Abstract
A call processing method and apparatus in which a channel that was allocated to one terminal for processing a call is reallocated to allow another terminal to process the call. The channel is one of several channels of the digital subscriber line. In processing a call, the switching system allocates a channel for the exclusive use of a terminal sharing the digital subscriber line. While the channel is allocated to the terminal, only that terminal can use the channel. The switch enables another terminal sharing the digital subscriber line to process the call by reallocating the channel for the exclusive use of the other terminal.
