Adding a GTCS

This describes how to add a GTCS and configure its attributes in BM/TC separated mode through the LMT.

Scenario	BSC initial configuration and BSC capacity expansion
Mandatory/Optional	Mandatory

NOTE:

The number of GTCSs to be configured depends on the traffic volume of the BSC. In BM/TC separated mode, a maximum of four GTCSs can be configured to support 15,360 speech channels (maximum configuration).

A fan box is automatically added when you add a subrack. You need to configure only the attributes of the fan box.

Prerequisites

The cabinet has the space for a new GTCS.
The SS7 OPC is already configured. For details, see Configuring the SS7 Signaling Points.
