Chapter 1: Introduction andSpecifications

SpectraComm SRM-6 OverviewThe SpectraComm SRM-6 is a six-channel Time-Division Subrate Multiplexer. It multiplexesto six DTEs at the channel interface (RS-232), and connects a SpectraComm V.F28.8/33.6 mSpectraComm 521A/S DDS DSU, SpectraComm 553 T1 DSU, or any RS-232 or RS-530 Ddevice at the aggregate interface in point-to-point applications. A SpectraComm Manager (Scard provides the Telnet and Ethernet connections. Field personnel can attach a VT100/ASterminal to the SCM craft port to provision the SRM-6, monitor alarms and status, and perfodiagnostics and maintenance. The SCM is the SNMP proxy agent for the SRM-6 and the SpeactraComm modem or DSU, allowing alarm traps to be sent to a trap manager.

Intended Use

The SRM-6, the SCM and the companion SpectraComm modem or DSU are each installedsingle slot of the SC5000 high density shelf, or in dual SC2000 shelves linked for managemenSRM-6 front panel LEDs indicate operating status. The mass termination connector at the frpanel connects to an access panel/cable assembly with six DB25F connectors (EIA-232-E interfaces) wired as DCE. This access panel mounts under the SC2000 or SC5000 shelf at tof the Telco rack, or can be attached to the rear of the SC2000 shelf. Refer to Figure 2-2, Figure 2-3 and the accompanying paragraphs for complete front and rear panel connection instruct

Note The SRM-6 can also be connected to a non-SpectraComm DCE device at the aggregate interface. Inapplications, the SRM-6 and the SCM are installed in a single SC2000 shelf. Refer to Chapter 2, Installation and Setup for details.

Features & Benefits

Management Features

The SpectraComm Manager card provides craft, Telnet, and LAN connections for SRM-6 communication, monitoring, and management functions. These functions are accessed via thfront panel EIA-232 craft (CTRL) port, the rear panel DB25F LAN port, and the rear panel RWAN/DBU WAN ports.

Discovery via the SCM

The SCM card performs network discovery of the SRM-6. The discovery function identifies compatible network elements located in the SpectraComm shelf and stores element informaits local database. Information includes the element type, configuration checksum, serial nualarm status, and equipment status. The user can access this information by means of the SManagement Information Base (MIB).

Alarms and Traps

After the initial Discovery, the SCM card polls the active slot addresses for alarms and statisdata on network elements and also polls one inactive slot. By reducing the frequency at whipolls inactive slots, the SCM card can continuously monitor as rapidly as possible and still disnewly installed SCM-compatible equipment. The SCM communicates continually with the SRM-6 and forwards its alarm traps to a designated controller.

Note Refer to the SCM Installation and Operation Manual for additional information on the communicationdiscovery, trap forwarding, and management functions provided for the SRM-6.

Diagnostics

SRM-6 provides an aggregate loopback diagnostic test that can be initiated at the SCM craft via a Telnet connection. This test loops aggregate Transmit Data from the DTEs to Receive Dthe DTEs.

Maintenance

Maintenance features include menu-driven commands for Soft Reset, Load Factory DefaultFirmware Download.

Alarms

SRM-6 Channel Alarms (one for each channel) can be configured as Masked, or Reported.They include:

• No RTS

• No Remote CTS

SRM-6 Aggregate Alarms can be configured as Masked, or Reported. They include:

• No DCD

Timing

In 4-wire, leased private line modem applications that use aggregate data rates of 19.2, 28.8,Kbps, the SRM-6 gets its transmit timing from the SC V.F28.8 modem or one of the DTEs. Omodem is configured for Internal or External transmit timing, with the modem on the other sconfigured for Receive transmit timing. In DDS network applications requiring aggregate dataof 56 and 64 Kbps, the SRM-6 gets its transmit timing from the DSU that is configured for Retransmit timing.

Note For more information on configuring transmit timing in the modem or DSU, refer to the correspondingmanual listed inside the front cover of this document.

SC2000 Dual Shelf Installation

For the SCM card to discover and manage the SRM-6 and the SC modem or SC DSU in thShelf, the following conditions must be in effect:

• In SC2000 Shelf #1: SCM and the SC modem (or SC DSU) must be in slots 1 and

• In SC2000 Shelf #2: SRM-6 must be in slot 3 or 4. Install the blank panel over the empty slot.

• The backplanes of Dual SC2000 shelves must be linked by the management cable SCM to control the SRM-6 and the SC modem (or SC DSU). See Figure 1-1 and Table 2-6 for details.

• A craft connection can be made to any SpectraComm cards via the SCM front panCTRL port.

• Attach the Access Panel at the rear of the SC2000 shelf or to the front of the Telcowith the two SC2000 shelves installed directly above it (Figure 2-2 and Figure 2-3).

• The SRM-6 must be configured for Dual Shelf at its Shelf Configuration screen asdescribed below.

SC2000 Dual Shelf Configuration Procedure

The SRM-6 shelf option factory default setting is Dual Shelf . When installing a field spare ora previously deployed SRM-6 in the Dual Shelf, the last shelf option setting saved to the uninot be known. Perform the following procedure to ensure a match between the SRM-6 shelf setting and the actual shelf type. Note that a mismatch will interfere with SCM managementfunctions. Refer to Figure 2-2 as needed.

1. Temporarily unplug the SC modem or SC DSU from its position in Shelf #1.

2. If the SCM is in Shelf #1 slot 1, plug the SRM-6 in Shelf #2 slot 4. If the SCM is in Shelf #1 slot 2, plug the SRM-6 in Shelf #2 slot 3.

3. Access the SCM terminal interface as described in this chapter under the paragraphs oAccessing the Shelf . From the SCM Main Menu, select Element Access .

4. At the Shelf Inventory screen, select the slot number displayed for the SRM-6 device. Wthe SRM-6 Main Menu appears, select Configuration .

5. At the SRM-6 Configuration menu, select Shelf Configuration , then set the SC2000 shelf type as Dual .

6. At the prompt, type S to save the change to the unit.

7. Plug the SC modem or SC DSU back into its position in Shelf #1.

8. The SRM-6 is now properly configured for the Dual Shelf and can be discovered and main either slot 3 or 4 by the SCM.

9. Verify that the SCM Inventory screen now displays the SRM-6 and the DSU and modem actual slot locations.

Element AddressingThe network management system employs a slot-line-drop method of addressing network ele

• Slot address is the number of the slot it occupies in the SpectraComm Shelf.

• Line address is always 1, and the network element is drop 0. In a point-to-point circuit the single remote unit is drop 1. In a multi-point circuit the drop numbers of the remote units are selectable.

• If the firmware is ever changed on the SRM-6, the nonvolatile memory retains the defined configuration.

• In the SC2000 shelf, the SRM-6 shelf option must be configured to match the shelf(Single or Dual). Otherwise, slot addressing will be compromised and managemenfunctions, including firmware download, will fail. Refer to SC2000 Dual Shelf Configuration Procedure to correct a mismatch condition.

Timing ConsiderationsIn point-to-point TDM operation, Internal or External timing is provided by the co-located modor DTE on one of the two sides. The other modem must be configured for Receive timing.

Note For more information on the setting the timing source at the modem or DSU, refer to the latest issue corresponding manual.

Firmware Download Guidelines

• The Firmware Download function performed at the terminal interface allows you to downnew operating firmware into the unit. New firmware is typically downloaded when GDC releases a new version of firmware that improves performance or adds new features.It is strongly suggested that the user should copy the Active firmware to Standby firmwaprior to downloading new firmware.

• The SRM-6 accommodates Active and Standby firmware. Newly downloaded firmware isstored as the Active Revision. You can switch between Active and Standby firmware as n

• When firmware is changed, the SRM-6 will not need to be reconfigured since the EEPRsaves the configuration.

• In the SC5000 shelf, the SCM allows sequential or broadcast firmware downloads via TFmultiple SRM-6 cards (having the same product code).

• In single or dual SC2000 shelves, ensure that the SRM-6 is optioned correctly for the shwhich it is installed (Single or Dual shelf type), and ensure that SRM-6 and any companSpectraComm cards are in the proper slot locations for the shelf type.

Note The address and product code syntax used in the download process depends on the type of downloa(sequential or broadcast). Refer to Figure 3-2 for a description of download command syntaxes.

Firmware Download Procedures

Sequential or broadcast firmware downloads are performed via Trivial File Transfer Protoco(TFTP). During the download process, be sure to keep the Firmware Download screen on din order to monitor progress and any error messages.

1. At the SRM-6 Firmware Download submenu, select the Download Mode as [2] or [3] .Either of these selections will automatically enable all downloading to the unit.

2. Initiate a TFTP session using the IP of the SCM.

3. At the TFTP prompt, type bin and then press Enter . This causes the transfer to take placin binary mode.

4. Type put [firmware filename] [address & product code] and the press Enter key to initiate the actual transfer.

The [firmware filename] is provided with the firmware that is to be downloaded.The address portion of [address & product code] is the slot/line/drop address when you are downloading to a single unit.

Note Refer to Figure 3-2 for [firmware filename] and [address & product code] formatting.

5. If the Download Mode is [2] Enable Downloads and Store Zipped , the firmware download procedure is complete. The newly downloaded firmware is stored asActive Firmware until you reboot the SRM-6 via a power up/down, or when a soft reset isperformed.

If Download Mode is [3] Enable Downloads, Unzip and Execute , the unit continues with the process of placing the newly downloading firmware into service.
