Custom Features on Your Phone Line
If you have Call Waiting, Ring Master, Voice Mail, an answering service, alarm
system or any other custom feature on your telephone line, it may create a
problem in the operation of your MFC.
Connecting an External
Telephone Answering Device (TAD)
Sequence
Your MFC has a built-in aaswering system, but 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 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 8-10 seconds of CNG tones left for the fax “handshake.”
Make sure you carefully follow instructions in this manual for recording your
outgoing message. Do not use a “toll-saver” ring setting on the TAD.
Do not connect a TAD elsewhere on the same phone line — your MFC and TAD
will both try to control the line.
