They did another stress test last night at 11 PM together with the telco, and this time they didn't find any errors. They promised to monitor the line all night, and this morning when I checked the PVC, it had been up all night. I am leaving the case open a little bit longer though.
As I don't have other things to do, one of the other branch offices connected the same way went down during the night. This office is located in an area where they have a different telco, so I am finding this too odd to be a coincidence, and it "smells" like a provider problem at this time. I have not heard back from their NOC yet, but I am warming up with cups of coffee here... In the meantime, I've had them power off their router, reseat both cables, and power it back on. Without any luck. With a telnet, their router shows the LMI being down, and there has been one AIS alarm, which tells me that some upstream equipment are faulty. Thanks for everyone's reply.
