Telephone network and telephone communication system

Abstract

This invention relates to electronic communications technology. A telephone network of a structured site of the business office type comprises a local computer network linking computers at the transmitting and receiving ends of the system through network adapters, and also telephone sets. The telephone network is provided with a computer telephony server connected to the local computer network and to the general local telephone network. Each telephone set is connected directly to the local computer network. Connection is made through a telephone adapter and a network adapter connected in series with it. The telephone adapter is capable of converting analog / digital signals adapted to the clock frequency of the local network, user call signals into the addresses of other telephone adapters connected to the local computer networks, and hang-up signals. To establish communication between remote sites having identical telephone networks, the local computer network of each site is provided, in the channel of the external computer network, with a router connected through said channel to routers in other local networks.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a telephone network combined with other electrical systems, which can be applied to realize voice communication between telephone users through a public computer network. Background technique [0002] Currently, telephone service users can be divided into two categories: individual and corporate. The difference between them is not only that individual users use the phone at home, but groups use it in the office. More importantly, the average load on the communication line is 1 to 1.5 times larger for group users than for individual users. [0003] Usually, when a business user uses 2 or 3 local telephone lines (local automatic telephone exchange office number CTO), their connection is no different from that of individual users, that is, between the local telephone exchange office CTO and the business user Lay the connecting wire (twisted pair for telephone), and...

Problems solved by technology

[0016] However, the disadvantage of this communication system is that in order to realize the communication between users, there must be a computer workstation on the circuit between the telephone equipment and the network that can give effective program control to the process of sending and receiving data.

This solution is acceptable for a small number of users, but as the number of users increases, the communication system becomes complicated and expensive due to the increase of hardware equipment
