Theory of Operation

The SC-M13 device occupies four adjacent slots in a 19-inch SpectraComm 5000 shelf. The consists of one dual-width MUX termination unit (MTU) and one or two MUX controller units(MCUs). The MUX controller unit (MCU) is installed singly, or as an Active and Redundant (standby) pair. For non-redundant applications, a filler panel should be used in the empty foslot.

Card Functions

The MTU has a dual-width front panel which has two female 64-pin Amp-type telco connecto28 DSX-1 connections and two pairs of female BNC connectors for DS3 connections. The Minserted into the shelf and fastened to the shelf by two captive screws on the front panel.

The MCU is a single-width card that is installed via a latching tab on the front panel. Each hswappable MCU contains all of the active components for multiplexing 28 DSX-1s into one

Redundancy Functions

To provide hardware redundancy, the SC-M13 device uses a 1 + 1 scheme, meaning that thone active MCU plus one redundant (standby) MCU. When the active MCU fails, automaticswitchover to the redundant MCU will occur with minimal service interruption.

The SC-M13 device also provides line redundancy in the event that the working DS3 line faWhen one MCU is available the user can manually switch over to the other line. When two Mare available, the switch is made automatically.

Note For detailed information on the theory and operation of hardware redundancy and line redundancy, recorresponding sections in Chapter 4.

Connectivity & Interfaces

MTU Card (Occupies Two Adjacent Slots)

• Two front panel female 64-pin AMP-type telco connectors (TX and RX) support DSX-1 sigwith industry defined pin-outs.

• Two pairs of front panel female BNC connectors support two DS3 signals. The second pair provides line redundancy.

• The rear panel RJ-45 connectors are used to send audible office alarms and to daisy chain audible office alarms.

MCU Card (Single or Redundant)

• Front panel RJ-45 connector provides an EIA-232 VT100 Craft connection via a serial EIAport, Comm - 9600 bps, 8 data bits, No parity, 1 stop bit.

• The Rear panel RJ-45 connector provides 10/100 BaseT Ethernet connectivity for SNMaccess and Telnet management. This auto-negotiating Ethernet port with MDIX can autopairs, if required.

Note For detailed connection and pinout information, refer to Chapter 2: Installation and Set-Up.

Management

The SC-M13 device can be monitored and managed locally via the password-protected crainterface, or via a secure Telnet connection from the central site or other remote sites.

Craft/Telnet Management

The SC-M13 employs an interactive command line interface (CLI) that will feel familiar to mfield personnel. Added features include auto-prompting for command arguments, recognitioabbreviated commands, online help, command line recall and an advanced utility for generadownloadable ASCII configuration files. The CLI is accessed through a craft port connection front panel, or through a Telnet connection at the rear panel ethernet port.

SNMP Support

The SC-M13 has an embedded SNMP agent and supports SNMP MIB-2 (RFC 1213). Maskable SNMP traps include Protection Switching, Standby Failure, and T1 alarms and T3alarms. The Authentication Failure and Cold Start SNMP traps cannot be masked by the us

Note SNMP support does not require a SpectraComm Manager (SCM) card co-located in the shelf.

TEAM/SCM Management

The SC-M13 is auto-discoverable in a SpectraComm shelf when a SpectraComm Manager(SCM) card is present. In TEAM applications, SC-M13 will be recognized by TEAM (Total Enterprise Access Management) software applications which use HPOV APIs (Application Programmer Interfaces) to integrate with HP OpenView Windows and other network manageapplications.

TEAM displays the SC-M13 front-panels (MCU and MTU cards) in the corresponding slots. Openview auto-discovers the IP addresses of the SC-M13 and allows a launch of Telnet to M13 command line interface from the Openview IP network map. For more information on tTEAM features, refer to the TEAM Core Operation Manual on your Technical Publications C

Note TEAM support requires an SCM card co-located in the shelf with the SC-M13. For more information,to the GDC TEAM Core documentation and Release Notes and the SCM Installation Operation Man

Diagnostics

SC-M13 diagnostics can be initiated by the network manager via a craft or Telnet connectionthe network, as shown in the table below.

Alarm Reporting & Performance Monitoring

In addition to displaying alarm status, the Active MCU will report alarms as SNMP traps and ocontact closures. For the network (DS3) interface alarms, the following alarms are reported:of Signal, Out of Frame and Alarm Indication Signal. For the DSX-1 interface alarms, the folloalarms are reported: Loss of Signal, Alarm Indication Signal-Carrier, and Alarm Indication SiDrop.The following additional alarms are also reported: Authentication Failure, Cold Start anStandby Failure.

The SC-M13 accumulates the following Performance Monitoring (PMON) statistics for the Dinterface: Errored Seconds, Severely Errored Seconds, and Unavailable Seconds. For the Dinterface, Severely Errored Seconds and Unavailable Seconds are accumulated.

Note The Standby MCU will only report Cold Start alarms and Authentication Failure alarms.

Transmit Timing

For DS3 timing, the SC-M13 provides selectable Network Timing (recovered from the DS3 resignal) or Internal timing (on-board Stratum 4E clock). Each of the 28 DSX-1 connections declocking from either end of the T1 connection. Thus, independently clocked T1 service connecan be carried in the same DS3 line.

Chapter 2: Installation & Connections

Installation OverviewThis chapter describes installation and setup procedures for the SpectraComm M13 device(redundant or non-redundant). Installation and setup procedures for both devices are the saexcept where noted. This chapter describes installing the SC-M13 device cards, making poconnections, performing pre-operational checks, and making system connections. If this is yfirst installation of the SC-M13 device, be sure to read the previous sections of this manual understand the optimal functioning of the device as it applies to your network.

Shelf / Enclosure Installation Guidelines

• Locate the SpectraComm shelf in a ventilated area where the ambient temperature doeexceed the environmental specifications (Table 1-2).

• Do not install the shelf directly above equipment such as power supplies, which generateamounts of heat.

SpectraComm M13 Installation Guidelines

• The SC-M13 with redundancy has two MCUs; the non-redundant SC-M13 has one MCU

• The SC-M13 device may be installed in any four consecutive slots of a SpectraComm 5Shelf or MultiPak. Whenever device cards are removed and plugged back into the shelffollow the device installation procedure in this chapter to avoid damaging connector pins

• As a general rule, whenever you need to reset the unit, use the command line interface execute the reboot command, rather than unplugging the MCU card from the backplaneconnector.

• Perform the setups, connections, and pre-operation checks in their entirety, as describedchapter. Then configure the device as described in Chapter 3, SC-M13 Configuration

• In redundant systems (with two MCU cards), unit configuration is shared between both MTherefore, when changing unit configuration on one MCU, always provide enough time (afive seconds) for the new configuration to automatically download to the other MCU. Doremove or reset either MCU card before this interval.

Installing the Unit in the Shelf

1. Slide the MUX termination unit (MTU without the MCU cards attached) into the SC5000shelf, easing the assembly into the backplane connectors.

2. When the MTU is firmly seated in position, tighten the two captive screws on the front pa

3. With the GDC logo on top, slide the MUX controller unit (MCU) part-way into the slot on left of the termination card.

4. Before the MCU card’s 60-pin connector makes contact with the MTU receptacle, visuaalign the connector’s four tabs with the receptacle’s four slots. Then, ease the card firmlythe receptacle. This will ensure no damage occurs to the connector pins.

5. Pull down the insertion/extraction tab on the front panel of the MCU and firmly push the in until it seats firmly in the MTU receptacle.

6. For redundant applications, install the second MCU in the same manner, using the slot right of the MTU; for non-redundant applications, install a filler panel instead.

Note IMPORTANT! In redundant systems, do not remove or reset either MCU card during or immediately aconfiguration change. Allow five seconds for the MCU to download the new settings to the other MCU

Power-Up and Self Test

Before making connections, determine whether the SC-M13 device can be powered from theAC circuit as the equipment connected to its craft port. Having the SC-M13 device and the connecting equipment on the same AC circuit prevents large circulating currents caused bydifferences in ground potential.

Power-On Self-Test

The SC-M13 executes a Power-On Self-Test (POST) every time it powers up or at every resePOST will test the operation of the microprocessor, flash, RAM, etc. The front panel ON LEDilluminate to show that power is available to the unit. With a successful power-up, either theONLINE or STNBY front panel LED will illuminate to indicate that the M13 is operating correc

Shelf and Card ConnectionsThe following paragraphs describe cables, connectors, and pinouts for each front or rear conwhen the SC-M13 is installed in GDC shelves and enclosures (Figure 2-1). When making card and shelf connections:

• Always adhere to the installation guidelines, cited in the beginning of this chapter, and thconnection guidelines listed below:

• Observe all ESD precautions during installation procedures. Be sure to wear a properly grounded antistatic wrist strap.

• Make all electrical connections through the back panel and front panel connectors provi

Note If you cannot determine whether both devices are on the same circuit, verify that the potential differbetween the grounding circuits of the respective power outlets is no more than 0.25V rms.

Note The AC outlet that powers the SC-M13 units should not be under switch control.

Chapter 3: SC-M13 Configuration

Configuration Overview

SC-M13 configuration is performed through the command line interface (CLI). You can execCLI commands at a HyperTerminal connection using a VT100-compatible ASCII terminal connected to the SC-M13 craft port. The CLI can also be accessed through a Telnet connectiCLI is a smart, controlled-access interface that provides general and context-sensitive help,automatically expands abbreviated command or subcommands and also anticipates any recommand arguments. The CLI will prompt for any required argument that is missing from a command line. A brief overview of CLI is provided below.

Note For a detailed guide to Smart CLI, refer to Appendix A, Application Guidelines

Smart CLI Quick Reference

Note For online help screens describing all CLI options, press ? Note that the CLI options for configuring theSC-M13 are only available when you have enabled Supervisor or Admin privileges.

6. Enable supervisor privileges by typing enable . When prompted for the password, type:

supervisor [default supervisor password]

7. The SC-M13 is now operating in supervisor mode as shown by the # symbol in the new CLI prompt, with most CLI options available (Admin mode permits additional CLI commands

8. You can now configure the SC-M13 to suit your network by typing the required configuratcommands at the CLI prompt. You do not need to set parameters that coincide with systdefaults. Any configuration changes will take affect immediately.

Note FOR ADVANCED USERS: The SC-M13 provides a utility for generating the configuration settings inASCII file, simplifying the configuration of multiple SC-M13 devices. This function can also be used tarchive configuration data for specific unit or as a baseline for modified configurations.Refer to Appendix A, Application Guidelines : Maintenance Guidelines .

Setting Up User Accounts

The following paragraphs describe the basic procedures for accessing and configuring SC-Musing the command line interface (CLI). Access to the SC-M13 is controlled by three CLI acmodes: USER, SUPERVISOR and ADMIN. The password-protected enable command sets the access from user mode to supervisor or admin mode, depending on the password entered. command prompt suffix character identifies the mode you are currently in:

• For USER mode, the prompt string ends in >Commands in USER mode allow viewing but not changing configuration data.

• For SUPERVISOR mode, the prompt string ends in #Commands in SUPERVISOR mode allow USER access plus the ability to change configuration data, reboot the unit, manipulate flash files and enable the TFTP server fodownloads.

• For ADMIN mode, the prompt string ends in %Commands in ADMIN mode allow SUPERVISOR access plus the ability to set up and mouser accounts for usernames and passwords. ADMIN mode also allows authentication f CRAFT port to be turned on or off.

Note Up to 20 usernames/passwords may be specified. The Default Username is gdc ; In User mode, the Default Password is gdc ; Supervisor mode password is supervisor ; Admin mode password is admin .

User Accounts Procedure

1. Type disable to turn off supervisor/admin access.

2. Turn Admin mode on by typing enable and entering the admin password. The commandprompt will now contain the % character.

3. Modify default admin and supervisor accounts and delete default accounts by typing:

configure accounts add admin [new admin password]configure accounts add supervisor [new suprv password]configure accounts delete gdcconfigure accounts delete supervisorconfigure accounts delete admin

4. Add a user account and password by typing:

configure accounts add [name] [password]

5. If desired, enable craft port authentication by typing:

configure accounts console enable

Note IMPORTANT! For a higher degree of security, it is strongly recommended that default usernames/passbe changed to some other unique textstring.

Special Considerations

• The Telnet login password cannot be changed via a Telnet connection; it can only be chby an Administrator at the Craft port. See Chapter 3, SC-M13 Configuration .

• Concurrent management sessions at the same SC-M13 are not allowed on the same in(craft or Telnet). In redundant systems, however, two concurrent management sessionsallowed (one to each MCU). In such situations, the last saved configuration will take effeboth MCUs. See SC-M13 Hardware Redundancy in this chapter for more information.

• Telnet access is enabled at the SC-M13 as a default. If desired, Telnet access can be dbut can only be enabled again by a Supervisor or Administrator at the craft port.

SC-M13 Hardware Redundancy The SC-M13 provides Hardware Redundancy that employs automatic protection switching tStandby MCU card in the event of hardware failure of the Active MCU. Hardware Redundanavailable when two properly configured MCU cards are installed and communicating via theInterComm bus (ICB). When the ICB is active, the screen prompt prefix is a plus (+) sign. When there is no other MCU detected or when the ICB is down, the prefix is a minus (- ) sign.

The Active MCU card constantly monitors its own hardware for proper operation and also communicates to the other MCU via the ICB. The Standby MCU mirrors the Active MCU configuration so that both cards are receiving the same data and framing on the DS3 and Dnetworks; this ensures the most rapid transition in the event of a hardware failure.

Figure 4-1 Hardware Redundancy Help Display

Configuring Hardware Redundancy

1. Before configuring the SC-M13 for Hardware Redundancy, be sure the device is otherwconfigured as described in Chapter 3, SC-M13 Configuration .

2. The MCU cards are shipped from the factory in Standby mode. Configure one card as thActive MCU by typing:

configure mode operating-mode [active]

3. To verify both MCU cards are functional and capable of redundancy, type:

show redundancy

Figure 4-2 Redundancy Status Display

Hardware Switching Sequence

If there is a hardware failure at the Active MCU, an automatic hardware switch occurs in thefollowing rapid sequence:

• Standby MCU enters Active mode and forces the formerly Active MCU to Standby

• Hardware Redundancy is disabled on the formerly Active MCU.

• The new Active MCU takes over data-passing functions on DS3 and DSX-1 netwo

• The new Active MCU sends an SNMP trap of the hardware switch event.

Note Once Hardware Redundancy is enabled at the Active or Standby MCU, it can only be disabled at the S

Restoring Hardware Redundancy

1. Determine the cause of the switch and determine whether the formerly Active MCU is stoperational. Do not re-install or enable redundancy in a failed MCU unless it is certain thMCU is fully operational.

2. Reinstall the MCU or replace an inoperable MCU with a field spare. The reinstalled or replaced MCU is now the Standby MCU with hardware redundancy already enabled.

If you can confirm operability of the failed MCU without unplugging it from the shelf, re-enabled hardware redundancy (it is now the Standby MCU) by typing:

redundancy hardware enable

3. The Active MCU will immediately download the proper configurations to the newly enabStandby MCU and hardware redundancy will be in effect.

Note IMPORTANT! When changing the configuration of an MCU, always allow five seconds for the unit todownload the new settings to the other MCU. Do not remove or reset either MCU card before this int
