RQ-3: BSNL modem, no back-up?

Of late the lights in the BSNL modem go off whenever power fails, and in the interim before DG power comes on, phone and broadband do not work. BSNL modem back-up doesn't seem to work when power fails.
Would anyone know why this should happen ?

Residents Question (RQ): Why, only Airtel TV ?

Someone who moved in recently at F Block wants to know why we have access only Airtel TV channel at Mantri Synergy . She says the cable TV network available elsewhere in the city costs only Rs.150 monthly. Her point is that Mantri Synergy residents should have options.
(Residents at Mantri Synergy,and those in emerging residential communities elsewhere on OMR are welcome to post questions online)
