E-TBT-FRL-xx00 IN THE NETWORK

Each media converter port in the multi-port media converter operates
independently over one isolated twisted-pair copper/fiber-optic cable
link. The media converter port receives and transmits network signals in
either full-duplex or half-duplex, depending upon the network devices
to which the media converter port is attached.

NOTE: In Telco option (not shown), the 50-pin Telco connector
concentrates up to 12 UTP connections onto one connector. This
concentration of UTP ports is then broken out for connection to fiber.

RJ-45 CONNECTOR

Twisted pair connection requires two active pairs configured as straight
through and/or crossover. The two active pairs in an Ethernet™ network are
pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as blue/white
& white/blue, orange/white & white/orange) for the active pins.

NOTE: The multi-port media converter AutoCross™ feature allows either straight­through or crossover twisted-pair copper cable to be used when connecting to
10BASE-T devices. AutoCross™ determines the characteristics of cable
connections to the media converter port and then automatically configures the
port to link up.

Either shielded twisted-pair (STP) or unshielded twisted-pair (UTP) can
be used. DO NOT USE FLAT OR SILVER SATIN WIRE.

CATEGORY 5:

TELCO SIGNALS

Media Converter Port in Full-Duplex Network

In a full-duplex network, maximum cable lengths are determined by the
cables used. See page 10 for cable specifications.

NOTE: The 5-Segment Rule described below does NOT apply in a full­duplex network.

Media Converter Port in Half-Duplex Network

The 5-Segment Rule applies separately to each collision domain.

USING THE 5-SEGMENT (5-4-3) RULE:

NOTE: A segment is the cable connection between network interfaces.
In any 10-Mbit/sec Ethernet collision domain, the 5-Segment Rule allows no

more than five segments. The 5-4-3 Rule version of the 5-Segment Rule
allows no more than five segments and also allows no more than four
repeaters (hubs) and three populated segments (10Base-2 coaxial-cable
installations).

To determine the size of the collision domain by assigning segment numbers
to cable connections, determine the two network devices in a transmission
path that are separated by the greatest number of segments. Define a segment
path between the network devices by labeling the cable connection to the
first device “segment 1” and numbering each segment in the path to the last
network device, up to “segment n” (n = total number of segments ≤ 5).
Verify that no segment path in the entire collision domain contains more than
n ≤ 5 segments.

Set LinkAlert™Switches

USING LINKALERT™

NOTE: The E-TBT-FRL-xx00 series multi-port media converter LinkAlert

™

feature allows each media converter port to pass 10BASE-T side link faults
over the port link to the 10BASE-FL side and to pass 10BASE-FL side link
faults over the port link to the 10BASE-T side.

If the port does not detect a good link on the 10BASE-T side, the port disables
all transmission (including active-idle) on the 10BASE-FL side.

SWITCH SETTINGS

Use the 2-position switches at the front of the E-TBT-FRL-xx00 to
enable/disable LinkALERT

™

for three contiguous media converter ports.

SWITCH 1 enables or disables LinkAlert

™

for ports 1 - 3,

SWITCH 2 for ports 4 - 6. SWITCH 3 enables or disables

LinkAlert

™

for ports 7 -9 in a 12-port unit and SWITCH 4 for

ports 10 -12.
