Enables technicians to install and troubleshoot copper-based single pair and bonded pair VDSL2 and ADSL2+ circuits the right-way -- dual ended with UltraFED IIB.

Dual-ended copper testing with an UltraFED IIB can isolate customer-affecting fault conditions that otherwise go undetected during turn-up and installation or routine copper troubleshooting.  The UltraFED IIB connects to the far end of copper pairs under test while a single technician controls it remotely using the VIAVI HST-3000 or ONX-580.

Benefits

• Reduces back-and-forth drive time to change line conditions Provides line terminations and remote test capabilities
• Built for the future -- isolates crosstalk for VDSL2/ADSL2+ bonded pairs
• Thru-mode operation takes customers out of service only when necessary
• Greatly simplifies fault isolation and identification for less-skilled technicians
• OneCheck™ diagnostics identify faults up to three times faster

Applications

• Second-pair operation to accurately assess the effects of near-end crosstalk (NEXT) and far-end crosstalk (FEXT)
• Remotely, from the VIAVI HST-3000, provide strap (short), open, drop battery, transmit tones and trace tones
• View pair endings with TDR Helper, enabled on the HST-3000, which provides alternating short and open to the pair
• OneCheck Copper Test Suite provides simple diagnostic tests that isolate typical faults a technician encounters every day
  • OneCheck Copper for DSL - Determines overall pair(s) health over the DSL technology provided  with thresholds and filters set by technology
  • OneCheck Series Fault - Check for series fault presence, typically  from splice failures
  • OneCheck Bridged Tap - Determines bridged tap (lateral) existence on the pair with distance to  and length of tap
  • OneCheck TrueLength - Provides actual pair length by correlating capacitive, resistive and TDR  loop measurements
  • OneCheck RFL Pretest - Indicates whether a resistive fault was  found and identifies to run next to precision locate it
  • OneCheck Kick Test - Quick copper-check to assess the pair's health prior to final test
  • OneCheck Shield Test - Determines resistance from the HST-3000 to the UltraFED IIB
