Technology is by no means entirely human resource based. This concept interprets that technology is the analyzing and reasoning power which resides in the human brain, to create products or provide services.Technology is acquired through R&D (Research and Development) and results in scientific enhancement.Engaging in R&D also stimulates professionalism. No company can survive in fast progressing technologies (which create a limited technological lifetime of the product or service rendered), and competitive business without thorough R&D.

An important "by-product" of R&D activities in spin-off technology development, that is, by creating something, its technologies could be a base for other products or services, depending on the innovativeness of the researcher.

In 1992, the final prototype of a small capacity digital telephone exchange called STK-1000 was demonstrated to PT Telkom, who were the sole operator in Indonesia. STK-1000 is a telephone central office (CO) fully automatic digital switching equipment with a nominal capacity of 1000 subscribers. It can be installed with as little as 60, and expandable to as many as 3500, subscribers. STK is designed and implemented using advanced, state of the art, digital technology which in the future can be grown to provide full ISDN service.

As improvements occurred in components available in the market, technical updates were made to the switch. The company was striving to produce a higher capacity system, and now proudly offer a modular system called SENA. SENA is a family of digital telephone exchanges with capacity of up to 20.000 lines capacity. It allows, however, be sub-equipped with very low number of initial lines and can grow incrementally to the maximum capacity when requirements warrant ensuring economic investment outlay.
