1. INTRODUCTION
This guide is intended for the system or network administrator
responsible for installing and monitoring a TRANSITION Networks
Ethernet™ 2-Port Multi Media Repeater. A working knowledge of
local area network (LAN) operations, including familiarity with
communications protocols used on interconnected LANs, is
assumed.
The Multi Media Repeater
The TRANSITION Networks Ethernet™ 2-Port Multi Media Repeater
(MMR-2), is a small, multi-purpose Ethernet repeater that is siteconfigurable, using Slide In Cards (SICs), for various signal
transmission media.
• SICs, if installed, provide fiber optic, male and female AUI,
BNC, and/or RJ-45 connectors.
• Allows for future network expansion by swapping SICs.

warranty for other reasons, then:
• Call the distributor or contact TN.
• Request a Material Repair Authorization number (MRA).
• Ship the item(s), prepaid, in the original packaging to Transition Networks at the
above address.
• Include the MRA number on the outside of the carton add/or on the Packing List.
