Custom Features on Your Phone Line

If you have 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 FAX/MFC.

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 4 rings (the recommended setting is 2 rings). The FAX/MFC cannot hear CNG tones until the TAD has answered the call, and with 4 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.
