A: SETUP PROCEDURE The Zydacron OnWAN Z340 is a PC card based CODEC specifically designed for IP (H.323) networks only. The plug in card requires a spare PCI slot in the users PC. Connectivity for the camera, audio, auxiliary video output and an optional audio headset are provided by a Breakout cable. Set up was straightforward. The camera (including an integral microphone) was plugged into one breakout cable and positioned on top of the PC visual display unit. Software was supplie

Mobility As the Zydacron OnWAN Z340 CODEC is a card within a desktop PC system it cannot be moved easily. To enable operation, each new connection at each new location will require the local IP address of the host PC to be updated. System Operation On launching the OnWAN software application the main Video Window opens. This window comprises three sections. 1. Control Toolbar at the top of the Video Window 2. Video Window 3.

switched off. The video window size may be expanded to 640x480 or even full screen but this does not increase the base CIF resolution, so the resulting video quality is then degraded accordingly. The Status Bar below the video window is made up of two sections and displays information on both the incoming and transmitted signals: 1. Connection status information 2. Active video and audio signals (Near and Far) 3. Audio level meters (Near and Far) 4. Connection status Light Emi

D: AUDIO TESTS (ITU standards only) As the second audio line input could not be activated on either unit, it was not possible to carry out tests 2 or 3. Test 1 was carried out with test signals inserted into the Headset Microphone input with the Echo Canceller set to OFF. The audio output level was then adjusted by the system volume control. Test 1: Frequency response (-3dB) (Insert a -30dB (Mic Level) signal at the local site, measure at remote site) G.722 G.728 G.7111 5
