Terminated VF Tests
Terminated VF Tests are a group of double-ended, voice frequency Auto-
Tests that require a far-end terminating device such as the TN2x00 "
Terminator" or "SmartStrap"; 3M "FED" or "FEDII"; or CMC "My Helper".
The CopperPro automatically controls the Terminator, FED and Helper over
the same pair, thus not requiring a separate control pair. The SmartStrap
requires a separate control pair.
During the Auto-Tests, the CopperPro first runs a sequence of single-ended
parametric tests. It then conducts a series of terminated VF transmission tests
to effectively qualify the pair for voice frequency POTS service. The following
individual tests are conducted:
•
AC & DC Voltage
•
Shorts & Grounds
•
Opens
•
Load Coils
•
VF Noise
•
VF Longitudinal Balance
•
Tip, Ring, Loop and Ground Resistance
•
Resistive Unbalance
•
10-Tone Slope (SmartStrap, FED, FEDII, and Helper)
•
SmartTone Loss & Slope (TN2100 Terminator)
Setting Up a Terminated VF Test
To set up a test, complete the following:
1.
Set the Pass thresholds for each individual test (see previous list).
2.
Set up the Auto-Test. Do the following:
