The Definity will generate a warning alarm when it loses the CDR link so you could turn on reporting of warning alarms in the maintenance screen. But, and this a very big but, it cannot differentiate one warning alarm from another warning alarm. The Definity generates a lot of warning alarms every day. Depending on the size of your switch and how many things change in a normal day, this will vary from several dozen to several hundred alarms every day 7/24. And whomever is doing maintenance support will get them too.

Warning alarms are considered a trivial alarm and not service affecting so are not reported by default. If you activate reporting warning alarms, be aware that you will be inundated with alarms. 99.9% of them will not be relevant to this problem.

The PBX will buffer CDR data so if the network problem is not long, no data will be lost. I have never gotten a clear answer from Avaya as to how many call records can be stored before the switch starts overwriting old records, maybe Al knows.

Depending on how sophisticated your CDR computer is, perhaps it can alert you. Perhaps the network can alert you by setting a trap if the appropriate segment goes down.

However, these are all workarounds. If CDR data is important to you (and it usually is), the actual solution belongs to your IT folks. They need to provide a stable network because if a segment is down more is lost than just your CDR data. If they cannot, or will not, help you then escalate it.
