I don't understand this argument.

Are you connecting your CON directly to something that transports it 
out-of-the-area? Modem?

If you have a consolerouter there with T1 interface as link to outside 
world, what's wrong with having ethernet port from that T1 router to 
the ethernet OOB port on the router needing OOB access, instead of having 
RS232 port on them. It's cheaper and easier to cable ethernet compared to 
RS232. RS232 has much shorter cable length compared to ethernet (9600 
reaches 20 meters or so).
