CC Activation Status

In this user interface, you can set and query the activation status of connectivity check (CC).

Navigation Path

In the NE Explorer, click the NE and select Configuration > ATM OAM Management from the Function Tree. Click the CC Activation Status tab.

Cautions

In case of segment level CC, the segments cannot be crossed or contained in each other.
In case of end level CC, the ends cannot be crossed or contained in each other.
The activation command must be issued to the CC source and sink NEs at the same time, with a difference of 3.5 seconds allowed. If the source is not activated in 3.5 seconds after the sink is activated, an alarm may be reported.
When CC is deactivated, the segment and end attribute is invalid.
When the service type of the ATM service is the UNIs-NNI, you can set the Segment and End Attribute for Source. When the service type of the ATM service is UNI-UNI, you can set the Segment and End Attribute for Source and Sink.
