Troubleshooting the WAN links

One of the major problems that i face alomost every day , is the problems with the WAN links.

My network is based on leased lines. When i face a problem with a link i try to correct the problem by wathing the status of the serial links. Some of my actions are these:

1. Shutdown and no shut the serial links

2. Check again the ip addresses

3. Restart the routers on both sides and also the modems of leased lines.

4. Change the routers on both sides.

Usually the interfaces on both sides is showing up down.

My question is that:

Is there a way to recognise immediately that the problem is cause in my side(Routers) or on Telcos side.

Thanks a lot

Re: Troubleshooting the WAN links

Jitter is more likely to occur on low-speed links because even a single packet in the queue on a low-speed link can dramatically affect the amount of time a voice packet needs to wait in the queue before being transmitted. Jitter can be an even bigger problem if you do not have priority queuing, such as low latency queuing (LLQ), enabled or configured correctly on your WAN connections
