### Description

```asn1
mscAtmIfVpcTmTxTdpTable OBJECT-TYPE
SYNTAX SEQUENCE OF MscAtmIfVpcTmTxTdpEntry
ACCESS not-accessible
STATUS mandatory
DESCRIPTION
"This attribute is a vector of five transmit traffic parameters whose
mapping is defined by the txTrafficDescType attribute.

The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR), actual cell rate (ACR), explicit rate
(ER), equivalent cell rate (ECR), and actual shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds.

When txTrafficDescType is 1 or 2, parameters 1 through 5 are
unused.

In this description, PCR is the greater of either the PCR or the
requested shaping rate (parameter 1 or parameter 5) specified in the
txTrafficDescParm attribute under the Vcd Tm or Vpd Tm
component.

When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 or 1 traffic; parameters 2 and 3 are unused.

When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell discard.

When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell tagging.

When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic.

When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell discard; parameter 3 represents the
MBS for CLP equal to 0 traffic.

When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic.

When txTrafficDescType is 3, 4, 5, 6, 7, or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. For CQC-based
ATM cards, the set of available shaping rates is based on the
number of interfaces doing shaping (attribute
perVcQueueInterfaces), and the shapingScalingFactor attribute of
the Arc Cqc Override component. A rate of zero (0) indicates that
shaping is not performed, or that the interface is down.

When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the Cell Delay Variation Toleration (CDVT);
parameter 3 represents the Minimum Cell Rate (MCR); the meaning
of parameter 4 depends upon the value of the abrConnectionType
attribute. if abrConnectionType is sourceDest or
virtualSourceDest, parameter 4 represents the Allowed Cell Rate
(ACR); If abrConnectionType is erSwitch, parameter 4 represents
the Explicit Rate (ER); and if abrConnectionType is efciSwitch,
parameter 4 reflects the actual shaping rate in cell/s for this
connection.

When txTrafficDescType is 3, 4, 5, 6, 7, 8, or 9, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission
characteristics of this connection."
