We have video conferencing unit (Polycom Video Station PVS-16 XX with PAL camera UISC Interface equipment.) along with camera for transmitting and receiving video and audio signals. Video conferencing is done through MTNL's ISDN lines. We have 4 ISDN lines of 64 kbps each. ISDN lines have been terminated into NT box. There is a IMUX (Multiplexer) connected between polycom and NT box. A switcher is used to select type of display. LCD is used to project the picture, which is connected with the Polycom. |
