What is atmSuSystemHistoryAlrVci?

This OID stores the ATM Virtual Channel Identifier (Integer32) that, combined with the VPI, uniquely identifies the specific ATM circuit where the alarm occurred. Network engineers use the VPI+VCI pair to isolate which voice call, video stream, or data session was affected by the problem. For example, VPI 1 with VCI 32 uniquely identifies a particular voice circuit in the ATM switch.
