PAD switching

The transmission properties of each trunk are characterized by
class-of-service (COS) assignments in the trunk data block (LD 14). The
assignment may be non-Via Net Loss (non-VNL) or via Net Loss (VNL). To
ensure stability and minimize echo when connecting to long-haul VNL (Tie)
trunks, non-VNL trunks are assigned either TransmissionCompensated
(TRC) or Non-TransmissionCompensated (NTC) class-of-service.
