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.

What does "waterproof" mean?

Progressive takes the hype out of common phrases like "rain proof" and "splash safe"  with our revolutionary new case designs. In the test equipment world, water is the  worst enemy, so we have a tough standard for the word "waterproof". Our telephone  test sets are proof tested to an IEC IP67 rating. Meaning, these units will not only withstand a monsoon rain, they can actually be submersed in water for a period of time. (It isn't likely for that to occur because all models will actually float!) Our new plastics even won the Modern Plastics International Design Award for Electronics.

Why DigAlert

When working around telephone wiring, the chance that you will encounter digital service lines increases every day. An ordinary telephone test set can damage digital service lines or at the very least, knock them out of service for a while. With DigAlert protection you don't have to worry about accidentally intruding into digital services like ADSL, ISDN, T-1 and other high capacity circuits. We've even incorporated a unique over-voltage alarm and lockout feature in all five models in case you accidentally connect to a DSL power feed.
