I have worked on the telco side and as you can imagine, this happens a bit.. At least you were working with the telco.. You don't know how many people would refuse to change anything.. Did the problem clear after telco testing or after you replaced the wire? That will tell you where the problem was.. I'm curious, how did you know the carrier transitions were within 24 hours? Had you experienced the bouncing and cleared the counters the previous day? If so, those were the only errors you received? For a T1, telco will usually run QRSS, 1's and 0's.. DDS, 2047, 1's and SP5.. More can be run of course but generally not, from my experience.. I remember I used to see a common problem with a certain 12.0x version and 2600 with WIC-1DSU-T1 (imagine trying to tell someone to change their IOS....)
Thanks, Mike Munoz -----Original Message----- From: Ole Drews Jensen [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 03, 2002 4:08 PM To: [EMAIL PROTECTED] Subject: Carrier Transitions : Any Comments [7:30829] My networking skills are apparently being tested these days, because the frame relay circuit went down to one of my branch offices. I got someone at the local office to telnet into the router, which was down/down, and the LMI was down/down, and there were just under 10 carrier transitions in the last 24 hours. I had them powercycle the router without any luck. I concluded that my provider was most likely the cause of the problem, and that it was at the branch office circuit, since my router here was talking fine with the other two remote offices, and my LMI was up/up. My provider told me that the circuit was bouncing, or in other words, it had been going down and back up several times since yesterday evening. After several hours, they did an out of service test, where they told me that it had tested dirty to the CSU but clean to the SmartJack, so they were going to put it on hold until I had replaced the WAN cable and reseated the WIC-1DSU-T1 card in the 1720 router. I went out to the branch office and did that, and the PVC has after I powered it on been up for about an hour now. My question now is: Is this (A) a normal thing that you suddenly have to reseat the WIC and/or replace the WAN cable, and that it can cause carrier transitions, or is this more likely (B) my provider that has found and corrected the error on their site, but now is trying to make it look like it was my equipment that was faulty, or (C) ????
