Configuring the Line Clock for the GMPS

This describes how to configure the line clock for the GMPS. The GMPS extracts the line clock from the GTCS through the Ater interface. This line clock is used as the input clock for the GGCU in the GMPS.

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

NOTE:

On the GEIUT, up to two line clocks can be configured on the Ater connection paths of the GMPS. A line clock maps an Ater connection path. On the GOIUT, only one line clock can be configured on port 0.

Prerequisites

Preparation

NOTE:

The following procedure takes how to configure two line clock signals on the GEIUT in the GMPS as an example.

Table 1 Example of the data negotiated and planned for configuring the clock on line 0 for the GMPS

Parameter	Example	Source
Line No.	LINE0	BSC internal planning
Line Clock Type	8K	BSC internal planning
Board Slot No.	16	BSC internal planning
Board Port No.	0	BSC internal planning
Backup Port No.	2	BSC internal planning

Table 2 Example of the data negotiated and planned for configuring the clock on line 1 for the GMPS

Parameter	Example	Source
Line No.	LINE1	BSC internal planning
Line Clock Type	8K	BSC internal planning
Board Slot No.	16	BSC internal planning
Board Port No.	1	BSC internal planning
Backup Port No.	3	BSC internal planning

Procedure

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

   NOTE:

   If the Ater connection path where the port of the selected Board Port No. is located incurs a fault, the GMPS cannot extract the line clock from the Ater interface. In this case, the GMPS can extract the line clock from the Ater interface through the Ater connection path where the port of the selected Backup Port No. is located.

   • Board Slot No.: number of the slot where the GEIUT/GOIUT configured with the Ater connection path is located
   • Board Port No.: number of the port connected to one Ater connection path on the GEIUT/GOIUT
   • Backup Port No.: number of the port connected to another Ater connection path on the GEIUT

3. Set the parameters by referring to Table 1.
4. Click Add. The clock on LINE0 for the GMPS is configured.
5. Repeat 1 through 2 to open the configuration dialog box.
6. Select LINE1 and set the parameters by referring to Table 2, as shown in Figure 2.

7. Click Add. The clock on LINE1 for the GMPS is configured.
