1. A cell interconnect module for transferring call traffic between cells and a switching system in a radio-telephone communications system, the module comprising:

  • a packet transmission bus;

    at least one time-division-multiplexed (TDM) communications link interface connected to the bus, each for time-division-demultiplexing packets carrying voice call traffic generated by a plurality of radio telephones and received from a cell in incoming time slots of a TDM communications link and transmitting the received demultiplexed packets on the bus, and for receiving on the bus packets carrying voice call traffic destined for radio telephones served by the cell which is connected to the TDM communications link and time-division-multiplexing the received packets into outgoing time slots of the TDM communications link; and

    at least one packet communications link interface connected to the bus, each for transmitting on the bus packets received in statistically-multiplexed form from a switching system on a packet communications link, and for receiving on the bus packets destined for the switching system which is connected to the packet communications link and transmitting the received packets on the packet communications link in statistically-multiplexed form.
