Cisco WIC-1DSU-T1 timing problem
I have a ptp t1 between two sites, with a cisco 2600 (with 12.3) with a WIC-1DSU-T1 in each router. I've been having some issues with the t-1 dropping out, and have been told that it's a timing issue, where i need to have one router pull time from the line, and one router provide time to the line. As far as i can tell, both routers are set to pull time from the line
both configs are the same as below:
no network-clock-participate slot 1
no network-clock-participate wic 0
and i need to get this fixed. I've been doing some dinking around
RR-Scotts(config)#network- clock-part icipate slot 1
Slot is empty or does not support clock participate
RR-Scotts(config)#network- clock-part icipate wic 0
WIC slot is empty or does not support clock participate
but apparently i'm either not in the right area, or i've missed something along the way.
i'm comfortable working in the router, but dont have a clue as to what i should be working on!
any help would be most appreciated!

I have never heard of a PTP T1 having a timing issue liek you described. Does it drop on both routers? Have you looked to see if maybe the router is rebooting? I had that problem with one of my routers when the Telco told me I had a 'Timing issue'. I fixed my problem by adding RAM to my router. That however, is probably not your problem.
I've been seeing a lot of this type issue in these forums lately. With leased line point-to-point T1 lines, the telco often will not provide the proper T1 timing, telling the clients that they need to provide their own T1 clock source. This is simple to do with the service module settings and providing the clocking and rate on one end.

your solution did indeed fix my timing issue.. now to wait and see if that was indeed the issue causing this problem!
thank you for your quick response.
you're exactly right about the telco not providing time on the line. nothing has changed in the routers in the 7 months since they've been up and running (just fine the entire time, might i add) but telco says the problem is on my end, so i've already replaced the csu/dsu, and now have set my timing.
now to play the wait game!
