A method and system is disclosed that allows for the designation of over 1,000,000 individual users in a communication system, such as an EDACS system, using the existing five-digit portion of command message utilized for specifying the destination address.

Alternatively the decoded portion of the analog waveform may be compared to the specific parameter, and the serial data cursor incremented by a “bit-time” until the specific parameter is found in the serial digital data stream.
