E: DATA 

TESTS 

 

Successful data sharing sessions over H.323 IP networks were initiated between 
two Zydacron OnWAN 340 units. Sessions with a Polycom ViaVideo were also 
successful.

Connectivity with Other Machines

 (models listed with comments) 

 

Successful connections were made in each direction with the following CODECs 

 
H.323 

 
Tandberg 6000 
Polycom ViaVideo 
Polycom VS 4000 
Polycom 512MP 
NetMeeting Webcam 

 

 

Connectivity with JANET Videoconferencing Switching Service (JVCSS) 
 
H.323 
 

Successful connections were made to the Management Centre IP MCU, H.261 
Video and G.722 Audio. The audio level at the Management Centre was measured 
as peaking between 0 and +4dBm. Although there was no indication of the video 
coding in use as this test was satisfactory it does prove that the OnWan Z340 is also 
capable of handling H.261 video coded signals.
