cable - Cable (outlet) - The data outlet that users connect their machines to are actually one end of a single cable run, that terminates in a room of network equipment. The "Outlet Number" actually identifies the cable by indicating the physical locations of each end using a labelling scheme appropriate for the type of cable installation. So what is often referred to as an outlet number is actually a cable designation. The "from" and "to" vernacular that is used in some documentation is really just another way of expressing "that cable that runs FROM here TO there." Cables/Outlets are not a network connection until they are attached to a device/port that will supply network connectivity to that cable. For an outlet that users would plug their computers into, the bottom line ('To') is the end of the cable in their office or residence. The Top line ('from') is the end that will be connected to the network equipment. Therefore, the two pieces are unique identifiers that work together to identify a single cable run. This means that if any part of the outlet label is obliterated, it may be possible to figure out the rest from what is readable. Pattern counts, so a typical label would look something like this:

    13@01-342-E7  
    13@01-@E032
See Registering an Outlet for more information about how to do this.

Additionally, the Cable ID is a unique number that is assigned to an outlet/cable for internal use within the registration system. It's function is primarily for use within the registration system itself, as a unique database identifier.
