Explanation
Active An external timing source is being used
as a synchronization reference.
Active The circuit pack is being used as a
synchronization reference.
Steady amber on Active The circuit pack has been reset, but has
not been told which synchronization
reference source to use.
Steady amber off Standby The circuit pack is in standby mode
(neither generating tones nor supplying
clocks).
“Jingle Bells” green and amber
0.1 seconds on, 0.2 seconds off,

Standby The system is running maintenance tests
on the standby Tone-Clock circuit pack.
(The standby circuit pack is providing
tones.)
Other green and amber Active The system is running maintenance tests
on the active Tone-Clock circuit pack.
1. The external synchronization reference being used is a primary reference, or a secondary reference, or an
external Stratum-3 clock when the Tone-Clock is in the master PN. The external synchronization reference
used in a slave PN is an Expansion Interface circuit pack.
