DATU EXP Auto-Test
The DATU EXP Auto-Test is a fully automated sequence of parametric and
VF transmission tests, some of which are performed at the field end by the
dialing CopperPro tester, and others performed at the C.O. end by the Fluke
Networks DATU EXP test head. All test results are shared with and displayed
by the CopperPro tester, as well as stored by the DATU EXP. This stored data
may then be accessed by Telco OSS databases for reporting and
administration.
In the DATU EXP Auto-Test, the CopperPro tester provides the same test
functionality as the Fluke Networks Insight EXP™ field test set, when used in
conjunction with a C.0.-located DATU EXP test head. The three basic test
sequences provided are:
1.
Loop Test: Initial line test, comprised of three groups of tests -
a. CopperPro tester pre-tests before dialing the DATU EXP:
i. ACV, DCV, & Loop Current.
b. CopperPro Channel Tests after dialing the DATU EXP:
i. VF Metallic Noise, Power Influence, Loss &
Longitudinal Balance.
c. DATU EXP Trunk Tests after removing line battery feed:
i. ACV, DCV, Capacitance, Loop Resistance, Ground
Resistance, Leakage Resistance, & Load Coil
Measurement.
2.
5 - Step Test: Comprised of two groups of tests -
a. CopperPro Pre-Tests before dialing the DATU EXP:
i. ACV, DCV, & Loop Current.
b. CopperPro Channel Tests after dialing the DATU EXP:
i. VF Metallic Noise, Power Influence, Loss &
Longitudinal Balance.
3.
Final Test: Same as Loop Test, but after repairs completed (Closeout
test)
