MG-IP TDM Over IP Gateway Reference Manual
53
As soon as new packets are received and the defect(s) that caused the idle pattern to be sent is (are)
cleared:
Signaling sent on the TSP TX should be updated
Signaling packets should be sent three times to update the peer’s TSP TX
Errored Second Counters
For each TDM interface and for each pseudowire, the TSP must detect and count:
Errored seconds
Severely errored seconds
Unavailable seconds
The IWF must detect an error defect whenever filler data is played out of the jitter buffer. For structure-
agnostic operation, a filler packet is considered a single error defect.
The IWF must count:
An errored second as any second in which one or more error defects are detected
A severely errored second as a second in which the number of error defects is equal to or
greater than the configurable severely errored second threshold
An unavailable second when ten consecutive seconds qualify as severely errored seconds.
This condition will last until ten consecutive seconds occur that do not qualify as severely
errored seconds
CES Configuration Parameters
