Symptom
For OHP equipment connected to an FXS port, this Troubleshooting refers to the ATA front-panel FXS LED for the FXS port you
are using for the OHP equipment. When the equipment is properly installed, and everything is configured correctly, this is the
behavior of these LEDs:
OFF: There is no paging activity.
Flashing GREEN: A user has initiated a page.
Solid GREEN: A device other than an OHP (such as a fax machine) is connected to the FXS port and has gone off hook.
We also use these LEDs to help diagnose problems.
Single-zone OHP on FXS is
not working.
Troubleshooting
Synapse Administrator's Guide
Probable Cause
Single-Zone OHP Connected to an FXS Port
The OHP may not be properly
installed.
Corrective Action
Test basic OHP functionality.
a. Connect a corded phone to the FXS port configured
for paging.
b. Page all extensions and verify that the phone rings
when paged.
c. If the phone does not ring, there is a problem with the
WebUI configuration or the installation at the ATA.
d. If the phone rings, the configuration allows
communication with the OHP, verify your paging
equipment:
Does it have power? Is it turned on?
Refer to your paging equipment
documentation if there are still problems.
