Overhead Paging (OHP)
OHP General Troubleshooting
Overhead paging (OHP) is not working.
Probable Cause Corrective Action
You don’t know whether your
OHP is single- or multi-zone
and whether it needs an FXS
or an Audio-Out connection.
 There are three possible configurations for OHP:
 Single-zone paging connected to the AUX
OUT jack.
 Single-zone paging connected to one of the
two FXS ports.
 Multi-zone paging connected to one of the
two FXS ports.
 Select the appropriate configuration for your
specific paging equipment. See “Overhead
Paging Overview” on page 22.
 Refer to your OHP product documentation and
the respective troubleshooting section below.
The paging equipment, the jack it is plugged into,
and the WebUI must all match.
The OHP may not be properly
installed.
 For OHP equipment connected to an FXS port,
verify WebUI configuration:
a. Connect a corded phone to the FXS port
configured for paging and verify that the
phone rings when it is paged.
b. If the phone does not ring, there is a problem
with the WebUI configuration or the
installation at the ATA.
c. If the phone rings, the configuration allows
communication with the OHP. Verify your
paging equipment. Does it have power? Is it
turned on?
 For OHP equipment connected to the AUX OUT
port, verify the correct cable connections. See
“Connecting an Overhead Paging System (OHP)”
on page 45.
Refer to your paging equipment documentation if
there are still problems.
