Classification: CPC H | IPC H

Claim 10:
11. A signal processing apparatus,
comprising:
a processor; and
a memory having instructions stored thereon that, when executed by the processor, cause the signal processing apparatus to:
determine signal status information based on a power of an obtained optical signal, wherein the signal status information is used to indicate a state of a subnetwork connection carrying the optical signal;
filter the signal status information based on a preset first threshold, wherein the first threshold indicates a minimum duration in which the optical signal is in a valid state; and
determine, based on the filtered signal status information, whether to switch a currently used first clock to a second clock different from the clock, wherein the first clock or the second clock is used to initialize connection monitoring information in response to the determination of whether to switch the currently used first clock to the second clock.
