Abstract: A communication method and packet switching system in which packets comprising logical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high-speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers. During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translations on packets of the call. Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate this packet to a designated subsequent node. The nodes provide for variable packet buffering, packet address rotation techniques, and intranode and internode signaling protocols.

Abstract: A trunk controller and processor arrangement for monitoring the error rate occurring in packets received from a high speed trunk. Within a packet switching system, packets comprising logical addresses, and voice/data information are communicated through the system by packet switching networks which are interconnected by high speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers. During initial call setup of a particular call, central processors associated with each network in the desired route store the necessary logical to physical address information in the controllers which perform all logical to physical address translation on subsequent packets of the call. Each network comprises stages of switching nodes which are responsive to the physical address associated with a packet by a controller to communicate that packet to a designated subsequent node.

Abstract: A communication method and packet switching system in which packets comprising physical addresses and voice/data information are communicated through the system by packet switching networks which are interconnected by high-speed digital trunks with each of the latter being directly terminated on both ends by trunk controllers. Customer terminals are connected to the switching system by access line controllers which insert the physical addresses into the packets. The line controllers attach to concentrators which are interconnected to the switching networks via high-speed digital trunks. During initial call setup of a particular call, the physical addresses are obtained and stored in the line controllers by the transmission of a cell setup packet and call reply packet between the originating and destination line controllers. Each processor inserts into the call setup packet the necessary addressing information to route packets through the associated network.
