I'm very new to T1's and routers. Lately our router seem to go down, I'm not sure how to first go about troubleshooting. I do not want to go to the vendor if it's the router. We are using a Cisco 2501 router, and it randomlys goes down. I can't ping the router when it goes down. The only thing I can do is turn it off and on to get it going again.
The LED on the router is on and green. But there's no sign of packets being received or transmitted on the CentreCOM MX20T MAU unit. Any info or tips you can give me is greatly appreciated.
