I have looked at that page before I started this conversation but as I said at the very start I have a connection that is up and running on this interface. BUT when I do a debug I see that my router is sending "LCP: O CONFREQ" As if it were trying to start a connection. I can not understand why there is LCP: O CONFREQ packets being sent when the router has negotiated a PPP session on this interface successfully once already. The interface is up and up and passing traffic fine. I came across this when I was looking for debug info on a PPP negotiation problem on another interface on this router.

Thank you for your reply. That is what the doc's on the Cisco site say but that is not what I am seeing. In this negotiation that completes successfully the Magic # and the ID are the same on ID 35. I then captured negotiation that worked. If I am reading this correctly. After ID 35 the LCP state is Open and so on until the route is added.

3640 with 12.2(13b) on a T1 Channelized port point 1) I see that the MagicNumber on ID 60 CONFREQ in and ID 60 CONFACK out are the same. From what I understand this should not be the same number. The "remote" router would see this as a loopback. I have not confirmed this but I will. Point 2) ID does not match. I see this over and over again. The ID numbers change but never match.

We have changed to provide clock on the local end and things are running better. We are still having some trouble. Also we have 2 other T1s that are running better than these that are timing off the line. They are on the same DS3, MUX and Microwave path and end at the same office. Our loop back tests show that when we loop back at the DSX Jacks the T-bird show they run with no errors while testing for 72 hours. Maybe you could check me on this. I know that our IXC is running clear channel. We connect to them on copper with no active network devices. I believe that clear channel is unframed by the IXC. I also believe that clock is recovered from the framing bit. If there is no Framing bit then there can be no recovered clock. Then the Framing bit has to be inserted at the end equipment, correct?

How can I tell if the MUX is providing clock? I am using clocking line now but I am seeing errors. These errors seem to be bursty. The circuits run OK for a few hours at a time then take a stack of errors. I am thinking that this is a timing slip on the WAN (T1 spans). I can not figure out how to isolate the problem. I have removed one T1 from service and did a hard wire loopback at the far end and ran a test pattern on it for 24 hours with out an error. As to the common Timing source issue I don't think that I have that. I am connecting to AT&T which is on one end of a DS3 microwave hop and Telus owns the DS3 microwave equipment that it is "talking" to. Other than each network having it's own stratum one clock. I am told by the carrier that the circuits that I am using are "clear channel" "unframed". This make me think that I can not "recover" clock from the line.

I am having trouble with several Point to Point T1 circuits. Two of these are between a couple 3640 routers. These routers are connected via a T1 to DS3 MUX to microwave hop to DS3 MUX back down to T1. There is no DACS in the circuit. My Current clock source is line on both ends of this circuit but I am seeing show service-module serial 0/0 ... Total Data (last 96 15 minute intervals): 27 Line Code Violations, 601 Path Code Violations 0 Slip Secs, 11 Fr Loss Secs, 21 Line Err Secs, 15220 Degraded Mins 191 Errored Secs, 77 Bursty Err Secs, 11 Severely Err Secs, 0 Unavail Secs I have heard that the clock source should be set to line AND I have heard that it shold be set to "internal". Which is correct for this WAN configuration? If timing off the line on both ends is correct where does the timing on the circuit come from?
