INTRODUCING THE SUPERSTACK II

1 REMOTE ACCESS SYSTEM 1500

This chapter contains information about the SuperStack II® Remote Access System 1500 (RAS 1500) and how it can be used in your network.

This chapter contains the following information:

■About the RAS 1500

■Overview

■Applications

■Security options

■Configuration options

■Front Panel View and Description

1-2 CHAPTER 1: INTRODUCING THE SUPERSTACK II REMOTE ACCESS SYSTEM 1500

About the RAS 1500 The RAS 1500 is a stackable unit that provides terminal server and remote

	access services, via analog and ISDN BRI connections in a multi-protocol
	networking environment.
	Consisting of a base router module (RM), port expansion module (PEM),
	and user-installable Input/Output (I/O) modules, RAS 1500 integrates
	multiprotocol remote access server and WAN router technology with
	high-performance 56 kbps (V.90) and/or ISDN modems.
Overview	The RAS 1500 is a powerful data communications platform that can
	support a broad variety of remote access applications.
	The basic configuration of a RAS 1500 stack consists of one RM and two
	PEMs and supports up to 24 channels (up to a total of 12 BRI lines, 24
	analog lines, or any combination up to 24 channels).
	In a full RAS 1500 stack, each PEM is connected to the RM using 3Com’s
	StackNet, a high speed (up to 200 Mbps), low cost technology.

Overview 1-3

Applications

The RAS 1500 is a multi-protocol, dial-up router and terminal server commonly described as a remote access server. The RAS 1500 performs five basic applications:

■IP Terminal Service

■Network Dial-in Access

■Dial-out Access (NCSI or telnet)

■LAN-to-LAN Routing

■Bridging

For more information about configuring these basic applications, see the SuperStack II Remote Access System 1500 Resource CD-ROM.

Figure 1-2 Application of the RAS 1500 within the IP Network

IP Terminal Service

RAS 1500 provides network access for dumb terminals or computers that emulate dumb terminals. The ASCII data stream to and from these remote terminals is converted into a networking protocol (telnet, Rlogin, or ClearTCP) and a session is established with a host to provide an IP terminal service connection on the RAS 1500’s local network.

1-4 CHAPTER 1: INTRODUCING THE SUPERSTACK II REMOTE ACCESS SYSTEM 1500

The RAS 1500 offers extensive access security, dialback, and easy configuration for terminal service connections.

Network Dial-in Access

RAS 1500 provides dial-in network access for remote users. Remote IP, IPX and Appletalk network users can dial in and connect to the local network as if they were local nodes.

Packets transmitted over the dial-in connection are encapsulated using the following protocols:

■PPP (Point-to-Point Protocol)

■SLIP (Serial Line IP Protocol)

■FCP (3Com’s Fast Connect Protocol)

Dial-out Access

You can access RAS 1500 ports with network computers and workstations to provide users with NCSI and Telnet dial-out services. This allows network users to connect to Bulletin Board Systems (BBSs) or information services such as CompuServe, or access the Internet over a dial-up connection.

IP or IPX LAN users require a NCSI-compatible communications application to access RAS 1500 modems.

LAN-to-LAN Routing and Bridging

RAS 1500 performs dial-up routing over a PPP connection between facilities. Routing occurs when one device dials up another device and logs in as a user.

There are several types of LAN-to-LAN connections:

■Manual

■On demand

■Timed

■Continuous

RAS 1500 supports many routing and protocol configurations. It is capable of establishing additional connections to increase bandwidth automatically when network traffic increases.

Security Options

Configuration

Options

Universal Connect

RAS 1500 supports the following security options:

■IP packet filtering in both the inbound and the outbound directions of ports, users, and dial-out locations.

■RADIUS

■NOS-based authentication (Windows NT 4.0, Novell NetWare)

■Dial-back, fixed and roaming

■PAP and CHAP

■Local password authentication

The RAS 1500 supports the following configuration options:

■TRAM

■Command Line Interface (CLI)

TRAM

TRAM allows you to configure your RAS 1500 using a GUI interface, if you are using Windows 95 or Windows NT 4.0.

Command Line Interface

The RAS 1500’s CLI includes an assortment of utilities for troubleshooting connections including:

■The ability to manually dial a location to test connectivity

■The ability to use telnet, Rlogin or ClearTCP to establish a session with another host.

■UNIX-like troubleshooting commands including ping to debug IP connections.

Universal Connect allows ISDN I/O module users to access information at analog speeds up to 56 Kbps and at digital speeds up to 128 Kbps from the same equipment and port.

ISDN Configuration The RAS 1500 supports Basic Rate Interface (BRI) ISDN with either the U-Interface (for North America) or the S/T-Interface (for other countries). Contact your ISDN provider for information about ISDN in your area or call 1-800-877-ISDN (USA only).
