Abstract
A method for establishing an end-to-end virtual circuit is provided. The method includes establishing a permanent virtual circuit between customer premises equipment and a digital subscriber line access multiplexer. The method further includes embedding information for a permanent virtual connection between a switch and a remote node in a packet transmitted over a static connection in a network. Finally, the method includes establishing a permanent virtual circuit between the switch and the remote node based on the embedded information.

A method for establishing an end-to-end virtual circuit, the method comprising:
- establishing a permanent virtual circuit between customer premises equipment and a digital subscriber line access multiplexer;
- embedding information for a permanent virtual connection between a switch and a remote node in a packet transmitted over a static connection in a network;
- and
- establishing a permanent virtual circuit between the switch and the remote node based on the embedded information.
A digital subscriber line access multiplexer, comprising:
- at least one channel card coupled to at least one customer premises equipment over a communication line;
- at least one line card, adapted to be coupled to a data network, the line card adapted to provide communication between the at least one customer premises equipment and a remote node coupled to the data network;
- and
- wherein information on a permanent virtual connection between the remote node and a switch of the data network is embedded in a packet transmitted over a static connection in the data network between the at least one line card and the switch.
A method for establishing an end-to-end virtual circuit, the method comprising:
- establishing a permanent virtual circuit between a digital subscriber line modem and a digital subscriber line access multiplexer;
- embedding at least slot, port, VPI and VCI information for a permanent virtual connection between a switch and a remote node in a packet;
- transmitting the packet over a static connection in a data network between the digital subscriber line access multiplexer and the switch;
- and
- establishing a permanent virtual circuit between the switch and the remote node based on the at least slot, port, VPI and VCI information to complete the end-to-end connection.
