Field (Bits)
Description
LOW_CDV
(15)
This bit is used in unstructured mode to decrease the
CDV. If this bit is set then the cells are scheduled every
47 bytes, otherwise the scheduling is frame based. This
mode cannot be used when the queue is configured for
partial cells or for AAL0 mode. By default, a high speed
queue is always configured for low CDV and this bit is
ignored.
1
Unstructured line is in low CDV mode (byte based
scheduling)
0
Unstructured line is not in low CDV mode (frame
based scheduling)
REF_VAL_ENABLE This bit enables the generation of the reference value
for this line when adding queues.
(14)
T1_MODE
(13)
Determines mode of the line
Line is in T1 mode. If HS_UDF is also set, the
1
highspeed line will play out of framed DS3 AIS when in
underrun.
0
Line is in E1 mode.
