1INTRODUCTION
This chapter provides an overview of the OfficeConnect® 56K LAN Modem,
referred to throughout this document as the 56K LAN Modem or simply as the
LAN Modem.
Introduction The 56K LAN Modem is an easy to install, Local Area Network (LAN) to Wide Area
Network (WAN) personal analog IP router. The LAN Modem provides four built-in
10BASE-T Ethernet connections for the LAN, while utilizing the V.90 ITU 56K
standard for WAN access. Combining the 56K LAN Modem with an additional
external hub allows total WAN connectivity for up to 25 users.
With the 56K LAN Modem, small office and home office users can share remote
access to the Internet or to a corporate LAN while continuing to network locally.
56K Access 33.6 Kbps was once thought to be the practical limit for speed over standard
analog phone lines. Now, the V.90 56K ITU standard provides download speeds of
up to 56K.1 And your 56K LAN Modem is software upgradable, allowing easy
upgrades to new features and enhancements as they become available.

Applications The primary applications for the 56K LAN Modem are:
■Local networking with shared access to the Internet
■Local networking with shared access to a remote office LAN
1.Capable of receiving at up to 56 Kbps and sending at up to 33.6 Kbps. Due to FCC regulations, re-
ceiving speeds are limited to 53 Kbps. Actual speeds may vary. Requires compatible phone line and serv-
er equipment. The 56K LAN Modem complies with the V.90 ITU standard and is backwards compatible
with all US Robotics 56K standards. Standard officially determined in February, 1998; ratification expect-
ed in September, 1998.
