About the PathBuilder S21x Switch

Overview

Introduction

The 3Com PathBuilder S21x switch is a compact network access device for

connecting LAN and serial devices to public and private networks services such as

frame relay and X.25. The PathBuilder S21x switch is a desktop-size standalone

device supporting up to two optional daughtercards, as shown in Figure 1-1. Using

the optional daughtercards, the PathBuilder S21x switch offers a flexible and cost

effective solution for transporting data, voice, and video across a network.

1-2 About the PathBuilder S21x Switch

Features

Standard Features

The base PathBuilder S21x switch provides the following:

• External power supply

• Control Terminal Port (CTP) for local and remote configuration and

management

• Ethernet interface (10BaseT)

• One Serial DIM Port

• Two daughtercard slots

CTP Port

Port 4 can be used as a Control Terminal Port (CTP) for configuration, reporting, and

troubleshooting the PathBuilder S21x switch. To set Port 4 as CTP, put the front

panel dip switch 4 into the UP position. To access the CTP you must also configure

your terminal or terminal emulation software, to VT100, 9600 bps, 8 bit, no parity, 1

stop bit.

Dual Daughtercard

Slots

The PathBuilder S21x switch comes with two slots to support optional

daughtercards. This permits easy future expansion of the product.

Operating Software

Operating software is compressed in FLASH memory and loaded into DRAM for

operation. The PathBuilder S21x switch supports these Applications Ware packages:

• IP Applications Ware Package

• IP & IPX Applications Ware Package

• SNA Applications Ware Package

• Serial Protocol Applications Ware Package

• Multiservice Applications Ware Package

• Multimedia Applications Ware Package

See the

Software Release Notes

accompanying your PathBuilder S200 series switch

unit for more information on the software available for the PathBuilder S21x switch.

Features

Daughtercard Functionality

Introduction

The PathBuilder S21x switch is available with the optional components listed below

factory-installed or as separate add-in daughtercards.

• Voice Relay Daughtercard

• Dual FXS Voice Relay Daughtercard

• RemoteVu Daughtercard

• DSU Daughtercard

• DIM Daughtercard

• DRAM SIMMs

Refer to the

PathBuilder S200 Series Switch Daughtercard Installation Manual

(T0020) for information on the installation of optional daughtercards.

Voice Relay

Daughtercard

The PathBuilder S21x switch supports the Voice Relay Daughtercard. This

daughtercard supports one voice channel, using either an analog FXS or FXO

interface. Both interfaces use RJ11 connectors.

Dual FXS Voice

Relay

Daughtercard

The Dual FXS Voice Relay Daughtercard provides two FXS interface ports and

support one voice channel each. The FXS port uses RJ45 connectors.

RemoteVu

Daughtercard

The PathBuilder S21x switch supports video over Frame Relay using the RemoteVu

daughtercard. The RemoteVu Daughtercard provides two BNC connector, video

ports accepting NTSC, PAL or SECAM video signal standards and an RJ-45, RS232/

485 camera control port used for Pan/Tilt/Zoom (PTZ) camera control.

DSU Daughtercard

The DSU daughtercard functionality suits an extended range of 56 kbps

point-to- point DDS1 interfaces that conforms to AT&T 62310 or

ANSI T1E1.4/91-006.

The DSU is FCC Part 68 registered.

Diagnostic loopbacks from the telephone company are supported; local diagnostics

are activated from the CTP.

About the PathBuilder S21x Switch 1-5

Features

Software Functionality

Introduction

Depending on the operating software AppsWare package and optional daughtercard

installed the PathBuilder S21x switch can support the following functionality and

services.

Frame Relay & X.25

Service

The PathBuilder S21x switch provides serial devices with economical Ethernet LAN

access into public or private Frame Relay WAN. Where frame relay services are not

yet available, the PathBuilder S21x switch can provide network access over X.25

services. When frame relay services becomes available, the PathBuilder S21x switch

can be easily configured and integrated to support frame relay. This fast migration

reduced network downtime and protects hardware investments.

RFC 877 and 1356

The PathBuilder S21x switch supports encapsulation of IP datagrams and other

network layer protocols over X.25 as specified in RFC 877 and RFC 1356. This

allows for interoperability with Front End Processors (FEPs) that support X.25 and

IP traffic as well as router vendors supporting RFC 877/1356.

RFC 1490

The PathBuilder S21x switch supports encapsulation of multiple protocols over

frame relay as specified by RFC 1490.

Multiprotocol

Support

Support includes SDLC, Bisync, X.25, Async, IP/IPX, PPP, MLPPP, and Routing

and Bridging, as well as many other serial protocols. Refer to the Software Release

Notice which accompanied your unit for a complete listing of protocols supported by

the PathBuilder S21x switch.

1-6 About the PathBuilder S21x Switch

Target Application Environments

Introduction

This section describes example applications for the PathBuilder S21x switch.

LAN and Legacy

Protocol over

Frame Relay

The PathBuilder S21x switch supports multiprotocol encapsulation of IP traffic and

legacy serial protocols over frame relay as specified by RFC 1490. As shown in

Figure 1-2, a SNA cluster controller connects to a serial port on the PathBuilder S21x

switch and the Ethernet LAN connects to the 10BaseT Ethernet port. The PathBuilder

S200 series switch is fully interoperable with third party routers via RFC 1490.

Video and Legacy

Protocols over

Frame Relay -

Banking

Application

As shown in Figure 1-3, the PathBuilder S21x switch can support encapsulation of

video and legacy protocol over frame relay. This use of PathBuilder S21x switch

suits banking applications such as Automated Bank Machines (ABMs). With Dial on

Demand software feature enabled, the PathBuilder S21x switch initiates a connection

only when there is data transfer, i.e. only for the duration of a bank transaction. The

RemoteVu Daughtercard can capture video and send video streams to the central

bank’s security system.

DSU DIM and Voice

Relay Daughtercards

The PathBuilder S21x switch supports voice, video and

data traffic between the branch and central office over pri-

vate or public frame relay network. The Voice Relay

Daughtercard supports telephones, PBX, and faxes.

Connect a telephone or PABX to one FXS port on the

Voice Relay Daughtercard and all branch telephones have

access to the central office PBX. This eliminates long

distance telephone charges between the branch and

central office.

Security

Monitoring at

Branch Office

RemoteVu and DSU

Daughtercards

The PathBuilder S21x switch equipped with a RemoteVu

Daughtercard provides security surveillance and remote

monitoring of the branch office location from the central

office. The RemoteVu Daughtercard packetizes video

stream in IP and sends the data over the frame relay.

Security personnel at the central office can control the

branch office video camera from a PC running the Host

Video Workstation application.
