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.  For 
unshielded twisted-pair (UTP) cabling, Category (CAT) 3, 4 or 5 can be used.   

With the advent of 100Mbit network products, it is best to use higher quality 
CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch panels 
and connectors while following the EIA/TIA wiring standards.  100 Ohm 
UTP/STP CAT 3, 4 & 5 type cables use 4-pair UTP wiring. Standard 10BASE-
T uses 2-pair UTP wiring. 

Refer to the illustrations below for standard 2-pair 10BASE-T wiring (see Fig 
B-4), and 4-pair 100Mbit wiring using either T568A (Fig. B-5) or T568B (Fig. 
B-6) wiring standards. Both T568A and T568B wiring is compatible with 
10BASE-T and require no special configurations, but mixing the T568A and 
T568B wiring schemes will not work.
