Description: This attribute indicates the traffic parameter conversion policy used to specify the equivalent ATM bandwidth rate at this end point.

Policy 3 characterizes the traffic in the following way: - ATM traffic descriptor type 6 is selected - PCR0+1 is based on the AR - SCR0+1 is based on the CIR and EIR - MBS0+1 is based on Bc,Be,CIR,EIR and AR - Takes into account that the instananeous rate of the frame relay stream can burst above CIR and up tp the AR.

Policy 4 characterizes the traffic in the following way: - ATM traffic descriptor type 7 or 8 is selected. Type 7 is chosen when non-conforming cells are to be discarded and type 8 when non-conforming cells are tagged by UPC traffic policer. - PCR0+1 is based on the AR - SCR0 is based on the CIR - MBS0 is based on Bc,CIR and AR - There is no direct characterization of EIR. The allowed EIR can be derived using the difference between the AR and CIR.

Policy 5 characterizes the traffic in the following way: - ATM traffic descriptor type 7 or 8 is selected . Type 7 is chosen when non-conforming cells are to be discarded and type 8 when non-conforming cells are tagged by UPC traffic policer - PCR0+1 is based on CIR and EIR - SCR0 is based on the CIR - MBS0 is based on the Bc,CIR and AR - The maximum PCR is no longer based on AR but based on the CIR and EIR.

Policy 6 characterizes the traffic in the following way: - ATM traffic descriptor type 3 is selected - PCR0+1 is based only on CIR.
