I'm 670m from exchange according cable route, SDC is like 15m from my gate though, TelkomZA guy said they installed a ISAM at my exchange
Now it depends on what line cards are installed in the ISAM. ISAMs can support, from ADSL to VDSL line cards. It is an open question whether OpenServe will convert to VDSL2 and its variants given their commitment to deploy FTTH.
The whole debate is almost totally dominated by what technologies OpenServe have decided to deploy in an exchange area and what their upgrade path is for that exchange. It is not something users are able to dictate and request.
The whole upgrade path regarding xDSL technologies has always been about:
(1) Increasing the data rate capabilities
(2) Increasing the reach over which xDSL service can be provided
(3) Increasing performance over poor copper connections.
