1. A method to assign a permanent virtual circuit (PVC) to a subscriber, the method comprising:
- obtaining a parameter representative of a port associated with the subscriber;
computing a virtual circuit identifier (VCI) for the PVC from the parameter;
storing the virtual circuit identifier in association with the PVC; and
when the port comprises a remote access multiplexer (RAM) port associated with a RAM to which a device associated with the subscriber is communicatively coupled, computing the VCI for the PVC by;
subtracting one from the parameter to form a first value;
computing a product of the first value and a number of ports of the RAM to; and
adding the product, a second value and an offset to form the VCI, the second value representing a port of a digital subscriber line access multiplexer to which the RAM is communicatively coupled.

5. A method to assign a permanent virtual circuit (PVC) to a subscriber, the method comprising:
-
obtaining a parameter representative of a port associated with the subscriber; computing, with a processor, a virtual circuit identifier (VCI) for the PVC from the parameter; storing the virtual circuit identifier in association with the PVC; and when the port comprises a remote access multiplexer (RAM) port associated with a RAM to which a device associated with the subscriber is communicatively coupled, computing the VCI for the PVC by; subtracting one from the parameter to form a first value; computing a remainder of a division of the first value and a second value, the second value being selected to avoid duplicate assignment of VCI values; subtracting one from the remainder to form a third value, computing a product of the third value and a number of ports of the RAM; and adding the product, a fourth value and an offset to form the VCI, the fourth value representing a port of a digital subscriber line access multiplexer to which the RAM is communicatively coupled.

6. A system to assign a permanent virtual circuit (PVC) to a subscriber, the system comprising:
-
a digital subscriber line access multiplexer (DSLAM); a remote access multiplexer (RAM) communicatively coupled to the DSLAM via a first port of the DSLAM; and a network management system (NMS) to compute a virtual circuit identifier (VCI) for assignment to the PVC, the NMS to compute the VCI based on a first identifier associated with the first port and a second identifier associated with a second port of the RAM with which the subscriber is associated, wherein the NMS is to compute the VCI by; subtracting a constant from the first identifier to form a first value; computing a product of the first value and a number of ports of the RAM; and adding the product, the second identifier and an offset to form the VCI. - View Dependent Claims (7)
