You should be able to test that by unplugging the cat5 patch cord to the LAN.

Dear All,
We enable our CDR to work through IP, but the problem our Network is not stable and we want a solution to protect CDR data, so I want to use any tools or solution to indicate that our CAS server is not collecting the data in case of Ethernet cable or Network is unplug or down.

Thank you

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.

I tried to busy out the CDR channel and I got alarm indication on my phone button assigned with CDR1-alrm, but if the CDR is in-service and data network is down do will get it in the warning alarm, because in this case the indication doesn’t appear, if you say YES (it wont appear) that mean I have to escalate it or easier to find out another solution to get indication (not within AVAYA) that the channel stream is stopped.

Thank you

It's been a while since I set it up, but can you use the monitor alarms function in ASA to shoot you an email when the CDR link goes down (I don't recall if you can filter the results by alarm number).

i tested by unplugging the cat5 patch cord to the LAN , the CDR status is up and the alert of button still OFF, and no alert apperas.
do you have solution not within AVAYA may be within LAN technology to alert for data stream if it's down.

Thank you

Two possibilities.

Does your CDR computer have the means to alert you?

Does your network have any devices that can generate an SNMP trap to alert you?

Why is your network not stable?

NO

NO

actully some times it hapens some segment of our network comes Down/UP, and our CAS application needs manual restart to refresh and accept the CDR DATA, thats all, and we invest much mony on this CAS.


Thank you

martinyoung

Have you contacted the CDR vendor to see if they have any ideas?

Yes, I did, and they request us to purchase Netbuffer box from scannex and connected in b/w PABX and CAS, in case the CAS doesn't start to collect CDR data then those data will be stored in that buffer box.

Thank you

martinyoung

When your network drops, how long is it typically down for?

10 to 20 Min

The Definity can buffer that many calls, assuming it knows the link is down. If it thinks the network is up then the calls will not be buffered. In that case you probably need the external buffer.

I still say you are spending time and money on workarounds, your IT people need to stabilze the network. That is the real fix, anything else is bandaids.

thats true, so i will esclated, and close the case.

Thank you
