TVP-224HR User’s Guide

Hint 

You may also check the LED indicators on the TVP-224HR. 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-224HR 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 ‘203’. 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-224HR with FXO port, please contact your 
PBX Supplier or System Integrator for further information

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-224HR 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-224HR 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.
