PT. Telkom has renewed their long distance transmission infrastructure in Java island since 2004. The project was called "Telkom Java Backbone Network" - at least it was the name their supplier (ZTE) called :-D

• Nov. 2007, ZTE inked contract of RMJ SDH backbone network TK project to build SDH backbone network in Sumatra Island and deliver turnkey integrated solution to OSP. Once deployed, the network will cover 9 major cities in Sumatra Island.

Other notes:

Built by ZTE ultra-long-haul DWDM equipments ZXWM M900 and 10G/2.5G SDH equipments, the network covered Java Island’s most major cities like Jakata, Bandung and Surabaya. The network has gained the customer’s approval and trust for its ultra strong stability and high reliability since its completion in 2005.

So far, Telkom’s most backbone traffic among major cities in Java Island is carried over Java backbone network. In addition, Telkom has leased a large amount transmission bandwidth carried over Java backbone network to other operators without backbone transmission networks.

Java backbone network has been the core of Indonesia’s transmission networks, further consolidating Telkom’s leading position in domestic communications industry.
