The L6004, L6004A, and L6004B can be used to connect two PCs or workstations through a single 4 pair cable run. All three are Cat 5e rated.

The wiring is the same for all three, so they can be used interchangeably. For example, the L6004B
could be used in the wiring closet (connecting direct to the switch/router ports) while the L6004
could be used for the workstations.
One of these needs to be at each end of the 4 pair cable run. A single unit can’t allow two workstations to connect to a single port on the switch or router.
