DIRECT SWITCH SYSTEM

摘要

A communication system for transmitting messages between calling and called parties wherein the message is divided into predetermined length blocks and transmitted a block at a time. The concept includes the possibility of a very complex system wherein the message is transmitted via communication links from one node to the next node such that the transmitting party does not have a solid connection to the ultimate receiving party. In other words the transmission of a block from one node to the next is completed and satisfactory receipt is acknowledged before the message block is transmitted to a further node. The message blocks can be transmitted at a time when some of the nodes connecting the calling and called parties are busy with other messages such that the message block is stored in each node of the connection path until the following node is clear to receive a new message block.
