Father of the Nation Bangabandhu Sheikh Mujibur Rahman formed the Telephone Industries Corporation named “Telephone Industry Corporation Limited (Tesis)” on 24/04 1973 with the idea of ​​far-reaching development. Tesis is gratefully remembering Bangabandhu Sheikh Mujibur Rahman, the best Bengali of all time.

Earlier, in 1986, the organization was formed in Tongi in a joint venture with Messrs. Siemens AG of West Germany. In the post-independence period, Tesis was producing and setting up EMD telephone exchanges, analog PABX, fax machines, DP / CT boxes, cabinets, telephone sets to meet the demand of the country’s telephone sector. After the brutal assassination of Bangabandhu in 1975, that progress was not only hampered, Tesis gradually turned into a sick industry. From there, Tessis has been transformed into a digital device manufacturing / integration company by participating in the “Digital Bangladesh” building program of Hon’ble Prime Minister Sheikh Hasina, the dreamer and architect of Digital Bangladesh in 2006. The Hon’ble Prime Minister inaugurated the Doyle brand Tesis Laptop at the Bangabandhu International Conference Center on 11 October 2011. The beginning is the entry of Tesis in the digital sector. One by one, Doyle brand desktops, notebooks, tabs, biometric devices, multimedia projectors, sound boxes, smart pre-paid energy meters and other digital devices have been added to Tesis’s product line.

Telephone Shilpa Sangstha (TSS) Ltd. was initially established in the year 1967 with the nomenclature of “Telephone Industries Corporation” under a joint venture agreement between the then Government of Pakistan and M/S Siemens AG, West Germany. After the independence, Telephone Industries Corporation has been incorporated as a limited company with its present name Telephone Shilpa Sangstha (TSS) Ltd. under the Companies Act, 1913, and under a fresh agreement with the other part of the joint venture M/S Siemens AG, West Germany in the year 24/04/1973.
