Introduction 1
NOTE:
Throughout the remainder of this manual, the term
“DI-300” refers to any DI-300 or DI-300W, and the term
“DI-300M” refers to any DI- 300M or D I- 300MW .
Features
Each DI-300 series router is packed with features that give it the
flexibility 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 install. Phys ica lly, it resembles an exter n al mod em e xcept
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 o r 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 support a full range of switch
types. The switch type depends on the CO (Central Office) switch
your ISDN line is connected to. See t he
ISDN Switch Types
for more information on North American, European, and Asian
ISDN firmware and switch types supported by these routers.
2 Introduction
chapter
The two B- channels can be used independently for t wo
destinations. Or they can be bundled for one connection to suppor t
bandwidth-on-demand.
ISDN Leased Line
If the router is set up for an ISDN leased line (that is, if any option
but Switch/Switch or Switch/Unused is selected for t he B Channel
Usage contro l in setup menu 2, “ISDN Setup,” and the Transfer
Type control is set to Leased in either set up menu 4, “Internet
Access Setup,” or setup menu 11.1, “Remote Node Profile”), the
router will automatically initialize th e le ased -line c on nection each
time it is powered 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
control in setup menu 11.1 will be u sed a s the interv al between t wo
LCP_Echo_Req messages. It is supposed that there exists an echo
reply corr esponding to an echo request. Whenever an echo request
is s ent, the counter will be increme nt ed by one .
Th e s end counter will be r eset to zero after an ech o respons e is
received. The leased-line error recovery 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 not be u sed.
Multiple Networking Protocol Support
The DI-300M is a multi-protocol rout er . I t support s TCP/IP,
Novell IPX, and Transparent Bridging.
Introduction 3
Dial On Demand
The Dial On Demand feature allows a DI-300 or DI - 300M t o
automatically place a call to a Remote Node whenever there is
traffic coming from any workstation on the LAN to that remote
site.
Bandwidth On Demand
Your DI-300 or DI-300M support s bandwidth up to 128 Kbps over
a single ISDN BRI line. It incorporates PPP/MP (Point-to-Point
Protocol/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 bandwidth as
needed to allow for greater efficiency in data t r ansfer. It suppo r ts
BAP (Bandwidth Allocation Proto col) and BACP (Bandwidth
Allocation C ont rol Pr otocol) to manage the numbe r of links in
multilink bundle.
Full Network Management
The DI-300M incorporates SNMP (Simple Networ k Management
Protocol) support and menu-driven network management via an
RS-232 or Telnet connection. In addition, both the DI-300 and the
DI-300M offer the Call Detail Record (CDR) function to help you
analyz e a nd manage you r telephon e bill.
RADIUS (Remote Authentication Dial In User Service)
The RADIUS feature allows you to use a central external Unixbased server to support t ho usands of users (DI-300M only).
4 Introduction
PPP Security
The DI-300 and DI-300M support PAP (Password Authentication
Protocol) and CHAP (Challenge Handshake Authentication
Protocol).
MS (Microsoft) CHAP
Your DI-300 or DI-300M and a Microsoft Windows 95 or
Windows NT ser ver can authenticate each other using Microsoft’s
proprietary CHAP algorithm. No special setup is needed to support
MS CHAP. Everything is done through PPP negotiation between
the router and the server.
RIP-1/RIP-2
Your DI-300 o r DI- 300M suppor ts both RIP-1 and RIP-2 (Routing
Information Protocol versions 1 and 2) exchanges with other
router s. RIP version controls in setup menus 3.2 (TCP/IP and
DHCP Ethernet Setup) and 11.3 (Remote Node Networ k Layer
Optio ns) let you cont rol R IP use, and offer th e following v er sion
options: RIP- 1 ( accept and send RIP-1 messages only), RIP-2B
(accept RIP - 1 and RIP- 2 messages, bot h bro adcast and multicast,
and send RIP-2 messages in broadcast format), and RIP-2M
(accept RIP - 1 and RIP- 2 messages, bot h bro adcast and multicast,
and send RIP-2 me ssages in multicast format) .
(The suggested choice in both menus is RIP-2B, except in
environments where there are ro uters that do not underst and RIP - 2
packets at all. “Broadcast, ” abo ve, means a destination MAC or IP
host address consisting of all binary ones; “multicast” means a
Introduction 5
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 (Dynamic Host Con f igu ration Pr otocol) allows you to
dynamically and automatically assign IP address settings to hosts on
your network.
Call Control
Your DI-300 or DI-300M provides budget management for
outgoing calls and maintains a “blacklist” of unreachable phone
numbers 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
product s from other companies such as Ascend, Cisco, and 3Co m.
Furthermore, they support Microsoft Windows 95 and Windows
NT remote access capability.
6 Introduction
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 support s the TCP/IP prot ocol, which is
the language used for t he Int er 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 Internet Account ( also known as a Network Address
Translator, or NAT) from an ISP (Internet S er vice Provider). This
allows multiple users on the LAN (Local Area Network) to access
the Internet concurrently for the cost of a single user.
Single User Account address 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 another
remote access router connected t o a different network. T he
DI-300M supports TCP/I P and Novell IPX, and has the capability
to bridge any Ethernet protocol.
Introduction 7
Telecommuting Server
The DI-300 and DI-300M allow 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., Window s 95, to
dial in using an ISDN terminal adapter (TA) to access the netwo r k
resources without physically being in the office.

Collecting General Setup Information
Your DI-300 or DI-300M requires the following system
infor mation. You can obtain all the pe rtinent informa tion from you r
network administrat or. Reco r d this information into t he worksheet
as it b ec omes available. T h is workshee t will later be re fer red to as
you configure your router .
♦ System Name—This is the na me g iven to the router for
identific ation purposes. This name sh ould be n o more than 8
alphanumeric characters. Spaces are not allowed, but “-” and
“_” are accepted. This name can be obtained remotely via the
SNMP ma nagement pr otocol an d w ill be displa yed as the
prompt when the user enters Command Interpreter Mode.
♦ Route IP Field—For Inter net access, you will need to enable
the Rout e I P Field. See the
chapter start ing on page 38 for more details on configuring
your router for I nter net access. T o support Novell IPX, or
Bridging, enable the approp r iate protocol and reference the
related chapters for de tailed information.
Configuring f o r I nt ernet Access
You have now collected all of the general setup information you
need. Make sure that you have entered all the values onto the
worksheet before proceeding to the next section.
Collecting ISDN Phone Line Information
After 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.
14 Before You Begin
Your telephone company can give you the following information to
configure the DI-300 or DI - 300M:
Switch Type Geography No. of Ph one #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 America 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 with your telephone company and
choose the appropriate option on the worksheet. For North
America, select your ISDN switch type. For DSS1 and 1TR6,
verify this field to make sure that you have the proper
firmware loaded.
♦ B Channel Usage—Deter mine which c on nection is
appropriate for your B channel and check the correspo nding
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
devic e w ill us e both B chan nels to commu nicate. If the route r is
sharing the ISDN line with ot her devices, configure B Channel
Usage to Switch/Unused. If your DI-300 or DI-300M is on a
leased line, configure B channel usage to Leased/ Leased or
Leased/Switch, depending on the setting of the line.
♦ Telephone Number(s)—Record o n t he wo r ksheet the
telephone number(s) given to you by your ISDN provider.
Some switch type s only have one tele phone number . These
phone numbers should be in a standard digit format (for
example, 5551212). Not e that these fields will on ly accept
digits, so —and spaces will n ot b e accepted.
Before You Begin 15
♦ SPID Number(s)—(For North America only) The SPID
(Service Profile Identifier) 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
yo u mu st e nter.
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
Collecting Ethernet Setup Information
This section assumes that you are set ting up your router for a
TCP/IP connection. If you want t o configure the system for other
protocols (e.g., IPX), refer to the appropriate chapters.
♦ Ethernet I nte rface—Your DI-300 or DI-300M is equipped
with an NWay auto-sensing 10/100-Mbps port. Just plug in
t he cab 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 configuration of th e
attached device.
chapter start ing on page 21.
♦ IP Address—An IP Address is required for TCP/IP protoco l.
The IP Address is a unique 32-bit number assigned to your
router. I t is w ritte n in d otted de cimal not ation (fou r 8- bit
numbers, between 0 and 255, separated by periods), e.g.,
192.68.203.5.
Record t he IP Address into t he wo r k sheet as assigned by your
network administrator. Note that every machine on a TCP/IP
16 Before You Begin
network (the global Internet, for example) must have a unique
IP address; do not assign an arbitrary 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 po rtion of the address, expressed in dotted
decimal notation. Your DI-300 or DI - 300M will
automatically calculate this mask based on the IP address that
you assign. Unless you have special need for subnetting, use
the default mask as calculated by the router.
The table below lists some examples of IP subnet masks and the
number of hosts that are allowed. Consult your network
adminis tra tor if you are unsure of this valu e.
IP Subnet Mask Number of Host IDs Number of Bits

chap ter for detailed ins tructions on
using Telnet to configure your DI-300 or DI-300M.
Connecting the RS-232 Cable to the Router
An RS-232 cable is included in your package. To connect this
cable, connect the 9-pin end of the cable to the DCE port on the
rout er ’s back panel. Connect the other end to the RS-232 cable
connected to the serial port (COM1, COM2, or any other COM
port) of your co mputer.
Connecting an ISDN Line to the Router
Telnet
Plug one end of your ISDN phone line into the socket on the rear
panel of the router labeled ISDN and the other end into the ISDN
