Important Safety Precautions
To reduce the risk of fire, bodily injury, and damage to the equipment the follow-
ing precautions must be observed:
Read and follow all warning notices and instructions marked on the product
or included in the manual.
Installation of this equipment has to be done by qualified personnel only.
To achieve safety and satisfactory EMC performance, the plug-in boards
have to be inserted into appropriate subracks. Subrack slots that are not
used must covered with a blanking plate.
The subracks must be connected to earth. This is achieved by installing the
subracks into properly grounded rack or by connecting the protective ground
terminal provided on some subracks to the earthing network.
If the subracks are installed in racks then these racks must be connected to
the earthing network according to ETS 300 253.
Where protective ground terminals are available on the subracks these ter-
minals are marked with the symbol . The following rules must be ob-
served:
The earthing network must be connected to the protective ground termin-
al continuously and securely.
Where the subracks are fitted with an AC power connector the earthing
network must be connected securely to the protective ground terminal
even if the AC power cord is disconnected from the subracks.
The protective grounding may only be disconnected from the subracks af-
ter the DSL line has been disconnected from the plug-in.
Ground terminals on the tabletop modems are marked with the symbol .
The following rules must be observed:
Use of the ground terminal is optional. If used then the earthing network
must be connected to the ground terminal continuously and securely.
Otherwise the ground terminal can be left open.
The grounding may only be disconnected from the modem after the DSL
line has been disconnected.
This product is to be used with telecommunications circuits. Take the follow-
ing precautions:
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifical-
ly designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the tele-
phone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.

ble and located as close to the equipment operator as possible. When you
need to disconnect power to this product, be sure to unplug the power cord
from the electrical outlet.
Ensure that the voltage select switch, if provided on this product, is in the cor-
rect position for the type of voltage in your country (115 VAC or 230 VAC).

2 Overview
2.1 Introduction
The Watson Ethernet modems are SHDSL transmission systems compliant to
ITU-T G.991.2 Annex B (G.SHDSL.bis) and to ETSI TS 101 524 (2006).
SHDSL uses Trellis-coded PAM-16 and PAM-32 linecodes supporting multiple li-
nerates as well as 1-pair, 2-pair and 4-pair DSL transmission.
The Watson Ethernet modems are available as plug-in cards and as tabletop
units. Both plug-in cards and tabletops can work as DSL master modems (STU-
C) and as DSL slave modems (STU-R).
The modems can be configured with an RS-232 terminal through a command
line interface (Monitor).
For remote management a Telnet access to the Monitor is available. The plug-in
modems also have an SNMP agent integrated. One agent can control all plug-in
modems in a subrack and all tabletop modems connected to the subrack mod-
ems.
2.2 Applications
Figure 2-1 shows typical deployment scenarios of Watson Ethernet to deliver
Metro Ethernet Services:
Figure 2-1: Ethernet Services
Several Ethernet plug-in cards 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 either a tabletop

modem or a plug-in card in a tabletop housing is installed. Traffic from each cus-
tomer is available at a dedicated Ethernet interface in the central office. Alterna-
tively traffic from several customers can be aggregated to a single Ethernet port.
Advanced VLAN functions allow for customer isolation and traffic management.
Watson Ethernet modems can also be used back-to-back as shown in Figure
2-2:
Figure 2-2: Campus Networks
For these applications either two tabletop modems or two plug-in modems (in an
appropriate housing) are connected back to back with one of the modems being
configured as DSL master and the other one as DSL slave. Depending on the
distance and the number of wire pairs available linerates up to 22.8 MBit/s are
available. VLAN and MAC Address filtering functions allow for traffic manage-
ment and optimal use of the available DSL bandwidth.
Deployment in linear networks is supported with the Watson Ethernet plug-in
card:
Figure 2-3: Linear Ethernet Network
In Figure 2-3 several sites (e.g. stations along a pipeline or a power line) are
connected with single or two pair DSL systems. In each site a single Watson
Ethernet plug-in card terminates the DSL spans coming from "East" and "West"
sides and gives four local Ethernet interfaces e.g. to connect local station control
equipment. Traffic from the local interfaces can be aggregated with traffic on the
DSL and can be sent to either direction along the line. Traffic streams are kept
separate through VLANs, and Class of Service/Priority functions allow for traffic
management.
