Anyone know what circuit type I need to order for OPX with the Onyx VS? I am using a Dual OPX Module.

When I talk with SBC they want to hook up duplicate service when I refer to OPX. I was finally able to get someone that referred to a “2014 Channel OPX PBX” but they need to know if it is Class A, B or C. I think it is Class A but I would like a second opinion before I order the circuit.
