Note: Three traffic descriptors must be provided for the connections to set the cell
transfer characteristics: Peak Cell Rate (PCR), Sustained Cell Rate (SCR), and
Maximum Burst Size (MBS). The PCR is the highest available cell transfer rate for VBR
connections, or the continuous cell transfer rate for CBR connections. SCR defines the
sustained cell transfer rate for VBR connections that may fluctuate up to the PCR for a
burst length of MBS cells. MBS is what defines the maximum number of cells in a
single burst that can be transmitted above the SCR and up to the PCR in a VBR
connection. SCR and MBS are not applicable to CBR connections. Valid values for MBS
are 32, 50, 100, 150, and 210, and relate to the incoming packet size from the customer
premises equipment.
