (DSU MP only).

e = Download Needed

The far end (41TDM ) needs a download.

f = Dial Backup Active

The far end (41TDM) is in dial backup mode.

g = Loop Detected

This occurs only when the unit is in TXP-I or TXP-II mode. The unit detects that it is receiving what it is transmitting so there is a loop somewhere: in the unit, on the line, or on the far end.

Utilities Screen

h = Test Active

The unit is performing a BERT or a far DTE loop test.
