Abstract (en)

[origin: WO9748202A1] A system and method are provided for transmitting information over a non-circuit switched network (100). Information of all types is transmitted using a signal digital format. Analog signals are converted to the digital format prior to transmission over the network, and converted back to analog at the receiving end. Transmission between any two or more points (101-116) on the network is made without requiring any switched connections to be established.
