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 single-user 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
Introduction 1
DI-206 ISDN Remote Router
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—single-user computers, servers,
bridges, other routers, etc.—through standard “straight-through”
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 B-channels can be used independently for two destinations,
or they can be bundled together for one high-bandwidth connection
supporting bandwidth-on-demand.
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.

n
Introductio
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 multilink bundle.
Full Network Management
DI-206 ISDN Remote Router
The DI-206 incorporates SNMP (Simple Network Management
Protocol ) support and menu-driven network management via an RS232 or Telnet connection.
RADIUS (Remote Authentication Dial In User Service)
The RADIUS feature allows you to use a central external Unix or NTbased server to support thousands of users.
PPP Security
The DI-206 supports PAP (Password Authentication Protocol) and
CHAP (Challenge Handshake Authentication Protocol).
Introduction 3
DI-206 ISDN Remote Router
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.
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.
4
n
Introductio
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
DI-206 ISDN Remote Router
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
Installation 13
DI-206 ISDN Remote Router
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.
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
“Configuration and Management” and “Using Telnet” for detailed
instructions on using Telnet to configure your DI-206.
A Warning on Connection Cables
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.
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
14
n
Installatio
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.
DI-206 ISDN Remote Router
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.
Installation 15
DI-206 ISDN Remote Router
♦ Moving Forward to Another Menu To move forward to a
sub-menu below the current one, use <tab> or arrow keys to
position the cursor on the sub-menu 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

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.
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 Interface 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 another
10Mbps Ethernet or dual-speed hub using a straight-through cable, or
an end node using a cross-wired cable.

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.
