PXF 4333 V1.1
Register Description
0
Queue disabled.
An attempt to store a cell to a disabled queue leads to
discard of the cell and a QIDINV interrupt is generated.
If a filled queue gets disabled, cells may still be in the
queue. In this case the disabled queue is still scheduled,
and cells are logically emitted from the queue but will not
be transmitted.
Actual filling of the queue can be obtained via
QueueLength(13:0) parameter in the QCT entry.
Note: To disable an active VC-merge group, bit
’QIDvalid must be reset. Deactivating the queue
by setting QIDvalid=’0’ automatically starts an
internal process to delete the queue from the VC-
merge group. In response to resetting ’QIDvalid’
the ABM-3G will generate an interrupt (Bit
’UQVCMGD/DQVCMGD’ in Register 103: ISRC)
and reset bit ’MGconf/DQsch’ in this table.
1
Queue enabled.
Cells are allowed to enter the queue.

traffic class table TCT for this core.
Scheduler Block Number (0..127)
