Claims

In the electronic switch, a clock (FRS: Frame Sync, BRCLK: Baud Rate Clock) is supplied from each T-Bus Monitor and Repeater Board itself, and each of the T-bus monitoring and relay devices ( TMRB) monitors and relays two bus signals (A, B), and has a function of monitoring each of the T-bus monitoring and relay devices (TMRB) to each other so that an active T-bus monitoring and relay device (TMRB) fails. This causes the stand-by T-bus supervision and relay device (TMRB) to switch over and become active, and the failed T-bus supervision and relay device (TMRB) becomes standby and one bus on the active T-bus supervision and relay device (TMRB). If only the signal fails, only the failed bus signal is duplicated to be supplied by the waiting T-bus monitor and relay (TMRB) to communicate with the upper group processors of the electronic switchboard. Tea and bus monitoring jeunggye wherein monitoring and relaying the bus for the tibeoseu.

2. The apparatus of claim 1, wherein the T-bus monitoring and relay device comprises: clock generation and selection means (33) for generating and selecting the clocks (BRCLK, FRS) required for communication between the upper group processors; First and second relay means (3l, 32) for monitoring and relaying the T-bus signal; T-bus monitoring means 34 for monitoring the state of the T-bus signal; First monitoring means (35) for monitoring a t-bus signal and the first relay means (31); Second monitoring means (36) for monitoring a t-bus signal and the second relay means (32); Connected to the clock generation and selection means 33, first and second relay means 31 and 32, teas monitoring means 34, and first and second monitoring means 35 and 36, wherein each component Redundancy control means 37 for determining the active (Stand-by) according to the state and signal of the bus received from the; And fault detection and alarm generating means (38) connected to the first and second monitoring means (35, 36) and the redundancy control means (38) for detecting a fault and generating an alarm to the outside. T-bus monitoring and relay device.

3. The T-bus monitoring and relay apparatus according to claim 2, further comprising a DC / DC converting means (39) for receiving the power of the T-bus monitoring and relay device itself, and converting the power into necessary power.
