I'm sure this is a stupid question, but how does a router connect to a t1 line at the communcation panel? In other words, we have the communication panel where the single t1 telecom circuit terminate at. We have a router with a t1 interface. What type of cable do we bring to the comm panel? RG45? what type of connection is it?
Straight through ethernet patch cable (as long as it is standards compliant and has all 8 wires in it) will work fine. That's pretty much what all the router vendors ship now-a-days to hook their routers up to ports now.
For spec on T1 compatible cable see
If the distance to IXC is long then shiedled cable maybe required.
Quite often Ethernet patch cables are used between router and the T1 circuit termination point, however, thee cables are usally fairly short in length.
