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.
