INTRODUCTION

1.1 INTRODUCTION. The Cabletron Systems MR-2000C Multiport Repeater is an easy to install meth-
od of connecting two thin-net cable segments to a thick or thin-net cable segment, or to a fiber optic link
segment. This repeater fully conforms to IEEE 802.3 specifications and provides the flexibility to connect
networks using Ethernet Version 1, Version 2, and/or IEEE 802.3 equipment.
These segments are connected by first attaching a BNC tee connector to the BNC port located on the rear
of the repeater. The BNC tee connector allows two thin-net segments, that can be 185 meters in combined
length, to be connected to the repeater. The thin or thick-net cable segment, or the fiber optic link segment,
is then connected to the repeater by attaching an external transceiver to that segment. An attachment unit
interface (AUI) cable is then used to connect the external transceiver to an AUI port, also located on the
rear of the repeater. All three segments are linked when they are attached to the repeater. The MR-2000C
will transmit re-timed data packets, regenerate preambles, extend collision fragments, automatically par-
tition problem segments, and automatically reconnect non-problem segments.
The MR-2000C also incorporates Cabletron Systems' LANVIEW™ diagnostic system. Should a problem
arise, power failures, collisions, cable faults and many other problems can be diagnosed rapidly by using
a series of LEDs.
