Facility DC Open
- A DC Open condition is often caused by a lack of current flow on the DSL
loops. The condition should be resolved when an H2TUR (or H4R) is installed.
- If open is not due to absence of equipment, verify wiring in the H2TUR (or
H4R) housing. If still open, troubleshoot facility wiring for an open circuit.
Looking toward the CO, you should see approximately 190 volts across T/T1 and
R/R1 at any point. Also, if HDSL2 equipment is connected you should see a short
on both pairs in both directions. If not an open circuit still exists.
- If wiring and shelf OK, connect H2TUR at the frame and verify DSL sync can be
achieved. If not, replace the H2TUC and H2TUR one at a time to identify the
problem.
