Centre for Excellence in Telecom Technology and Management (CETTM) located in Hiranandani Gardens, Powai, Mumbai is the telecom training centre of MTNL, the incumbent operator of Government of India (GOI). It was founded in 2003 as one of the largest telecom training centres in India and amongst the biggest in Asia. The Centre provides extensive training to corporate employees, students, and MTNL's internal employees in telecom switching, transmission, wireless communication, telecom operations and management .

CETTM also conducts training in telecom, IT and management under the Ministry of External Affairs (India)- Indian Technical and Economic Cooperation (ITEC) program for telecom professionals from developing countries.


Indian telecom industry was closely held by GOI until liberalisation in the 90's. The telecom training and manpower development was delivered through:

  • Advanced Level Telecom Training Centre (ALTTC) at Ghaziabad. It was set up in 1975-76 with the assistance of UNDP to meet the continuing and long term need for high level technical personnel required for planning and development of ever expanding telecom network and service in the country. It also provides training facilities to senior engineering staff and instructors of other telecom administrations in Asian region.
  • Telecom Training Centre at Jabalpur, MP renamed as Bharat Ratna Bhim Rao Ambedkar Institute of Telecom Training (B.R.B.R.A.I.T.T.) from 30 May 1992 had its origin at Calcutta where it initially started functioning in the 1920s.[1]
  • Regional Telecom Training Centres (RTTC's) at Ahmedabad, Bangalore, Bombay, Ghaziabad, Hyderabad, Kalyani, Lucknow, Chennai, Nagpur, Patna, Rajpura and Trivandrum.
  • Circle Telecom Training Centres (CTTC's) in telecom circles.
  • District Telecom Training Centres (DTTC's) in telecom districts.

After the formation of two incumbent operators BSNL and MTNL from erstwhile DoT, RTTC's and DTTC's in their respective regions were allotted to them. BSNL retained control of ALTTC Ghaziabad and Training Centre at Jabalpur.[2] MTNL with operations in Delhi and Mumbai met its training need through RTTC's and DTTC's. In Mumbai circle the DTTC at Bandra and RTTC at Sakinaka served the telecom training needs initially.

CETTM Training Centre

Over the years MTNL felt the need to develop a training hub catering to both its Delhi and Mumbai units. Consequently, in the year 2003, MTNL established the Centre for Excellence in Telecom Training and Management (CETTM), with capex plan of over Rs 100 crore, at Hiranandani Gardens, Powai, Mumbai, replacing the existing RTTC's and DTTC's. CETTM has evolved as a key telecom training centre in Asia, expanding its sphere of operations beyond the originally planned internal staff and employees, CETTM now offers training to corporate clients, telecom professionals, students and academia.
