I have 3 private line T1s going into two VWIC-2MFT-T1 cards that are all on the same NM. These VWICs give me four T1 ports of which I am using the last three. The problem I'm having is that I get a tremendous amount of line code violations, slips and other errors on my Cisco 3662 (in corporate office). On the other ends of these T1s, I don't get the errors. These remote ends are set with internal clocking while the 3662 ends are set to line. I have called AT&T and of course they test the line fine and show it to be set up for ESF and B8ZS. I don't know what the problem is. The demarc is extended about 300 ft but playing with the cable length didn't make any difference. We have a PRI that goes into a PBX and it doesnt have any slips or errors. Any help would help. Here is a sample:


T1 3/1 is up.
Applique type is Channelized T1
Cablelength is short 133
