another international gateway (DMS300 by TELRAD) in Naypyitaw.
(2) Present Status of Submarine Cables
The international submarine cable is the SEA-ME-WE3 (South East Asia - Middle East Western Europe3: completed in 1999) only. The adjacent landing points of this SEA-ME-WE3 are
Mumbai, India and Singapore (Landing point in Myanmar is Pyapon.).
(3)
Present Status of Cross Border Networks
The cross border networks consist the microwave radio communication and terrestrial optical
fiber cables. Outlines are given in Table 5.2-6. MPT is under planning to utilize a part of core
network by optical fiber cables (Muse, Tamu, Tarchileit, Myanwaddy) as international
communication circuit.
(4)
Present Status of Capacity of International Circuits
Number of circuits for international communications through satellite communications,
submarine cables and terrestrial optical fiber cables are given in Table 5.2-6. In Myanmar, the
submarine cables provide the widest bandwidth, i.e., 298E1 (596Mbps) for voices, or approx.
7.5Gbps for internet circuits. On the other hand, the satellite communication circuits provide
narrowest bandwidth providing 4E1 (approx. 8Mbps).

Present Status of International Circuit Switching Networks
Composition of the international switching networks is shown in Figure 5.2-8. The switching
equipment for international circuit are provided at five locations, i.e., at Ahlone station in Yangon
and also at the IGW station in Naypyitaw. Through these stations it becomes possible to provide the
redundant composition and to improve the reliability. The switching equipment in Yangon has been
renewed at the software switch providing a large capacity and having completed approximately
90% of the international telephone calls. The switching equipment in Naypyitaw using rather old
hardware and a new switching equipment is under construction and expected to be available within
the year 2013.
