Abstract
A distributed telecommunications switching subsystem ( ) receives and distributes data packets passed between a plurality of switching subsystems or channel banks ( ) and a data packet switch ( ). Each channel bank ( ) has a stored list of addresses. When a channel bank ( ) 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 ( ) 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 ( ) with a matching address or else it is appropriately handled by a last channel bank ( ) in the chain. If the address of data packet matches an address in its stored list of addresses, the channel bank ( ) passes the data packet through a subscriber interface card ( ) to a customer premises equipment unit ( ) corresponding to the address of the data packet.
