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.
