Viewing G350 Sync Sources - Avaya G350 Maintenance Manual

The YELLOW ACT LED on the front of the MM710 Media Module can tell you the synchronization
status of that module.
•
If the YELLOW ACT LED is solidly on or off, it has
source. If it is on, one or more channels is active. If it is an ISDN facility, the D-channel will count
as an active channel and will cause the YELLOW ACT LED to be on.
•
When the MM710 is driving a clock sync source line to the G350 main clock, the YELLOW ACT
LED does not indicate port activity, but instead indicates that the MM710 is the sync source by
flashing with a regular 3-second period:
— It is on for 2.8 seconds and flashes off for 200 milliseconds if it has been specified as a
sync source and is receiving a signal that meets minimum requirements for the interface.
— If it has been specified as a sync source and is not receiving a signal, or is receiving a
signal that does not meet minimum requirements for the interface, then the YELLOW
ACT LED will be off for 2.8 seconds and flash on for 200 milliseconds.

Viewing G350 Sync sources

The following tables illustrate example configurations of the clock synchronization sources:
NOTE:
Unless otherwise indicated, the following commands are sent from the G350 Media
Gateway CLI.
Table 8: G350-001# show sync timing
SOURCE
Primary
Secondary
Local
Comment: No failures, SIG GREEN on and ACT on when trunk is seized
Table 9: G350-001# set sync interface primary v4
G350-001# show sync timing
SOURCE
Primary
Secondary
Local
Comment: No failures, Sig is green and ACT On 2.8s off 0.2s
Note that the MM710 in slot 4 has been declared to be the primary sync source but it is not active
until the next command is sent.
