Terminal Interface Overview
GDC SpectraComm modems housed in a SpectraComm shelf support a terminal interface for
monitoring and configuration. The terminal interface is accessed via a SpectraComm Manager
(SCM) card installed in the same shelf with the modem. One SCM card can support interface
functions for up to 15 units in a single shelf or up to 31 units in dual shelf configuration.
