Full-Duplex Ethernet Network
Requirements
This chapter provides test parameters and specification requirements for Full-Duplex Ethernet network
cabling.

Full-Duplex 10BASE-T

All Cabletron Systems Full-Duplex 10BASE-T products require that installed
facility cabling and cable hardware meet the following minimum specifications. If
a network cabling installation is not within the limitations presented here, the
operation of the 10BASE-T products may be affected.
Note that Full-Duplex Ethernet links are dependent upon dedicated links from
one Ethernet switch to another Ethernet switch or from one Ethernet switch to a
single workstation. Both the end devices must be capable of operating in
full-duplex mode.

Cable Type

Network operations using 10BASE-T are more demanding than normal
telephony, and thus require specific, high-quality cabling in order to function
properly. The 10BASE-T specification for Ethernet networks requires UTP cabling
of Category 3, 4, or 5. Categories of UTP cabling below Category 3 may not meet
the quality requirements of the networking specification, and may therefore be
unable to meet the tested characteristics listed below.
The Category of cabling used in a network installation is dependent upon all the
components that make up the cabling run. If an installation utilizes Category 5
cabling, and the wallplates and patch panels to which that cabling is connected
are Category 3 compliant, the cable will not meet the EIA/TIA end-to-end
specifications for a Category 5 installation.
