ISDN MODEM

The ISDN Modem OMNI, NET support PPP Multilink Protocol, allowing for communication with ISDN devices at full bandwidth of up to 128Kbps. Bandwidth allocation protocol (BACP) provides added flexibility through the PPP Multilink Protocol. Bandwidth on demanding automatically bundles two B channels with the help of BACP. Which evaluates data traffic and automatically adds and drops the second B channels needed. Call-Bamping enables users to make an analog call when two B channels are in use by dropping second B channel.

Two analog ports are also featured which allow simultaneous use of two analog devices such as telephone modem and fax machines. For Ex. User may send e-mail while talking on the phones, or the web site while sending a fax.

The Multi-Auto feature automatically detects and accepts incoming calls for PPP V.120, V.110 and X.75 freeing the users from manual protocol configuration. The Multi-Auto feature also automatically answers and identifies calls as analog or digital and routes from them accordingly.

Also DTMF and pulse dialing recognition, but in speaker, LED status indicator and multiple subscriber setting are added features. The modem is compatible with all popular operating environments like Windows 3.1, Windows 95/NT, DOS, UNIX, Macintosh, OS/2 and Novell.

Camera for Video Conferencing

The camera used is a desktop, which is ergonomically designed featuring the flexibly of computer mouse.

The practical Soft base unit and High base unit (optional) allows to aim the camera in every direction whether hand-held or free standing, without the difficulty of release buttons.

The camera is equipped with a variable focus lens .The focus can be adjusted manually from a distance of approximately O-cm (macro) to infinity.

A microphone is integrated into the camera to give live audio.

The output signal is CVBS according to the PAL or NTSC standard, depending on type of camera.

Focus range:

It is possible to focus on extreme short distance (approx. 0 cm) by rotating the lens in the desired direction. Sharp image can also be had within a wide range by aiming camera at an object on distance of more than 5meters and rotate the lens until sharp image is got. In this case the camera is in focus from O.6 meters till infinity.

Amplifier Card:

The Amplifier is Class B Power Amplifier operates with a DC Power Supply .It has a good input sensitivity with a negative feedback.

Working Principle of the Amplifier:
