Actually the SS7 system, as well as most of the software and hardware are COTS components (afaik all are cots), so they are actually buying FOSS stuff without knowing. So as far as landlines go there is nothing to stop someone from building their own switches and exchanges and being 100% compatible to any other system. Infact that is precisely what one can do with a T1 line, a T1 card (dont remember the exact number) and asterisk / opensip / freeswitch / several other such FOSS software. If one were to string the trunk line, one could be a completely independent voice / data landline provider. Ofcourse the devil is in the details and one would be very hardpressed to rollout on a large scale without huge teams of very competent engineers - this is what the MNCs have done while everybody was sleeping, and they now command top dollars for the guarantee of successful and swift deployment. On the wireless front, the exact same can be achieved over wifi. and any wifi capable handset. Using USRP (a super FOSS software defined radio hardware-software combo) and a BTS IC costing $700 you can rig up a cell station. All the above ofcourse debarred to us serfs by the government, which has erected artificial capital barriers that preclude small scale deployments and heavily skew the whole arena in favour of moneybags. _______________________________________________ network mailing list [email protected] http://lists.fosscom.in/listinfo.cgi/network-fosscom.in
