Full Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type
of cables used. See the front cover for the cable specifications for the different
E-100BTX-FX-05(10x) models.
The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex Network
(512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet collision domain.
(A
collision domain is the longest path between any two terminal devices, e.g., a
terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled
“Collision Domains” on the Transition Networks website at:

• Straight-through or crossover cable may be used.
• Shielded twisted-pair (STP) or unshielded twisted-pair (UTP) may be used
• Pins 1&2 and 3&6 are the two active pairs in an Ethernet network .
• RJ-45 Pin-out: Pin 1 = TD+, Pin 2 = TD-, Pin 3 = RD+, Pin 6 = RD-
• Use only dedicated wire pairs for the active pins:
(e.g., blue/white & white/blue, orange/white & white/orange, etc.)
• Do not use flat or silver satin wire.
