Custom Features on a Single Line

To learn how custom features may affect your faxing operations, please see the Troubleshooting and Maintenance chapter, p. 227.

Connecting an External

Telephone Answering Device (TAD)

Sequence

Although the MFC 7160C has a built-in answering system, you can 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.
