Method of operating a bridge for expandable telecommunications system
First Claim
1. A method of transferring information between a transmitting node residing on a first inter-nodal network and a receiving node residing on a second inter-nodal network, each of said nodes including circuitry for transmitting and receiving packetized information over its associated network, said networks coupled in communicating relationship by a programmable bridge node, said method comprising the steps of:
- (a) transmitting a first packet over said first inter-nodal network from the transmitting node, said first packet containing source address information and information which said transmitting node intends to transfer to the receiving node on the second inter-nodal network, said source address information including a network address to facilitate unique identification of a particular inter-nodal network in the event that multiple inter-nodal networks are used to connect the same or different group of nodes, and a nodal address which uniquely identifies a particular node on a particular inter-nodal network;
(b) receiving said first packet at said programmable bridge node; and
(c) selectively retrieving from said first packet any information destined for said receiving node at said programmable bridge node.

Abstract
Methods for interconnecting and transferring circuit switched data (CSD) and packet switched data (PSD) in an open, high speed, high bandwidth, expandable telecommunications system having a plurality of switching and non-switching nodes which reside on one or more inter-nodal networks, including a method of operating a programmable bridge for exchanging information bidirectionally between any two such inter-nodal networks.

26. A method of transferring information between a transmitting node residing on a first inter-nodal network and a receiving node residing on a second inter-nodal network, said networks coupled in communicating relationship by a programmable bridge node, said method comprising the steps of:
-
(a) transmitting a first packet from said bridge node over said first inter-nodal network, said first packet containing information identifying said transmitting node and having a capacity to carry information; (b) receiving said first packet at said transmitting node, said transmitting node performing the steps of; (1) selectively inserting information destined for said receiving node into said first packet, and (2) allowing said first packet to continue transmitting along said first inter-nodal network to return to said bridge node; and (c) at said bridge node, retrieving from said returned first packet said information inserted therein by said transmitting node. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
