Abstract
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. This is accomplished by using an Extended Addressing Digital Interface (EADI) protocol using hexadecimal characters in the command message rather than decimal characters, thereby creating an 'extended addressing' (EA) capability. The largest five-digit hexadecimal number, FFFFF, corresponds to the decimal number 1,048,575, thereby realizing the ability to exceed one million users, without having to change the size (number of digits) in the command message. Backward compatibility is assured by adding new mode commands that identify a particular command message as being generated by EA compatible equipment.
