METHOD FOR SWITCHING CIRCUIT SWITCHED DATA BETWEEN BITSTREAMS USING A CHANNEL IDENTIFIER

摘要

The present invention refers to a method and an apparatus for switching data in a circuit switched synchronous time division multiplexed network from a first bitstream, being received at a first port of a switch, to a second and a third bitstream, being transmitted from a second and a third port, respectively, of said switch. According to the invention, data read from a time slot position of said first bitstream at said first port is associated with a channel identifier that identifies a channel that said time slot position forms part of. The channel identifier is then used at said second port for mapping said data into a time slot position of said second bitstream as well as at said third port for mapping said data into a time slot position of said third bitstream.
