4 ESI - Telecom Synchronisation References
With the Quality Selection box, you can select the Minimum SSM level of the incoming signal that is still
acceptable as input signal. If clock reports a lower quality level than the configured minimum SSM level the
system will not use it for synchronization.
Example:
User configured QL-SSU-B as Minimum QL for his system. An E1 input signal reporting either QL-SSU-A or
QL-PRC will be allowed for synchronization, whereas a signal with quality level QL-EEC1/SEC will not be
accepted.
Sa Bits Group
Here you can select between the Sa4 to Sa8 bit group to choose the location for SSM quality bits.
