AAL2 HEC E
RRORS
A CRC code (used for data integrity checks) is contained in the last byte of an AAL2 header. A
received HEC error could result in dropped packets and poor voice quality.

RRORS
A single bit of the AAL2 header is used as a sequence bit and toggles from 1 to 0 with each
successive transmitted cell. If two cells are received back to back with the same sequence bit, a
sequence error is denoted.

RRORS
Indicates that the Total Access 850 received voice packets that were out of sequence according to
the voice sequencing bits. The Total Access 850 does not drop these packets, but the error is
logged because invalid sequence numbers were received.
