Case #3:
the pair has an
open
path in either the TIP or RING wire. Verify the pairs are properly
inserted in the punch-down block. You should also verify the pairs are properly connected to the
cross-connect and / or the POTS port of the DSLAM.
Case #4:
the pair is mixed with a POTS pair that has -48Vdc battery on it. This may override the
output from the BRX-PWR-M module. Make sure there is no wiring problem with the pair as it enters
into the cross-connect or the DSLAM POTS port.
Case #5:
the pair has its TIP and RING signal mixed with another pair. This is something referred to
as a SPLIT pair. Make sure the pair is properly inserted in the punch-down block. You should also
verify the pairs are properly connected to the cross-connect and / or the POTS port of the DSLAM.

Case #1:
pair has a shorted path between TIP and RING. Make sure the pair is properly inserted in
the punch-down block. You should also verify the pairs are properly connected to the cross-connect
and / or the POTS port of the DSLAM.
Case #2:
the pair has its RING signal shorted to the Ground (GND). Make sure the pair is properly
inserted in the punch-down block. You should also verify the pairs are properly connected to the
cross-connect and / or the POTS port of the DSLAM.
