Loop Devices Test Results

To run this test, follow the instructions under "Starting and Stopping a Test in
the POTS Toolbox", earlier in this chapter.
Upon completion of the test, the CopperPro displays a result screen that lists
each loop device and indicates whether or not it was detected on the test pair.
A indicates that the device was detected, and an indicates that the device
Y N
was not detected.

Leakage Stress Test

The Leakage Stress test is a continuous resistance test that uses a higher test
voltage than normal, in order to "punch through" a potential metallic wire fault
that has oxidized over time. During normal resistance testing, this type of fault
will not typically show up on a spare pair. However, it will gradually appear
under sustained application of C.O. battery voltage after being cut into service
as a supposedly "good" pair.

Setting Up a Leakage Stress Test

To set up a Leakage Stress test, follow the instructions under "Displaying a
Setup Menu" in Chapter 3. The test has one setup parameter, which is listed in
Table 4-6.
