Hey guys, I think phrased that wrong. I know that I will get DT from the trunk applying GRD to a "test set" or "butt set" on the frame. I'm talking about the MTA set on the PBX. When I access the MTA set and input the TN I get what sounds like a GRD to me. This seems like it should be normal seeing that it is a GRD trunk. Am I right, or should I be hearing a DT?
