Hi everyone,I am about to apply for BSNL landline and Dataone. I got the application form from the local BSNL office. In the form, they have the option of some "internal wiring required" ?What is it actually ? I mean, what exactly they do in internal wiring. Is it worth opting for it ..and any advantages? And what will be the total installation cost...incase i apply for Phone instrument & internal wiring.* I live in a Flat appartment. If that has any relation to internal wiring.Any info..appreciatedThanksNimesh
