New hardware
This section describes the new hardware that was released in conjunction with the BCM 3.5 software
release.
This includes:
• Global Analog Trunk Module (GATM) on page 16
• Auxiliary equipment on page 21
Global Analog Trunk Module (GATM)
The following table demonstrates who the GATM fits into the Business Communications Manager trunk
module suite.
The Global Analog Trunk Module (GATM) provides an interface to the telephone company analog lines
for the Business Communication Manager. The module supports both pulse and tone dialing, Caller ID,
and Supervision Disconnect in various markets.
UK profile configuration note: The GATM does not support Earth Calling even though the option appears
in the Unified Manager Lines record. Only a FEM connected to a Norstar analog trunk module supports
this feature.
