Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 In the present invention, the base unit has a modem signal connection unit that can be connected to a general subscriber telephone line (analog public telephone line), and a slave unit has a connection unit that can connect to a modem. The present invention relates to a home (parent / child) digital cordless telephone capable of data communication between connected modems.

[0002]

[Prior art]

 In order to connect a modem connected to a personal computer indoors to a general telephone line, the connection between the modem and the indoor connection of the general telephone line must be connected by wire. .

[0003]

[Problems to be solved by the invention]

 When the modem connected to the personal computer and the installed general telephone line connection are considerably far apart, connect the personal computer and modem near the general telephone line connection or use the general telephone line connection. There is a problem that the connection must be extended to near the personal computer and the modem, or the connection between the general subscriber telephone line and the modem must be connected by a long wire.

[0004]

[Means for Solving the Problems]

 In order to solve this problem, the present invention has installed a connection unit that can be connected to a general subscriber telephone line on the base unit of a home-type digital cordless telephone, and a connection unit that can be connected to a modem. By connecting the newly installed base unit connection to the general subscriber telephone line and the slave unit connection to the modem, cordless connection for data communication between the general public telephone line and the modem is possible. To

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 (a) shows an embodiment applied to a base unit of a home type digital cordless telephone, and FIG. 1 (b) shows an embodiment applied to a home unit of a home type digital cordless telephone. It is a basic block diagram of a handset and a slave unit.

In the home type digital cordless telephone, the base unit is constituted by the radio circuit unit 1, MODEM 2, TDMA-TDD control 3, voice CODEC 8, telephone network connection unit 9 and the like shown in FIG. b) The wireless circuit unit 11, MODEM 12, TDMA-TDD control 13, audio CODEC 18, etc. In one embodiment of the present invention, a connection switching unit 4 is set between the TDMA-TDD control unit 3 and the audio CODEC 8 in the master unit shown in FIG. The connection switching unit 4 includes an adapter 5 for A / D and D / A conversion, a switch 6 for switching the connection of the TDMA-TDD control unit 3 to the adapter 5 or the audio CODEC 8, and a connection for connection to a general public telephone line. The connection part 7 is constituted. Further, a connection switching unit 14 is set between the TDMA-TDD control unit 13 and the audio CODEC 18 in the slave unit shown in FIG. The connection switching unit 14 includes an adapter 15 for AD and DA conversion, a switch 16 for switching the connection of the TDMA-TDD control unit 13 to the adapter 15 or the audio CODEC 18, and a connection unit 17 for connection to a modem. It is configured.

Here, MODEMs 2 and 12 are MODEM circuits for performing modulation / demodulation of π / 4 shift QPSK and switching reception diversity, and TMDA-TDD controls 3 and 13 are time division multiple access, time division duplex, scrambling, error control, The TMDA-TDD control circuit for performing timing detection and the audio CODECs 8 and 18 are audio CODEC circuits for performing ADPCM audio compression encoding processing.

By connecting the TMDA-TDD control 3 and the adapter 5 with the switch 6 of the connection switching unit 4 and the TMDA-TDD control 13 and the adapter 15 with the switch 16 of the connection switching unit 14, the general public telephone line and the personal computer can be connected. A cordless connection with a modem enabled mutual data communication. Also, by connecting the TMDA-TDD control 3 and the voice CODC 8 with the switch 6 of the connection switching unit 4 and the TMDA-TDD control 13 and the voice CODC 18 with the switch 16 of the connection switching unit 14, a normal home digital cordless telephone can be obtained. Can be used.

[0009]

【Example】

 If the voice CODEC 8 and the telephone network connection unit 9 in FIG. 1A and the voice CODEC 18 and the microphone 19 and the receiver 20 in FIG. 1B are removed and the voice communication function is deleted, the data communication function is limited. It can be used as a compact home-type digital cordless telephone. If the connection unit 17 of the slave unit is manufactured as a connection unit corresponding to a connection terminal of a modem of a personal computer, for example, a connection unit for a PCMCIA type modem, it can be used as a home type digital cordless telephone integrated with the personal computer.

[0010]

[Effect of the invention]

 Even if the modem connected to the personal computer and the general subscriber telephone line connection unit are not connected by wire, the connection between the personal computer and the general public telephone line can be made at any place where the home-type digital cordless telephone can be used. It is possible to use data communication using general public telephone lines such as personal computer communication.
