Abstract
A supervising and controlling system for a TDMA equipment in a TDMA station designates one of two control memories in the TDMA equipment as a spare one with the other as operating one by a memory selection signal from a supervisory and control apparatus. The content of the spare memory is periodically verified by the significant control data from the control apparatus. When non-coincidence is detected by the verification, the significant control data is transmitted to the TDMA equipment and is written into the spare control memory without interfering with other stations. Two similar TDMA equipments are provided in the station and controlled by the control apparatus in the similar manner. One of the equipments can be selectively used as an operating one by equipment selection signals from the control apparatus.
