To enhance the capabilities of national long distance telecommunication and to establish long distance telephone service in the strategic border areas, domestic satellite earth stations were implemented starting from 1991. VSAT systems were introduced in later days. The successful implementation of the domestic satellite communication systems and VSAT brought in special contribution to the development of social and economic activities of the people, especially for those living in remote and far-flung areas of the country. All the domestic earth stations and VSATs are linked with THAICOM3 using a quarter of a transponder.
Cellular mobile telephone system (Analog AMPS 800) was first started in Yangon in December 1993. Addition and upgrading for 5000 units by introduction of Digital AMPS is completed in early 1997 and the total of 7000 subscriber units are now fully occupied. Implementation of Digital AMPS system in Mandalay for initial 1000 units is completed and has been commissioned in March 1996 and the capacity is now fully occupied.
For international communication MPT had continued using standard B earth station till February 1994 with 60 telephone channels connected to seven countries. MPT launched standard A satellite earth station with new international gateway switch in March 1994 and the system was operating with 866 digital voice grade circuits destined to 16 via gateways (14 countries) at the end of March 1999. The introduction of standard A earth station and new international gateway switch enabled MPT to provide easy access to International Direct Dialing Service. The system can now be expanded up to 1020 international trunks.
As the new international gate way switch is a combined digital switch type, this is also used as a national transit switch in Yangon . By implementing one local-cum-national digital transit switch in Mandalay , MPT had established second transit route in between Yangon and Mandalay and thus smooth connections of transit calls were realised.
By making use of KEDCF loan from Korean Government installation of 3 new digital exchanges in three provincial towns for 7000 lines in total had been carried out and were commissioned in April 1994.
Starting from early 1995, MPT had introduced (WLL) Wireless in Local Loop automatic radio telephone system (TDMA) for 1000 telephones in Yangon and 700 telephones in delta area. 500 more telephones were added in Yangon during the same year together with 250 telephones in Bagan. The same systems are in use at Hpa-an, Mandalay , Mawlamyine, Hanzada, Shinmataung and Kanbauk. In addition, MPT in 1996 installed card phones in Yangon and Mandalay and plans to bring in more in coming years . Digital European Cordless Telecommunications (DECT) radio telephone system is also introduced in 4 towns and altogether 2900 lines are in use.
MPT has achieved a considerable growth during the last eight years period; but it is still far from fulfilling the ever growing demand for all kinds of telecommunication services and MPT will go on planning for a rapid growth to coup up with the demand and also will be planning for the modernization of the existing services. Such plans will constitute utilization of up to date technology telecommunication equipment for new installations and phasing out the existing old manual exchanges and analog equipment.
MPT on 17-10-97 commissioned CDMA radio telephone system. Myanmar is the first to introduce this new technology in South-East Asia . The system was started in Yangon equipped with a total of 3,000 telephone instruments. Expansion for 20,000 including 3,000 for mobile application, has been done.
In fact MPT is using limited fund for the expansion of its network. Some of the works were carried out by making use of the fund raised by the public in some areas. Small and medium size projects had been implemented using supplier's credit with reasonable financial terms.
X.25 packet switching system was introduced by making use of Siemen's EWSP with 300 subscriber terminals in Yangon and 80 subscriber terminals in Mandalay . MPT is now operating Internet E-mail service 138 leased line users and 5,510 dial up users in Yangon and Mandalay .
The present international gateway switch and the standard A satellite communication are the only available system to be linked with other countries. The alternative route with better performance MPT in SEA-ME-WE3 international optical fibre sub-marine cable is already activated. Cable landing station in Myanmar and international gate way switch in Yangon will be linked with terrestrial optical fibre transmission system.
GSM system contracted 70,000 in Yangon and 30,000 in Mandalay is now commissioning.
MPT is now commissioning digitization of existing analog exchanges in Yangon, Mandalay and Taungoo and Pyay (Total 55,000 lines) with Shanghai Bell Co., Ltd.
