Abstract:
1. A method for switching data to timeslots of one or more outgoing TDM signals, the method comprising: maintaining a set of flags, the flags indicating whether there is a data source for each of a plurality of available timeslots of the outgoing TDM signals; from the set of flags, identifying a number of timeslots of the outgoing TDM signals for which there are data sources; looking up each of the number of timeslots of the outgoing TDM signals in a cross-connect lookup table to identify a data source corresponding to each of the number of timeslots of the outgoing TDM signals; for each of the number of timeslots of the outgoing TDM signals, copying data from the data source to a location corresponding to the timeslot of the outgoing TDM signal; and, looking up each of the number of timeslots of the outgoing TDM signals in the cross-connect lookup table in an order which is the same as an order in which the number of timeslots of the outgoing TDM signals for which there are data sources is identified.
