[USR-TC] Quad-Analog V.32terbo Modems with an ARC?

The Quad-Analog V.32 Modems, the ones with 4 RJ11's and a big multi-serial port on the back, if you put one of those in a chassis with an ARC, will it route incoming calls to the ARC rather than to the output on the back? Just curious, was thinking about using this for testing things like filters and such without messing with my production unit. Thoughts? Thanks, Joel
