If you are connecting the voice/fax channel to a PBX E&M trunk, connect an RJ-48 phone cable from the VOICE/FAX CHANNEL 1 E&M connector on the DataTalker to an E&M trunk connector on the PBX. (Voice/Fax Channel 2 does not have an E&M connector.) Also, run a ground wire from the ground connector on the back of the DataTalker or RackTalker to frame ground on the PBX E&M trunk. Refer to the PBX manual for the trunk connection.
