copper-based Bounded Media consisting of at least one pair of twisted, insulated copper wires

TP is also categorized as plenum-rated or riser-rated. A plenum is a horizontal space in a structure used for air circulation as part of heating, ventilation, and air-conditioning (HVAC).

It can be shielded which protects against Interference

Straight-Through Cable

a TP segment using either ANSI/TIA-568A or ANSI/TIA-568B at both ends. A straight-through cable is used to connect dissimilar devices. Ex: A PC connected to a switch uses a straight-through cable.

Crossover Cable

a TP segment using ANSI/TIA-568A at one end and ANSI/TIA-568B at the other end. A crossover cable is used to connect similar devices. Ex: a switch connected to another switch uses a crossover cable to interconnect the switches.

Rollover Cable

a TP segment with opposite pin assignments on each end of the cable. A rollover cable is also known as a console cable. A rollover cable is used to access a device’s interface or console. A console port allows the connecting device to make configuration changes.
