INTRODUCTION

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.

1.4TRXI 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.
