設定を行う必要がある。(Prior art) Conventionally, the common line signaling system is used to control inter-office voice communication between large-scale digital exchanges by controlling a large number of lines (voice channels) using one common line channel that is routed separately from the voice channels. Used to simplify channel trunking. However, since the common line channel controls a large number of voice channels separately from the voice channel, complex network management is required to minimize failures in the common line channel due to failures in the transmission paths between offices, including switching networks. Therefore, it is necessary to set a detour route.

が得られる。OBJECTS OF THE INVENTION It is an object of the present invention to utilize digital interface trunks (e.g., 24 or 30 voice channel control trunks) between offices in small scale digital switching networks;
By using one channel accommodated in the same trunk as a common line channel, controlling other voice channels, and accommodating the voice channel and the common line channel within the same trunk and transmission path, the complicated network that has the drawbacks mentioned above When a common line signaling system is used as an inter-office signaling system, each having a digital interface trunk that does not require management, and connecting via a digital transmission path, the voice channel and the common line channel that controls it are connected to the same digital interface trunk. A common line signaling system is obtained which is characterized by accommodating the following.
（実施例） 次に本発明の実施例について図面を参照して説明する。(Example) Next, embodiments of the present invention will be described with reference to the drawings.

質的影響は起らない。By doing this, if a failure occurs in the digital interface trunks 3 and 4 or the digital transmission line 5, the common line channel cannot be used or the voice channel controlled by the common line channel cannot be used. No negative impact will occur.

等の榎雑な網管理が不要となる。Furthermore, if the above-mentioned failure is resolved one day later, both the common line channel and the voice channel will be able to be used normally again. Therefore, complicated network management such as detour routes for only common channel channels, which was conventionally performed, is no longer necessary.

This has the effect of making management unnecessary.
