TVP-221H User’s Guide 

 

 

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.

1.  Now let’s make a call to your PBX extension. Pick up the handset 

connected to the FXS port and dial ‘201’, you should hear a dial tone 
(This means that TVP-221H picks up the line connected to your PBX). 
Then dial ‘316’, your extension handset should ring right away. 

Hint 

This guide only uses the default values. Once you are familiar with 
the dial plan set up, you may design your own dial plan.  

TVP-221H has two FXS  ports. An FXS port can connect to an analogue phone 
directly, and a FXO port can connect to a PBX system or CO line.
