SUMMARY
Sending a fax from Outlook requires an analog fax modem. If your Integrated Services Digital Network (ISDN) line supports this type of device, it can be used for faxing, however the fax transmission speed will be limited by the fax modem's throughput speed.

If your ISDN line and your fax modem are not compatible, you can send a fax by connecting the modem to a traditional telephone line.



MORE INFORMATION
ISDN is a completely digital telephone/telecommunications network that carries voice, data, and video information over the existing telephone network infrastructure. It is designed to provide a single interface for hooking up a phone, fax machine, computer, and such.

ISDN uses a terminal adapter which replaces the modem to adapt the channels to existing equipment. Traditional telecommunications equipment such as telephones and fax machines can also be attached to the Basic Rate Interface (BRI) if they have the proper hardware and software interfaces.

Dual-channel ISDN combines both B channels of your ISDN line using Multilink Point-to-Point (MP) protocol to connect to the Internet at up to 128 kilobits per second (Kbps). If you make a dual-channel call, you cannot use your second channel for other applications, such as fax or voice calls.
