Cisco 1600 no ping or telnet

Hello.

I am having a number of problems on a remote site linked by a 2mb
leased line, and a cisco 1600 at either end.

The sites are talking perfectly, but the line keeps dropping for a few
seconds at a time, then comes back up again. I have changed the
switches at each end and I am starting to suspect the router is
dropping the interface for some reason.

Also, I used to be able to ping and telnet to the router perfectly, now
I cannot ping or telnet to it from any network, nor from another
router.

This is the info from the router, there are a few interface resets on
the line, is that anything to worry about?

Any help would be greatly appreciated.

Thanks

Tony

For one thing I would clear the counters on these routers and monitor. You
are showing that you have input errors

900 input errors, 10 CRC, 650 frame, 0 overrun, 0 ignored, 215

This usually means you have a dirty leased line..
