All Exchanges

The following two maps show all known exchanges and their enablement state.

As previosuly discussed exchange enablement is indicated by an orange hue. A green hue indicates that the exchange is enabled & supports 10Mbps broadband. A red hue indicates those exchanges which are currently not known to provide an ADSL service.

As can be seen Cape Town, Pretoria/Jo'burg and Durban have a large concentration of exchanges. The Northern Cape is sparsely populated with exchanges, though one may surmise this reflects the demographics of that area.

Non-ADSL Enabled Exchanges

The following two maps show the exchanges which are currently marked as not enabled for ADSL.

Interestingly quite a number of exchanges which are not enabled for ADSL are also based in the main metropolitan areas. This is a result of pockets of non-enabled exchanges in a heavily enabled area. For instance there are a number of exchanges which are not-enabled in Benoni, Gauteng. These non-enabled exchanges tend to belong to smaller villages situated near a large city or town.

As demonstrated through enablement statistics Free State, Limpopo, and the Northern Cape have a large number of exchanges which are not enabled.

ADSL Enabled Exchanges

The following two maps show the exchanges which are currently marked as enabled for ADSL.

When it comes to these exchanges a great number in the metropolitan areas have been enabled. That said there are a number of enabled exchanges in sparsely populated regions. These tend to be large towns situated in the countryside such as the Cradock exchange in the Western Cape. This is not always the case, take the Williston exchange in the Northern Cape for example. Williston is by no means a large town or close to many smaller subsidiaries yet it has an ADSL enabled exchange.

As demonstrated a large number of South African exchanges are ADSL enabled. Though it is by no means apparent the criteria used for deciding exchange enablement.

10Mbps Enabled Exchanges

The following two maps show the exchanges which are currently marked as enabled for 10Mbps ADSL.

As few exchanges are 10Mbps enabled it is difficult to perform a thorough analysis of this domain. Even a cursory glance reveals exchanges based in the main metropolitan areas are being enabled for 10Mbps. Gauteng, Cape Town, Durban, Port Elizabeth and Bloemfontein (sparingly) are the only recipients of this service.
