Abstract
A system for using an under-utilized data channel for carrying additional data, in a network mode. One such channel is the D-channel in the ISDN system. In one implementation, a group of telephone call centers share data, using the D-channel, about the lengths of time incoming callers must wait before being answered. Using the shared data, the call centers collectively route incoming calls to call centers having smaller waiting times.
