The in-house control device connected to the digital sword U human line has
Digital telephones, facsimile machines, and other non-telephone devices are connected to the communication network, and complex communication services such as telephone/non-telephone synchronous communication and switching communication are performed with the communication network. in this case,
The home control device has the ability to decipher, convert, and relay signals from the communication network and from the home appliances.

5'+5'' is the number of connections between the home control device 2, the digital telephone 3, and home devices such as non-1J! The information is decoded and converted in the home control device 2 and relayed to the home devices and the network.Since the local redundant power source alone is insufficient for the home control device 2 to operate, the ACC power source is used for operation. Furthermore, even if the digital telephone 3 is directly connected to the network, it can perform basic telephone operations independently.

Therefore, due to the need to guarantee at least the basic telephone functions even in the event of an AC power outage, the in-home control device 2

However, since there is only one process for disconnecting the tone of each call, there is a drawback that the blood serum is not maintained at all.

In addition, in the case of this type of conventional system, a bypass switching means operates automatically when an AC power outage occurs, and when the power is restored, the digital telephone is in an empty state where it can make or receive calls. There is also a method in which a person manually switches, but it is cumbersome as the 0 person has to check the call control status and manually switch. When Q is in the 1" 1J form, the bypass is not released even though the AC power has been restored, so you cannot receive combined communication services such as simultaneous telephone and non-telephone communication or switching communication. There was a drawback.

In addition, in the event of an ACm power outage, the voltage drop of the AC' power source is rapid, so it is necessary to quickly perform a bypass switching operation.

[Embodiments of the invention]

FIG. 3 is a block diagram of a home control device showing one embodiment of the present invention.

In FIG. 3, 12 is an AC state detection circuit that detects whether the AC power supply is on or out of power, and 13 is in the connection control circuit 7, which disconnects signals from the digital telephone 5 and signals from the network, and performs call control. This is a switching control circuit that detects a stable period and controls the switching circuit 8° 8' for canceling the bypass. The other parts are the same as those in FIG. 2 described above.

The switching control circuit 13 has a function of monitoring signals from both the network and the premises when the Act source is restored, and automatically canceling the bypass by selecting a time when there are few exchanges of call control signals between the network and the premises equipment. have

(1) First, when AC power is applied, the switching circuits 8 and 8' are open (the state shown by the solid line in the figure), and the signal from the network is transmitted from the downlink signal line 10' to the connection control circuit 7 to the switching circuit 8' to the downlink. The digital signal is transmitted to the filling machine 3 through the signal wire O. Conversely, the signal from the digital telephone 3 passes through the upstream signal line 6 - connection control circuit 7 - switching circuit 8 - upstream signal line 6/ to the network 2o.

(ii) The next time the AC power supply fails, the switching control circuit 1
3 detects a voltage drop from the AC state detection circuit 12, and switches the switching circuits δ, 8' to the bypass circuit 9.9/ side (dashed line state in the figure). In this case, the signal from 1120 is transmitted to digital telephone 3 through down signal line 10', bypass circuit 9', switching circuit 8/- down signal line 10.

In addition, the signal from the digital telephone δ is an uplink signal.
It is transmitted to the network 20 through the bypass circuit 9, the switching circuit 8, and the uplink signal 6'. This allows communication between the network and the digital telephone 5 even during a power outage.

It is assumed that a signal system is used that indicates a disconnection state at 010 o'clock. In terms of call control, the states of call connection, incoming call connection, and disconnection are in the process of connection/disconnection procedures, and periods of high signal exchange, while idle and busy states are periods of low signal exchange. Therefore, the switching control circuit 13 monitors the signals from the upstream signal line 6 and the downstream signal line 10/, so that the signal from the network to the home equipment is

'', the continuous 2-bit electric signal from the digital telephone 3 is read (step 27), and if it is ``10'', it is in the starting state, so the bypass release signal is sent to the switching circuit 8.
8' (Step 28.29) o Even if No. 18 from M420 is "OO", "l O", if the signal from '-telephone is not "00"', "'10", Return to step 22 and repeat this operation.

In addition, in this embodiment, the status of the home equipment is expressed using two consecutive bins).
It is clear that this method can also be applied to the FA system.

〔Effect of the invention〕

As explained above, according to the present invention, even when the AC power is switched from a power outage state to a power on state, the bypass circuit is released by selecting a time when there is little signal exchange between the network and the digital telephone, so that when the power is restored, the bypass circuit is released. Composite communication can be performed without interfering with telephone communication, and since everything is processed by machines, there is no need to worry about the hassle or danger of having to manually select a stable state for 119 control and release the bypass circuit. There are advantages.
