Warning:
It would be against airtel terms and conditions
If your neighbours do not object, Airtel may give you an overhead line from your friend's junction box.
You have to take a parallel phone connection and then use
ADSL splitter , modem, and use your friends''s ID and password. If the connection to original user's junction box ( locked) is OFC, may be there could be a loss. Test phone. then BB.
BSNL limit for telephone extensions about 2 KM. ( which they also give from their main junction box(POLE) only )
In my flat Airtel refused to run a parallel connection( 30 feet) from junction box, to another part of my OWN flat, and only ONE BB connection can be used at a time. ( extn given: distance 100 feet from present original connection free of cost.).
Para two:
