ータ・音声送受信用の伝送路を使用している。後者の場
合、両者間の通信路として割り当てられた伝送路上の位
置は固定である。Conventionally, in a communication system between a remote concentrator and a main switch, a dedicated communication path is provided between the two, or a transmission path for transmitting and receiving data and voice is used between the two. In the latter case, the position on the transmission path assigned as the communication path between the two is fixed.
リモート集線装置と本体交換機間に専用の通信路を設け
る場合は、リモート集線装置の数に比例した専用の通信
路を設ける必要があり、非常に不経済である。If dedicated communication paths are provided between the remote line concentrators and the main exchange, it is necessary to provide dedicated communication paths in proportion to the number of remote line concentrators, which is very uneconomical.
また、リモート集線装置と本体交換機間のデータ・音声
送受信用の伝送路を両者間の通信路として使用する場合
でも、伝送路上の通信路の位置を固定とした場合は通信
路障害がリモート集線装置の機能そのものの停止をもた
らす問題がある。In addition, even if the transmission line for data/voice transmission/reception between the remote concentrator and the main switch is used as a communication line between the two, if the position of the communication line on the transmission line is fixed, communication path failure may occur in the remote concentrator. There is a problem that causes the function itself to stop.

続して通信を行なわせる構成である。The communication system of the present invention has an inter-office number assigned to each of a plurality of remote line concentrators. One N097 signal terminal used in the 7 signal system is installed, and the opposing electronic exchange has an interoffice No. 7 signal terminal. No. 7 used in the signal system. A plurality of N7 signal terminals are installed, and a time division switch is installed in each of the electronic exchange and the remote line concentrator, and the N7 signal terminals of the remote line concentrator are installed.
O. 7 signal terminal and the NO. 7 signal terminal of the electronic exchange. 7 signal terminals are connected via a transmission line for transmitting and receiving data and voice between the remote line concentrator and the electronic exchange, and the time division switch of the electronic exchange and the remote line concentrator to perform communication. It is the composition.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

９は本体交換機７のプロセッサである。Referring to a diagram showing an embodiment of the present invention, in the communication system of this embodiment, each of a plurality of remote line concentrators 2 has an inter-office number. No. 7 used in the signal system. One 7 signal terminal 4 is installed, and the opposite main exchange 7 has an interoffice NO.
．． No. 7 used in the signal system. A plurality of 7 signal terminals 8 are installed. Furthermore, a time division switch 6.3 is installed in each of the main exchange 7 and the remote concentrator 2. No. of remote line concentrator 2. 7 signal terminal 4 and main switch 7 NO.
7 signal terminal 8, a transmission line 5 for transmitting and receiving data and voice between the remote line concentrator 2 and the main exchange 7, and the main exchange 7.
The connection is made via the time division switch 6 of the remote line concentrator 2 and the time division switch (concentration switch) 3 of the remote line concentrator 2 to perform communication. Note that 1 is the processor of the remote line concentrator 2;
9 is a processor of the main exchange 7.

とが可能となる。By adopting this configuration, even if the transmission path 5 used as a communication path between the remote concentrator 2 and the main exchange 7 becomes a failure, the time division switches 3 and 6 can be controlled to restore normal operation. It becomes possible to allocate another transmission path 5 to the communication path.
