I have been ranting on about ADSL being a 'last mile' technology, and that any ISP ought, by law, to be able to site a DSLAM in Telkom's exchanges, as has happened in European countries with deregulated telcom state monopolies. What we have is Telkom bundling Internet services with ADSL, when these two facets are really unrelated. Real ISPs cannot compete, or offer deals and bundles of their own.
I see that the ISP Association has a statement on this matter:
http://www.ispa.org.za/press19_03_03.html
"ISPA believes that ISPs should be able to locate their own DSLAM units at Telkom's exchanges, removing any need to rely on Telkom's IP network to relay the ISP's customer's information and reducing Telkom's anti-competitive cost advantage."
This is the only real fix to the problem.
