12 Appendix B Cabling Guidelines
Kingston Technology Company KND2410TX User’s Guide - Rev. A01
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
Ω
UTP CAT 5 type cables use 4-pair UTP wiring.
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.

UTP Cable Rating Codes
UTP cables meet different UL-NEC requirements based on cable-jacket
quality. Below is an explanation of the rating codes for each cable type.
