UTP Cable Wiring Standards

There are two governmental agencies: the Electronic Industry Association
(EIA) and the Telecommunications Industry Association (TIA), which set the
standard for all cable wiring requirements for commercial buildings.
With the advent of 100Mb/s networking products, it is best to use higher
quality CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch
panels, patch cables, and connectors while following the EIA/TIA wiring
standards. 100
Refer to the illustrations below for 4-pair wiring using either T568A (Fig. B-1)
or T568B (Fig. B-2) wiring standards. Both T568A and T568B wiring is
compatible with 10BASE-T and 100BASE-TX and require no special
configurations, but for premise wiring, stick to one wiring standard. Mixing
T568A and T568B wiring schemes may cause or lead to potential problems.
