At Gram Vaani, we are building telephony support through FXO and E1 cards. These are PCI cards that go into a computer, and so calls can be received/made through software itself. Therefore stations just need to get a phone line and then plug the line into the card instead of into a telephone or hybrid.
This setup gives us the advantage of being able to control the telephony channels to interpret DTMF signals. So we can actually make telephony applications such as press (1) to record an ad, or press (2) to leave an farming related question, or press (3) to request for a song, etc. Recordings for advertisements or questions and answers can later be broadcast through radio. A hybrid on the other hand will only give access to the input and output analog audio. The second advantage is that we are integrating all of this with the GRINS interface. So now the RJ can receive calls through the GRINS interface, and doesn't have to tinker with hybrid volumes and picking up the phone, etc. GRINS will also keep track of all recordings for advertisements, questions, comments, etc, so all the content can be managed centrally. The telephony service will be out in another month or so. Then stations just have to download GRINS and buy an FXO card. Single channel FXO cards are available for hardly Rs. 2000, and higher end cards can also be purchased if a larger number of simultaneous calls are to be handled. We will publish all these details very soon. Aadi http://gramvaani.org Dr Richie Rego SJ wrote: > we use oxygen mixer for on-air broadcast. It has built-in telephone > hybrid.
