Abstract

An apparatus and methods for a wireless telecommunication system to provide a wireless interface. A plurality of modems is used for processing wireless communications with a plurality of subscriber line circuits, each for providing a telecommunication connection. A control processor assigns a modem for each communication, selects one of the line circuits and associates that line circuit with the assigned modem for that communication. Thus, any of the line circuits can be used to communicate via any of the modems.
