A high bandwidth telephone line transceiver for connecting telecommunications equipment to a telephone line provides a pair of isolation capacitors connected to the telephone line to transmit the telephone signals across the requisite electrical isolation barrier. A reverse link transmission is used to help characterize the multipath delays that may exist between communicating devices. The apparatus includes a body including at least one first column including at least one receptacle and a second column coupled to the at least one first column. The transceiver may include the receiver and the transmitter. An RSVP PATH message is sent by the correspondent host responsive to receipt of the binding update message.
