Hello,
I am having some trouble with a T1 between a Cisco 1721 router with a WIC-1T and a remote T1 router.
The provider is saying that everything is fine, but the show controller outpout looks strange, and I was looking to get some feedback on the "tranmit ring" section and what it indicates.
Interface Serial1
Hardware is PowerQUICC MPC860 with Integrated FT1 CSU/DSU module
TX and RX clocks detected.
