Table 7-1: Twisted Pair Cable Types and Associated Networks
Cable Type Network Examples
TIA Cat 3, 5e, 6 UTP or STP and 7 STP Ethernet, Fast Ethernet, ATM, and Gigabit
Ethernet
ISO Class C, D, E and F UTP or STP Ethernet, Fast Ethernet, ATM
TP-PMD / TP-DDI FDDI or ATM on Copper
10Base-T Ethernet
Single Pair Telephone, Apple Local Talk, ISDN
Shielded Two-Pair (1,2,7,8) ATM, Fiber Channel on Copper
Shielded Twisted Pair (STP)
Testing the continuity of the shield is important and requires shielded test leads at
both the Display Handset and Remote Handset. When testing STP, be sure to
select Shielded Cable Type (STP) in the Cable Type menu.
Twists are maintained to within ½”
as required per TIA Category 5e
insulation guidelines

USOC Wiring
If a USOC (Universal Service Ordering Code) or other wiring scheme is used, a
special adapter may be required for connection. Refer to Appendix D, Model
Accessories for a full list of available cable adapters.
Note: If your testing requirements include connection to something other than an RJ-45
or Tera style jack, refer to Testing with Block Adapters later in this chapter.
