AFX-150 (430-1240) Features Faxback Doc. # 14115 Your DUoFONE AFX-150 Automatic Fax Switch lets you use your telephone, answering machine, and fax machine with the same telephone line, eliminating the need and extra expense of two phone lines. When a call comes in, you can answer it personally, or you can let your answering machine answer the call. If the fax switch detects the fax alert tones (tones that indicate if the call is a fax call) when you answer or while the answering machine operates, it directs the fax call to your fax machine. If the call is a regular voice call, you can carry on a normal conversation or the answering machine records the caller's message as usual. Your fax switch is easy to install. It connects to existing telephone jacks and requires no special wiring. It also is compatible with most single-line and multi-line non-KSU (key system unit) telephones, and it works with most telephone answering machines and modems. (TK/all-03/13/95)
