Maintaining Clock Synchronization
Procedure
- Run system-view
The system view is displayed.
- Configure the function of maintaining clock synchronization as required.
Run the clock alarm-switch ais enable command to enable the AIS alarm of the E1 interface to associate with clock source status.
Run the clock alarm-threshold frequency-offset frequency-offset-value command to configure the alarm threshold for frequency offset at the physical layer.
Run the clock bits { bits0 | bits1 | bits2 } lti-action-2mbps { send-dnu | send-ais } or clock bits bits0 lti-action-2mbps { send-dnu | send-ais } slot slot-id command to configure BITS interface output actions when the 2M ring does not trace the clock source.
Run the clock input-threshold { dnu | prc | sec | ssua | ssub } command to configure the threshold for the input quality level of an external clock source.
Run the clock oam profile ccsa command to configure the CCSA OAM function.
- Run commit
The configuration is committed.
