Introduction
About the Router
The Cabletron Router

is a bridge/router designed to provide remote Ethernet
LAN connectivity via a single ISDN line for the small office or home office
(SOHO). The multi-protocol router offers telecommuters, home and remote
office workers high-speed, dial-up access to remote sites, such as the Internet
and the enterprise network. The Router supports IEEE 802.1D transparent
bridging, IP routing and, optionally, IPX routing between Ethernet LAN
networks across an ISDN WAN resource.
The router features an easy-to-use Windows-based management application.
It can also provide two-line analog support for convenient, low-cost use of
standard telephone, facsimile, modem, and answering machine equipment
over the ISDN line. The router manages incoming and outgoing calls, giving
analog calls priority over data traffic as needed.
The router supports Network Address Translation (a.k.a. NAT) which lets
multiple users of a router share simultaneously one low-cost ISDN Internet
connection.
Following is a sample network configuration:
