### Description

```asn1
mscAtmIfVpcTmTxQThreshTable OBJECT-TYPE
SYNTAX SEQUENCE OF MscAtmIfVpcTmTxQThreshEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"This attribute indicates the queue limit and the discard thresholds
for the transmit queue of this connection.

If this connection has unshapedTransmitQueueing attribute
displayed as common, this attribute displays the thresholds of the
common queue. If this connection has unshapedTransmitQueueing
attribute displayed as perVc or as notApplicable, this attribute
displays the thresholds of the per-VC queue.

The first element indicates the queue limit. The provisioned value of
the transmit queue limit is derived from the txQueueLimit attribute
under the service category subcomponents of the CA component for
the service category of this connection.

The second element is the threshold that marks the transition from
congestion state 1 to congestion state 0. This is the threshold at
which traffic with discard priority (DP) = 1 is discarded. This
threshold is set at approximately 90 percent of the first parameter,
the operational queue limit.

The third element is the threshold that marks the transition from
congestion state 2 to congestion state 1. This is the threshold at
which traffic with DP = 2 is discarded. This threshold is set at
approximately 75 percent of the first parameter, the operational
queue limit.

The fourth element is the threshold that marks the transition from
congestion state 3 to congestion state 2. This is the threshold at
which traffic with DP = 3 is discarded. This threshold is set at
approximately 35 percent of the first parameter, the operational
queue limit.

This attribute does not apply to basic Vpts."
