Abstract
A method is disclosed that enables a data-processing system, such as a private branch exchange, to detect and disconnect looping communication channels, without some of the costs, disadvantages, and limitations of techniques in the prior art. The illustrative embodiment of the present invention provides detection of looping communication channels at the point where the loop begins. By detecting at the beginning point of the loop, the illustrative embodiment has the advantage of de-allocating call resources sooner than some techniques in the prior art. This enables the call resources to be reused faster for subsequent incoming and outgoing calls. Faster reuse is advantageous because it can lower the call blocking characteristic, which is related to the probability of a new call not being set up due to lack of communication channel resources.
