What does a telkom exchange look like? A big blue box, a big blue building?

Any photos would be appreciated.

Jeepers, I havnt ever seen one of those anywhere.
 
They are everywhere, look for some green and blue boxes!
 
Ya i have one of those at the gate of my complex :)
 
cool thanks!

I'm going looking for my local this afternoon.
 
Usually the exchange is a nice smallish building on an otherwise unused plot with Telkom logos on the fence...
 
I've been inside an exchange building, when I was a student as a part time job installing stuff...

Rows and rows of machine and floors made up entirely of cabeling, just covered by a floor level of panels. But it was a decent sized building... unless that is the next step up from an exchange?
 
Yeah it is just full of racks and loads of wires that comes up from cables in the floor. There the cables, in a telephones case, are connected from the street to the digital side of the rack and thats where the link is between the street and the part that enables calls to go through.

The digital echanges are normally quite quiet, as opposed to an analogue exchnage where the "dialers" are making a load of noise for all the calls that are taking place at that time.
 
So wot r the little green and blue boxes then? I have those in my area. Loads of em! but always get told by telkom that there isnt space available for me. So i take it those green n blue boxes rnt used for dsl?
 
Sometimes there is a cellular mast installed on exchange building plots when then the exchange is well located as per the mobile coverage plans.

Many of the original base stations, when the mobile operators just started out (1995 I think), were errected at exchanges for connectivity reasons, reducing microwave backhaul links to a minimum.

I'm no expert, this info just from observation and common sense.:D
 
The exchanges are sumtimes "under ground", they access it via a man hole (Maintenance hole), usually on the side of the road, with a white (concrete) cover. The telkom techies usually put a fence around the hole when working on it. If you see a telkom van on the side of the road with a portabal fence that's probably where the exchange is.
