I am in the process of planning a T1 upgrade (1.5MB > 3.0MB) to my company's seperate manufacturing facility.
Currently we have a single T1 data connection, with Adtran Netvanta 3205 routers on each side.
I have ordered (2) Adtran 1202872L1 modules for these existing routers to allow a 2nd T1 to be added giving us 3MB btwn buildings.
I currently have a single CAT5e cable between the Smartjack and the NetVanta. Looking at the wiring for T1's:

This shows that only 4 of the 8 pins are actually used.
My question is: Can I just use the remaining four pins for the 2nd T1 so I don't have to run another cable from the smartjack to the router?
Or is there some reason why that's a bad idea?
TIA
