DESCRIPTION
"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
teaPwTDMAvePktLossTimeWindow and comparing it with a
preconfigured threshold [RFC 4553].
-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."
