Yes I have tried this. But it does not tell me the distance to my exchange, it does not tell me the line noise ratio's. Not Telkom, and not the ISP can tell me this !
It says I do have ADSL on exchange and that I can get ADSL. I live in a small town. Our next neighbouring town (even smaller) is 89kms away. I know ADSL is only effective up 4,5-5km's but...
Please guys, do yourself a favour. Ask someone who lives in the UK or Netherlands how a line test is done by your potential ISP.
If you don't know, here is how ine find out what line speed one can get in an EU country:
1. Call your potential ISP's sales.
2. Give your landline number where you want the ADSL installed.
3. The sales guy/girls will probably tell you "Your copper cable is 1,9km or 2,4km (whatever) and you can expect to receive up to 17Mb downstream and 1,5mb upstream."
It is number 3 that no one can tell me.
