Configuring the 8K Reference Clock for the GTCS

This describes how to configure the 8 kHz reference clock for the GTCS. Each GTCS extracts the line clock from the A interface and uses the line clock as its reference clock. The GEIUA/GOIUA processes the line clock and generates a 8 kHz clock signal, which is used as the synchronization clock for the GTCS.

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

Prerequisites

The GSCU in the GTCS is configured. For details, see Configuring the GSCU.
The line clock in the GTCS is configured.

Procedure

On the BSC6000 Local Maintenance Terminal, right-click the edge of the GTCS.
Choose Configure 8K Reference Clock from the shortcut menu. A dialog box is displayed, as shown in Figure 1.
