Introduction
Congratulations on your purchase of a D-Link DI-206 series remote access router
with integrated Ethernet hub and ISDN T/A. No larger than an ordinary modem,
your router offers inexpensive yet complete telecommunications and internetworking
solutions for your home or branch office. It is ideal for everything from Internet
browsing to receiving calls from Remote Dial-in Users and making connections to
other LANs via Remote Nodes.
Distinguishing features of the DI-206 include support for a full range of networking
protocols, including TCP/IP (Transmission Control Protocol/Internet Protocol, also
known as IP).
This complete solution also includes remote dial-in user support, an Internet singleuser account (Network Address Translation) option, extensive network management
capabilities, and solid security features.
DI-206 ISDN Remote Router
Product Features
The DI-206 router is packed with features that give it the flexibility to provide a
complete networking solution for almost any small to medium-sized office
environment.
Ease of Installation
Your DI-206 is a self-contained unit that is quick and easy to install. Physically, it
resembles an external modem; however, it is a combination ISDN router and 10
Mbps Ethernet hub, and it uses twisted-pair Ethernet cables to connect to the host
network.
Built-in Hub
As a 10 Mbps Ethernet hub, your DI-206 provides six ports for connecting standard
Ethernet devices. Five ports are designed for connecting network end nodes—singleuser computers, servers, bridges, other routers, etc.—through standard “straightthrough” twisted-pair cables; the sixth is wired for making an “uplink” connection to
another hub or switch through the same type of straight-through cable used to
connect end nodes.
ISDN Basic Rate Interface (BRI)
Using a standard S/T the DI-206 supports DSS1 ISDN switches. The two ISDN Bchannels can be used independently for two destinations, or they can be bundled
together for one high-bandwidth connection supporting bandwidth-on-demand.
1
DI-206 ISDN Remote Router
ISDN Leased Line
If the router is set up for an ISDN leased line, it can automatically initialize the
leased-line connection each time it is powered up.
Standard Phone Jacks
The router is equipped with two standard phone jacks for connecting telephones, fax
machines, or modems. This allows the ISDN line to be used for voice as well as data
calls.
Dial On Demand
The Dial On Demand feature allows a DI-206 to automatically place a call to a
Remote Node whenever there is traffic coming from any workstation on the LAN
(Local Area Network) to that remote site.
Bandwidth On Demand
Your DI-206 supports bandwidth up to 128 kbps over a single ISDN BRI line. It
incorporates MLPPP (Multi-Link PPP) to bundle two B channels over a BRI line. In
addition, the router dynamically allocates bandwidth between the two B channels,
increasing or decreasing bandwidth as needed to allow for greater efficiency in data
transfer. It supports BAP (Bandwidth Allocation Protocol) and BACP (Bandwidth
Allocation Control Protocol) to manage the number of links in the multi-link bundle.
Full Network Management
The DI-206 incorporates SNMP (Simple Network Management Protocol) support
and menu-driven network management via an RS-232 or Telnet connection.
RADIUS (Remote Authentication Dial In User Service)
The RADIUS feature allows you to use a central external Unix or NT-based server
to support thousands of users.
PPP Security
The DI-206 supports PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol).
RIP-1/RIP-2
Your DI-206 supports both RIP-1 and RIP-2 (Routing Information Protocol versions
1 and 2) exchanges with other routers.
DHCP Support (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) allows IP addresses to be
automatically and dynamically assigned to hosts on your network.
2
Data Compression
The DI-206 incorporates Stac data compression and CCP (Compression Control
Protocol).
Networking Compatibility
The DI-206 is compatible with remote access products from other companies such as
Ascend, Cisco, and 3Com. Furthermore, they support Microsoft Windows 95 and
Windows NT remote access capability.
Applications for your DI-206
Some applications for the DI-206 include:
Internet Access
Your DI-206 supports TCP/IP protocol, which is the language used for the Internet.
It is also compatible with access servers manufactured by major vendors such as
Cisco and Ascend.
DI-206 ISDN Remote Router
Network Address Translation (NAT)
For small office environments, the DI-206 allows multiple users on the LAN to
access the Internet concurrently through a single Internet account. This provides
Internet access to everyone in the office for the price of a single user.
NAT address mapping can also be used to link two IP domains via a LAN-to-LAN
connection.
LAN-to-LAN Enterprise Connections
The DI-206 can dial to or answer calls from another remote access router connected
to a different LAN. The DI-206 supports TCP/IP and has the capability to bridge any
Ethernet protocol.
Telecommuting Server
The DI-206 allows Remote Dial-in Users to dial in and gain access to your LAN.
This feature enables users that have workstations with remote access capabilities,
e.g., Windows 95, to dial in using an ISDN terminal adapter (TA) to access the
network resources without physically being in the office.

Installation and Initial Configuration
This section discusses the different connections that can be made to the router when
setting it up.
Initially, you will only wish to connect the console to the router in order to configure
the other ports. Once that is complete, you will need to turn off the power to the
router and plug in the connection cables to the other devices. Next, power on the
other devices. When they have finished powering up, power on the router. Each of
these steps is described in detail in the sections below. Please skip any setting
adjustments that do not apply to your configuration needs.
8
For the initial configuration of your DI-206, you must use an RS-232 console
connection, either to a computer running serial communications software or to a
serial data terminal.
After the router has been successfully installed and the initial configuration is
complete, you can continue to modify settings through the console, or you can
change configuration settings through a remote Telnet connection or through a web
browser. See the chapters entitled “
Telnet”

ISDN and Ethernet cables are very similar to each other. It is important that you use
the correct cable for each connection; otherwise, your router could be damaged.
Before connecting or disconnecting an RS-232 cable between two devices, turn both
devices off to avoid any chance of damaging them.

Using
Step 1 - Setting up the Console
The initial setup of the DI-206, requires connecting a console to the 9-pin RS-232
Diagnostic port on the router’s rear panel. A serial cable is supplied with the
router in order to make this connection. A console can be a terminal, such as a
VT-100, or a normal PC running terminal emulation software (such as Microsoft
HyperTerminal, included with Windows). The terminal emulation software needs
to be configured to the following parameters:
VT100 terminal emulation
◊
9600 baud
◊
No parity, 8 data bits, 1 start bit, 1 stop bit
◊
No flow control
◊
Step 2 - Connecting the Console to the Router
A serial cable is included in the DI-206 package. To connect this cable, plug its
nine-pin connector into the 9-pin RS-232 Diagnostic port on the router’s rear panel,
then connect the other end to the serial port on the rear of your computer or data
terminal.
Please make sure both machines are turned off before making this connection.
After the connection is made, first power on the console. If you are using a PC, run
the terminal emulation software at this time. After the PC and the terminal emulation
software are up and running, power on the router.

Using the Console
The Console Program is the interface that you will be using to configure your DI-
206. Several operations that you should be familiar with before you attempt to
modify the configuration of your router are listed below:
♦ Moving the Cursor
Within a menu, use <tab> and arrow keys to navigate
through different information fields.
♦ Moving Forward to Another Menu
the current one, use <tab> or arrow keys to position the cursor on the submenu item and press <Enter> to view the selected sub-menu.
♦ Entering Information
There are two types of fields that you will need to fill
in. The first requires you to type in the appropriate information. The second
gives you choices to choose from. In the second case, press the space bar to
cycle through the available choices. Upon configuring all fields the sub-menu,
position the cursor on SAVE and press <Enter> to save, or position the cursor
on EXIT to cancel.
♦ Refresh Screen
Console screens are notorious for becoming garbled. When
this happens, simply press <Ctrl> + <R> to refresh the contents of the screen.
Step 3 - Connecting an ISDN Line to the Router
Your phone company will provide an S/T interface into your home or office. Plug
the ISDN line from the router directly into the ISDN wall socket provided by your
phone company.
To move forward to a sub-menu below
Step 4 - Connecting a Telephone or Fax Machine to the Router
You can connect a regular telephone, fax machine, or modem to your router to be
used for analog calls. Note that the router’s other functions all work the same
whether you connect an analog device or not.
To connect an analog device, just plug one end of the device’s cord into one of the
sockets on the back of the router marked PHONE 1 or PHONE 2.
To have incoming calls directed to a device on a PHONE jack, you must enter the
telephone number for the phone in the console program under the
Configuration, ISDN
submenu.
Step 5 - Connecting Ethernet Cables to the Router
Your DI-206 has six ports for connecting 10BASE-T Ethernet devices to form a
LAN. The jacks for ports 1 through 5 are wired to let you connect network end nodes
(computers, servers, bridges, other routers, etc.) using standard “straight-through”
EIA (Electronic Industries Association) Category 3 or higher twisted-pair cables.
The jack for the sixth port is labeled Uplink and is wired to let you connect to
Interface
10
DI-206 ISDN Remote Router
another 10Mbps Ethernet or dual-speed hub using a straight-through cable, or an end
node using a cross-wired cable.
Please refer to the following chart when deciding on the type of cable necessary for a
given connection:

The figure below shows how to make an Ethernet connection between the router and
a network end node.
Important Notes on Ethernet Connections
Observe the following rules when connecting devices with twisted-pair Ethernet
cables:
For both end-node and uplink connections, use only EIA Category 3 or higher-
•
grade twisted-pair data cables with RJ-45 plugs. In almost all cases, only
standard straight-through cables are needed.
Make sure no cable is more than 100 meters (328 feet) long.
•
When uplinking two hubs together with a straight-through cable, use an
•
uplink-type jack at one end, and an end-node-type jack at the other.
If uplinking more than two hubs together, observe the 5-4-3 rule: no signal, in
•
order to go from one end node to another, must ever pass through more than
five twisted-pair cables, four repeaters (that is, hubs), and three uplink cables.
11
DI-206 ISDN Remote Router
This is the maximum signal path in twisted-pair Ethernet. Also be sure never
to allow a signal loop to form.
Note that you can connect an end node through the Uplink jack, but to do so
you must use a cross-wired cable or cable converter.
Step 6 - Powering Up Devices for Initial Configuration
Plug in the included 18V DC, 750 mA power adapter into the power jack on the
router’s rear panel.
You should have now connected the RS-232 cable to the console, the ISDN phone
line, one or more Ethernet cables, and the power adapter.
At this point in the installation process you can now power up the console computer,
run the terminal emulation software (if necessary), and then power up the DI-206.
Step 7 - Initial Configuration of the Router
After the console is properly connected and both devices are powered on as
described in the preceding sections, you should see the router run through the power
on self test (POST). Finally, it will arrive at the logon screen shown below. If the
login screen does not appear, press <Ctrl> + <R> to refresh the screen.
12
DI-206 ISDN Remote Router
To log on to the router, use the factory set username and password “Admin”
(without the quotes). Please note that the user name and password are case-sensitive.
Upon entering the username and password (using the <tab> key to jump to the next
field), position the cursor on OK and press <Enter>. You will then see the following
Main Menu
:
Step 7 - Configuring the LAN Port
Preparing the router for connection to a LAN only requires enabling the LAN port,
enabling IP networking, assigning the LAN port an IP address and enabling Telnet
(if necessary). After the LAN port is configured, all other features on the router can
be configured remotely through the LAN by using the included Windows-based
Router Configuration Utility or Telnet. Regardless, the router can always be
configured using a console connected to the RS-232 Console port.
To configure the LAN:

Configuration and Management
After the initial startup (POST) test, the router will prompt you for login and
password. This is the opening page of the router’s out-of-band configuration
program, called the Console program. The Console program is stored in the Flash
memory chips in the router and the settings are written in EEPROM chips in the
router. It is the most basic level for configuring and managing the router and the
network to which it is connected.
If you’re starting the router for the first time, the default login and password is
“Admin” – the login and password are case-sensitive, alphanumeric characters.
Note that once you are in the
