Can you multiplex DSL lines together??

[Arkitech]

For some odd reason I've been wondering is it possible to combine the bandwidth of more than one DSL line together.

Lets just say that you had more than on phone line at your home, would that mean you could have DSL installed over each of those lines?

And if so can you somehow combine the 2 DSL lines for greater bandwidth?

What equipment or software would you need if thats possible?

What would be the max number of lines you could combine together?

Right now I don't think it is possible due to the asymmetric nature of ADSL. Perhaps symmetric DSL but even so, this is not like a T-1 line which has a precisely fixed clock rate (1.544Mhz) which makes time division multiplexing relatively easy. DSL modems sync at different data rates so this could make bonding/multiplexing difficult.

Finally, if it was done (and I'm not saying it is impossible), then the bonded line would probably have more bandwidth than the ISP backend is capable of delivering. Sure, you may have 3Mb/sec of downstream bandwidth, but you will never see that much day-today unless downloading from a fast local server right on the ISP internal network. (like a news server)

"this is not like a T-1 line which has a precisely fixed clock rate (1.544Mhz) which makes time division multiplexing relatively easy. DSL modems sync at different data rates so this could make bonding/multiplexing difficult."

Modem's can operate in multilink setup, and would likely have different sync.

I'm sure this type of technology isn't available for xDSL but I can't see why they couldn't develop a way to make it work.

I'm sure you could have 2 xDSL modems and two ethernet cards in your PC and do some kind of load balancing between the two (effectively doubling your bandwidth).

I was thinking something along the same lines.... I wanted to try and get a cable modem, and I allready have a DSL line... I was going to get another Linksys DSL/Cable router, and put them both into my 10/100 switch.... I noticed that in the TCP/IP settings that you can put more than one Gateway... Has anyone tried this... That should work..

Copper Mountain DSLAMs can do it with Netopia DSL CPEs. SDSL and IDSL only I think.

Hmmm,

They have a product you can put Tx, DSL, and cable lines into and get combined bandwidth. Not sure how expensive they are though. If anyone has more information on them let me know.

In most cases you can upgrade your DSL connection to a higher bandwidth by paying more money - if not from the Baby Bells, then by going to a 3rd party (Covad, etc.). It would probably be more economical to upgrade your DSL rather than pay for two connections and the equipment/software needed to load-balance between them.

Check DSLReports.Com for other providers.

if I could even GET DSL, I'd try it!

AFAIK, you can do it with almost ANY modem using windows software..

I have more info, I used to work there...it is too expensivve for the home user. It was an allright company to work for, I ran their netware server and their tech support department. I think that their xtreme product is going to be their next big market, (it used to be called FatPipe T1) but they need to bring the price down, but being that it is a full system I think that it will be hard for them. Their other software is great, but why buy something that win2k/me and 98SE give you for free? (ICS feature) and there is a use for their modem bonding feature, but with broadband rolling out...I think that the usefulness of modem bonding is coming down. I left the company in Aug. of 99...
