1 INTRODUCTIONThis chapter provides an overview of the OfficeConnect ® 56K LAN Modem,referred to throughout this document as the 56K LAN Modem or simply as theLAN Modem.Introduction The 56K LAN Modem is an easy to install, Local Area Network (LAN) to Wide AreaNetwork (WAN) personal analog IP router. The LAN Modem provides four built-in10BASE-T Ethernet connections for the LAN, while utilizing the V.90 ITU 56Kstandard for WAN access. Combining the 56K LAN Modem with an additionalexternal hub allows total WAN connectivity for up to 25 users.With the 56K LAN Modem, small office and home office users can share remoteaccess 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 standardanalog phone lines. Now, the V.90 56K ITU standard provides download speeds ofup to 56K.1 And your 56K LAN Modem is software upgradable, allowing easyupgrades to new features and enhancements as they become available.For further information, visit 3Com’s 56K web site at http://www.3com.com/56k.Applications The primary applications for the 56K LAN Modem are:n Local networking with shared access to the Internetn Local networking with shared access to a remote office LAN1.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 compatiblewith all US Robotics 56K standards. Standard officially determined in February, 1998; ratification expect-ed in September, 1998.
