I've got a frame line thats almost 100% errors, mostly framing. Local
Hardware is a 1604 w/ t1 wic (for testing purposes only. will be a 3640.)
Remote hardware for the 6 pvc's are 1604's w/ t1 wics on fractional frame
lines. Remotes have existing pvcs back to the 3640 on the production
network.
PVCs come up but line protocol bounces continuously.
telco has reported that they can get to their network termination but not to
my csu. I've triple checked the extension from the NIU to the WIC and it
looks good. Its about 75 feet of shielded t1 cable. Tried both clock
source line and clock source internal. on clock source line I lose the pvcs
(deleted). Telco verified lmi type cisco (they had it at auto but changed
to cisco). I tried ANSI on my side and got no LMI rcvs. W/ type set to
cisco LMI enq/rcv is incrementing but drifting all over the place.
Interface resets increment each time I lose line protocol. Carrier resets
are incrementing slowly as well.
Im still suspecting telco issues but any input would be greatly appreciated.
