Connectivity for groups of workstations in its area

connectivity for groups of workstations in its area, plus cross-connections to IDFs
or, in smaller organizations, an MDF. Large organizations may have several telco
rooms per floor, but the TIA/EIA standard specifies at least one per floor.
- Horizontal wiring— This is the wiring that connects workstations to the closest
telecommunications closet. TIA/EIA recognizes three possible cabling types for
horizontal wiring: STP, UTP, or fiber-optic cable. The maximum allowable distance
for horizontal wiring is 100 m.
- Work area— An area that encompasses all patch cables and horizontal wiring
necessary to connect workstations, printers, and other network devices from
their NICs to the telecommunications closet. The TIA/EIA standard calls for each
wall jack to contain at least one voice and one data outlet.
