1.3 TRXI ACTIVE CONCENTRATOR OVERVIEW

The TRXI stand-alone concentrator provides 12 or 24 RJ45 active

Trunk Coupling Units (TCUs) for Shielded Twisted Pair (STP) or

Unshielded Twisted Pair (UTP) network lobe connections. The

TRXI-22A, 24A, 42A, and 44A are functionally identical with the

exception of the TCU lobe ports. Cabletron offers the following TRXI

conﬁgurations:

•

TRXI-22A

, twelve active RJ45 TCU lobe ports that support

category 3, 4, and 5 UTP cabling.

•

TRXI-24A

, twenty-four active RJ45 TCU lobe ports that

support category 3, 4, and 5 UTP cabling.

•

TRXI-42A

, twelve active RJ45 TCU lobe ports that support

IBM Type 1, 2, 6, and 9 STP cabling.

•

TRXI-44A

, twenty-four active RJ45 TCU lobe ports that

support IBM Type 1, 2, 6, and 9 STP cabling.

INTRODUCTION

Page 1-3

You can upgrade the TRXI-22A and TRXI-42A to twenty-four ports

using a twelve port upgrade kit available from Cabletron Systems

(Cabletron Part Number TRXI-24A-UGKIT or TRXI-44A-UGKIT).

The TRXI provides two additional ports for Ring In and Ring Out

(RI/RO) connections.These ports support Cabletron’s Token Ring Port

Interface Modules (TPIMs).TPIMs provide full repeater functionality.

They are not included with the TRXI, but can be ordered separately

from Cabletron.Table 1-1 lists each TPIM.

1.4 TRXI FEATURES

Active TCU Ports

The active TCU ports regenerate, reshape and ﬁlter the incoming

signal permitting UTP lobe cable lengths of up to

100 meters

and STP

lobe cable lengths up to

150 meters

at 16 Mbps ring speed.

Cable Signal Polarity

Differential Manchester encoding is utilized for each of the

concentrator module TCU ports.This permits passing data regardless

of receive link polarity.

Note

: If a reversed polarity condition is discovered,the segment should

be removed from the network and wired correctly (according to the

connector wiring shown in Chapter 2, Requirements / Speciﬁcations).

This will avoid the potential for future compatibility problems.

Speed Fault Protection

If a station attempts to insert into the ring at a ring speed

(4 or 16 Mbps) different from what is set on the TRXI, that port is

automatically bypassed to prevent the ring from beaconing.The Lobe

Port Status LED blinks indicating the port with the speed fault is

bypassed.

Local Management

Local Management provides the tools to manage the TRXI and all of

its attached segments.You access Local Management by connecting a

Digital Equipment Corporation VT™ 320 series terminal or a PC

using VT320 emulation software to the TRXI’s COM 1 port.

INTRODUCTION

Page 1-4

Token Ring Port Interface Modules

TPIMs are optional features that let you expand your trunk

connections using different media types.TPIMs have embedded

repeaters and retime all data. Cabletron offers a variety of TPIMs for

trunk Ring In or Ring Out connections.Table 1-2 lists each TPIM.

Ring Speed Switch

The Ring Speed Switch lets you select ring speeds of either 4 Mbps or

16 Mbps.The factory default setting is 16 Mbps.

Flash EEPROMs

The TRXI uses Flash EEPROMs that allow you to download new and

updated ﬁrmware using Cabletron System’s Remote LANVIEW/

Windows, version 2.3 or later or any device using BOOTP or TFTP

protocols.

LANVIEW LEDs

Cabletron Systems’ LANVIEW LED Status Monitoring and

Diagnostics System is a convenient troubleshooting tool that helps you

diagnose power failures, RI/RO status, cable faults, ring speed, link

problems, and network activity.

Cabletron’s Distributed LAN Monitor

Cabletron Systems’ Distributed LAN Monitor (DLM) is a software

option for the TRXI. DLM provides a method for locally polling and

monitoring devices on a local area network to minimize network

management trafﬁc on an enterprise, campus, or wide area network.
