This traffic descriptor type is for no CLP with Sustained Cell Rate. The use of the parameter vector for this type: Parameter 1: peak cell rate in cells/second for CLP=0+1 traffic Parameter 2: sustainable cell rate in cells/second for CLP=0+1 traffic Parameter 3: maximum burst size in cells Parameter 4: CDVT in tenths of microseconds Parameter 5: not used.

This traffic descriptor type is applicable to VBR connections following the UNI 3.0/3.1 conformance definition for PCR CLP=0+1 and SCR CLP=0+1. These VBR connections differ from VBR.1 connections in that the CLR objective applies only to the CLP=0 cell flow.
