Abstract: A video telecommunications delivery network (10) provides video channels to a plurality of set top units (24). Each set top unit sends a video channel request to an associated cell multiplexing unit (20). If the video channel is available, the cell multiplexing unit (20) provides the video channel to the set top unit (22).

If unavailable, cell routing unit 18 provides the video channel request to a digital multicast bank (16). Digital multicast bank (16) delivers the requested video channel if available, otherwise the video channel request is routed to a video information provider (12) through an asynchronous transfer mode (ATM) switch (14).

The method comprises receiving a frame of communication signals wherein some of the communication signals represent ISDN D-channel signals wherein each ISDN D-channel signal is represented by a first number of data bits and a second number of other bits. A first copy of the frame of communication signals is stored in a first memory while a second copy of the frame of communication signals is stored in a second memory during a first frame period. During a second frame period, at least some of the stored communication signals are retrieved from the first memory and at least some of the stored communication signals are retrieved from the second memory. Multiplexed signals are then assembled wherein at least one multiplexed signal comprises a multiplexed combination of the data bits of ISDN D-channel signals retrieved from the first and second memories.

Abstract: A distributed telecommunications switching subsystem (100) receives and distributes data packets passed between a plurality of switching subsystems or channel banks (102, 104, 106) and a data packet switch (110). Each channel bank (102) has a stored list of addresses. When a channel bank (102) receives a data packet, it compares the address of the data packet to its stored list of addresses, and transmits the data packet to another channel bank (104) if the address of the data packet does not correspond to any of the addresses in its stored list of addresses. The data packet is passed on until it reaches a channel bank (106) with a matching address or else it is appropriately handled by a last channel bank (106) in the chain. If the address of data packet matches an address in its stored list of addresses, the channel bank (102) passes the data packet through a subscriber interface card (120) to a customer premises equipment unit (108) corresponding to the address of the data packet.
