Connecting an external telephone answering
device (TAD)
Sequence
You may choose to connect an answering device. However, when
you have an external TAD on the same telephone line as the MFC,
the TAD answers all calls and 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 recommended setting is
two rings). The MFC cannot hear CNG tones until the TAD has
answered the call, and with four rings there are only 8 to 10 seconds
of CNG tones left for the fax “handshake”. Make sure you carefully
follow the instructions in this guide for recording your outgoing
message. We do not recommend using the toll saver feature on your
external answering machine if it exceeds five rings.
■
If you do not receive all your faxes, reduce the Ring Delay
setting on your external TAD, to one or two rings.
■
If You Subscribe to your Telephone Company’s Distinctive
Ring Service:
You may connect an external TAD to a separate wall jack
only if you subscribe to your telephone company’s
Distinctive Ring service, have registered the distinctive ring
pattern on your MFC, and use that number as a fax number.
The recommended setting is four rings on the external TAD
when you have the telephone company’s Distinctive Ring
Service.
■
If You Do Not Subscribe to Distinctive Ring Service:
You must plug your TAD into the EXT. jack of your MFC. If
your TAD is plugged into a wall jack, both your MFC and the
TAD will try to control the phone line. (See illustration on the
next page.)
