Preface
Thank you for placing your trust in this devolo product.
By purchasing the MicroLink ISDN Router or MicroLink dLAN ISDN Router,
you have chosen an ISDN router that innovatively combines the functions and
advantages of an ISDN modem, a switch, a router and a firewall all in a single
device. This combination makes it the optimal, user-friendly network and
Internet access solution for home network solutions and small-office and
home-office (SOHO) environments.
The ISDN modem provides satisfyingly fast Internet access:
With transmission speeds of up to 128 kbps, long waits when down-
loading files, loading Web pages or playing online games are a thing
of the past.
An installation wizard helps you get connected to the Internet quickly.
Access settings for common ISPs are already preconfigured.
It serves as an optimal combination of Internet-access device and net-
work switch:
The router simplifies the installation of Internet access significantly,
as no special drivers are required for the connected individual com
puters. The access protocol has been implemented in the router
itself.
The router functionality lets multiple users access the Internet at the
same time. The firewall function provides protection from hacker
attacks. DHCP automates the TCP/IP configuration of the connected
computers. The router can be configured conveniently using a Web
browser.
The integrated switch is the foundation for small networks. Up to four
computers can be connected simultaneously. Each of the four ports
can also be used as an uplink port to connect additional routers,
switches or hubs.
A HomePlug adapter allows access to the router throughout the building
without having to lay new lines. Instead of network cables, household
power lines are used to transfer data.
Combine your MicroLink ISDN Router together with a devolo Home-
Plug adapter to connect to other network devices via the household
power cables.
If a part of the documentation applies to a certain model only, this is indicated
by a note in the margin.
In the other parts of the documentation, the models are referred to collectively as the MicroLink (dLAN) ISDN Router.

a quick overview of its capabilities.
Simple installation
Connect the computers in the LAN (Ethernet) to the MicroLink (dLAN)
ISDN Router.
Connect the MicroLink (dLAN) ISDN Router to the ISDN connection.
Connect the MicroLink (dLAN) ISDN Router to the power supply grid.
Configure Internet access
That's it!
Versatile networking
Because of the built-in 4-port switch, the PCs connected to the MicroLink
(dLAN) ISDN Router form an internal network with transfer rates of up to
100
Mbps.
The MicroLink dLAN ISDN Router lets you choose how you would like to connect your PCs to the Internet— you can connect them using either the power
supply grid or network cables.
Thanks to the built-in HomePlug technology, the network can be expanded
through household power cables without the need to lay new lines. Each PC
simply needs a MicroLink dLAN connected to an electrical outlet. With dLAN,
you can connect to the Internet, exchange data, share printers or play exciting
multiplayer games from any room of your house. Simply connect the router to
the rest of the dLAN network via the power cable. The four Ethernet ports
remain available for connecting other network devices.
1.2What exactly is dLAN?
There is now a new alternative to the well-known wired LAN and Wireless
LAN network technologies: dLAN (direct LAN, i.e. directly networked). dLAN
is networking using the electric wiring already installed in the building.
dLAN is an especially easy-to-use networking technology. You don't need to
lay cables and you can connect to the network at every power point.
The dLAN standard modulates and demodulates additional frequencies on
the power lines. Modulation and demodulation is a well-known and proven
method of data transmission, which has been in use in other applications for
a number of years. Now it is used to set up Internet and network accesses.
Depending on the attenuation factor, dLAN is capable of covering distances
of at least 200 meters.
With a maximum data transmission rate of 14 Mbps and symmetrical upload
and download, the dLAN standard is equivalent to classical Ethernet net
working solutions and is faster than the wireless standard 802.11b. Depending on the line quality, bandwidths of 6 to 8 Mbps are possible in practice—
quite sufficient for extending the Internet connection.
Data security and radiation
For security reasons, DES
data transfer within the network. In addition, the power meter in the building
can act as a physical barrier against unwanted access from outside.
dLAN devices from devolo meet the stringent EU industrial standards and
comply with the current standards for electromagnetic radiation. Its radiation
level is actually well below that of Wireless LAN technologies.
In this chapter, we will explain the displays and connections of the MicroLink
(dLAN) ISDN Router and show you how to set up the device and connect com

2.2Connecting the MicroLink (dLAN) ISDN Router
Preconditions
Your MicroLink (dLAN) ISDN Router requires a computer running an operating
system with TCP/IP support (e.g. Windows 98, Windows Me, Windows 2000,
Windows XP, MAC OS X, Linux) connected to the MicroLink (dLAN) ISDN
Router via LAN (Ethernet).
To connect a computer to the integrated switch via LAN, use a network cable
with RJ45 plugs, also known as a patch cable. The computer must have a free
LAN port (RJ45).

EN
Connection
햲 Connect the MicroLink (dLAN) ISDN Router to an AC outlet using the AC
adapter. Turn on the power with the switch on the back. The green
'Power' LED on the front panel will light up.
햳 Connect the ISDN cable first to the 'ISDN' socket on your router and then
to the ISDN connection.
햴 Next, use network cables to connect up to four computers to a router's
RJ45 socket (LAN port) respectively and start the connected computers.
The associated 'Link/Act' control lamps light up.
It is important to always start the router before the computers so that the
computers can receive their TCP/IP configuration from the router's DHCP
server while booting.
As each of the RJ45 sockets also functions as an uplink port, you may connect
EN
either a computer or an additional switch (hub) to any of the four ports to link
more than four computers. Thanks to Auto MDI/X, you can use either cross
over or normal cables. An LED labeled 'Link/Act' will be lit on the front panel
for every computer or every network device which is connected and powered
up.
