Possible Causes

This alarm is reported when a conflict occurs in 64 kbit/s cross-connections at the sink end of the channel on which latency is compensated for.


  1. Find the sink end according to the port that reports the alarm, and check whether 64 kbit/s cross-connections are set up between the sink end and multiple source ends.
  2. After the latency compensation takes effect, you are advised not to set up cross-connections between the sink port with other ports to avoid conflict.
  3. If the alarm persists after the cross-connections that are set up with other source ends are deleted, contact Huawei engineers for help.
