This read-write bitmap controls which services trigger the cwceLteRsrqOnsetNotif notification, using a per-service bit convention defaulting to all 0, and suppressed in technology modes where RSRQ isn't relevant. An administrator enables specific bits to receive degraded-quality alerts only for the services that matter operationally. For example, an engineer monitoring a critical failover data service would enable this flag's corresponding bit to be alerted when that service's RSRQ degrades.
