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 FAX/MFC, the TAD answers all calls. The FAX/MFC “listens” for fax calling (CNG) tones. If it hears them, the FAX/MFC takes over the call and receives the fax. If it doesn’t hear CNG tones, the FAX/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 FAX/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 FAX/MFC and TAD will both try to control the line.
