We have a somewhat potentially exotic challenge to try to solve. Will anyone admit to having tried this sort of low-cost solution in a production networking role, leveraging only voice grade cable?

For extreme circumstances when it is not feasible or possible to install proper network cabling, we use a solution similar to what you linked. It uses DSL technology over phone-grade copper cables. We have been satisfied with it's performance and reliability, but we still try not to use them if possible. http://www.ethernetextender.com/ Cheers!

Do you mean installing dsl-type standalone devices that extend Ethernet across cat3?  Absolutely.  Ideal, no even close.  Cost effective,simple to deploy and reliable, priceless.

Old Cisco LRE gear works well, but don't think you can get it anymore except on 3rd party market (price should be right about now if so).

There's a closet switch or two (aggregation) and little CPE "hubs".

I've used a product from Netsys, not the exact one you linked to, with very good success although I will say that it was not on campus.  It was used to link 2 buildings connected together with an existing shared POTS line from the local telco.

Hi, Lee.  We needed to get a network printer and a couple of thin client terminals working in a maintenance shop that only had our in-house phone lines going into it.  We purchased an older version of what Netsys now sells as their NVF-800S unit and put that next to our PBX, and we put (again) an older version of what’s now sold as the NVF-200R in the maintenance shop.  We could have just used a pair of 200R’s, but anticipated using this to replace some wireless bridge units elsewhere on campus – however we had an opportunity to run fiber instead.  I had to find the order invoice to get the model numbers, and was surprised to find that this was way back in 2004.  The units have worked flawlessly since day one.  I cannot comment on bandwidth capacity, because a printer and two thin clients don’t use much, but these things have been rock solid for us in terms of reliability.  I do recall reading that speed goes down as the cable distance increases.  The run to our maintenance shop is about 1300 feet.

 

Good luck with your project!

We did something very similar at my last employer.  Our run was only ~500’.  Never had any issues with it.

 

 

Fyi,

It’s funny you posted this.  We JUST removed an old Tut Systems box that was doing exactly this in favor of a pair of Ruckus point-to-multipoint wireless bridges.  I went from ~12Mbs to ~280Mbs.  (And to add to the irony, I just made a post that hints at a post you made a year ago about a Network Monitoring paper you were working on).

We do not use the particular product, be we have been using a pair of DSL bridges in different locations over very old phone cables. We have it in 2 locations and have never had any issues. The limit on our setup is 10 meg and it's been working for over 8 years without any issues.

It's this product specifically:
