The HST’s copper testing features allow quick turn-up and troubleshooting of
the services provided over copper. This includes testing with DVOM, opens, power
(Mains) influence (PI), noise, balance, time domain reflectometer (TDR),
resistive fault locate (RFL), load coil detect, loss, wideband transmission
impairment measurement set (WBTIMS), caller ID, and POTS dialer.
The HST provides process customization through on-board auto tests and allows
workflow improvements via connectivity to craft access terminals and back-office
systems.
The copper testing features include the following:
- Measuring AC and DC voltage, current, and resistance
- Measuring to opens (length of cable)
- Measuring balance, noise, and power (Mains) influence (PI)
- Locating cable faults with the TDR or RFL
- Detecting load coils
- Measuring loop loss (voiceband) including receiving and sending tones;
transmission impairment testing (noise, SNR, return loss)
- Voice service and caller ID (CLID) testing
- WBTIMS and WB2 TIMS testing including sending/ receiving tones; measuring
wideband, impulse, and spectral noise; and transmission impairment testing
(noise, SNR, return loss, crosstalk)
- Automatic testing using scripts, including POTS close out, good pair
check, and wideband auto tests.
