Abstract:
A method of effecting asymmetric transfer of data between first time division multiplexed (TDM) communication channels of a first of a plurality of TDM communication ports of a TDM communication system, and second TDM communication channels of a second of said plurality of TDM communication ports, said TDM communication ports being adapted to interface serial TDM communication channels coupled thereto, comprising the steps of:(a) storing in memory serial TDM communication channels received from associated serial communication links to which said first and second TDM communication ports are coupled; (b) controllably transferring, in parallel data format, data contents of locations in memory associated with said first plurality of TDM communication channels of said first TDM communication port to locations in memory associated with TDM communication channels of said second TDM communication port; (c) controllably transferring, in parallel data format, data contents of locations in memory associated with said second plurality of TDM communication channels of said second TDM communication port, said second plurality of TDM communication channels being different from said first plurality of TDM communication channels, to locations in memory associated with TDM communication channels of said first TDM communication port; and (d) reading out of memory TDM communication channels transferred in step (c) to said first and second ones of said plurality of TDM communication ports to their associated serial communication links.
