Abstract: Reverse powering equipment includes: a power supply module, configured to supply power resources to a distribution point unit by using a line; a switch, configured to control whether the power supply module supplies power; a line test module, configured to: when the switch is opened and the power supply module does not supply power, test whether a user terminal is connected to the line; and a system control module, configured to send an alarm signal when the line test module determines that a user terminal exists on the line, and after a user disconnects the user terminal, control the switch to be closed and the power supply module to supply power. The reverse powering equipment can prevent the user terminal from being damaged.

Abstract: A signal processing method, a related device, and an apparatus for intelligently changing a signal frequency band according to a requirement during downlink or uplink signal transmission. The disclosure includes splitting a downlink signal into a first downlink signal and a second downlink signal, where the second downlink signal is a signal defined by a preset standard, and the downlink signal is an analog signal; performing an analog-to-digital conversion on the second downlink signal to obtain a third downlink signal; filtering the third downlink signal to obtain a fourth downlink signal; performing a digital-to-analog conversion on the fourth downlink signal to obtain a fifth downlink signal; and combining the first downlink signal and the fifth downlink signal to obtain a downlink output signal.
