extensive Network Management, and solid security features.
NOTE: Throughout the remainder of this manual, the term “IRT-
1001”refers to any IRT-1001ST or IRT-1001U, and the
term “IRT-1002”refers to any IRT-1002ST or IRT-1002U.
Features
Each IRT-1000 series router is packed with features that give it the
flexibility to provide a complete networking solution for almost any user.

PLANET ISDN Router
2
Ease of Installation
Your IRT-1001 or IRT-1002 is a self-contained unit that is quick and
easy to install. Physically, it resembles an external modem except for
the fact that it is a router and uses an Ethernet cable to connect to the
host network.
ISDN Basic Rate Interface (BRI)
Using a standard S/T or U Interface (the IRT-1001ST and IRT-1002ST
use the S/T interface, while the IRT-1001U and IRT-1002U use the U
interface) the IRT-1001ST and IRT-1002ST support a full range of
switch types. The switch type depends on the CO (Central Office) switch
your ISDN line is connected to. See the ISDN Switch Types chapter for
more information on North American, European, and Asian ISDN
firmware and switch types supported by these routers.
The two B-channels can be used independently for two destinations. Or
they can be bundled for one connection to support 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 the B Channel [Usage
control] in setup menu 2, [ISDN Setup], and the [Transfer Type control]
is set to Leased in either setup menu 4, [Internet Access Setup], or
setup menu 11.1, [Remote Node Profile]), the router will automatically
initialize the leased-line connection each time it is powered up or setup
menu 2, 4, or 11.1 is saved.
The IRT-1001ST and IRT-1002ST 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 used as the interval between two
LCP_Echo_Req messages. It is supposed that there exists an echo
reply corresponding to an echo request. Whenever an echo request is
sent, the counter will be incremented by one.

IRT-1000 series User's Guide 3
The send counter will be reset to zero after an echo response is
received. The leased-line error recovery mechanism will be triggered
after the send counter reaches 4. If the Idle Timeout control is set to
zero, the PPP echo mechanism will not be used.
Multiple Networking Protocol Support
The IRT-1002 is a multi-protocol router. It supports TCP/IP, Novell IPX,
and Transparent Bridging.
Dial On Demand
The Dial On Demand feature allows a IRT-1001 or IRT-1002 to
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 IRT-1001 or IRT-1002 supports bandwidth up to 128 Kbps over a
single ISDN BRI line. It incorporates PPP/MP (Point-to-Point
Protocol/Multilink Protocol) 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 multilink bundle.
Full Network Management
The IRT-1002ST incorporates SNMP (Simple Network Management
Protocol) support and menu-driven network management via an RS-232
or Telnet connection. In addition, both the IRT-1001ST and the IRT-
1002ST offer the Call Detail Record (CDR) function to help you analyze
and manage your telephone bill.

PLANET ISDN Router

RADIUS (Remote Authentication Dial In User Service)
The RADIUS feature allows you to use a central external Unix-based
server to support thousands of users (IRT-1002ST only).
PPP Security
The IRT-1001 and IRT-1002 support PAP (Password Authentication
Protocol) and CHAP (Challenge Handshake Authentication Protocol).
MS (Microsoft) CHAP
Your IRT-1001 or IRT-1002 and a Microsoft Windows 95 or Windows NT
server 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 IRT-1001 or IRT-1002 supports both RIP-1 and RIP-2 (Routing
Information Protocol versions 1 and 2) exchanges with other routers.
RIP version controls in setup menus 3.2 (TCP/IP and DHCP Ethernet
Setup) and 11.3 (Remote Node Network Layer Options) let you control
RIP use, and offer the following version options: RIP-1 (accept and send
RIP-1 messages only), RIP-2B (accept RIP-1 and RIP-2 messages, both
broadcast and multicast, and send RIP-2 messages in broadcast
format), and RIP-2M (accept RIP-1 and RIP-2 messages, both
broadcast and multicast, and send RIP-2 messages in multicast format).
(The suggested choice in both menus is RIP-2B, except in environments
where there are routers that do not understand RIP-2 packets at all.
“Broadcast,”above, means a destination MAC or IP host address
consisting of all binary ones; “multicast”means a MAC address of
01:00:5E:00:00:09 hex or an IP destination address of 224.0.0.9.)

IRT-1000 series User's Guide 5
DHCP Support (Dynamic Host Configuration Protocol)
DHCP (Dynamic Host Configuration Protocol) allows you to dynamically
and automatically assign IP address settings to hosts on your network.
Call Control
Your IRT-1001 or IRT-1002 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 IRT-1001 and IRT-1002 incorporate Stac data compression and
CCP (Compression Control Protocol).
Networking Compatibility
The IRT-1001 and IRT-1002 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.
Applications For Your IRT-1001 or IRT-1002
Some applications for the IRT-1001 and IRT-1002 include:
Internet Access
Your IRT-1001 or IRT-1002 supports the 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.

Internet Single User Account (SUA)
For small office environments, the IRT-1001 and IRT-1002 offer a
Single User Internet Account (also known as a Network Address
Translator, or NAT) from an ISP (Internet Service 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 IRT-1001 and IRT-1002 can dial to or answer calls from another
remote access router connected to a different network. The IRT-1002
supports TCP/IP and Novell IPX, and has the capability to bridge any
Ethernet protocol.
Telecommuting Server
The IRT-1001 and IRT-1002 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., Windows 95, to dial in
using an ISDN terminal adapter (TA) to access the network resources
without physically being in the office.

order it from your telephone company as soon as possible to avoid the
long waiting period common when ordering a new line. Use the
information in this section to place the order (see the ISDN Switch
Types chapter for information on provisioning your ISDN line). If you
have already installed your ISDN line, you can check the following
section to make sure that you can use all the features of your IRT-1001
or IRT-1002.
1. Contact your local telephone company’s ISDN Ordering Center.
2. Find out what type of ISDN service is available. Refer to the ISDN
Switch Types chapter to find out the provisioning information for
the appropriate switch type and ISDN service. For the U.S., the
IRT-1001U and IRT-1002U (U Interface) have been approved by
Bellcore and have IOC (ISDN Ordering Code) “S”Capability, EZ-
ISDN 1.
3. Provide your telephone company with the proper provisioning
information.
4. When the telephone company installs your ISDN line, be sure to
obtain the following information:
◊ISDN switch type.
◊ISDN telephone number(s).
◊ISDN Service Profile Identifier (SPID) number(s) (only for
North America).
