What I mean is that you mention Telstra bandwidth being inadequate. But your signal is still going down the same over-crowded Telstra wires even when you're with Adam!
Have I got that right? I'm not the world's most techy, so I'm probably missing some important concept here  |
Yes and No.
Yes: If the ISP you are signed with does not have their own equipment in the exchange, or does not have any free ports on their own equipment, then you will just be connected to a Telstra port. This is a wholesale agreement between Telstra and the ISP. Telstra bills the ISP, and your ISP bills you.
No: In most cases, an ISP has their own equipment (a DSLAM) installed in the exchange, and when you sign up with them, your connection at the exchange end is 'looped' onto your ISPs DSLAM. From this point, you are on your ISP's own network. If that ISP has sufficient 'backhaul', to service it's own customers, then you will notice very little slowdown at peak times.
Because the whole thing has a lack of investment, Telstra tends to be oversubscribed, and doesn't provide sufficient backhaul.
