Abstract:
1. A telephone network for a structured site, essentially of a business office type, consisting essentially of a common single bus of a local external computer network connecting computers at the transmitting and receiving ends of the telephone network for the structured site and telephone sets connected directly to said telephone network to provide telephone communication between the parties at the transmitting and receiving ends through said local external computer network, wherein said local external computer network is provided with a computer telephony server connected directly to the common single bus of the local computer network and to a general telephone network, each telephone set is provided with a telephone set interface, each telephone set interface being connected, directly through a telephone adapter and a network adapter connected in series therewith, to the common single bus of the local external computer network connecting computers, the telephone adapter being capable of converting analog/digital signals adapted to the clock frequency of the local external computer network, user call signals into addresses of other telephone sets connected to said local external computer network, and hang-up signals whereby the telephone sets can communicate with each other without computers by the telephone sets connected to the local computer network, furthermore the telephone adapter has a transmission channel and reception channels, the transmission channel having a signal detector-distributor with an input connected to a telephone set, a first output of said signal detector-distributor being connected to the input of a tone dialing recognition device having its output connected to the input of a recognized number transmission device, which has its output connected to the local external computer network, a second output of the signal detector-distributor being connected to the input of an analog-to-digital converter having its output connected to the input of a compressor whose output is connected to a processor unit having software to allow exchange of digital data to be effected within the framework of common network protocols, and the reception channels having a voice and tone signal transmission priority device having its output connected to the telephone set, and a first input connected to the output of a call signal dialer, whose input is connected to a call number data converter having its input connected to the local external computer network, a second input of the voice and tone signal transmission priority device being connected to the output of a voice signal transmitter, whose input is connected to the output of a decompressor having its input connected to said processor unit.
