。In recent years, the impact of failures in communication systems on society has become extremely large, so various measures have been taken to prevent a complete disruption of communication in the event of a failure that disrupts communication in switching equipment or transmission lines. It is taken. However, these countermeasures focus on the relay tiers in the communication network where measures such as detour connections can be taken, and it is difficult to take measures against failures at the end subscriber tiers where detours are not possible. In the event of a breakdown in a subscriber exchange that disrupts service, a common measure is to relocate some socially important subscribers from the failed exchange to another, but line switching work requires a large amount of work. In addition, it is difficult to respond quickly because it is necessary to convey connection information not only to the exchange that is to be replaced, but also to the many exchanges involved in the connection.

替スイッチである。FIG. 1 shows a system in which some of the subscribers of a local exchange are redundantly accommodated in the local exchange of another telephone exchange and switched in the event of a failure. In FIG. 1, 1a to In are subscriber exchanges (LSA=LSA) installed at telephone stations A to N, respectively.
, ), 2 is the transit switch (MS) of the subscriber switching hierarchy, 3
4a to 4n are the toll exchanges (TS) of the toll exchange ladder, and 4a to 4n are some of the subscribers accommodated in the subscriber exchanges 1a to 1n, respectively, and are important subscribers (multiple) who should be quickly restored in the event of a switch failure. , 5a to 5n are each subscriber exchange 1a to 1n.
Other general subscribers 6a to 6n are changeover switches for switching subscriber lines, such as accommodating important subscribers to other subscriber exchanges.

局データは加入者交換機1bにも設定されている。The subscriber exchange ladder portion of the communication network shown in FIG. The network configuration is such that the final connection route between them is made through two relay exchanges. Furthermore, an important subscriber 4a accommodated in one subscriber exchange 1a is accommodated redundantly in another subscriber exchange 1b, and the station data of the subscriber 4a is also set in the subscriber exchange 1b.
従って、加入者交換機1bは該交換機の本来の加入者で

。加入者交換機1b−1nについても同様にそれぞれの
重要加入者4b〜4nは他の加入者交換機1c〜1aに
重複収容されている。Therefore, the subscriber exchange 1b always accommodates the important subscriber 4a of the subscriber exchange 1a in addition to the general subscriber 5b and the important subscriber 4b who are the original subscribers of the exchange. In the normal state, the important subscriber 4a is disconnected from the central office at the changeover switch 6a, and the connection process is performed only by the local exchange 1a, so the important subscriber 4a is simply disconnected from the local exchange 1b. The phone is treated as being on-hook. Similarly, for subscriber exchanges 1b-1n, each important subscriber 4b-4n is accommodated redundantly in other subscriber exchanges 1c-1a.
今、第1図において加入者交換機1aに故障が発生し該
交換機が不通になった場合、該交換機1aに収容されて
いる重要加入者4aを切替スイッチ6aを切替えること
によって電話局Bの加入者交換機1bに収容替えする。Now, in FIG. 1, if a failure occurs in the subscriber exchange 1a and the exchange becomes out of service, the important subscriber 4a accommodated in the exchange 1a can be transferred to the subscriber of central office B by switching the changeover switch 6a. It is transferred to the exchange 1b.

早く接続先交換機を切替えることができる。Since the station data of the important subscriber 4a is set in the subscriber exchange ib in advance as described above, the outgoing connection from the important subscriber 4a is possible at the same time as the switching. Furthermore, at the same time as described above, by notifying the trunk exchange 2 that the local exchange 1a is in a failure state, the trunk exchange 2 allows the incoming call connection to the important subscriber 4a to be connected to the subscriber exchange 1b accommodated in the local exchange 1b. Switch the connected exchange so that it is treated as a person. In this case as well, since the information for incoming call connection to the important subscriber 4a via the subscriber exchange 1b is set in advance as the station data of the transit exchange 2, the destination exchange can be quickly switched upon notification of a failure.

交換機が設置され、かつ網構成が前記の条件に適合する
場合には同一電話局内の他ユニットに重複収容しても同
様な効果が得られることは勿論である。In FIG. 1, the important subscriber 4n of the subscriber exchange 1n of the telephone office N is accommodated in the subscriber exchange 1a of the telephone office A in duplicate, but the overlap is not necessarily such that they form a loop as shown in the figure. There is no need to accommodate multiple telephone exchanges, and the exchange that accommodates multiple telephone exchanges may be determined as appropriate, taking into consideration the geographical location of telephone offices, line configurations, traffic conditions, etc. In addition, in FIG. 1, each telephone office is equipped with l units of subscriber exchanges, and one telephone office, for example, the subscriber exchange 1a of telephone station A,
Important subscriber 4a is accommodated in duplicate in the local exchange 1b of telephone station B, but if two or more units of local exchange are installed in telephone station A and the network configuration meets the above conditions, It goes without saying that the same effect can be obtained even if multiple units are accommodated in other units within the same telephone office.

は加入者交換11b経由で発着信が可能となる。The important subscriber 4a of the subscriber exchange 1a is the subscriber circuit 21a.
is accommodated in the subscriber exchange 1a through the changeover switch 6a of the subscriber circuit 21a and the subscriber circuit 2.
It is also accommodated in the subscriber exchange 1b via 1b. The subscriber exchange 1b also has station data set for the important subscriber 4a, but normally the important subscriber 4a is turned off at the changeover switch 6a, so the subscriber exchange is in the same state as the on-footer. When 1a becomes disconnected due to a failure, the maintenance person switches the selector switch 6a and notifies the relay exchange 2, and the relay exchange 2 switches the destination exchange for the important subscriber 4a from 18 to 1b. FIG. 3 shows an example in which the notification and switching means are performed remotely from the maintenance console 23 of the centralized maintenance station. That is, by operating the maintenance console 23, a control signal is sent through the switching control L'A 23a,
In the subscriber exchange 1a, subscriber circuits 21a and 21
The changeover switches 6a and 6c of C are switched, and as a result, the important subscriber 4a is connected to the subscriber circuit 21 by the subscriber exchange 1b.
b, and an outgoing connection is immediately possible. Further, when the general subscriber 5a tries to make a call by switching the selector switch 6C of the subscriber circuit 21c, the caller 5a is connected to the talkie device 22, and a talk message indicating that the exchange is out of order will be heard. On the other hand, a control signal is sent to the trunk exchange 2 through the switching control line 23b, and the control device 24 of the exchange
The station data for making the incoming call connection to subscriber exchange 1b is now used, and the destination exchange is switched. As a result of the above, important subscriber 4a of subscriber exchange 1a
can make and receive calls via the subscriber exchange 11b.

号を送出することによって防ぐ。When the A unit 11a of the subscriber exchange is out of service due to a failure, the important subscriber 14a is transferred to the B unit 11b via the subscriber circuit 31c by operating the changeover switch 16a, using the same procedure as in the principle configuration shown in FIG. Accommodation will be switched. On the other hand, the synchronous terminal device 13 consists of a time switch, and as mentioned above, the line for each destination is set as a semi-fixed path to both units A and 8, but the A unit 11a
If there is a failure, the route change means in the synchronous terminal device 13 switches the semi-fixed path from each destination to the A unit 11a to (13) from the B unit, but the A unit subscribers accommodated in the B unit 11b Since the important subscriber 14a is only a part of all the subscribers of unit A, all lines are not switched, and only some lines are switched to unit B.
Unit) Switch to I1b. For example, a part of the path 13a to the ground R5 is changed to the path 13c and switched to the B unit 11b. The occurrence of an invalid call to the A unit which cannot be connected even if an incoming call is received is prevented by sending a blocking signal from the common line signal processing device 12 to the other party's destination via the common line signal transmitting/receiving device 32.

も迅速に対処することが可能である。In addition, the common line signal processing device 12 has a built-in high-speed processor, and even under normal conditions, it receives the called party numbers of incoming calls to both units A and 8 all at once, and stores them in either unit A or B based on the number. The called party number is sent to the control device of the subscriber exchange through the channel control device 34a or 34b of the accommodating exchange. While the key subscriber 14a is being switched to the B unit, the accommodating exchange is determined based on the table indicating that the important subscriber 14a is being accommodated in the B unit, and in response to an incoming call to the important subscriber 14a, the called party number is sent to the B unit. . Therefore, even if an important subscriber is relocated, it is possible to quickly deal with the situation.

は当然である。In the above, operation of the changeover switch 16a or notification of failure to the common line signal processing device 12, etc. is performed through the changeover control lines 33a to 33d by operation of the maintenance console 33, but the maintenance person manually operates each device. Of course, the same result can be obtained even if the operation is performed manually or automatically without the intervention of a maintenance person. Also,
Although the above example has been explained in which only two units A and B are installed, it is of course possible to perform similar processing even if more units are installed.

信顛性向上に資するところが大きい。As explained above, according to the present invention, an important subscriber of one subscriber exchange is redundantly accommodated in another subscriber exchange in advance, and when a failure occurs in the subscriber exchange, the switching means is activated. , a means for notifying necessary locations of the occurrence of a failure;
By switching the connection destination exchange or changing the route, it is possible to quickly connect calls to and from the important subscriber of the failed local exchange via the duplicate destination subscriber exchange. Therefore, when a failure occurs, communications for important subscribers can be quickly secured without having to change the accommodation of important subscribers, create station data, or change the station data of related exchanges, improving the reliability of the communication network. There is a lot to contribute.
