Connecting an External Telephone
Answering Device (TAD)
Sequence
When you have an external TAD on the same telephone line as the
machine, 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 does not hear the CNG tones, the machine will not answer
the call, and messages can be left on the TAD by callers in the normal
way.
The TAD must answer within a maximum of four rings. However, we
recommend two rings as the TAD setting. 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 instructions in this manual for recording your
outgoing message. We do not recommend using the toll saver feature on
your external answering machine if it exceeds 4 rings.
Do not connect a TAD elsewhere on the same phone line—your machine
and TAD will both try to control the line.
