pwTDMCurrentIndications

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 
pwTDMAvePktLossTimeWindow 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.
