Using DSLe will reduce repeats by identifying problems relating to Outside Plant that may not be captured by
other testing tools (i.e.: KIT/BLAST)
Using DSLe properly will allow us to provide excellent service on the first visit with no repeats.
When to use it?
Every TV/DSL trouble where Insight indicates a failure on the cable pair or modem
Using DSLe does not replace the requirement to run Insight, BLAST, or KIT on any job but will
limit the drive time by identifying possible areas for repair outside the customer’s home
Any time you need to diagnose a Bonded DSL trouble
BLAST tests cannot be run on a Bonded circuit, but DSLe can analyze the data on both lines
and see any errors on the modem.
Figure 140: Red flags indicating a likely issue with the distribution pair. Excess errors on the
modem will cause modem instability (11 retrains in 24 hours in the bottom example) leading
to poor service quality for the customer.
