Abstract
A system and method for providing dynamic switching functionality in an access network which supports only static switching. Dynamic switching is used to provide connections between a local digital switch and subscribers of the access network wherein the subscribers are connected to remote terminals which only support a static switching protocol. A dynamic switching subsystem is coupled to the local digital switch via a first communication link and coupled to the remote terminals using one or more second communication links. The remote terminals provide nailed up connections between the network terminations of the second communications links coupled to the remote terminals and the subscriber terminations connected to the subscribers. The dynamic switching subsystem provides dynamic switching between network terminations of the first communication link and network terminations of the second communication link. To facilitate dynamic switching, unique call reference values are assigned to the network terminations of the second communication link in the dynamic switching channel. The unique call reference values uniquely identify each of the communication channels of the second communication link from the dynamic switching subsystem to the remote terminals. The unique call reference values are used to provide dynamic connections between network terminations of the first communication link and network terminations of the second communication link in the dynamic switching subsystem.
