Can't configure frame relay T1 on Cisco 1760

Solution 1:

You're showing a remote alarm, for that you may find Cisco's troubleshooting guide useful.

Assuming the hardware is good...

I'd check the cabling between your router and the demarc, make sure it's plugged in, not damaged, not a bad cable, etc. Then I'd call the ISP and ask them why it isn't working. Last time I had this happen, it was because AT&T had screwed up and gave me the wrong DLCI, which took a six hour conference call to figure out...

From your update, I see:

     1725 input errors, 595 CRC, 1099 frame, 0 overrun, 0 ignored, 30 abort

Someone more experienced may have better ideas, but this definitely makes me think you have an issue with your cabling, or a noisy line, or the telco clock is completely wrong. It's probably time for that conference call.
