0h
Reserved
(Data pointer.) Initialize to FFFF each time
this queue is initialized.

Initialize to 0 each time this queue is
initialized to maintain future software
compatibility.

T_COND_CELL_CNT
T_SUPPRESS_CNT
A 16-bit rollover count of conditioned cells
transmitted.
A 16-bit rollover count of cells not sent
because of a line resynchronization. Or, if
in UDF-HS mode, a 16-bit rollover count of
cells not sent because TX_ACTIVE is not
set. This counter also counts when cells
are not sent because
SUPPRESS_TRANSMISSION is set.
Initialize to 0 each time this queue is
initialized to maintain future software
compatibility.

Reserved
(Sequence number.) Initialize to 0 each
time this queue is initialized.
The configuration of the current queue.

T_CELL_CNT
TX_HEAD(1:2)
A 16-bit count of the cells transmitted.
Header byte 1 in bits 15:8, header byte 2
in bits 7:0.
9h
TX_HEAD(3:4)
TX_HEAD(5)
Header byte 3 in bits 15:8, header byte 4
in bits 7:0.
Header byte 5 (pre-calculated HEC) in bits
15:8.
A 10-bit quantity representing the number
of byte credits accumulated for the queue.
Stores the average number of bytes in
each cell, and carries the number of DS0s
for this queue.

to this queue for DS0s 15:0 on the line
defined by queue / 32.

to this queue for DS0s 31:16 on the line
defined by queue / 32.
