Perhaps I don't have enough time in the field to answer this, but in my experience I've never installed a T-1 where the service provider line did not provide the clocking. Every single T-1 in our network (and that's a bunch) gets its clock from the line. I have no idea why they would choose not to provide clocking and I have no idea what to do to resolve it.
so, I'm not much help! :-) I just wanted to chime in on how odd I thought it was that they weren't providing the clock. good luck, John >>> "Stephen Hoover" 10/3/01 8:46:55 AM >>> I am working on point to point T1 install at a small office. The line protocol keeps going up and down every 30 seconds and I cannot ping myself. My keepalive timers are not incrementing. The telco provider says that they are not providing the clock on this line and that we need to do so ourselves. My condition remains the same whether I set my clock to line or internal. The router on the remote end however seems to be ready to go when they set their clock source to line. When they set to internal, the telco provider sees framing errors on the line. Does it seem feasible that there is a clock source somewhere back towards there end of the line that their router can receive and mine cannot? I am working with the IT staff on the remote end of the link, but none of us seem to have any idea where else to go with this problem. My system works fine when I put my DSU in local loopback and it works when I put their DSU in remote loopback - so I *think* the hardware is sound. Any help is appreciated!
