1. What is the difference between BSNL Exchange and BSNL NIB? Is bsnl NIB in any district a kind of big exchange headquarter for all small exchanges in that city or in that district?

2. Is NIB present in every tier-2 and tier-3 city of a district (i.e., multiple NIBs in a single district) or there is only one NIB technical headquarter office in each district of any state who provide internet to all nearby exchanges in that city or district?

3. How can any bsnl customer find address and contact details of BSNL NIB in its District?

4. Who actually controls our bsnl DSL broadband or FTTH's profile settings and Speeds and who is responsible for rectify the other technical issues? Local BSNL Exchange or only District NIB office?

5. Is NIB office in any district bound to provide customer service directly to customers if any customer call to them or it is only answerable to bsnl exchanges or bsnl customer service center offices?
 
6. Also what actually is BSNL SSA (Secondary Switching Area) and how it is different from the Bsnl NIB in that district?
