Before using this unit:
Read this manual completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
Hazardous voltage may occur within this unit when connected to power supply
or TNV circuits.
Prevent access to hazardous voltage by disconnecting the unit from power supply
and all other electrical connections.
Prevent damage to internal electronics from electrostatic discharges (ESD) by
discharging your body to a grounding point (e.g. use of wrist strap).
Before installation:
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the power supply. Ensure compliance to
national installation regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit,
follow the spacing recommendations (see Installation section).

Description
Functional description
SHDSL represents the best of several symmetric DSL technologies that have been combined into a single industry standard. The DDW-100 is designed as a transparent Ethernet
Extender (Ethernet Bridge) for 10/100BaseTX networks. It is transparent for multicast
addressing, VLAN packets, VPN pass-through for IPSec and for protocols like MODBUS/
tcp and Profinet.
SHDSL allows the re-use of existing twisted copper pair with data rates from 192 kbit/s
to 2.3 Mbit/s in both directions (Symmetric DSL), according to standard ITU-T G.991.2.
Based on the quality of the line and the communication speed, distances up to 10 km can
be achieved, this however depends of the quality of the line and cable characteristics.
This differs from application to application, therefore a unique feature is implemented
providing reliable-, normal-, or high speed mode.
Distance on /data rate without noise, cable type is AWG24, 0,2 mm
Tested distances with Cat 5 cables
192 kbit/s >6 km
384 kbit/s >6 km
512 kbit/s >6 km
768 kbit/s >6 km
1024 kbit/s >3 km
1280 kbit/s > 3 km
2048 kbit/s > 3 km
2304 kbit/s > 3 km
Distances up to 10 km at 192 kbit/s have also
2
been verified with a 1mm
cable.
Description of used nomenclature:
Noise margin:
The margin between signal and noise (dB)
2
CO/CPE:
CO (Central Office) answering central unit, the CO configures the CPE when establishing a connection. CPE (Customer Premises Equipment) is the unit that initiates the connection.
Annex A and B:
Annex A in ITU-T Rec. G.991.2 describes those specifications that are unique to SHDSL
systems operating under conditions such as those typically encountered within North
American networks.
Annex B in ITU-T Rec. G.991.2 describes those specifications that are unique to SHDSL
systems operating under conditions such as those typically encountered within European
networks.

Getting started
The DDW-100 is easy to use and install, the units work in pairs, one as has to be configured as CO (Central Office) and one as CPE (Customer Premises Equipment). This configuration is made with DIP-switches situated under the lid of the DDW-100.
X Connect the SHDSL Line
There are two options for connecting the SHDSL line:
1) Connect the twisted pair to DSL screw terminal 1 and 2 (polarity independent)
situated atthe base of the DDW-100
2) Connect the line using the RJ-12 port on the front panel of the DDW-100.
Note! that these two connections are parallel, it is not possible to connect both
at the same time.
Y Connect the Ethernet Line
Connect Ethernet to the TX port onthe front of the DDW-100.
The factory settings for the DDW-100 is plug and play mode where TX port
is enabled for:
… Ethernet Auto-negotiation enabled.
… Auto MDI/MDI-X.
… Auto-polarity enabled.
The DDW-100 will automatically sense the data rate of the connected unit and cable
type.
Z Settings in the units
The units operate in pairs, one as CO (Central Office) and one as CPE
(Customer Premises Equipment). Factory setting in the DDW-100 is as CPE.
Note! Before connection and installation one of the connecting units have to be
reconfigured as a CPE, see DIP-switch S1:4.
Depending on the quality of the line and the distance there is possibility to select the
optimised speed.
This is done via DIP switches in the unit configured as CO. Factory default is 192 kbit/s.
When selecting higher speed note if the DSL link is established, if not, the selected speed
is too high for the distance.

Diagnostic information:
The DDW-100 can display diagnostic information using a terminal. program
1) Connect a Westermo standard cable 1211-2026 (two metre 9-pole D-sub)
to the RS-232 interface located under lid.

* To minimise the risk of interference, a shielded cable is recommended when the cable is located
inside 3 m boundary to the rails and connected to this port.
The cable shield should be properly connected (360°) to an earthing point within 1 m from this
port. This earthing point should have a low impedance connection to the conductive enclosure
of the apparatus cabinet, or similar, where the unit is built-in. This conductive enclosure should
be connected to the earthing system of an installation and may be directly connected to the
protective earth.

DIP-switch settings
!
Before DIP-switch settings:
Prevent damage to internal electronics from electrostatic discharges (ESD)
by discharging your body to a grounding point (e.g. use of wrist strap).
NOTE DIP-switch alterations are only effective after a power on.
A setting configured by any other method during normal operation, overrides
the DIP-switch setting. However, at power up, the DIP-switch settings have precedence over the setting configured by any other method.

Description of normal, high-speed and reliable mode
With SW2:2, 3 the DDW-100 is set to reliable, high-speed or normal mode.
Choose mode depending on your application, if you wish to transmit large
amounts of non critical data, choose high-speed mode with a noise margin 0 dB.
If the data is critical, choose reliable mode.
When choosing one of reliable, high-speed or normal modes, the DDW-100 will
automatically set the highest possible speed according to the noise margin and
distance. The algorithm for sensing highest possible speed may result in a longer
connection time because several attempts have to be done to achieve a connection.
If the connection time is critical, it is possible to discover the connection speed
using the diagnostic port, then set the unit manually according to achieved
speed.
