ABSTRACT:
A telephone exchange provides dial-up switched connections for customers' broadband data terminal equipment (DTE). In response to data received over an associated narrowband channel, the exchange establishes a broadband transmission path to a broadband DTE associated with the narrowband channel. Upon receiving a number for the called party broadband DTE over the narrowband channel, the switch establishes an interoffice broadband channel for communications between the originating and destination DTE.
