Network Terms and Definitions

LanScaperPRO Network Tester User’s Guide 79

Multiple simultaneous point-point communications can

pass through a switch at the same time, as long as each

end point is on a different port on the switch.

Like a hub, a switch (in its primary mode) has no IP or

MAC address of it's own. Also like a hub, a switch uses

"hub" pin out on its connectors to allow direct connections

to NIC interfaces.

T568A/B

The EIA/TIA structured wiring standards for telecommuni-

cations wiring. A and B versions are electrically identical

and can not be distinguished with a wiring test. The color

codes and pair numbering is different, however, and care

must be taken to use one version within a network. A

cable wired to A on one end and B on the other results in

a cross-over cable.

UPLINK

A special connector or mechanical switch that changes

the pin out of one connector on a hub or switch to NIC pin

out. This allows a straight-through cable to be used to

connect one hub (or switch) to another while building a

LAN.
