What is a reference manual

Where do I go for information

This manual is a reference guide. It provides information concerning unit configuration, cabling, and testing/troubleshooting on a function-by-function basis. It is not a users guide containing step-by-step procedures. This manual is designed to be used when you need specific information about a command, menu field, port, etc. Unless otherwise noted, the information in this manual applies only to the PRISM 3111/3112 (also referred to as the unit).

The chapters and appendices in this manual are arranged for quick reference when you need it. You do not have to read previous chapters to understand the subsequent chapters. Appendices are designed to complement the main chapters. If you already own TXPORT equipment, you may already be familiar with the appendices.

General - Describes product features and specifications.

Installati on - Describes unit port connections, powering information, and DIP

switch settings. Front Panel Interface - This chapter describes the front panel buttons and LEDs

along with the LCD menu screens and conventions. Terminal Interface - This chapter describes the menu screens and conventions

accessed through the VT100 interface. SNMP Agent - This appendix defines all MIB commands and responses for the

unit. Specifically, this unit recognizes the RFC 1213 and RFC 1406 MIBs. Customer S ervice - This appendix lists all the information needed to contact

TXPORT for sales and marketing information, technical support, and returns.

PRISM 3111

ENERAL

The TXPORT PRISM 3111/3112 CSU/DSU terminates a broad range of T1/FT1 networking applications. The single port 3111 and the dual port 3112 models integrate voice and data, LAN-to-LAN networking, or disaster recovery in either managed or unmanaged environments.

It provides the T1 network connection through an advanced integral ESF CSU. Full performance T1 span monitoring allows early detection and correction of problems before they affect critical applications. The unit provides a wide range of test functions and loopbacks to aid in rapid fault isolation and repair and also responds to inband fractional loop codes to accommodate fractional T1 service testing by the carrier. An internal BERT allows testing of both the network and equipment connections.

The PRISM 3111/3112 is compatible with industry standards ensuring access to any T1 provided service and allowing connection of all equipment quickly and correctly. The unit uses Flash memory allowing firmware upgrades in the field

eliminating the need for taking units out of service for an extended time or returning units to the factory for updates.

When connecting local area bridging or routing devices to a T1 network, other CSU / DSUs are out of the LAN management loop. With the Ethernet or Token Ring management option, the critical T1 connection point is under control of the existing SNMP man agement syste m, providing seam less integration of LAN and WAN, and eliminating the need for a separate CSU / DSU management system.

Channel Assignment

Switch S1-6 selects the channel assignment mode for network T1 DS0s carrying data to the high speed port. Contiguous channel mode (Dn) assigns the channels as a block beginning at channel one for Data Port 1 and the first available channel for Data Port 2, if installed. For example, if the high speed port data rate is to be 256 kbps (as defined by Switch S3), the unit assigns network channels one through four to the high speed port.

Alternate (Up) channel mode assigns an idle channel following each data channel. For example, data are carried on channels 1, 3, 5 and 7. Channels 2, 4, 6 and 8 are idle (the idle setting is binary code 01111111). The advantage of alternate channel assignment is that T1 ones density requirements are maintained by the idle channels rather than placing any restrictions on the high speed data.

Data Port 1

Switch S1-7 sets the multiplier for the Data Port 1 input timing. The unit can operate at any data rate that is a multiple of 56 or 64 kbps. Selecting N x 64K (Dn) provides port bit rates that are multiples of 64 kbps. The ones density requirements of the T1 network line must be ensu red in this mode.

Five front panel LEDs allow a visual identification of the test results and alarms. These LEDs are: NET, BACKUP, TEST, ALARM, and POWER.

NET

This LED il luminates g reen whe n the uni t is in fra me sync. It illumin ates amb er when the unit receives a yellow alarm from the far end. It illuminates red when the unit is out of frame and/or loss of signal.

BACKUP

Amber LED blinks when dialing, connecting, or disconnecting. It illuminates when active.

PRISM 3111

TEST

This LED flashes green when the unit is transmitting loop code. It is green continuously when BERT is on with no errors, when the unit is in a loop condition, or when the unit is in clear test. It is red when the BERT is on and is receiving errors.

ALARM

Red LED illuminates when the unit is in an active alarm condition.

POWER

Green LED illuminates when power is applied to the unit.

22 CHAPTER 3: FRONT PANEL INTERF ACE

Buttons

Two front panel buttons allow you to send loop tests.

TEST

When this button is pushed once, the unit transmits five seconds of in-band loop code out to the network either LLB or V.54 depending on the setting of configuration Switch S2 - 7 (page 18). If S2-7 is set to V.54, this button performs a test on Data Port 1 only. The indicator blinks green during transmission of the loop code.

If configuration Switch S2 - 8 (page 18) is set to Clear Loop, the unit goes into a test mode wher e it will not gene rate alarms.

If Switch S2 - 8 is set to BERT, the test pattern last selected in the terminal interface is tra nsmitted t oward the network. Th e received pattern is compared and if the pattern is received error free, the TEST indicator remains green. If pattern errors are detected, the TEST indicator turns red for one second for each errored second. Therefore, if five errored seconds are received, the indicator will remain red for five seconds.

If the TEST button is pushed again, the unit transmits five seconds of in-band loop down code and returns to normal operating mode. The TEST indicator is then turned off.

LCD Option

LOOP

When this button is pressed once, the unit activates a line loopback, looping the network receive data back to the network (Net LLB). The TEST indicator is illuminated while the unit is in loop. If pressed again, the unit clears the loop and turns off the LOOP indicator.

For additional information concerning test and loop options, refer to page 28.

✍

The LCD front panel interface option (Figure 3-2) allows you to configure network, port, and SNMP parameters and troubleshoot the unit using loop tests and BERTs without having to physically connect a terminal to the unit. The interface screen can be manipulated using the three front panel buttons. The interface screen and the four LED indicators allow you to see the unit’s status.

Timing

Sets the timing source to synchronize the unit’s internal timing generators. Slips are controlled to occur on frame boundaries at the network and / or DSX1 ports when timing synchronization is lost.

Net - Timing is derived from the network recovered clock (most applications use this selection ).

Internal - The unit’s internal frequency standard is used for all timing. Port 1

Timing is synchronized to the external terminal timing clock supplied from

the DTE and connected to the selected port. Verify that the external DTE clock is operating at the data rate se lected for Po rt 1.

T1 DTE - The unit synchronizes the clock recovered from the T1 DTE port.

Rem Comm

This field selects a communication link to the far end unit. You can either assign a DS0 channel (1 through 24) or use an ESF facility data link (0). If ‘0’ is selected, communication is established over the ESF facility data link (valid only when the network interface is configured for ESF and the FDL has end-to-end integrity). For example, the entire T1 bandwidth must be available to the user with no intervening multiplexors in the signal path blocking the FDL.

As an alternative, the communication link may be assigned to an unused idle channel. This option may be used whether the network is operating in D4 or ESF modes.

When the remote communication is programmed to operate over a spare network channel or facility data link, test conditions such as a remote network LLB or PLB or a local network LLB will interrupt access to the far end unit.

These menus establish the necessary parameters for connection with Port 1 and Port 2.

Rate

The unit can operate at any data rate that is a multiple of 56 or 64 kbps. When N x 64K is selected, the ones density requirements of the T1 network line must be ensured. When Nx56K is selected, the unit maintains ones density for the selected DS0 channel.

Ch Asign

Selects whether the channel assignment will be made as a Cont (contiguous) group or as Alt (alte rnate) chan nels. Altern ate channel m ode assigns an idle channe l following each data channel. For example, data is carried on channels 1, 3, 5, and

7. Channels 2, 4, 6, and 8 are idle (the idle setting is binary code 01111111). The advantage of alternate channel assignment is that T1 ones density requirements are maintained by the idle channels ra ther than placi ng any restrictio ns on the high speed data but reduces the available bandwidth from 1.536 kbps to 768 kbps.

Clock

This field is used to select the clock that the unit will use to sample the data transmitted from the DTE. Whe n set to Int (int ernal), the data is automatica lly edge-aligned and sampled directly with the transmit data clock that is also supplied to the DTE as Transmit Clock. The Ext (external) option uses the external clock supplied by DTE. The Oversamp (over sample) option is used to operate the port as a low speed asynchronous port. In this mode, the port rate should be set to at least four times the asynchronous data rate (depending on the degree of allowable distortion for the particular DTE equipment used).

Invert

In the invert mode (Yes), transmit and receive data are inverted at the port interface. This function may be used as a means of guaranteeing ones density when the data is composed of SDLC type protocols. The choices are Yes and No.

Each screen is made up of fields. The two basic field types are user-selectable and display-only. Fields without brackets or parenthesis are display-only. They cannot be changed on the screen.

If the highlighted cursor can be moved to a field, it is a user selectable field. User selectable fields allow for changes to be made or commands to be executed. Most user selectable fields are enclosed in brackets or parentheses.

Main Menu

Fields enclosed in brackets [ ] offer you a list of selections from which to choose. The selections may be toggled by pressing the Spacebar. Each time it is pressed, a new item appears. When the appropriate choice is displayed, press Enter to select it.

There are two methods for manipulating fields enclosed in parentheses ( ). Pressing the Enter key on a field such as (Reset) and (Start Test) immediately executes the function. Typing input when the field is highlighted, such as the Subnet Mask field) ca uses the cu rrent en try to be repl aced with the new characte rs. To edit an existing entry rather than replace it, you need only move the cursor to the point that needs editing. Characters may then be inserted or deleted. Typed data is always inserted rather than typed over. If the field is full, at least one character must be deleted to add another. Many fields of this type may also be toggled by pressing the Spacebar. Other fields are range checked, where you are not allowed to exit with an illegal value s et.

Main Menu

Performance Screen

Element

Target

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 T1 DTE interfaces.

The system has four Performance screens. The STANDARD 24 HOUR and the ENHANCED 24 HOUR screens allow you 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 4-4.

The STANDARD 30 DAY and the ENHANCED 30 DAY screens allow you to view a 30-day history of a particular element’s performance. These screens reference int ervals by date rather tha n by time. To reach eac h of the four scre en types, use the <spacebar> to toggle the STANDARD 24 HOUR field.

Pressing the <spacebar> toggles this field for selection of either the Near or Far unit as the source of performance data or the target of commands. Near refers to the unit to which the terminal is connected. Far refers to the unit at the other end of the network T1 span.

This field selects the display of User or Telco performance registers. Telco registers are for viewing only and may not be changed.

The remaining lines of this scr een show the data for any in tervals containing 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 sc reens) of the inte rval beginning is shown in the first column.

If more than 5 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- UP appears once PAGE- DN is used. Pressing <enter> on PAGE-UP displays the pr evious five errored intervals. Only intervals conta ining errors are disp layed, elimin ating rows of zeroes . If an interval is not dis played, no errors were detected during that time period.

The parameters shown on the Performance screens are updated at approximately

Port Configuration Screen

Channel Allocation

This display- only field indicates the network channel assignments with Channel 1 on the left and Channel 24 on the right. Channels assigned to a port are identified with a port number (1 or 2). Non-assigned idle channels are marked with a dash ( -). Remote communication channels are marked with an ‘R’. When channels are assigned to a port in the ALTERNATE assignment mode, each data channel is followed by an idle channel that is not assignable for other ports and is marked with an ‘ X’. T1 DTE channels are shown with a ‘D’.

Signalling Enabled

An X in this line in dicates that signalling is e nabled for th at channel.

Por t #

Selects the port to be configured, such as One or Two.

Rate Multiplier

The unit can operate at any data rate that is a multiple of 56 or 64 kbps. When N x 64K is selected, the ones density requirements of the T1 network line must be ensured. When N x56K is selected, the unit maintains ones density for the selected DS0 channel.

DS0 Channel Assignment

Selects whether the DTE channel assignment will be made as a Contiguous group or as Alternate channels. Selecting Alternate channel mode assigns an idle channel following each data channel. For example, data carried on channels 1, 3, 5 and 7. Channels 2, 4, 6 and 8 are idle (the idle setting is binary code 01111111). The advantage of alternate channel assignment is that T1 ones density requirements are

maintained by the idle channels ra ther than placi ng any restrictio ns on the high speed data but reduce the available bandwidth from 1.536 kbps to 768 kbps.

Start Channel #

Por t Ra te

Pressing the <spacebar> increases the required port bit rate in increments of 56 or 64 kbps, depending on the Rate Multiplier setting. The Nx multiplier ranges in value from 0 to 24.

# of Channels

This display-only field shows the number of channels to be passed through to the

DTE. The number is determined by the Port Rate value divided by the Rate

Multiplier.

Transmit Clock

This field is used to select the clock that the unit will use to sample the data transmitted fro m the DTE. When se t to Internal, the da ta is automatically edge-aligned and sampled directly with the transmit data clock that is also supplied to the DTE as Transmit Clock. The External option uses the external clock supplied by DTE. The Oversample option is used to operate the port as a low speed asynchronous port. In this mode, the port rate should be set to at least 4 times the asynchronous data rate (depending on the degree of allowable distortion for the particular DTE equipment used).

Dial Backup

Param et ers

The Dial Backup Parameters screen (Figure 4-12) allows you to configure the DBU port.

The Dial Backup functionality supported by the PRISM 3111/3112 allows for an external connection to be made guaranteeing data integrity for Port 1 in the event the T1 NET interface detects certain alarm conditions. The alarm thresholds for the different parameters are sent in the Alarm Configuration menu. The DBU configuration may be set to look for any one or two parameters to go into alarm condition. This is set in the Activator fields. Upon detection of the alarm condition, the unit will at tempt to establi sh a DBU connectio n with the specified parameters.

You can enable the DBU functionality by selecting two of the eight available alarm indicators or by selecting Any. These parameters can be any one of nine errors (LOS, ES, SES, UAS, LOF, RAS, AIS, BPV or Any).

These parameters allow you to establish pre-defined thresholds (set in the Alarm Parameters screen) and initiate dial backup when these thresholds are exceeded. See Alarm Configuration on page 61 to set the threshold parameters.

parameters required for proper operation with an SNMP- based network manager.

Figure 4-14

SNMP Configuration Screen

The 3111/3112 supports alarm reporting by SNMP traps via the LAN or SLIP interface. If the unit’s IP Connection is LAN or Direct SLIP, it expects an IP connection to always be present and outputs its trap messages immediately. If the IP Connection is Dial SLIP, the unit dials out from the modem connected to the SLIP port using the number programmed in the Management Ports screen and outputs trap messages upon connection.

The PRISM 3111/3112 has an embedded SNMP agent supporting MIB-II and the DS1 / E1 MIB. The SET command is supported and has the functionality described below. The 3111/3112 also supports a single telnet session.

SNMP Sets

This field enables or disables the set command responses for SNMP. Refer to Appendix A, SNMP Agent, for detailed information on these responses.

TRAP IP Address

These six rows requ ire numeric entr ies. Each row conta ins four octets. Each of these numbers can range from 0 to 255.

These fields accept the IP address of a network device to which alarm reporting traps are to be sent. The unit detects and reports alarms and provides several options for reporting them, one of which is SNMP traps. When an alarm occurs, the unit sends a trap message to up to six destinations on the user’s network. The trap message is formatted per RFC 1157.

Up to six trap IP addresses can be assigned to report via SNMP. The unit will report each alarm by transmitting an SNMP trap to each trap IP address.

70 CHAPTER 4: TERMINAL INTERFACE

T1 network problems often cause more than one alarm type. In these cases, multiple trap messages are generated, each with a different specific trap type.

The current date may be entered in this field using the MM : DD : YY format. For example, July 4, 1993 is entered as 070493.

Utilities

The time and date for a far-end unit can be set from this screen. However, it will not

✍

be displayed at the top right hand corner of the screen as with the near-end unit.

New Password

This field allows entry of a password of up to 10 characters. An empty string (carriage return only) may be entered to disable the password feature. After <enter> is pressed, the new password is activated and is no longer visible. Therefore, type carefully when entering a new password and verify before pressing <enter>. When the terminal interface is exited and later reactivated, this password must be entered exactly to gain access. If the wrong password is entered, the following message will appear:

Incorrect Password; Please Enter Again.

By using one or more special characters in the VT100 password, the LCD menu is disabled. You may enable the LCD menu by removi ng the special ch aracter(s) from the VT100 password. The special characters are as follows.

!@# $%

^&*()

-=_+;

:,./?

><\ | ‘

~[ ] {}

Do not exit the terminal interface program until the password procedure is fully understood. If a password has been specified, it must be typed exactly to reenter the program.

If you program a password and later forget it, contact TXPORT Technical support for a one-time backdoor password. To get this password, TXPORT must have on file, a letter on comp any letterhead sta ting the names o f the people all owed to access this password. The letter must be signed by an upper-level manager.

The reset operation sets all parameters to the factory default settings and zeros all

✍

performance registers.

Maintenance Reset

This field will clear all user selectable parameters, performance registers, passwords and alarms, but saves the IP Address supervisory port rate and SLIP port rate. All alarm threshold parameters will be reset to default values. The unit reloads sta rt-up configu ration se ttings from the defau lt paramet ers store d in ROM. Pressing <enter> on this field brings up the following warning:

DELETE ALL DATA AND RESTART UNIT? (NO!) (YES)

76 CHAPTER 4: TERMINAL INTERFACE

To exit this screen without performing the reset function, press <enter> with NO selected. To proceed with the reset function, move the cursor to YES and press <enter>.

Factory Reset

Clears all memory including the IP Address and restores the settings to the default parameters stored in ROM.

To exit this screen without performing the reset function, press <enter> with NO selected. To proceed with the reset function, move the cursor to YES and press <enter>.

SNMP A

This unit has an embedded SNMP agent which can be accessed either through the built in SLIP interface or the optional Network Interface Card (NIC). The NIC can be either an Ethernet or Token Ring interface allowing access to the unit through a Telnet or SNMP connection.

SNMP access to the unit is limited to Management Information Bases (MIBs) supported by the embedded SNMP agent. The SNMP agent supports MIB-II (RFC

1213) and the latest DS1 MIB (RFC 1406). This appendix describes in detail how the embedded SNMP agent conforms to the RFCs.
