Running a Loop Current & Ground Ohms Test
1. From the POTS Toolbox, select Loop Cur. & Gnd Ω, and press K.
• If the T-R DC Voltage measured was not Idle POTS as specified in
DCV Setups, the tester displays a message asking you whether or not
to proceed, to avoid disruption of a possible non-POTS service.
• If you select
Yes to continue, and there is insufficient T-R voltage to
yield a meaningful measurement, the tester displays a
No T-R Voltage
message.
• Otherwise, the tester displays a result screen listing the three test
results.
2. Press the desired function softkey to view continuous test results for any
of the three tests.
Dial-Up Test Group
The Dial-Up Test group consists of terminated VF transmission tests that are
conducted on idle working POTS lines. These tests operate by dialing various
C.O. equipment, with the exception of the DID / DOD tests (*), which are used
to test analog PBX trunk facilities. These PBX tests require an optionally-
purchased software feature package, described in a separate Users Guide
Addendum. The following is a list of test functions in this group:
• Milliwatt VF Loss Test
• Quiet Termination VF Noise Test
• Quiet Termination VF Long. Balance Test
• Number ANI Test
• On-Hook Caller ID Test
• Call Waiting Caller ID Test
• Monitor Line Function
• Smart-Pro Test Group
• SASS Test Group
• DATU Test Group
• DATU EXP Auto-Test
