  • Multiple-function digital telephone set in a private branch exchange
    Patent number: 6400817
    Abstract: A system, method, and apparatus for changing the functional mode of a telephone terminal in a private branch exchange (PBX) is presented. A user can issue a command via the keypad indigenous to a telephone terminal, causing the telephone terminal to transmit a request to an interface module, requesting a change in the functional mode of operation of the requesting phone. The interface module responds by causing the software module supporting the current functional mode of operation of the telephone terminal to terminate the logical software link to the telephone terminal and causing the software module supporting the requested functional mode of operation to establish a logical software link to the telephone terminal, thereby changing the functional mode of operation of the telephone terminal.
