Indosat's Backbone (2)

I've just found another version of Indosat's backbone. For me it looks a bit better than the previous one, though some links might still be not so accurate.

Jakasusi, Jasutra & SKKL-JS

Below are several domestic submarine fiber optic cable systems owned by PT. Indosat.

Jakasusi (JAva KAlimantan SUlaweSI) :

• Jakasusi segment 1 (B1) connects Banyu Urip (Jawa Timur) to Takesung (Kalimantan Selatan)

Indosat's Backbone

In this post I just want to put some additional information (maybe "another view") of the Indosat's backbone mentioned in the this post. The map below was presented by Indosat in Apricot conference several times ago (2006, in Bali I guess). Does Indosat use any consortium's cables (SMW, APCN) just to link to Singapore ?
