Recommended Tests

To sum up what it all means:

Combining multiple lines of dial-up increases bandwidth or the data carrying capacity per second.

Even if we can combine lines to achieve a bandwidth of say 560 Kbps it will be slower than a DSL of the same bandwidth because dial-up has a higher device latency.

Adding to this, the article in the link was trying to make consumers aware that manufacturers often boast about capacities of their devices but do not advertise on the performance of these devices with respect to latency. So if I am to choose among routers or among modems of the same capacity, I should choose one with the least device latency.

trogers: Except for a little variation in the examples the article made I basically agree with it.
Capacity is advertised as speed.
tommie gorman :DSL would definately be faster.But on the 56K the combined 2  56k lines would
would load faster because more data would be coming into the connection at once.I think it would test faster on a download test or upload for this reason.If the speed was measured from each 56K line seperatly then it would be the same speed as 1 56k modem on that line.The only bottleneck would be if the PC receiving the data could process all of it as fast as it was coming in.
I have never used a bonded modem system(shotgun) .I would like to see how one performed.With DSL as cheap as it is now when it is available it would be better performance for less money.But if only dial-up was available & cost wasn't a factor then a multiple line system would definately improve performance for some things.Probably not gaming though.
