With effect from 1st October, 2000, the incumbent government operator Department of Telecom Services and Department of Telecom Operations were constituted as a company under the Indian Companies Act, 1956 christened Bharat Sanchar Nigam Limited (BSNL) covering operations in the entire country except in Mumbai and Delhi Service Areas where the telecom operations were already transferred to a company, the Mahanagar Telephone Nigam Limited in 1986.
Born out of this vortex of change this niche organisation, the offices of the Controller of Communication Accounts (erstwhile DoT Cells) were created as a vital link between the Government, which after formation of BSNL had shrunk as a Department of Telecom at the Ministry level only, and its various field units and stakeholders. With a humble beginning performing residuary functions and staff policy of BSNL of the government at field level, the offices of Controller of Communication Accounts have over the two decades emerged as a focused organizational set up translating the various government assurances in to a definitive action.
The office of the Controller of Communication Accounts (CCA), Tamil Nadu is one of such units functioning as a critical professional interface between Department of Telecommunications (DOT) Head Quarters and its various stakeholders at the ground level on various policy issues such as management of license fee, spectrum charges, USO Fund, claims of BSNL staff e.g. GPF, Pensions to name a few. Within a short span of time, the CCA offices have carved out a niche for themselves by serving the different stakeholders of DOT – telecom service providers and in particular BSNL employees – and bringing them closer to DOT with their lean structure and professional working.
