Did u get the media ever checked from Telco?
Ask them to connect BERT meter on either side for testing the media.
Can u share the show version,show run and show diag from router?
They always bring PRI tester if that's what you mean. they have already upgraded their lines, fiber cables, etc but nothing really changed. Please see attached file.
I suggest you change your e1 card. Try that first before you do any other thing.

since this is more than a year old problem, we're thinking to switch to other carriers. We have two routers at site, 8x E1s to RouterA and 6x E1s to Router B. Cabling and MUX is handled by the carrier. and all E1s flap at the same time. We're using MGCP (unfortunately where im not very familliar to troubleshoot with). my next plan is to try loopback cable. im just checking if there are other ways of troubleshooting that I missed out...
can u try configuring command hwic_t1e1 equalize under one of the E1controllers and check ? this is a hidden command.
after u issue the command, shut/no shut the controller.
you can also refer the discussion for your issue.
The command suggested above is meant to correct a problem with VWIC3 and T1 circuits. it does not apply to other card, and E1 circuits
Hi, I'm investigate for the same issue. I've 4 Cisco AS5400 HPX and XM and I have the exact flapping of 1 sec. No way to fix with provider.
Have you find a solution during these years?
I've also opened a TAC but the TAC staff reply to me that no FPGA upgrade is possible on AS5400.
