Question
When deleting a discrete service, deactivate it first, and check the alarm at this time. If there is no PS, TU-AIS and other alarms, it means that it is a garbage service. If there is an alarm, it means that the analysis is wrong. At this time, it needs to be activated immediately.

Explanation
Option A is correct because this describes the standard safe procedure for identifying "garbage services" (orphaned or unused circuit paths) in telecom networks - deactivating first acts as a live test without permanently removing anything. The absence of PS (Path Signal loss) or TU-AIS (Tributary Unit Alarm Indication Signal) alarms after deactivation confirms no active traffic was using that service, meaning it is safe to permanently delete. Option B is wrong because skipping deactivation and jumping straight to deletion risks disrupting live traffic if the original analysis was incorrect - the deactivate-first step is precisely the safety net that catches analytical errors. The immediate reactivation step is critical: it restores service within seconds if alarms fire, minimizing customer impact.
Memory tip: Think "Deactivate = Diagnosis." If the network stays silent after deactivation, the service was already dead (garbage). If the network screams (alarms), the service was alive - reactivate immediately and reassess.
