Hello,
For the last few months, we have been experiencing occassional, brief drops on one of our T1 / PRI circuits. It's probably once every 3 weeks or so. Not too frequent, but nevertheless we would like it resolved.
It's connected to a Cisco 2851 with IOS c2800nm-spservicesk9-mz.124-24.T5.bin
Actions taken on our end:
- Replaced VWIC-1MFT-T1 card
- Changed cable from the VWIC-1MFT-T1 card to the Telco's PRI circuit/card.
- Router has been reloaded
Telco's actions:
- Changed cable pair several times
- Actually installed a new PRI
- Confirmed framing and line code settings are the same as our equipment: Framing is ESF, Line Code is B8ZS, Clock Source is Line
But, it's still happening. The configuration at this problematic site is the same as our many other sites with PRIs/Gateways.
Although I am currently taking the issue up with the Telco yet again, I was wondering if there is anything else I could do on my end to troubleshoot this. Any help is appreciated, thanks!
