`Cabling Mix Within the Enterprise
`
`• 100% UTP - Most small and mid size
`organizations
`– New installations primarily 4-pair Cat 5 or 5e
`– Old installations Cat 3, 2-pair, 3-pair, 4-pair

`Cabling Mix Within the Enterprise
`
`• 100% UTP - Most small and mid size
`organizations
`• Mostly UTP, some STP - A few mid-size
`and many large organizations
`• Mostly STP - a few large organizations
`– e.g.. IBM has an estimated 1/2 million STP
`drops

`
`Cabling Mix Implications
`• With mixed cabling infrastructure
`– Solutions are sought that run over the entire
`spectrum of installed cabling
`• Legacy cabling is still an important to the
`end users
`– Need to support legacy cable can affect
`decision for entire enterprise
`– Premature replacement adds cost without
`increasing function

`
`
`
`Are there emerging
`requirements?
`• In parts of Europe use of two pair shielded
`100 ohm cabling to an outlet was and still is
`a popular choice - allowed by IS11801
`• Emerging Cat 7 cabling systems are being
`purchased with the expectation of
`supporting multiple applications with 2-pair
`per outlet

`
`CIO Objectives
`• Introduce applications based on need, and in
`part, on their ability to be replicated
`throughout the enterprise
`• Replace cabling plants that can not robustly
`support required applications
`• Choose minimum total cost solutions

`
`
`CIO Expectations
`• For large enterprises they can expect to
`have to support both legacy 2-pair cabling
`plants, and possibly new 2-pair installations,
`in addition to 4-pair wiring

`
`
`
`What Technical Solutions
`Address User Requirements?
`
`• Where 4-pair cabling is available, the 4-pair
`only solution meets requirements
`• If 4-pair are not available, then a 2-pair
`solution is the only one that will save the
`costs of re-cabling
`
`• Make sure any solution can be applied to
`legacy 2-pair as well as 4-pair cabling!
