7 chapter USING THE INTERNAL MODEM Modem Overview The internal modem comes built into some models and is an option for other models. It provides data communications and fax functionality for applications running under Windows 95, Windows 98, and Window NT 4.0. Preloaded software drivers are required for modem operation and allow the modem to easily communicate with software applications. The internal modem supports standard analog modem communication protocols (for speeds up to 33.6 Kbps) as well as up to the ITU-compatible V.90 and industry standard K56flex 56K protocols for higher speeds. IMPORTANT: The V.90 and K56flex protocols allow faster downloads only from V.90 or K56flex compliant digital sources. Maximum achievable download transmission rates are currently unknown, may not reach 56Kbps, and will vary with line conditions. Without having to make hardware changes, the modem may be configured for operation in a variety of countries. An integrated RJ-11 jack provides for simple connectivity to phone cables. If accidentally plugged into a digital PBX phone outlet, the modem automatically protects itself from excessive current until it is plugged into an analog phone jack. Using the Internal Modem 7-1
