Benefits of Blast Test
Testing can be completed remotely
Consistent testing approach
Automated testing using test sequenced dialogs
Part of service testing roadmap (Reactive > Proactive > Preemptive)
Results are stored for future reference/ Proactive analysis
VDSL2 compliant & backward compatible
MS Media Room Profile compliant; INP & Delay
DELT (Double Ended Loop Test – AKA Dr. DSL) Blast test results have been implemented to assist in
identifying Bridge Taps and / or Crosstalk impairments and to report the data rate reduction caused by
these impairments (via Insight).
