T_COND_CELL_CNT Word Format
Field (Bits)
Description
T_COND_CELL_CNT
(15:0)
A 16-bit rollover count of conditioned cells transmitted.
T_SUPPRESSED_CELL_CNT Word Format
Field (Bits)
Description
T_SUPPRESSED_CELL_CNT
(15:0)
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 (refer to “SUPPRESS_TRANSMISSION” on page 139) is set.
QUEUE_CONFIG Word Format
Field (Bits)
Description
TX_COND
(15)
Sends data and signaling from the transmit conditioned data area. Initialize to the proper
value.
TX_ACTIVE
(14)
Enables this queue. To enable sending cells on a UDF-HS connection, assert this bit. To
enable non-UDF-HS connections:
1. Assert this bit.
2. Set the bit corresponding to this queue in the T_ADD_QUEUE table (refer to
section 7.6.2 “T_ADD_QUEUE” on page 128).
3. Assert the CSD_ATTN bit in the CMD_REG (refer to “CMDREG Word For-
mat” on page 165).
To disable non-UDF_HS connections, clear this bit. This queue is then removed from
the calendar queue the next time a cell would have been sent. This queue must not be
returned to the calendar queue until enough time has elapsed for this to have occurred.
NOTE: When reactivating a previously active queue, be sure to reinitialize all the regis-
ters in the queue table for that queue.
