Please excuse my ignorance but is this module fitted to a router? If so you'll have to run one of the T train IOSs, create a virtual interface if you intend on running rtp compression. You will probably have to apply the service-policy directly to the PVC.
Applying QoS to ATM circuits can be tricky. Here's one I've just installed. Pick through it feel free to use it if you want to
