3550-US-5.0 CONNECTING A TELEPHONE ANSWERING DEVICE (TAD) RECEIVING FAXES AND OTHER CALLS C) CONNECTING A TELEPHONE ANSWERING DEVICE (TAD) How to Use an External TAD with the Fax When you have a Telephone Answering Device on the fax phone line, the TAD will answer all the incoming calls. Your Brother fax machine will listen in on the line for fax CNG tones. If it hears them, it will take over the call and receive the fax message. If it does not hear fax tones, it will let the TAD continue playing the outgoing message so the caller can leave a voice message. The TAD must answer within 4 rings (2 rings are recommended). The fax machine can not hear the CNG calling tones until the TAD answers the call. When the Ring Delay is set for 4 rings, only 8-10 seconds of CNG calling tones are left for the "handshake". So you must strictly follow the instructions for recording your OGM. You must erase the incoming messages frequently on your TAD. When the TAD's memory is full it will not answer any incoming calls (fax or voice). Set your fax machine's answer mode to TAD (Fax and F/T lights on). FOR YOUR INFORMATION Connecting an External TAD to the Unit You may connect an external TAD to your fax machine, as shown below. Use the "EXT." jack on your fax machine. LINE EXT.
