Abstract:
A telecommunications switching network, comprising:a plurality of modules for accepting input signals having different protocols, and for generating output signals encapsulated in a specified protocol; a central stage switch for switching signals in said specified protocol from input ports of said central stage switch to output ports of said central stage switch; and said plurality of modules for converting signals of said output ports in said specified protocol to any of said plurality of protocols of said input signals; characterized in that:said central state switch comprises apparatus for switching only broadband signals, and comprises apparatus for converting narrowband signals transmitted to said central stage switch into broadband signals, one broadband signal for each narrowband signal; network further comprising: apparatus for adding an indicator to all signals converted from narrowband signals into broadband signals at said central stage switch to differentiate between broadband signals and narrowband signals.
