2 Overview
2.1 Introduction
Watson SHDSL router is an innovative Next-Generation DSL solution designed
for enabling high-speed Internet or point-to-point connectivity to business cus-
tomers.
Watson SHDSL router uses Ethernet in the First Mile (EFM) technology, which is
a transparent extension of Ethernet-base LANs into wide area networks. No con-
version of packet formats is required when transiting between LAN and WAN.
This transparency greatly simplifies network operations, reduces deployment
costs, and increase service levels. EFM includes maintenance functions that
make the operation of large wide-area Ethernets feasible.
Watson SHDSL router features either two or four SHDSL ports. Symmetrical da-
ta rates up to 15.3 Mbit/s are available on each copper pair. Using EFM pair
bonding, data rates of 49 Mbit/s over 4 copper pairs can be achieved.
Watson SHDSL router integrates an eight port Ethernet switch, an SPI Firewall
and a VPN gateway, which protects networks by providing robust security fea-
tures and standard IPSec Virtual Private Network tunneling.
Watson SHDSL router features a user-friendly graphical Web-based manage-
ment interface. This highly intuitive GUI is easily mastered by the novice user,
but is also highly flexible and offers sophisticated users and system administra-
tors full control of the system. A description of the GUI can be found in the “Wat-
son SHDSL Router GUI Manual” [1]
