For a customer premise node with multiple terminal equipment, a multiconnection shaper is required to regulate cells toward the customer loop such that they will be treated as conforming by the enforcer at the public user network interface. However, when setting the arguments of the enforcing algorithm (e.g. generic cell rate algorithm), the cell delay variation (CDV) between shaper and enforcer must be taken into consideration. The authors calculate the CDVs for mapping cells between the ATM layer and the physical layer at the shaper and enforcer.
