SSCOP Errored PDUs Counter. This counter counts the
sum of the following errors:
1) Invalid PDUs.
These are defined in SSCOP and consist of PDUs
with incorrect length (MAA-ERROR code U),
undefined PDU type code or not 32-bit aligned.
2) PDUs that result in MAA error codes and are
discarded
See Errors A-M and Q-T defined in ITU-T Q.2110 [13].
