Description

Private branch exchange enclosing digital high speed modem with built-in digital high speed modem

The present invention relates to an internal telephone exchange device, and more particularly, to an internal telephone exchange device incorporating a digital high-speed modem.

Private Branch Exchange (PBX) is a branch office telephone, telephone line (exchange) between office telephones, companies, factories, hotels, etc. Hereafter, it is an exchange which performs exchange connection between trunk lines. The telephone extension device is a relay extension telephone of a mechanical contact switchgear from an orbital telephone switchgear that performs all connections such as incoming calls from the trunk line to the station, outgoing connection from the station to the trunk line, or interconnection between stations. After the change of the exchange device and the crossbar internal telephone exchange device, it has changed into an electronic branch exchange (EPBX) with a stored program control method using a microprocessor or IC memory.

1 is a block diagram of a conventional internal telephone exchange device.

In the apparatus shown in Fig. 1, reference numeral 10 denotes a trunk line, reference numeral 12 denotes an extension, and reference numeral 14 denotes an extension telephone. In the premise telephone exchange apparatus shown in FIG. 1, the main function is to interconnect voice signals. Therefore, companies using the local telephone exchange device often have a separate network device installed and operated, so that the investment and maintenance of the facility is made separately, resulting in a large maintenance cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an internal telephone exchange device capable of providing a high speed data service as well as a voice signal by embedding a (non) symmetric digital high speed modem.

1 is a block diagram of a conventional internal telephone exchange device.

2 is a block diagram illustrating a configuration of an internal telephone switchboard incorporating a digital high speed modem according to the present invention.

According to the present invention for achieving the above object, an internal telephone exchange device with a built-in digital high-speed modem at least two or more extension telephones; And a connection exchange and a multimedia data transmission unit for connecting and exchanging a telephone line and a premises wiring connected to the extension telephone and transmitting multimedia data through the telephone line and the premises wiring.

In the present invention, the premises wiring is characterized in that the exchange device and the Ethernet signal line is formed of a single cable.

In the present invention, the connection exchange and multimedia data transmission unit connection connection unit for transmitting a voice signal and a control signal through the extension of the switching device; And an asymmetric high speed modem unit for transmitting multimedia data through the Ethernet signal line.

In the present invention, the extension telephone is characterized in that the Ethernet signal line connection port that can be connected to a personal computer for transmitting multimedia data.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 is a block diagram illustrating a configuration of an internal telephone switchboard incorporating a digital high speed modem according to the present invention.

2, a connection exchange and data transmission unit 200, a plurality of extension telephones 202, a personal computer 204 connected to a plurality of extension telephones, and the connection exchange and data transmission unit 200 The extension telephone 202 is connected to the premises wiring 212, and the telephone station is connected via the telephone line 206. Here, the internal wiring 212 is composed of the Ethernet signal line 208 and the extension 210 of the switching device in one cable.

The connection exchange and data transmission unit 200 connects the telephone line 206 and the premises wiring 212 to transmit multimedia data as well as voice signals and control signals. That is, the voice signal and the control signal are transmitted through the extension 210 of the switching device, and the multimedia data is transmitted through the Ethernet signal line 208.

The connection exchange and data transmission unit 200 is composed of a (non) symmetrical digital high speed modem unit 200a in charge of multimedia data transmission and a connection exchange unit 200b in charge of connection of a telephone line. The connection exchange unit 200b transmits a voice signal and a control signal between the telephone line 206 and the extension telephone 202. The (non) symmetrical digital high speed modem unit 200a transmits multimedia data through the Ethernet signal line 208.

The extension telephone 202 is provided with an Ethernet connection terminal for connecting a personal computer 204 and an external data network.

Since the asymmetric digital subscriber line (ADSL) high speed modem unit 200a according to the present invention uses copper telephone lines, it has excellent versatility to operate anywhere in the country, and has sufficient potential as a next-generation modem product to continue an analog modem. Therefore, the analog modem communication environment, which required a lot of patience for PC users, is expected to disappear in a few years.

Ethernet is a model of a network used for LAN, a telecommunication network in a specific area, and is a coaxial cable network adopted as a standard specification by the Institute of Electrical and Electronics Engineers (IEEE).

Next, the operation of the apparatus shown in FIG. 2 will be described.

The asymmetric digital high-speed modem unit 200a performs initialization according to the control signal of the connection switching unit 200b when the power is turned on, and then (non) symmetrical digital high-speed modem telephone station device (not shown) installed in the telephone station. If a personal computer 204 connected to the extension telephone 202 wants to connect with an external data network while setting up a line and waiting for a transmission channel for transmitting multimedia data, the external data network and the The data exchange between the personal computer 204 is performed, and the data exchange between the personal computer 204 connected to the extension telephone 202 is performed.

Therefore, according to the present invention as described above, since the telephone extension and data network devices are currently installed and operated separately, it solves the problem of separately spending on facility investment and maintenance, and inexpensive premises with less facility investment. It provides the effect of operating switch and network devices.
