SCM Overview

1-6 Verilink SCM

Alarm Relay

The NIM rear panel provides alarm relay outputs. The Form C alarm

relay provides normally open (NO), normally closed (NC), and

common (CO) contacts. The relay is triggered by alarms that may

occur within the node, including the failure of one SCM in a node

with redundant SCMs.

Craft Interface

The SCM Craft interface is a menu-driven ASCII user interface. It is

supported by all modules in the node. It can be accessed locally, or

remotely via Telnet over SLIP or Ethernet.

An SCM installed in each node unifies a network via inband

management. A local SCM can support a terminal session extended

to the remote SCM. The remote SCM in turn, can communicate with

the firmware of the application modules in its node.

Each local SCM can manage one node of one shelf containing up to

13 modules.

Figure 1-4 shows an example QUAD T1 application.
