How is PNG Telikom connected to the rest of the world?
Two international gateway telephone exchanges diversely located in Port Moresby and Lae provide international connection to the rest of the world on digital circuits via satellite and submarine cable. Majority of these connections terminate or transit through Australia via the Telstra and the Optus networks. Most of the traffic to Telstra is routed via the Australia-PNG submarine cable which was enhanced with the addition of digital modems in the mid 1990s. Other Telstra circuits are routed via the Intelsat satellite. International connections terminating or transiting on the Optus network are routed via satellite. Earth station facilities at Gerehu and Lae provide direct digital connections to the Optus network via the Optus A2 satellite. This arrangement enables international calls to or through Australia to be routed via the Telstra or the Optus network. Telikom also has direct digital links with other major international traffic destinations via the Intelsat satellite.
