Description
Functional description
The DDW-120 Ethernet Extender is the ideal solution for extending your Ethernet
network over copper cables where in the past the only option would have been fibre.
At shorter range the transfer rate will be as fast as 15.3 Mbit/s in both directions.
Depending on the quality of the cables distances up to 15 km are possible.
DDW-120 is transparent for multicast addressing, VLAN packets, VPN pass-through for
IPSec and for protocols like MODBUS/tcp and Profinet. The Link Fault Forward (LFF)
functionality in DDW-120 forwards information about the Ethernet link status, this is
sent over the SHDSL link between two DDW-120 units. In many applications it is a
requirement to disconnect the link on the other side of the SHDSL link if the primary
Ethernet link goes down.
The units will auto negotiate the transmission speed but can also be forced to choose a
slower (more reliable) or faster (less reliable) data rate.
Communication speed and distance depends on the cable characteristics, communication
reach with different cables can be calculated with DDW-tool
DDW-120 can be used in point-to-point applications or as start and termination unit
together with other Wolverine products in daisy-chain applications.
Description of used nomenclature:
Noise margin:
The margin between signal and noise (dB)
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.

8
6621-2214
Getting started
The DDW-120 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-120.
 Connect the SHDSL Line
1) Connect the twisted pair to DSL screw terminal 1 and 2 (polarity independent)
situated at the base of the DDW-120.
 Connect the Ethernet Line
Connect Ethernet to the TX port on the front of the DDW-120.
The factory settings for the DDW-120 is plug and play mode where TX port is enabled
for:
… Ethernet Auto-negotiation enabled.
… Auto MDI/MDI-X.
… Auto-polarity enabled.
The DDW-120 will automatically sense the data rate of the connected unit and cable
type.
 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-120 is as CPE.
Depending on the quality of the line and the distance there is possibility to select
autobaud function.
This is done via DIP switches in the unit configured as CO. Factory default is autobaud,
reliable mode.
Note! Before connection and installation one of the connecting units have to be
reconfigured as a CO, see DIP-switch S1:4.
Note!
If the DSL link is not established, the speed might be set to high for the distance.

Diagnostic information
The DDW-120 can display diagnostic information on two way:
1) Using the Westermo diagnostic tool DDWtool.exe.
2) Using a terminal program.
Using DDW-tool
1) Connect the standard cable 1211-2027 to the diagnostic port, located under the lid of
DDW-120.
2) Choose the corresponding Com port in the drop list of the tool. The tool will try to
find the port used by the debug cable.
3) Click the button connect, if the correct com port is selected DDW-tool will be
updated with actual status online information.
Information from diagnostic tool
• Software release
• Serial number
• DIP switch settings
• If the unit is configured as CO or CPE
• Ethernet link status

If a customer supervision system is used the DDW-120 can provide with diagnostic
status.
The DDW-120 support
Data rate: 115.2 kbit/s
Data bits: 8
Stop bits: 1
Parity: None
Flow control: None
The unit is responing to two commandon
1) DIAG
2) RUNDIAG
Information from DIAG command
• Software release
• DIP switch settings
• If the unit is configured as CO or CPE
• If the unit is configured for Annex A or Annex B
• DSL link state
• DSL data rate (bit/s)
• DSL noise margin (dB)
• Ethetnet data rate
• Ethernet duplex
Information from RUNDIAG command
• DSL link state
• DSL Data rate (bit/s)
• DSL Noise margin (dB)
The DDW-120 is ready for commando then prompt “DDW” is transmitted to supervisor
system.
The commando RUNDIAG will continuously send the information. Approx update with
1s base. Commando is aborted by sending “any key to abort”.

* 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.
