hello, i have a backend t1 circuit that i purchased from my local provider and last night it went down. at first we were getting random errors, then it changed to hard down. so when i called my provider they want us to check our inside wiring. so i had our tech check to make sure our connections were good. i called them again and told them that my connections all the way to the demarc are good. but they said they dont see a problem when its crearly that my circuit is down. im not getting any data, plus on the router the interface is down down.

do you have any suggestions on how i can move forward with this. i am stuck and not sure how to proceed.
