A personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site. The personal communications system is equipped with two telephone line interfaces to allow connection between two remote sites. The connection between the first remote site and the local site may operate in a voice over data communications mode to simultaneously send compressed voice and data. A digital transmission protocol which is consistent with current packet standards is used to create an independent channel through use of a modified supervisory packet for negotiating communication parameters, including the speech compression algorithm, the speech compression ratio, the communication multiplex scheme, and other operations needed for control of remote hardware interfaces.

A method for negotiating communications parameters between a plurality of transceivers in a packet network, comprising the steps of: uniquely encoding a packet to identify the packet as a communications parameter negotiation request; encoding the packet with codes designating communications parameters; and negotiating the communications parameters, comprising the steps of: (a) transmitting the packet from a first transceiver to a second transceiver, the packet identifying a particular voice compression parameter; (b) receiving the packet in a second transceiver, wherein the second transceiver recognizes the packet and transmits an acknowledgement packet if the voice compression parameter is acceptable; (c) if the first transceiver receives the acknowledgement packet, then using the particular voice compression parameter for communications: and (d) if the first transceiver does not receive the acknowledgement packet, then selecting another voice compression parameter and returning to step (a).
