The present invention relates to a noise blocker for a telecommunications transport network. A noise blocker for a telecommunications transport network includes a signal detector to detect a signal generated by a forward amplifier, a power control unit to control power supply, and a distributor to distribute signals generated by amplifiers. The noise blocker for a telecommunications transport network further includes a bypass circuit to bypass uplink/downlink RF signals when a fault occurs in the power supply. The noise blocker for a telecommunications transport network also includes an NMS to monitor an input/output level value, wherein the NMS outputs an alarm signal when the input/output level value decreases by 6 dB. |
