TIA568 Wiring Standards
How to decide which wiring pattern to use:
1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.
If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

Wire Finder / Mini Locator
For those technicians who occasionally need to locate buried or in-wall wiring but don't require all the "bells and whistles" of high priced locators, the 508S is for you. Its compact design doesn't take up valuable truck space while easy to understand operations keep you from constantly referring to instructions. The Model 508S provides reliable results on buried cables to depths of 3 feet and lengths up to 1000 feet. The unit can even be used to determine the approximate depth of the wire before you dig. Fully adjustable transmitter output and receiver gain improve system performance and locating accuracy. Both the transmitter output and receiver are housed in a durable, molded carrying case with a quick reference operation guide on the inside of the lid.
