Single-Zone OHP Connected to an FXS Port
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.
Cause Action
The OHP may not be properly
installed.
 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.
There may be a problem with
the paging equipment or its
setup.
 Verify your paging equipment configuration.
Check to see if the OHP system has settings that
need to be adjusted to work with Synapse. Refer
to your paging equipment documentation or to
your installer.
