摘要:
A radio communication system for processing information signals received from telephone trunk lines for transmission over a plurality of RF subscriber channels. The system includes a network interface exchange for sampling the received information signals and for sequentially combining the resulting sampled information signals into a multiplexed transmit channel bit stream, each of the sampled information signals occupying a repetitive slot position in the multiplexed transmit channel bit steam. The network interface exchange further includes a processor for assigning a first of the sampled information signals from one of the trunk lines to the repetitive slot position corresponding to a first of the RF subscriber channels associated with a call request signal received over the one trunk line. A transmitter is provided for transmitting a forward interface signal over a network interface channel in response to the multiplexed channel bit stream. The system further includes a remove telephone exchange, in RF communication with the network interface exchange over the network interface channel, for extracting the first sampled information signal from the forward interface signal. The remote telephone exchange also generates a first subscriber signal on the basis of the extracted first sampled information signal, and transmits the first subscriber signal over the first RF subscriber channel to a first intelligent subscriber unit.

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.
