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 customers.
Watson SHDSL router uses Ethernet in the First Mile (EFM) technology, which is a transparent ex-
tension of Ethernet-base LANs into wide area networks. No conversion of packet formats is re-
quired when transiting between LAN and WAN. This transparency greatly simplifies network opera-
tions, reduces deployment costs, and increase service levels. EFM includes maintenance function
that make the operation of large wide-area Ethernets feasible.
Watson SHDSL router features either two or four SHDSL ports. Symmetrical data rates up to 5.7
Mbit/s are available on each copper pair. Using EFM pair bonding, data rates of 22.8 Mbit/s over 4
copper pairs can be achieved.
Watson SHDSL router integrates an eight port Ethernet switch, an SPI Firewall and a VPN gate-
way, which protects networks by providing robust security features and standard IPSec Virtual Pri-
vate Network tunneling.
Watson SHDSL router features a user-friendly graphical Web-based management interface. This
highly intuitive GUI is easily mastered by the novice user, but is also highly flexible and offers so-
phisticated users and system administrators full control of the system. A description of the GUI can
be found in the “Watson SHDSL Router GUI Manual” [1]

Several Watson Ethernet plug-in cards (SZ.866.V654) are installed in a subrack at the central office
or the point of presence. Depending on the service offered each plug-in can serve between one and
four customers. At the customer premises a Watson SHDSL router is installed. Traffic from each
customer is available at a dedicated Ethernet interface in the central office. Alternatively traffic from
