Abstract
The invention uses a connection having a predetermined priority, switched through the existing call processing switch fabric, to connect between customer premise equipment (CPE). The connection is implemented such that the connection is disconnected if an incoming call to one of the CPEs or an outgoing request for service from one of the CPEs is made that has a priority higher than the predetermined priority. If the connection is disconnected due to a request for higher priority service, the system of the invention can automatically reestablish the connection after the higher priority service call has ended.
