SNMP Alert Messages - What do these mean?

[pjevnisek]

From time to time I receive SNMP alerts from different BCMs however I don't know what they mean. I've seen these messages more than once and I don't know what kind of impact they have on the operation of the system. Can you help me shed some light on these?

1. Core Telephony - Digital trunking clock in free run.
2. Core Telephony - "Loss of Frame" long term alarm threshold has been exceeded on the DTM.
3. Core Telephony - "Loss of Signal" long term alarm threshold has been exceeded on the DTM.
4. Core Telephony - "Alarm Indication Signal" long term alarm threshold has been exceeded on the DTM.
5. Core Telephony - "Remote Alarm Indication" long term alarm threshold has been exceeded on the DTM.
6. Core Telephony - Digital station loop error.

Any help would be appreciated.
Thanks.

The 1st 5 of those are PRI problems. When the clock is in free run the PRI is down. The digital loop error is possibly a digital station port that is connected to a non digital device.
