Basic Cablling
What connectors are used with UTP?
UTP uses a connection called the RJ-45 connector. It looks similar to a common telephone connector (RJ-11) except it is slightly larger. The RJ-45 has 8 pins while the RJ-11 has only 4.
UTP cable typically runs from a computer�s NIC and plugs directly into a wall plate much like a regular telephone. It is not uncommon to find wall plates in newer buildings labeled as �Voice� (for telephones) or �Data� (for UTP). The cable running from the wall jack is rarely attached directly into a hub. Instead the individual cables are collected and organized with patch panels located in a �wiring closet.�
