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.

Token Ring Twisted Pair Network Considerations
Twisted pair cables between passive MAUs and Token Ring Multi-
Media Repeaters must be short (patch cables). The patch cables can be
either Type 1 (150 Ω) twisted pair or Category 5 (100 Ω) twisted pair.
At 16Mbps network speed, shielded twisted pair (STP) cables between
Token Ring Multi-Media Repeaters or between Token Ring Multi-Media
Repeaters and terminal equipment can be up to 400 meters (1310 feet);
unshielded twisted pair (UTP) cables can be up to 350 meters (1140
feet).

Installing Slide-In Cards (SICs)
CAUTION: Wear a grounding device and observe electrostatic
discharge precautions when installing Slide-In Cards. Failure to
observe this caution could result in circuit board failure.
NOTE: SIC card configured RI/LI MUST be installed in RI/LI SIC slot;
SIC card configured RO/LO MUST be installed in RO/LO SIC slot.
To install a Slide-In Card:
1. Determine if Slide-In Card has RI/LI-RO/LO switch and, if so,
determine if RI/LI-RO/LO switch is in correct position for the
installation. If necessary, reset RI/LI-RO/LO Switch.
NOTE: RI/LI-RO/LO switch settings are marked on Slide-In
Card component surface.
NOTE: Fiber SIC does NOT have RI/LI-RO/LO switch.
