Global Analog Trunk Module
The Global Analog Trunk Module (GATM) provides an interface for four or eight analog public
switched telephone network lines. This module supports both pulse and tone dialing, as well as
Caller ID and Disconnect Supervision in selected markets throughout the world.
The GATM uses an RJ-21 connector as the trunk interface.
