Abstract

PURPOSE:To monitor failure conditions, by taking the specific slot in the frames surrounding the ring shape transmission line as monitor channel, by using the monitor channel of the monitor communication station, and by making correspondence with other communication station in turn. CONSTITUTION:In the signal format, the #1 slot is used for the monitor channel. When the monitor communication station 5 inputs the signal from the synchronizing, the #1 slot is transmitted from the monitor signal (a). The signal of #1 slot is inputted to the communication stations 3a and 3b sequentially and goes round the ring shaped transmission line 1. The communication station in matching with the monitored station address of the monitor signal (a) delivers the response signal (b) consisting of the monitor station status and the response code. The response signal (b) is transmitted to the monitoring communication station 5 and the status signal is received after checking the response code.
