Description
The Ministry of Communications has been concentrating its efforts on modernizing the nation`s communication system to keep face with the Government`s over-all economic development and national modernization program. As a fruition of this effort, the national micro-wave toll network will be opened for the public service on December 21, 1967, thus setting a milestone in the telecommunication history of Korea.

Micro-wave communication is a modern means of communication which utilizes electro-magnetic waves of over one thousand Mega-Hertz and a micro-wave system is capable of transmitting several hundred telephone calls at a time with sound quality as clear as live voice without being affected by weather conditions such as rain or storm. This ultra-modern communication method has also many other advantages that offer greater conveniences to its users. Subsystem No. 1 comprising 708 circuits will be first put into operation to link cities of Seoul, Taejon, Cheongju, Taegu and Pusan, marking the beginning of the micro-wave communication age in Korea. This initial opening of subsystem No. 1 will be followed in due course by subsystems No. 2 and 3 which will connect Seoul with other cities in south-western and north-eastern districts of the country, providing a total of 1,368 telephone lines for use of the public communication. This system will also provide 132 circuits for telegraphy, 20 for program transmission and 1 television relay.

A commemorative postage stamp will be issued to celebrate the occasion, reassuring that the Ministry of Communications will continue its efforts to further improve its communication system to meet the demand from the rapidly growing industries.
