cpwCTDMCurrentIndications

The following defects should be detected and reported
upon request:
              
-Stray packets MAY be detected by the PSN and multiplexing
layers. Stray packets MUST be discarded by the CE-bound IWF
and their detection MUST NOT affect mechanisms for
detection of packet loss.
              
-Malformed packets are detected by mismatch between the
expected packet size (taking the value of the L bit into
account) and the actual packet size inferred from the PSN
and multiplexing layers. Malformed in-order packets MUST be
discarded by the CE-bound IWF and replacement data
generated as for lost packets.
              
-Excessive packet loss rate is detected by computing the
average packet loss rate over the value of
cpwCTDMAvePktLossTimeWindow and comparing it with a
preconfigured threshold [SATOP].
              
-Buffer overrun is detected in the normal operation state
when the CE bound IWF's jitter buffer cannot accommodate
newly arrived packets.
              
-Remote packet loss is indicated by reception of packets 
with their R bit set.
              
-Packet misorder is detected by looking at the Sequence
number provided by the control word.
              
-TDM Fault, if L bit in the control word is set, it
indicates that TDM data carried in the payload is invalid
due an attachment circuit fault.  When the L bit is set the
payload MAY be omitted in order to conserve bandwidth.
              
Note: the algorithm used to capture these indications
is implementation specific.
