Introduction

Congratulations on your purchase of a D-Link DI-308 remote access router with
integrated Ethernet switch 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-308 include support for a full range of networking
protocols including TCP/IP (Transmission Control Protocol/Internet Protocol).

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-308 ISDN Remote Router

Product Features

The DI-308 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-308 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
Ethernet switch, and it uses twisted-pair Ethernet cables to connect to the host
network.

Built-in Switch

A dual-speed NWay switch, the DI-308 provides eight ports for connecting network
end nodes—single-user computers, servers, bridges, other routers, etc.—through
standard “straight-through” twisted-pair cables and one port 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-308 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-308 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-308 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-308 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-308 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-308 supports PAP (Password Authentication Protocol) and CHAP
(Challenge Handshake Authentication Protocol).

RIP-1/RIP-2

Your DI-308 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-308 incorporates Stac data compression and CCP (Compression Control
Protocol).

Networking Compatibility

The DI-308 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-308

Some applications for the DI-308 include:

Internet Access

Your DI-308 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-308 ISDN Remote Router

Network Address Translation (NAT)

For small office environments, the DI-308 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-308 can dial to or answer calls from another remote access router connected
to a different LAN. The DI-308 supports TCP/IP and has the capability to bridge any
Ethernet protocol.

Telecommuting Server

The DI-308 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.

What This Manual Covers

This manual is divided into twelve parts.

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-308, 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 stop bit

◊

No flow control

◊

Step 2 - Connecting the Console to the Router

A serial cable is included in the DI-308 package. To connect this cable, plug its nine­pin 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-308. 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 submenu.

• 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 submenu,
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 submenu 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-308 has eight ports for connecting Ethernet devices to form a LAN. The
jacks for ports 1 through 8 are wired to let you connect network end nodes
(computers, servers, bridges, other routers, etc.) using up to 100M of standard
“straight-through” Category 5 UTP cable. In addition, an Uplink jack is wired to let
you connect to another Ethernet or dual-speed switch using a straight-through cable,

Interface

10

DI-308 ISDN Remote Router

or an end node using a cross-wired cable. Please note that when the Uplink port is in
use, Port 1x is unavailable.

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 5 UTP

•

cables with RJ-45 plugs.
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.
This is the maximum signal path in twisted-pair Ethernet. Also be sure never

•

to allow a signal loop to form.

11

DI-308 ISDN Remote Router

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, 2.5A 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-308.

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-308 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

Step 8 - 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:

1. The LAN port must be enabled in the

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
minutes, the router will automatically log you out. Your first endeavor should be to
increase the ‘timeout’ time by adjusting the appropriate value in the
