In 1982 the B Standard Satellite Station became fully operational and tele-traffic increased tremendously. A more powerful A Standard Satellite Station followed in 1983. After the country gained independence in 1984, TelBru became increasingly active. As one of the six departments under the Ministry of Communications, TelBru facilitated the development of telecommunications by developing an impressive range of domestic and international voice, message and data communication services.

To connect all the EWSD SPC equipment, TelBru invested in radio digital Time Division Multiplex (TDM) plus transmission equipment including fibre optic cabling.
