6 Message Reference

Description:

This message is issued by the board to indicate events within the on-board

clocking circuitry.

Parameter Description:

Event ID

This field specifies the event that caused the indication to be generated:

event_id Description

PLL entered hold-over mode

Issued by boards acting as primary or secondary clock master when its

nominated clock reference becomes unavailable. The phase-locked-loop

starts operating in “hold-over” mode, continuing to generate an on-board

clock at the same frequency as the last valid reference signal.

PLL left hold-over mode

The nominated clock reference for a primary or secondary master board has

become available and the is now being used as the input to the board’s clock

circuitry.

CT bus clock set A fail

The CT bus clock set A signals are not being correctly driven.

CT bus clock set A recover

The CT bus clock set A signals are being driven.

5 CT bus clock set B fail

The CT bus clock set B signals are not being correctly driven.

CT bus clock set B recover

The CT bus clock set B signals are being driven.

Master clock changeover

The board issuing this indication has automatically changed from secondary

master to primary master role for the clock set it was configured to drive.
