Maximum Length. MAX_LEN x 1,024 is the maximum allowable size in
Enable Programmable Block Size. When a logic high, the programmable
block size VPI/VCI lookup method is enabled. This method consists of
programmable block sizes, and an additional BLK_EN bit in the VCI Index
Table.
VCC Table/VCI Index Table Block Size. This field determines the number of
RSM VCC entries accessed per VCI Index Table entry.

OAM FIFO Full Discard. When a logic high and OAM_QU_EN is a logic high,
an OAM cell will be discarded if the incoming DMA FIFO is almost full.
OAM Enable. Enables detection and processing of OAM cells.
Global Time-out Enable. When a logic high, the automatic reassembly
time-out function is enabled.
bytes of an AAL5 CPCS-PDU, including overhead.
Global Discard Priority. Used by the Frame Relay and CLP discard functions.
If the individual channel priority number is less than or equal to GDIS_PRI,
PDUs on that channel can be discarded.
