My question is still there. How can i use my ADSL Line for UPLINK and my SATELLITE line for DOWNLINK. Is it possible or not. If yes then can any one assist me is achieving such case.
Well, it is possible. That'ss for sure. In Europe several Satellite ISPs sell a system where you do the upload over a GSM or fixed telephone (dial up) network while the download then comes in through the satellite.
Off course this can be done as well with any other upload system (GSM, umts/g3, telephone, cable, adsl whatever.)
I think that the provider that arranges this has to configure that all requests for data (browsing, ftp, whatever) is routed out over the slow uplink path and the returns from their end to the satellite and then to the client. The client must have a router that both connects to the satellite receiver and the ´uplink´.
I think you can only manage this if you arrange the routing on the ISP side as well, which is impossible, unless you are this ISP yourself (and thus pay for all the satellite connections of your clients!)
Hope this is what you are looking for?
