The PRISM 4101 provides the ideal solution for remote DDS branch access to the LAN, video or any other data application. It provides full access to configuration, status, and diagnostic features through either a front panel LCD interface or a software driven terminal interface. The terminal interface is accessable via a SLIP, Ethernet, or Token Ring connection from a wide area network host.

The PRISM 4101 is an advanced CSU/DSU with an embedded SNMP agent and telnet capabilities that can be connected directly to the LAN. The SNMP agent allows the unit to function like any other native LAN element. The agent supports MIB-II and DDS MIBs providing information specific to unit operation. The TCP/IP connection may be accessed through the standard SLIP interface or through the optional Ethernet or Token Ring interface.

The unit provide s a managed inte rface into stand ard DDS serv ice. It supports synchronous data rates from 2.4 to 64 kbps and asynchronous data rates from 2.4 to 57.6 kbps. The rate adaptation feature allows slower rate customer equipment to be transmitted over 56 or 64 kbps lines. The DTE supports both V.35 and RS-232 interfaces. External clocking is supported for use in tail circuit applications.

The PRISM 4101 has diagnostic features allowing quick and easy trouble isolation. The unit responds to all standard loop codes from the telco and can initiate remote V.54 loopbacks. An internal BERT may be used for testing. Line conditions are monitored and reported through the front panel interface, a user connection to the terminal interface, a telnet connection, or through SNMP.

The dial backup feature ensures that critical data applications are secure. The dedicated line service is monitored for trouble conditions. When a line failure is detected, the unit establishes a dial connection through a backup port. Once the backup link is up, the unit routes the customer data through the switched service. When dedicated line service is restored, the unit automatically reverts back. The dial backup port allows you to use any type of external switched service simply by choosing a modem or ISDN unit for dial backup. The PRISM 4101 may also be ordered with an internal 33.6 baud modem.

Before connecting the unit to the LAN, configure the LAN interface using the SNMP Parameters screen (page 1 8 for the front pa nel interface or page 43 for the terminal interface) of the unit firmware. Connection to an IBM Type 1 cable requires a TxPORT adapter kit (9-1001-072-1). This kit includes an impedance matching adapter.

SLIP The SLIP port is an 8-pin modular jack (electrically RS-232) DCE port configured

for 8 bits, no parity, and 1 stop bit. The bit rate defaults to 19200 bps but may be changed through the terminal interface (page 42). Refer to Appendix B, Customer Service for any cabling information. This port is accessible through either a direct connection or a dial-up connection via an AT command set compatible modem.

You can perform network management through the SLIP port as well as the LAN port (page 5) or the SUPV port (page 7). The unit incorporates the full TCP/IP stack, supports inbound telnet, and has an embedded SNMP agent for trap

Dial Connection

In this mode, a modem is connected to the SLIP port allowing you to initiate a SLIP connection to the unit from remote sites whenever access is desired. The modem should be configured to ignore DTR, enable auto answer, inhibit command echo, and return verbose result codes. Also, when the unit has alarm messages to transmit, it dials out of the port using the phone number programmed in the Management Ports screen on page 45. When a connection is made, the unit outputs the ASCII characters stored in its buffer. If a phone number is not programmed, the unit never dials out but you can dial in. The IP connection must be changed to the SLIP port in the TCP/IP screen on page 42. The SLIP and LAN port cannot both be active at the same time. You must use an RS-232 to modem cable connection (9-1001-091-1).

DBU The Dial Backup port is a 10- pin modular connector that either interfaces with an

RS-232 DCE connection on an external device or supplies the connection to the switched network when the internal Dial Backup option is installed. When the port is used with an external device, it can interface to a synchronous or asynchronous device. Configuration of the external device is achieved through AT commands that are configured in the DBU screen of the terminal interface (page 4 6). The interna l Dial Backup option can be ordered as either a 33.6 modem or as an ISDN terminal adapter. Pinout assignments for the DBU port are shown in Table 2-3. Interface cables can also be ordered from TxPORT (page 62).

Power Connection The PRISM 4101 is powered by a 110 VAC captive power supply. There is no

power switch to turn the unit on or off. When power is applied to the unit, the front panel indicators illuminate for approximately five seconds as the unit initializes. The green power LED on the front panel will remain illuminated as long as the unit receives power.

Per UL 1950 and CSA 950 Clause 1.7.2, if the power supply cord is intended to

✍

serve as a disconnect device, a socket must be installed near the equipment and be easily acce ssible.

Pow er Fa il ur e If the indicator does not illuminate, recheck the power connections. For AC

powered units, check the primary AC circuit breaker.

The PRISM 4101 provides non-volatile memory retention of the unit configuration in case of a power failu re. This feature allows the unit to aut omatically re store normal service following a power loss.

Data Mode

The unit can operate in two general modes. The DDS standard mode STANDARD

provides complete compliance with industry DDS-I standards, allowing the units to be end - to -end compatible and interoperate with other vendors DDS compli ant DSUs. For a wider variety of applications, the unit can operate in the TxPORT proprietary mode. In this mode, TxPORT equipment must be located on both ends.

The DDS stan dard operati ng mode match es the DTE rate to the line rate. I n this mode, the DTE interface operates synchronously at the selected line rate. These selections are shown as STD in Table 3-1.

The TxPORT proprietary mode is used to support asynchronous DTE data, rate adaptation of subrate DTE data onto 56 or 64 kbps lines, and provide an end-to-end communications channel between DDS units. The specific DTE data/loop rate combinations are shown as TXP in Table 3-1.

Timing

The PRISM 4101 can source its timing from three choices. With NETWORK selected, timing is derived from the network recovered clock (the normal DDS mode). With DTE selected, the unit synchronizes to the clock recovered from the DTE port (DTE clocking is supported only in Standard mode). With INTERNAL selected, the internal oscillator’s frequency standard is used for all timing.

Alarm Thresholds

The unit can be pr ogrammed to generate an alarm condition based on a specific level of performance degradation. Alarm thresholds are set for periods of 1, 2, 3, 4, 5, 10, 20, and 30 consecutive seconds for the OOS, OOF, and LOS parameters. A field set to [--- ] causes t he unit not t o alarm o n that stat istic. To effectively disable alarm reporting, set all fields to [-- -].

OOS - Sets th e Out of Ser vice second s thresho ld. This oc curs when the OOS co de is received from the DDS network. The default value is disabled [---].

LOS - Sets the loss of signal seconds threshold. The default value is 5

OOF - Sets the Out of Frame seconds threshold. This occurs on receipt of OOF code from the DDS network. The default value is disabled [- - -].

ART - Sets the alarm reset timer. The setting determines when the Alarm Indication/Contacts are cleared after the last error. The choices are 0, 10, 20, 30

60, 90, 100, 200, 300, 400, 500, 600, 700, 800, and 900 seconds.

Mode

The unit can operate in two general modes (sync and async). When a unit is configured for asynchronous DTE data, it operates in the TxPORT proprietary mode and requires another PRISM 4101 on the remote end. The supported asynchronous DTE rates are listed in Table 3-1. The following parameters must be set for asynchronous operation; the number of async bits per character is 8, the number of stop bits is 2, and parity is none.

This display-only field sh ows which ele ctric al interfa ce is ac tive (either the V.35 o r the RS-232).

Antistreaming Timer

This timer is used to prevent a streaming DTE, on a tributary DSU in a multi-point circuit, from locking up the circuit. If the RTS lead from the DTE stays constantly active for the anti-streaming time, the unit shuts off data transmission into the network. When ever RTS go es inactive, the anti-s treaming tim er is reset. Th e timer can be turned Off

or set for 10, 30, or 60 seconds.

unit condition.

RTS

Request To Send is an input to the unit from the DTE. Clear To Send is an output from the unit to the DTE. The behavior of RTS and CTS is set as follows. In the Normal setting, the unit reacts to RTS from the DTE. When RTS is On, the unit transmits data norm ally and turns CTS On (depending on the setting of Circui t Assurance an d after the dela y set by the RTS/CTS Delay option). When RTS is Off, the unit transm its idle code to the network and tu rns CTS Off. In the Forc ed On setting, the unit ignores the state of the RTS lead from the DTE and forces it On internally and forces CTS O n.

Circuit Assurance

This option allows the CTS control lead to respond to the data signal from the network. With Enabled se lected, the unit will turn Off the CTS le ad when receiving idle code (for example, if DCD is Off). With Disabled

selected, the state

of the CTS control lead is not affected by data signal from the network.

SNMP Configuration The SNMP (Simple Network Management Protocol) interface is a feature of the

unit which provides seamless integration and control of CSU / DSU functions within an existing SNMP managed LAN/ WAN environment. SNMP management stations are able to collect and analyze data from all network devices which comply with the SNMP protocol and to manage those devices.

SNMP provides a standard means to moni tor the status of all compatible network elements. The PRISM 4101 management capabilities are expanded by the inclusion of the TxPORT MIB and the enterprise DDS MIB. Objects in these MIBs, and MIB loading instructions are listed in Appendix A.

The SNMP Configuration screens are used to configure the Ethernet, SLIP, or Token Ring SNMP interfaces. It allows for the entry of those parameters required for proper operation of the unit with an Ethernet, SLIP, or Token Ring based LAN manager.

Dial Back Up

The unit offers two methods of providing an alternate data path in cases where the DDS network connection fails. These are an internal 33.6 modem or an external device, synchronous or asynchronous, which is compatible with a switched circuit technology. The 10-pin modular DBU port provides the access for either method.

Command. The choices are ENABLE, DIS ABLE, DAILY, and ACTIVATE.

DISABLE - Does not allow the unit to respond to a dial backup situation. ENABLE - Allow the unit to respond to a dial backup situation. DAILY - Allows the unit to respond to a dial backup situation only during the

specified time period fo r that d ay. Selecting this opt ion causes the Dail y Periods configuration field to be activated at the end of the Scroll menu. See Daily Periods on page 25 for configuration information.

ACTIVATE - Forces the unit to place a call and switch to the dial backup device.

DBU Activator. Used to select the crit eria that the u nit will use to ac tivate the dial

backup sequ ence. The cho ices for the D ial Backup U nit Activator are LOS

, OOS,

OOF, and ANY Alarm Thresholds.

Format. Sync or Async, depending on DBU device capabilities. DBU device

configuration and dialing is always Async.

DBU Rate. Used to select a dial backup rate of 2.4, 4.8, 9.6, 19.2, 38.4, or 57.6

kbps. The applicable rates depend on the type of modem used or whether a terminal adapter is used. If DBU format is Sync, this field only applies during the configuration and dialout process.

Cursor 29

Cursor

The terminal interface uses a h ighlighted cursor to make se lections fr om menus and select fields within screens. The cursor is moved in different ways, depending on the terminal emulation program used. Most programs use the Tab and Shift+Tab keys. Other programs use the arrow keys. For keyboards which do not have these standard keys or have only some of them, an alternate set of cursor control commands is provided. Each command is performed by pressing a lett er key while holding down the Control key. Alternate commands may be freely mixed with the keyboard commands at your discretion.

Field Types

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.

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 Return to select it.

There are two methods for manipulating fields enclosed in parentheses ( ). Pressing the Return 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 causes the curr ent entry to be rep laced with the new characters. 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 in serted rath er than typed over. If the field is full, th ough, 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 set.

Bidirectional Loop

NET

There are four loop types that can be activated from the PRISM 4101. They are line loop, data loop, V.54 loop, and local loop.

Line Loop. Occurs at the D DS network interface and is activated by the reversal of

the simplex, 20 mA sealing current. This is a unidirectional loop that ignores the unit transmi t data and retr ansmits the re ceived DDS data. Rece ive data is unaffected and circuits DSR and CD are optionally forced Off.

Line Lo op

Data Loop. Occurs at the data port (DTE) interface and is activated when the unit

DTE

NET

receives alternating loop codes in the network receive data stream. Technically, it is activated by the receipt of at least four consecutive loop commands and remains looped as long as each third pattern byte is the loop command. It returns to normal operation after at least four pattern bytes that are not the loop command. This is a unidirectional loop that retransmits the PRISM 4101 received data on the unit transmit data including the remapped loop code. Receive data is unaffected (but includes the modified loop codes) and circuits DSR and CD are Off.

Data Loop

V.54 Loop

V.54 Loop. Occurs at the DTE data port interface and is activated upon receipt of

DTE

NET

inband V.54 loop codes for at least two seconds followed by all ones in the network receive data stream. This loop is unidirectional and retransmits the PRISM 4101 received data on the unit transmit data including the remapped loop code. Receive data is unaffected (but includes the modified loop codes) and circuits DSR

and DCD are Off. You may instruct the unit to transmit inband V.54 loop code to the remote end unit causing it to enter a V.54 loop.

The PRISM 4101 can not transmit alternating DSU loop code or cause sealing current reversal to activate a loop on the remote end unit.

Local Loop.

This loop occurs at the DDS network interface as a bidirectional loop. It returns the DDS receive data to the DDS transmit line and the PRISM 4101 transmit data to the unit rece ive data output.

Local Loop

In TxPORT mode, local loop functions differently. It is always a unidirectional loop, implemented at the DTE interface. This allows the end-to-end data link to remain

operational during the loop.

interoperate with equipment from another vendor.

Main Menu 37

Timing. The unit can source its timing from three choices. NET uses the network

recovere d clock (the normal DDS mode). DTE uses the clock recovered from the DTE port and is allowed only when the Data Mode is set to Standard. INT uses the internal os cillator (25 ppm) for all tim ing.

Circuit Assurance. Allows the CTS control lead to respond to the data signal from

the networ k.

If On is selec ted, the un it will turn Off the CTS lead wh en receiving idl e code (for example, if DCD is Off). If Off

is selected, the state of the CTS control lead is not

affected by data signal from the network.

When Circuit A ssurance is se t to Off, CTS follows RTS. When RTS transitions to the On stat e, CTS will t ransi tion to the O n state after the RTS/CTS delay. CTS will transition to the Off stat e within o ne bit tim e when RTS transiti ons to the Off state.

When Circuit A ssurance is se t to On, CTS follows RTS if DCD is On. Wh en RTS transition s to the On state , CTS will trans ition to the On s tate after the RTS/CTS delay if DCD is O n. CTS will tran sition to the Off state when RTS transitions to the Off state. CTS is Off if DCD is Off.

RTS should be set to Normal on the DTE PORT parameters w hen Circuit Assurance is On. The Force DCD option will be changed to N ormal.

Anti streaming Timer. The Antistreaming Timer is used to prevent a streaming DTE

on a tributary DSU, in a multi-poi nt circuit, fro m locking up the circuit. It is controlled by RTS. If RTS remains enabled long enough for a timeout to occur, the unit will drop CTS and stop sending DTE data. The Antistreaming Timer is reset when RTS transitions to the Off state. Choices are Off

, 10, 30, and 60 seconds.

DTE Port Parameters

When operating in the proprietary mode, an end-to-end management link is established between units. Remote communications between units operates on a sideband channel and is not disruptive to the customer’s data traffic. On a 56K loop, the maximum DTE rate is 54 K sync (57.6 K async) and on a 64K loop, the maximum DTE rate is 62K. At line rates less than 56 kbps, only async format is

The unit supports alarm reporting by SNMP Traps when running the LAN or SLIP interface. If the unit’s IP connection is LAN or DIRECT SLIP, it expects the connection to always be present and thus 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 modem connection.

The PRISM 4101 management capabilities are expanded by the inclusion of the TxPORT MIB and the ent erprise DDS MIB. Objects in these MIBs ar e listed in Appendix A. The unit also supports a single telnet session.

Generic MIB Loading Instructions

DDS Network Objects

The MIBs were written using the standard ASN.1 notation. Any standard SNMP manager should be able to compile the MIBs. Although the exact procedure for loading MIBs may vary from one platform to another, the following basic steps are the same.

1 The SNMP manager has a directory for MIBs. Copy the files DDS.MIB and

TXPORT.MIB into th is directory. The MIBs are sen t out on a DOS-fo rmatted diskette, therefore, a DO S2UNIX command may have to be used for UNIX workstations (typical directories are snmp_m ibs for OpenView Manager, and mibfiles for Castle Rock SNMPc

2 Start the SNMP manager if it is not already running. Select one of the menu

selections (or selection subheadings) that contains the SNMP MIB operations (this is Options subheading for HP OpenView and Config subheading for SNMPc).

3 Choose the option for LOADING or COMPILING MIBs. You must specify which

MIBs to load. If the manager only allows one MIB to be loaded at a time, load the file TXPORT.MIB b efore loa ding the D DS.MIB.

4 Once the manager has successfully loaded the MIBs, you are ready to manage the

TxPORT products. If you have any questions please call TxPORT Product Support.

Definition of Traps 57

Definition of Traps

TxPORT products with SNMP support provide for the detection and reporting of network alarms. When an alarm occurs, the SNMP agent sends a trap message (formatted per RFC 1157) to multiple destinations on the user’s network. The generic trap type is enterpriseSpecific (generic-trap = 7).

Network problems often cause more than one alarm type. In this case, multiple trap message s are genera ted, each with a different specific-tra p type.

Some alarm types do not apply to cer tain products.

✍

The Trap-PDU has six mandatory fields as shown in the lower level of Figure A-1.

PDU Tag PDU Length PDU Field Value

Enterprise Time StampGeneric Trap #Agent Address VarBindListSpecific Trap #

Figure A-1

The Enterpri se field is compos ed of the Objec t Identifier of the MIB branch containing the trap definitions. Returns { 1.3.6.1.4.1.425.4 } { txport traps }.

Trap-PDU Format

enterprise Specific Traps

The Agent Address Field is the agent’s IP address unit. This further identifies the trap sender to the NMS receiving the trap.

The Generic Trap field contains an integer value that represents one of the standard predefined traps fo r SNMP.

The Specific Trap field contains trap values defined for a particular enterprise. The values in this field are de fined in the TXPO RT.MIB and the fol lowing tables. The list is broken down in specific sections to group trap definitions by use.

The Time Stamp field contains the time the trap was generated in the form of time ticks that have elapsed s ince the agent was initialize d. The value is in un its of hundredths of a second. ifIndex is typically provided in the Variable Binding List.

The Variable Bindings List contains supplemental implementation information when includ ed in the Trap-PDU.
