Connecting an External
Telephone Answering Device (TAD)
Sequence
You might choose to connect an additional answering system. When you have
an external TAD on the same telephone line as the MFC, the TAD answers all
calls. The MFC “listens” for fax calling (CNG) tones. If it hears them, the MFC
takes over the call and receives the fax. If it doesn’t hear CNG tones, the MFC
lets the TAD continue playing your outgoing message so your caller can leave
you a voice message.
The TAD must answer within four rings. The MFC cannot hear CNG tones until
the TAD has answered the call, and with four rings there are only 8–10 seconds
of CNG tones left for the fax “handshake.” Make sure you carefully follow the
instructions in this manual for recording your outgoing message.
Connections
The external TAD must be plugged into the left side of the MFC, into the jack
labeled EXT. Your MFC cannot work properly if you plug the TAD into a wall
jack.
1
Plug the telephone line cord from the wall jack into the left side of the
MFC, in the jack labeled LINE.
2
Plug the telephone line cord from your TAD into the left side of the MFC, in the
jack labeled EXT. (Make sure this cord is connected to the TAD at the TAD’s
telephone line jack, and not its telephone set jack.)
Do not connect a TAD elsewhere on the same phone line—your MFC and TAD
will both try to control the line.
