1. A radio communication system for processing information signals received from telephone trunk lines for transmission over a plurality of RF subscriber channels, comprising:

  • network interface exchange means for sampling the received information signals and for sequentially combining the resultant plurality of sampled information signals into a one or more multiplexed transmit channel bit streams, said network interface exchange means further including;

    processor means for dynamically assigning a first of said sampled information signals from one of said trunk lines to an available repetitive slot position of a first of said transmit channel bit streams provided to a first destination node associated with said first of said sampled information signals, said first destination node being determined in accordance with subscriber unit identification information received over said one trunk line;

    means for transmitting a forward interface signal to said first destination node over a network interface channel in response to the first multiplexed channel bit stream;

    and remote telephone exchange means in RF communication with said network interface exchange means over said network interface channel, said remote telephone exchange means corresponding to first said destination node and being located distal from said network interface exchange means, for extracting the first sampled information signal from said forward interface signal and for generating a first subscriber signal on the basis of said extracted first sampled information signal, said remote telephone exchange means including means for transmitting said first subscriber signal over a first RF subscriber channel to a first intelligent subscriber unit, said remote telephone exchange means further including means for routing reverse link signals from said first intelligent subscriber unit to a second destination node;

    wherein a call request signal has accompanied therewith a subscriber identification signal associated with said first intelligent subscriber unit, said processor means further including means for assigning said first sampled information signal to the repetitive slot position corresponding to said first RF subscriber channel at least partially on the basis of said subscriber identification signal;

    wherein said remote telephone exchange means includes a master telephone exchange for generating a first inter-exchange signal on the basis of said first extracted information signal and said subscriber identification signal, said master telephone exchange including master transceiver means for transmitting said inter-exchange signal over an inter-exchange channel; and

    wherein said remote telephone exchange means further includes a slave telephone exchange for providing said first subscriber signal in response to receipt of said inter-exchange signal over said inter-exchange channel.
