  • Method and apparatus for reserving a telephone line in a telepoint communication system
    Patent number: 5633911
    Abstract: A telepoint communication system 100 where the telepoint communication unit (TCU) 125 reserves a communication channel on the communication link 126, where the communication link 126 couples the telepoint base station (TBS) 110 to the public switched telephone network (PSTN) 105. Reserving the communication channel is accomplished by communicating information packets 130,133,136,140,143 and 146 between the TCU 125 and the TBS 110. Reserving the communication channel enables the TCU 125 to ensure the reserved communication is available to route incoming calls received on the telepoint communication system 100 to the TCU 125, particularly when an incoming call is expected.
