5.3.1.3 AAL5 Error
Conditions
The user can set a global variable for the reassembly coprocessor, RSM_CTRL0
(MAX_LEN), dictating maximum SDU delivery length. The maximum allowable
length, in bytes, of any AAL5 CPCS-PDU, including trailer and pad, is
under reassembly does not exceed the maximum SDU delivery length.
The RS8234 reports this condition via a status queue entry, with the
LEN_ERROR and EPD status bits set. The AAL5_DSC_CNT counter is also
incremented. Refer to
During reassembly, this MAX_LEN value is checked to ensure that the PDU
If the RS8234 receives a non-EOM cell, where
Early Packet Discard is performed.
For each EOM cell where
the PDU is completed, with BA_ERROR status bit set.
