Configuring ATM Traffic Descriptors
About TDs
When you choose the Forward (or Reverse) TD combination, select the combination
that best describes the traffic characteristics. The UPC and NPC functions use the
traffic parameters to determine the conforming cells of an ATM connection, based on
the threshold values for PCR, SCR, and MBS as specified in the service contract. If a
TD combination is not valid for the service class specified in the Forward (or Reverse)
QoS class field, you cannot select it.
For more information on how each TD combination affects the cell streams under
different traffic conditions, see Appendix B, "ATM Traffic Descriptors."
