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 Sidekick 7B is the test set used in every major telephone company in the United States to troubleshoot twisted pair applications. This lightweight, hand-held meter quickly and accurately uncovers intermittent troubles that other test sets can't detect. Since the introduction of the patented Stress Test and Leakage Test in 1991, the Sidekick has become a benchmark in communications technology. Technicians now have the versatility to identify faults in locations ranging from outside plant cable to inside wiring, and from closures to connecting blocks, without sacrificing standard features,e.g., AC/DC, VOM, Kick Meter, they have come to rely on. The versatile Sidekick 7B is used throughout the telephony industry, including LAN/WAN, Private Networks, and BICSI applications.

STRESS TEST

The Stress Test reads the audible noise produced on a faulted pair that is stressed by a 90 dBrn longitudinal excitation. The Stress Test determines the capacitive and series resistance ba lance characteristics of twisted pair at any point along the pair. It is capable of identifying DC resistive or capacitive imbalances undetected by other subscriber loop tests. The Stress Test is also highly effective in identifying imbalances produced by series resistance opens (high joints).

LEAKAGE TEST

The Leakage Test detects intermittent resistance faults that do not appear under normal VOM tests. When a faulted pair is taken out of service, galvanic action forms an insulating oxide layer over the faults. When returned to service, such pairs develop "noisy static" in a relatively short period of time. The Leakage Test uses 135 Volts to "punch through" the oxide layer and reveal the fault.

Features

  • Determines stressed noise susceptibility of dry and working pairs.
  • 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.
  • Improves customer satisfaction.
  • Eliminates service interruptions.
  • Provides quick return on investment
