136 Chapter 10 Wiring the modules

N0008587 01
The GATM uses an amphenol connector instead of an RJ-type connector, therefore, the wiring for this module differs from the ASM. The cables used by this module should be supplied by qualified technical personnel to ensure the correct pin-out.

To connect the Global analog trunk module (GATM) to the network, follow these steps:

1On the front of the module, locate the amphenol connector.

2Wire one end of the cable to the telco demarcation blocks of the building.

3Wire the other end of the cable to the analog lines.

The following figure and table show the wiring pin outs for a GATM to connect to a service

provider.

* Auxiliary port function: In download mode, the auxiliary port function for all profiles operates as a true Auxiliary port.
This means that when the power comes back on, and if the Aux Port is in-use, that line will show on the system
telephones as being in-use (LCD indicator lit) until the Aux Call is cleared.
In dip switch mode, the North American and Taiwan auxiliary ports also act as true auxiliary ports.
However, the UK and Australia profile auxiliary port function is different. In these profiles, when the power is restored,
the Aux Port call is terminated and the line is available to system telephones.
