Broadband switching networks are disclosed, which have a plurality of broadband switch nodes and a broadband switch inter-node transmission line for connecting the plurality of broadband switch nodes, information being transmitted by cells, each of which comprises a header and an information field, wherein the broadband switch nodes comprise a broadband input and output port for inputting and outputting the cells to and from the broadband inter-node transmission line, and a switch for separating the cells being input through the broadband input and output port and for multiplexing the cells so as to output the cells, wherein data composed of the plurality of cells is transmitted and received through the broadband switch nodes by constant bit rate transmission, variable bit rate transmission, or a combination of the constant bit rate transmission and the variable bit rate transmission.
A broadband switching network having a plurality of broadband switch nodes and a plurality of broadband switch inter-node transmission lines for connecting said plurality of broadband switch nodes, information being transmitted by cells of fixed length, each of which comprises a header and an information field, each of said broadband switch nodes comprising:
A switching network having a plurality of communication channels, the network characterized in that at least one requested communication channel is registered on management tables so as to rapidly handle a resumption request or a repeated call setup request for a call which has been interrupted or disconnected, said at least one communication channel being erased out of of said management tables in accordance with traffic intensity in said network.
A broadband switching network having a plurality of broadband switch nodes and a plurality of broadband switch inter-node transmission lines for connecting said plurality of broadband switch nodes, information being transmitted by cells of fixed length, each of which comprises a header and an information field, each of said broadband switch nodes comprising:
A broadband switching network having a plurality of broadband switch nodes and a plurality of broadband switch inter-node transmission lines for connecting said plurality of broadband switch nodes, information being transmitted by cells of fixed length, each of which comprises a header and an information field, each of said broadband switch nodes comprising:
A switching network having a plurality of communication channels, the network characterized in that at least one requested communication channel is registered on management tables so as to rapidly handle a resumption request or a repeated call setup request for a call which has been interrupted or disconnected, said at least one communication channel being erased out of said management tables in accordance with a communication request of another call necessitating the release of said communication channel.
A broadband switch node for use in a broadband switching network having a plurality of broadband switch nodes including said broadband switch node and other broadband switch nodes and a plurality of broadband switch inter-node transmission lines for connecting said plurality of broadband switch nodes, information being transmitted by cells of fixed length, each of which comprises a header and an information field, said broadband switch node comprising:
A switch node within a switching network, the switching network having a plurality of communication channels, the switch node characterized in that at least one requested communication channel is registered on management tables so as to rapidly handle a resumption request or a repeated call setup request for a call which has been interrupted or disconnected, said at least one communication channel being erased out of said management tables in accordance with traffic intensity in said network.
A switch node within a switching network, the switching network having a plurality of communication channels, the switch node characterized in that at least one requested communication channel is registered on management tables so as to rapidly handle a resumption request or a repeated call setup request for a call which had been interrupted or disconnected, said at least one communication channel being erased out of said management tables in accordance with a communication request of another call necessitating the release of said communication channel.
A broadband switching network having a plurality of broadband switch nodes and a plurality of broadband switch inter-node transmission lines for connecting said plurality of broadband switch nodes, information being transmitted by cells of fixed length, each of which comprises a header and an information field, each of said broadband switch nodes comprising:
An interface arrangement for use in a broadband switching network having a plurality of broadband switch nodes and a plurality of broadband switch inter-node transmission lines for connecting said plurality of broadband switch nodes, information being transmitted by cells of fixed length, each of which cells comprises a header and an information field, each of said broadband switch nodes comprising a plurality of broadband input and output ports for transmitting and receiving said cells to and from other broadband switch nodes using said broadband inter-node transmission lines, each of said broadband switch nodes also comprising switching means for demultiplexing said cells entering the node from either said other broadband switch nodes or end users and multiplexing said cells for transmission to said other broadband switch nodes or said end users according to said header field of each of said cells, said interface arrangement comprising:
