发明名称 Initialization of communication channel between a subsciber station and a base station in a subscriber communication system
摘要 A subscriber communication system includes a base station in a network with a plurality of subscriber stations, wherein control information is communicated between the base station and the subscriber stations over a radio control channel (RCC) at a frequency selected by the base station from a plurality of predetermined frequencies. The a base station transmits control messages including a unique network number over the RCC. Each subscriber station processes the network number in the control message received over the RCC to enable the subscriber station to process the control message in accordance with whether the subscriber station is in the same network as the base station. The timing of communications transmitted by a subscriber station over a given communication channel between a base station and the subscriber station is refined upon initial establishment of the communication channel. Both DC signaling information and voice data signals are communicated over an assigned channel between a line appearance that couples a base station to a central office and a line interface that couples a subscriber station to a subscriber terminal.
