"Diamond's solution is quite different, it actually use the 2 lines for 2 different purpose. It is specifily desgined for web browsing, using one ling for graphic and one for text transmission." - very clever solution, if it works.

Graphic and text are coded into bits (0 and 1) and mapped to signal waveforms then sent through phone line. How do you know which bit belongs to text and which belongs to graphic? 2 lines merely means you have twice of bandwidth so you can send twice of amount of information. USR had this technology at least 8 months ago.

Diamond's bonding product:

Andy Chu comments, "I heard that Diamond's solution is quite different, it actually use the 2 lines for 2 different purpose. It is specifily desgined for web browsing, using one ling for graphic and one for text transmission."

I hope not, and I think this unlikely. At what level within the TCP/IP stack can connections for the two different kinds of files be separated? No good place, as far as I can see. And why bother, anyway.

What they're almost certainly doing is the same thing that just about every bonding vendor is doing, providing two channels for the data to pass over, which almost (some overhead, of course) doubles the throughput. This uses Multilink PPP. This feature requires support at the ISP... I'm not sure who (if anyone) supports Diamond's product, but it shouldn't be hard. The only problem, not always simple, is making sure that the two calls reach the same hub... this gets trickier when one of the two calls is made only under load.

Here's a fairly unbiased reference on the whole thing:

My thoughts, of course,
