Multi-Media Repeater
1. INTRODUCTION
This guide is intended for the system or network administrator
responsible for installing and monitoring a TRANSITION Networks
Token Ring 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 Token Ring Multi-Media Repeater
The TRANSITION Networks Token Ring 2-Port Multi-Media
Repeater (TR-MMR-2), is a small, multi-purpose active retiming
Token Ring repeater that is site-configurable, using Slide In Card
(SIC) connections, for ring extension and/or for port extension over
selectable media.
•
Reduces network jitter, particularly network jitter introduced by
passive MAUs, by regenerating and reshaping Token Ring
signals.
•
Data Connector (IBM Type 1) SICs allow connection to a
shielded 150 ohm Token Ring network.
•
Fiber optic SICs allow extension of Token Ring ring or lobe
connection up to 2000 meters (6600 feet).
•
RJ-45 connector SICs allow cost-effective installation of
shielded and unshielded Token Ring twisted pair.
