The serial int that has a WIC-1DSU-T1v2 in my 2620 router says status is down down. The light in the back is AL - amber and CD - green. The interface also has the following status: DCD=down DSR=up DTR=up RTS=up CTS=down
I had the isp test the connection to the demarc and they are saying everything is fine on their side. Please help me troubleshoot.
