becomes possible. In the case of high-speed digital terminals, communication between in-house terminals is also possible.

(2) Enabling effective use of broadband subscriber lines by concentrating in-house terminals.

The line concentration of the in-home terminal will be explained with reference to FIG. No.

The reference numerals in FIG. 3 are the same as those in FIG. Since the terminals in the house are not always in communication, they are connected within the broadband switch 5, as shown in FIG.
Connect only devices that are communicating outside the home. This allows more terminals to be accommodated with a smaller number of broadband subscriber lines 110, thereby making it possible to improve the usage efficiency of the broadband subscriber lines.

(3) Connect the in-home broadband communication device 8 to the broadband subscriber line 1
It can be used as a relay point for 10 points.

FIG. 4 shows a broadband communication device 8 installed in a home.

This figure shows the connection within the broadband line termination section 6 when used as a relay point for the regional subscriber saving line 110. Fourth
The numbers in the figure are those in Figure 1.

is the same as As shown in Figure 4, broad band.

In a home-installed broadband communication device 8 that accommodates two or more regional subscriber saving lines 110, one broadband connection is provided.

Broadband information coming in from the input line is sent to the broadband line termination section 6.
By transmitting to other broadband subscriber lines 110 via the broadband communication equipment installed in the premises.

The station 8 can be used as a relay point for the broadband subscriber line 101.

Next, its usage will be explained using FIG. 5. FIG. 5 is a connection diagram between devices when there are three in-home broadband communication devices. In FIG. 5, 501, 502, 50

connection, and audio information is transmitted through the broadband line termination section 6.

The voice information channel of broadband subscriber line 110 is used for transmission and reception. When a subscriber performs voice communication using broadband subscriber line 110, telephone extension line 112 and voice information line 10
This becomes possible by cross-connecting 9 with the telephone switch section 10. . As described above, according to this embodiment, the in-home communication device according to the present invention is capable of in-home communication, and also has relay-point connection, line concentration function, and voice information termination function.

This allows effective use of broadband subscriber lines.

〔Effect of the invention〕

According to the present invention, there are the following effects.

(1) Communication between in-house terminals is possible.

(2) Broadband subscriber lines can be effectively used by concentrating in-house terminals.

(3) Broadband subscriber line for broadband communication equipment installed in the premises.

Since it can be used as a relay point, it is possible to reduce the number of dedicated lines between offices, which is economically effective.

Especially when there are multiple broadband communication devices installed in the premises.

If the distance between these devices includes both long and short distances, there is no need to install long-distance dedicated lines between offices.

The effect is significant.

(4) Since the voice information from the telephone PBX can be transmitted over a broadband subscriber line, the broadband subscriber line can be used effectively.
