Querying the Clock Status of a Board

This describes how to query the status of the input clock of a board.

Prerequisites

The LMT runs normally.
The communication between the LMT and the BSC is normal.

Context

Table 1 lists the clock types for different boards.

**Table 1** Boards and their corresponding clocks
Board	Clock
GDPUC/GDPUX/GDPUP	TDM 32.768 MHz clock
GTNU	TDM 32.768 MHz clock
GSCU in the GMPS	Status of the 8 kHz reference clock from the active GGCU Status of the 8 kHz reference clock from the standby GGCU
GSCU in the GEPS	Status of the 8 kHz reference clock from the GGCU
GSCU in the GTCS	0-line back slot 8 kHz reference clock status 1-line back slot 8 kHz reference clock status
GEIUA/GEIUT/GEIUB/GEIUP GOIUA/GOIUT/GOIUB/GOIUP	TDM 32.768 MHz clock
GFGUA/GFGUB/GFGUG GOGUA/GOGUB GEHUB/GEPUG	Low subboard 2 MHz clock Top subboard 0 2 MHz clock Top subboard 1 2 MHz clock Backplane SDH 8 kHz clock Backplane SDH 19 MHz clock Backplane TDM 8 kHz clock Backplane TDM 32 MHz clock Backplane 0 8 kHz clock Backplane 1 8 kHz clock

On the LMT, the clock status of the GXPUM, the GXPUT, and the server cannot be queried. This topic takes querying the clock status of the GTNU as an example. The method for querying the clock status of other boards is the same.

Procedure

Through GUI
1. On the LMT, choose BSC Maintenance > Maintain Device > Query BSC Board Clock State.
2. Set parameters in the Location area, and then click Query. The query result is displayed, as shown in Figure 1.

Through MML
1. Run the DSP BRDCLK command on the Local Maintenance Terminal to query the board clock state.
