inbound cable may be different than the outbound cable due to the change in position of the pair in the two
cables. Compare the maximum signal before the splice and after the splice to confirm a fault location.
6.
Verify the location when the appropriate indication is detected by comparing the average signal peaks
before and after the identified location.
a.
The signal should decrease significantly for shorts, crosses, and grounds.
b.
The signal should increase when crossing the point where a pair splits. If moving from the spit
section to the un-split section, the signal will decrease.
c.
Refer to the pictures above.

DAP-125
The DAP-125 and SR-101 provide a means of non-intrusively detecting the type of service, DSL for example, on a
pair without making an electrical connection. This configuration is also used to locate identification tone being
sent on a cable pair from tone sources.
Tone sources compatible with the SR-101 include:
•
AALogic TriTone Generator
•
AALogic D-105 cable pair test set
•
AALogic ATV-25 Cable analysis tester
•
Third party generators cable of transmitting one of the SR-101 frequencies.
