This is kind of crazy, but is it possible to connect wire pairs between two locations (ordered from local telco) if we only have 2 wires (1 set of cable pairs) rather than 4 wires (2 sets of cable pairs)? If we had 4 wires, we could use T1 WICs but what to do if we have only one pair? I've been playing around with trying to make a crossover cable crossing over only 1 set of wires but that hasn't worked, not too surprising, since T1 WICs are 4-wire. Any ideas appreciated.
Hmm T1's are a fair bit outside my comfort zone.
But I know that some T1/E1 controllers support the following command
line-mode 2-wire line-zero
Perhaps you can check if yours do.
Thank you for your response. This sounded promising. I tried looking into that but those options don't exist with the T1 WIC in there. It looks like you need a DSL WIC to get these configuration options.
There are many products that can work over a single pair. Some made by Cisco, some not.
It really depends on your budget and requisites.
