Well this is not entirely true, they are rolling out their MSAN's to support VDSL, yes this is an intermediate solution, but the MSAN can be configured to support multiple technologies simultaneously. Via cards they can be configured to run ADSL, VDSL, GEPON and Active ethernet fibre, POTS so you could argue that this is a step towards FTTx. All that would be needed for FTTx would be sufficient backhaul, fiber line card in MSAN and the fiber drop.
That's why it is called a Multi-service access node, multiple services from the same node. Telkom know that FTTx is where it is at, they working towards it, and their MSAN project is the first step.
