I don't know ANYTHING about routers and my boss wants to know why we have what looks to be 2 T1 lines going into the 1841 router and only 1 network cable coming out to the network. I don't have a clue but am thinking maybe its a redundancy thing?
I have attached a couple of pictures showing the router and cables.
The red cable is plugged into the port labeled FE 0/0 and the other end of it goes into my network hub/switch.
The blue cables are plugged into slots 0 and 1 which are labeled T1 DSU/CSU. The other end of those cables are plugged into T1 lines.
He wants to know why we can't just get rid of one of the T1 lines!
