Will communication be interrupted if a fiber breaks in the middle of the optical fiber ring network?

The IDM M9000B communication command and dispatch system supports up to 8 optical fiber ring networks, and every two rings share 30 telephone channels; if a fiber at some point in the middle of the ring network is broken, normal communication is not affected. A call is connected as soon as the handset is lifted at the remote end and images are displayed synchronously; broadcasts and transfers can be made to each job role, and telephones and trunking intercoms can monitor at the same time, realizing audio and video dispatching that combines fixed posts with mobile posts. IDM MPconv cards are used as the ring network cards, and the remote end connects to IDM NTD421 equipment; during installation, reserve card slots according to the number of rings and the voice channel requirements of each ring. Projects with distributed sites that require long-distance post deployment are suitable for this ring network networking mode.
