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.

Applications
The new Sidekick T&N combines the functions of the Sidekick 7B plus the features of Transmission and Noise testing. The result is an even more versatile test set that identifies frequently missed faults as well as tests and qualifies the transmission quality of POTS lines. The additional features include:
- Loop Current testing
- Circuit Loss testing
- Metallic Noise testing
- Power Influence testing
- Load Coil detection
The familiarity of the Sidekick's analog meter and rugged, lightweight design, combined with five new test functions, provide quality loop testing for POTS lines.
Features
- Determines stressed noise susceptibility of dry and working pairs.
- Five Transmission and Noise Tests
- Measures resistance, AC/DC volts, and capacitive kick.
- Minimal drying effect in all ranges.
- Single setup for testing Tip-Ring, Tip-Ground, and Ring-Ground.
- Provides tone for twisted pair or crossed conductor identification.
- Low Battery indicator light.
- Field replaceable leads.
- Soft case with adjustable strand hook.
Benefits
- Works on any twisted pair application.
- Increases technician productivity.
- Reduces repeat service calls.
- Increased testing capabilities.
- Reduces training time.
- Eliminates service interruptions.
- Provides quick return on investment.
- Reduces the number of test sets required
