Bonding 2 ADSL lines

[Bloodshed_x3d]

Hey guys,

 

I'm getting another line put in by BT and I was told by them that if I wanted to increase the bandwidth and speed I would need to get a company to bond the lines.

 

Is this something that HAS to be done by another company? Or is it something that can be done by myself using pfSense or other hardware?

 

I have had a look online and I've seen Sharedband. FYI I live in the UK

 

Each line would be 75mbps and we'd have 2 lines.

 

Any help would be great.

I'm pretty sure you need to buy a services which allow to bond the connection, as just running two lines won't increase your over throughput but will allow more connection such as you can use 75MPS line and your brother/family member use other. So it won't bottleneck your line.

If you want to bond the lines, it has to be supported by the ISP, it is not something you can do by yourself. You can do load balancing yourself, which increases the bandwidth for multiple sessions, but does not combine the lines into one. So, you could have two 75Mbps downloads going, but you could not have a single 150Mbps download.

Not sure how helpful this is, but my ISP, Andrews and Arnold, provided and configured a box called a Firebrick which bonds two lines. However, I'm not sure whether these are commercially available, or even remotely user friendly! Linus did a video a while back (although he is in Canada) on line-bonding, so the tech may be the same. I haven't watched that since it uploaded, so it may just be a completely different protocol over there!

ADSL Bonding is part of the Spec for DSL. The ISP I work at uses it extensively. We are lucky to have 2-3 phone lines to most homes allowing us to bond 2 for the purposes of increasing speed. Broadcom Chipsets in various modems support bonding and it's as simple as enabling it on both ends. Typically the bonded speed is somewhat lower than the aggregate of the 2 individually due to overhead. 

 

The main point is your ISP does need to support/enable it. This technology works on all DSL from ADSL2+ and up. This includes VDSL and SHDSL.

Thanks for the help guys. I've thought about it and at the amount it is going to cost I've decided it isn't worth it
