A real life situation here with Serial Int.
My boss, the network admin, is trying to install a new router so that we can set have two T1 lines coming in in what he said is a 2 x T1 configuration. He said that he thinks something is wrong with the router because because when he issues the no shutdown command on the Serial interface it won't keep. I asked him if it was connected to the CSU because from what I understand if you don't have clocking for the interface it won't stay up. He's thinking it might be something as extreme as the motherboard, but I'm thinking maybe I could be the hero and go in and figure it out. Do I have to specify that clocking is to be provided by the CSU or is that automatic?
