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.
