摘要： A radio communication system for processing information signals received from telephone trunk lines for transmission over a plurality of RF subscriber channels is disclosed. The system includes a network interface exchange for sampling the received information signals and sequentially combining the resultant plurality of sampled information signals into one or more multiplexed transmit channel bit streams. The network interface exchange includes a processor for assigning a first of the sampled information signals from one of the trunk lines to an available repetitive slot position of a first of the transmit channel bit streams provided to a first destination node associated with the first of the sampled information signals, the first destination node being determined in accordance with subscriber unit identification information received over the trunk line. A transmitter transmits a forward interface signal to the first destination node over a network interface channel in response to the first multiplexed channel bit stream. The system includes a remote telephone exchange, in RF communication with the network interface exchange over the network interface channel, corresponding to the first destination node and located distal from the network interface exchange. The remote telephone exchange extracts the first sampled information signal from the forward interface signal, generates a first subscriber signal, transmits the first subscriber signal over the first RF subscriber channel to a first subscriber unit, and can route reverse link signals from the first subscriber unit to a second destination node independently of the network interface exchange.
