Hint
You may also check the LED indicators on the TVP-221H. When it rings,
the related LED should flash. After you pick up the handset, it should
remain on and off when the phone is on hook.
Now let’s test your TVP-221H that is equipped with 2 FXO interfaces. Assume
you have one extension line with your PBX system, say, 201 as the extension
number, we connect this line to the gateway’s port 0 (FXO port), then connect
a telephone phone set to port 3 (for example) of the gateway.

Pick up your extension handset, for
example, 316 and dial ‘201’. After one
ring, you should hear a dial tone. Now
dial ‘204’. The telephone connected
to the TVP’s FXS port should ring.
Hint
If you do not hear the dial tone, please check the line impedance of
your PBX. For a TVP-221H with FXO port, you should find consult
with your PBX supplier or your System integrator for correct FXO
configuration.
