Performance marking Connection hardware should be marked to designate transmission  performance at the discretion of the manufacturer or the approval agency. The marking, if any. shall be visible during installation. It  is suggested that such markings consist of. "Cat 3" or  ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ  "(3)"  for category 3 components "Cat 5e" or "(5e)"  for   category 5e components "Cat 6" or "(6)"  for  category 6 components "Cat 6A" or "6A" for  category 6A components NOTE - Performance markings are in addition to, and do not replace, other markings required by listing agencies or those needed to satisfy electrical code or lacal building code requirements.

Shield mating interface (screened only) The shields of shielded 8-position modular connectors (plugs and jacks) shall be designed to ensure continuity when mated. The shield mating interface shall conform to the requirements in the IEC 60603-7 series of Standards. Modular jack shields shall not encroach upon the connector opening dimensions defined by IEC 60603-7 with the exception of shield mating contacts internal to the jack. Plug shields shall not extend beyond the plug housing dimensions defined by IEC 60603-7 in areas mating to the jack.

Insulated conductor color codes The insulated conductor color coding for cord cable and cross-connect jumpers shall comply with Table 3. Table 3 - Insulated conductor color codes for cord cable and cross-connect jumpers Pair Color code (Abbreviation) Color code (Abbreviation designation Option 1 Option 2 Pair 1 White-Blue (W-BL) Green (G) Blue(BL) Red ® Pair 2 White-Orange (W-O) Black (BK) Orange (O) Yellow (Y) Pair 3 White-Green (W-G) Blue(BL) Green (G) Orange (O) Pair 4 White-Brown (W-BR) Brown(BR) Brown(BR) Slate (S) 1) See clause 5.7.5 for corresponding connecting hardware pair assignments.

Cabling Standards Update     TIA/EIA TR 42. TIA/EIA TR 42 have the following documents out for ballot:             - TIA/EIA 568.C-0 Generic premises cabling (under development)             - TIA/EIA 568.C-1 4th revision of TIA/EIA 568             - TIA/EIA 568.C-2 Second revision of Category 6 including Category 6A             - TIA/EIA 568.C3red revision of Fiber Optic standards             - TIA/EIA 606A addendum 1 Administration in Data Centres             - TIA/EIA 1005 Industrial Cabling             - TIA/EIA 1005-1 Pathways and Spaces in industrial premises

Cabling Standards Update   ISO/IEC JTC1 SC25 ISo/IEC 11801 standard, started in June 2004 with the development of new Classes E and F in support of 10G BASE-T. Class E are based on the existing Class E, but extrapolated from 250 to 500 MHz for all parameters. Class FA are based on the existing Class F, but extrapolated from 600 to 1000 MHz for all parameters.

Horizontal Cabling The horizontal cabling system encompasses everything between the telecommunications room cross connects in the work area. It's specified in TIA/EIA - 568 - B.1

Horizontal run : 90meters (295.3ft) from the telecommunications outlet to the horizontal cross-connect Work area patch cord : 5 meters (16.4ft.) Total of work-area and cross-connect patch cords, Equipment cable,jumpers,ect : 10 meter (32.8 ft.)

Backbone Topology To Provide connectivity between telecommunication rooms, equipment rooms, And en5rance facility. Two-level hierarchical star. Non-star configurations                 - Ring, Bus, Tree can be accommodated though use inter connections, electronics and adapter.                 - Fault Tolerance                 - Redundancy

Work Area The work area consists of all the components between the telecommunications outlet and user's desktop workstation equipment This covers: - Telecommunications outlets, including wall-plates, faceplates, surface-mount boxes,etc -  Adapters, including connectors,and modular jacks. - Workstation equipment, such as PCs, telephones, printers, etc. - Patch cord from the telecommunications outlet to the workstation equipment should be no more than 5 meters.

Work Area The space in a building where the occupants interact their telecommunication devices. Station equipment can be different devices including computers, telephone , printers, fax etc. Minimum of two telecommunications outlet per work area. The Estimated space allocated per work area = 10 m 2  (10,000 ft 2       Mximum length of work Area Cable = 5m to 22m Depend on length of Horizontal Cable.

Work Area Telecommunications outlet should installed within 1 meter (3 ft) of a power outlet at the same height as power outlet.
