ISDN Router
User’s Guide

Introduction

Congratulations on your purchase of a D-Link DI-300 series
Remote Access Rout er . I n a modem-sized box, your ro uter offers
ine xpens ive yet comple te telec ommunication s an d inter networ king
solutions for your home or branch office. I t is ideal for everything
from Internet bro wsing to r eceiving calls from Remote Dial-in
Users and making LAN-to - LAN connections to Remote Nodes.

Distinguishing features of the DI-300 series include support for a
full range of networking protocols such as TCP/IP (Transmission
Control Protocol/Internet Protocol, also known as IP), Novell IPX
(Internet P acket Exchange), and Transparent Bridging.

♦ DI-300: ISDN S/T interface, IP routing
♦ DI-300W: ISDN U interface, IP routing
♦ DI-300M: ISDN S/T interface, IP/IPX routing, bridging
♦ DI-300MW: ISDN U interface, IP/IPX r outing, bridging

This complete solution also includes Remote Dial-in User suppor t,
an Internet Single User Account (N etwork Address T r anslation)
opt ion, extensive Network Management, and solid security
features.

2 Introduction

NOTE:

Throughout the remainder of this manual, the term
“DI-300” refers to any DI-300 or DI-300W, and the term
“DI-300M” ref ers t o any D I- 300M or DI- 300MW .

Features

Each DI-300 series router is packed with features that give it the
flex ibility to provid e a comp lete networ king solution for almost an y
user.

Ease of Installation

Your DI-300 or DI-300M is a self-contained unit that is quick and
easy to in stall. Phys ica lly, it resembles an exter n al mod em e x ce pt
for the fact that it is a rout er and uses an Et hernet cable to connect
to the host network.

ISDN Basic Rate Interface (BRI)

Using a standard S/T or U I nt erface (t he DI-300 and DI-300M use
the S/T interface, while the DI-300W and DI-300MW use the U
interface) the DI-300 and DI-300M suppor t a full range of switch
types. The switch type depends on the CO (Centr al Office) switch
your ISDN line is connected to . S ee the

ISDN Switch Types

chapter
for more information on North American, Eu r opean, and Asian
ISDN firmware and swit ch types support ed by these routers.

Introduction 3

The two B- channels can be used independently fo r two
destinations. Or they can be bundled fo r one connection to suppor t
bandwidth-on-demand.

ISDN Leased Line

If the router is set up for an ISDN leased line (t hat is, if any opt ion
but Switch/Switch or Switch/Unused is selected for the B Channel
Usage control in setup menu 2, “ISDN Setup, ” and the Tr ansfer
Type control is set to Leased in either setup menu 4, “Internet
Access Setup,” or set up menu 11.1, “Remote Node Profile”), the
route r will automatically initialize th e le ased -line c on nection each
time it is po wer ed up or setup menu 2, 4, or 11. 1 is saved.

The DI-300 and DI-300M implement the PPP echo mechanism for
verifying ISDN leased line status. The setting of the Idle Timeout
con trol in setup menu 11.1 will be u sed a s the interval between t wo
LCP_Echo_Req messages. It is supposed that t here exists an echo
reply correspo nding to an echo request. Whenever an echo request
is sen t, the counter will be increme nt ed by one .

T h e s end counter will be r eset to zero after an ech o response is
received. The leased- line error reco very mechanism will be
triggered after the send counter r eaches 4. If the Idle Timeout
control is set to zero, the PPP echo mechanism will no t b e u se d.

Multiple Networking Protocol Support

The DI-300M is a multi-proto col router. It supports T CP/IP,
Novell I PX, and Transparent Bridging.

4 Introduction

Dial On Demand

The Dial On Demand feature allows a DI-300 or DI - 300M t o
auto matically place a call to a Remote Node whenever there is
traffic coming fro m any workstation on the LAN to that remote
site.

Bandwidth On Demand

Your DI-300 or DI-300M supports bandwidth up to 128 Kbps over
a single ISDN BRI line. It incorporates PPP/MP (Point-to -Point
Protoc ol/Multilink P rotoc ol) to bundle two B channels ov er a BRI
line. In addition, the router dynamically allocates bandwidth
between the two B channels, increasing or decreasing bandwidt h as
needed to allow for greater efficiency in data t r ansfer. It suppo r ts
BAP (Bandwidth Allo cation Prot ocol) and BACP (Bandwidth
Alloc ation C ont rol Pr otocol) to manage the numbe r of links in
multilin k bundle.

Full Network Management

The DI-300M incorporates SNMP (Simple Net work Management
Prot ocol) support and menu-driven network management via an
RS-232 or T elnet connection. In addition, both the DI-300 and the
DI-300M offer the Call Detail Record ( CDR) function to help you
an alyz e a nd manage you r telephon e bill.

RADIUS (Remote Authentication Dial In User Service)

The RADIUS feature allows you to use a cent r al external Unix­based server to suppo r t thousands of users (DI-300M only).

Introduction 5

PPP Security

The DI-300 and DI-300M support PAP (Password Aut hentication
Protoco l) and CHAP (Challenge Handshake Authentication
Protocol).

MS (Microsoft) CHAP

Your DI-300 or DI-300M and a Microsoft Windows 95 o r
Windows NT server can authenticate each other using Microsoft’s
proprietary CHAP algorithm. No special setup is needed to suppor t
MS CHAP. Everything is done through PPP negotiation between
the router and the server.

RIP-1/RIP-2

Your DI-300 or DI-300M support s bot h RIP-1 and RIP-2 (Routing
Information Pro toco l versions 1 and 2) exchanges with other
rout ers. RIP version controls in setup menus 3.2 (TCP/IP and
DHCP Ethernet Setup) and 11.3 (Remote Node Networ k Layer
Options ) le t you con trol R IP use, and offer th e following v er sion
opt ions: RIP- 1 ( accept and send RIP-1 messages only), RIP-2B
(accept RI P-1 and RIP-2 messages, both broadcast and multicast,
and send RIP-2 messages in broadcast format), and RIP-2M
(accept RI P-1 and RIP-2 messages, both broadcast and multicast,
an d send RIP-2 me ssages in multicast format) .

(The suggested choice in bot h menus is RIP-2B, except in
envir onments where there are r outers that do not understand RIP-2
packets at all. “Broadcast, ” abo ve, means a destination MAC or IP
host addr ess consisting of all binary ones; “multicast” means a

6 Introduction

MAC address of 01:00:5E:00:00:09 hex or an IP destination
address of 224.0.0.9.)

DHCP Support (Dynamic Host Configuration Protocol)

DHCP (D yn amic Hos t Configuration Protocol) allows you to
dynamically and automatically assign IP addr ess settings to hosts on
your network.

Call Control

Your DI-300 or DI-300M pro vides budget management for
out going calls and maintains a “blacklist” of unreachable phone
number s in order to save you the expense of unnecessary charges.

Data Compression

The DI-300 and DI-300M incorporate St ac data compression and
CCP (Compression Control Protocol).

Networking Compatibility

The DI-300 and DI-300M are 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.

Introduction 7

Applications For Your DI-300 or DI-300M

Some applications for the DI-300 and DI-300M include:

Internet Access

Your DI-300 or DI-300M supports the TCP/IP protocol, which is
the language used for the Inter net . I t is also compatible with access
servers manufactured by major vendors such as Cisco and Ascend.

Internet Single User Account (SUA)

For small office environments, the DI-300 and DI-300M offer a
Single User Int er net Account ( also known as a Netwo r k Address
Translator, or NAT) from an ISP (Internet S er vice Provider). This
allows multiple user s on the LAN (Local Area Network) t o access
the Inter net concurrently for the co st of a single user.

Single User Acco unt addr ess mapping can also be used for LAN to
LAN connections.

Multiprotocol LAN-to-LAN Connection

The DI-300 and DI-300M can dial to or answer calls from anot her
remote access ro uter connected t o a different network. The
DI-300M support s TCP/IP and Novell IPX, and has the capability
to bridge any Ethernet protocol.

8 Introduction

Telecommuting Serve r

The DI-300 and DI-300M allow Remot e 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 ., Win dow s 95, to
dial in using an ISDN terminal adapter (TA) to access the netwo r k
resources without physically being in the office.

14 Before You Begin

Collecting General Setup Information

Your DI-300 or DI-300M requires the following system
information. Yo u c an obtain all the pe rtinent informa tion from you r
networ k administrato r . Record this information int o the wor ksheet
as it be comes av aila b le. This worksheet will later be r efe rred to as
you configure your router.

♦ System Name—T his is the name g iven to the router for

identification purposes . This name sh ould be n o more than 8
alphanumeric characters. Spaces ar e no t allowed, but “-” and
“_” are accepted. This name can be obtained remot ely via the
SNMP mana ge ment pr otocol an d w ill be displa yed as the
prompt when t he user enters Command Interpreter Mode.

♦ Route IP Field—For Int er net access, you will need to ena ble

the Rout e I P Field. See the

Configuring for Internet A ccess

chapter starting on page 38 for more details on configur ing
your rout er for Int er net access. T o support Novell IPX, or
Bridging, enable the appropriate pro toco l and reference the
related chapters for de tailed information.

You have now collected all of the general setup information you
need. Make sure that you have entered all the values onto t he
worksheet before proceeding to the next section.

Collecting ISDN Phone Line Information

Afte r you ha ve successfu lly installed the ISDN phone line or if you
already have one installed, you need to use the ISDN line
information to complete the worksheet and co nfigure your router.

Before You Begin 15

Your t elephone company can give you the following information to
configure the DI-300 or DI- 300M:

Switch Type Geography No. of Phone #s No. of SPIDs

AT&T 5ESS NI-1 North America 2 2
AT&T 5ESS Point to Point North America 1 0
AT&T 5ESS Multipoint North America 2 2
Northern Telecom NI-1 North America 2 2
Northern Telecom Custom North Am erica 2 2
DSS1 Europe, Asia 2 N/A
1TR6 Germany 2 N/A

♦ Switch Type—This is the type of switch used by your

telephone company. Check wit h your t elephone company and
choose t he appropriate option on the worksheet. For North
America, select your ISDN switch type. For DSS 1 and 1TR6,
verify this field to make sure that you have the proper
firmware loaded.

♦ B Channel Usage—De ter mine which c on nection is

appropriate for your B channel and check the corresponding
option on the worksheet.

If your DI-300 or DI - 300M is the only device using the ISDN

line, configure B Channel Usage to Switch/Switch so the router
device will u se bo th B cha nne ls to communicate. If th e r oute r is
sharing the ISDN line with other devices, configure B Channel
Usage to Switch/Unused. If your DI-300 or DI - 300M is on a
leased line, configure B channel usage t o Leased/Leased or
Leased/Switch, depending on the setting of the line.

♦ Telephone Number(s)—Record on the worksheet the

telephone number ( s) given to you by your ISDN provider.
Some switc h type s only have one tele phone number . These
phone numbers should be in a standard digit format (for
example, 5551212). Note that these fields will only accept
digits, so—and spaces will not b e accepted.

16 Before You Begin

♦ SPID Number(s)—(For North Amer ica only) The SPID

(Service Profile Ident ifier) is a number used by a central
office switch for identification purposes. With the switch
information, see the previous table for the number of SPIDs
you must enter .

You have now collected all of the necessary information about your
ISDN phone line. Make sure that these values are entered into your
worksheet before you cont inue to the next section. For DSS1 and
1TR6 ISDN, refer to the

Installation

chapter starting on page 21.

Collecting Ethernet Setup Information

This section assumes that you are setting up your router for a
TCP/IP connection. If you want to configur e the system for other
protocols (e.g., IPX), refer to t he appropriate chapters.

♦ Ethern et I nte rf ace —Your DI-300 or DI - 300M is equipped

with an NWay auto-sensing 10/100- Mbps port. Just plug in
the ca b le, an d the r oute r will automatically de termine th e
network speed (10 Mbps or 100 Mbps) and mode (full or half
duplex) based on the capability and con figuration of the
att ached device.

♦ IP Address—An IP Address is required for TCP/IP prot ocol.

The IP Address is a unique 32- bit number assigned to your
route r. I t is w ritte n in d otted decimal nota tion (four 8-bit
numbers, between 0 and 255, separated by per iods), e.g.,

192.68.203.5.

Record the IP Address into the worksheet as assigned by your

network administr ator. Note t hat every machine on a TCP/IP

Before You Begin 17

network ( the global Internet, for example) must have a unique
IP address; do no t assign an arbitrar y address to any machine.

♦ IP Sub-net Mask—This field is required for TCP/IP

protocol. An IP address consists of two parts, the network ID
and the host ID. The IP Subnet Mask is used to specify the
network ID portion of the address, expressed in dot ted
decimal notation. Your DI -300 or DI-300M will
auto matically calculate this mask based on t he IP addr ess that
you assign. Unle ss you have special need for subnetting, use
the default mask as calculated by the router .

The table belo w lists some examples of IP subnet masks and the
number of hosts that are allo wed. Consult your network
administ rator if you a re unsure of this v alu e.

IP Subnet Mask Number of Host IDs Number of Bits
