Patent ID: 7742440

Claim:
A multi-standard mobile communication system comprising: a first radio transmitter configured to transmit communications using a first communication standard; a second radio transmitter configured to transmit communications using a second communication standard different from the first communication standard; a digital link, transmitting at a T-1 data rate or an E1 data rate, the digital link comprising a plurality of channels; a controller configured to direct a demultiplexer to allocate a first channel of the plurality of channels to the first communication standard and to allocate a second channel of the plurality of channels to the second communication standard; the demultiplexer comprising: a communication link with the controller; an input configured to receive a multiplexed signal on the plurality of channels of the digital link; a processor configured to: allocate the first channel of the plurality of channels to the first communication standard and the second channel of the plurality of channels to the second communication standard in response to a direction to do so received from the controller over the communication link; and identify a first communication within the multiplexed signal received on the first channel of the plurality of channels of the digital link and a second communication within the multiplexed signal received on the second channel of the plurality of channels of the digital link; a first output configured to deliver the first communication to a first destination; and a second output configured to deliver the second communication to a second destination; wherein the processor is configured to identify the first and second communications within the multiplexed signal received on the first and second channels, respectively, of the plurality of channels received at the T-1 data rate or the E-1 data rate.
