6. Network Investment A cabling system supports and outlives most network components, yet represents only 5% of the total network investment
7. Facilitates Moving Employees Within A Building Moves, adds and changes are inevitable: 40% of employees move within their building every year. These activities can cause serious work-flow disruptions with an unstructured cabling system. A structured cabling system allows moves, adds and changes to occur quickly and cost effectively.
8. Cost Of Downtime Network downtime costs between $ 1,000 and $ 50,000 an hour. Preventing downtime with the use of a structured cabling system can save substantial amounts of money .

Two wiring schemes have been adopted. They are nearly identical except that pairs two and three are reversed. T568A is the preferred scheme because it is compatible with 1 or 2 pair USOC systems. Either configuration can be used for Integrated Services Digital Network (ISDN) and high speed data applications. Transmission Categories 3, 4, and 5 are only applicable to this type of pair grouping.

USOC wiring is available in 1, 2, 3 or 4 pair schemes. Pair 1 occupies the centre conductors, pair 2 occupies the next two contacts out, etc. One advantage to this scheme is that a 6 position plug configured with 1, 2 or 3 pairs can be inserted into an 8 position jack and maintain pair continuity. A disadvantage is the poor transmission performance associated with this type of pair sequence. NONE of these pair schemes are cabling standard compliant.

Asynchronous Transfer Mode (ATM) is an evolving wide and local area network standard for total information transport. ATM is a cell-based packet switching protocol (ISO Layer 2) that is capable of supporting multimedia traffic at very high (gigabit) speeds in the same transmission. ATM runs on fibre-optic or twisted pair media. It offers universal, service independent switching and multiplexing capabilities. 1/. Patch panel 2/. Fibre management system 3/.

The IEEE 802.3 100Base-T specification is the standard for Ethernet communications over 100 ohm unshielded twisted pair (UTP) cabling. The IEEE 802.3 10Base-T specification is the standard for Ethernet communications over unshielded twisted pair (UTP) cabling. The EIA 568B wiring sequence is the recommended solution for operation of both 100Base-T and 10Base-T LANs. 100 Base-T / 10 Base-T Modular Interface Hub Cabling 1/. Hub (customer supplied) 2/.

The IEEE 802.5 Token Ring is a token passing, base band system where messages are transmitted at a rate of either 4 or 16 Mbps. The data rate of a given ring is determined by the data rates if the workfloor Network Interface Cards (NIC’s). All NIC’s on a given Token Ring MUST operate at the same speed (4 or 16 Mbps). A Multi-floor Access Unit (MAU) or cabling concentrator is used to create a star wired ring topology. EIA 568A Token Ring Cabling 1/. Token Ring MAU 2/. UTP, STP CAT 5 patch cord 3/.
