Agreed I would do the Adtran Total Access 5000. What you want is the "combo" cards. They combine a SIP FXS gateway and DSL port on one port, aka a Combo port. This would be the way to go, as it doesn't require external splitters to combine a DSL and Voice signal as you are talking about with two separate modules. If cost is a concern, look at Zhone. They have carrier class gear on the cheap. BTW, some of these chassis can support like 1000's of lines out of 1 box. Could do the whole village on a single rack quite easily.

We’ve been implementing similar DSL systems at large campgrounds for years. There are a huge number of high-density DSLAM solutions out there, and DSL CPE cost practically nothing. As you say, $25K is plenty to pay for the hardware, and a rack is plenty of space. The most time consuming part is wiring the existing POTS lines into amphenol connectors to plug into the DSLAM, 25 pairs at a time. In addition to Calix\Occam, Adtran‘s TotalAccess solution is worth looking into for their carrier-class support. -mel beckman On May 3, 2020, at 5:09 AM, Mike Hammett <nanog () ics-il net> wrote: If you were to outfit them with three chassis of Calix\Occam B6-252s, you'd be under $25k for the whole thing and get ADSL2+ speeds. You would need most of a rack to do it. Other platforms may or may not be more cost effective or a better solution.

The office runs voip, now i'm told i have to get phones to the workers because the <lots of explicit words> AKA previous owners of that business stopped the build when they ran into financial problems. So my plan is to utilize the existing many miles worth of copperpairs.I'm looking at throwing them into Versa Dslams that use pppoe pass through, throw in a mikoTik 1036 as pppoe server, and we got spare R710 i can use as radius server, and by my limited knowledge this works. OK data done, but... now all those pots out lines need to go somewhere that can handle 1700 or more lines, I am looking at either grandstream 48 port FXS gateways or sangoma vega 50 ports (which Ill use as 48 so theres a 1:1 match with dslams) the vega 3050 probably wont be used because they are more than twice the price of grandstream. But this all results in a sh1te load of 48 port gateways (power is not a concern), but wondering if there is another solution that is more cost effective? Seems the regular NEC's Siemens and so on might have an option but I can imagine it will be far more expensive than a bunch of individual gateways. This project is in my mind workable, but i've not done such a thing on a large scale. Those who have experience in this field care to chime in? is my method acceptable or not for such a project size? most pbx's I've done are only few hundred analogue lines where gateways are more suited and definitely more cost effective, at all our locations we use freepbx which works perfectly, and we know the beefyness of the box we'll need to install to handle this load, thats not a problem if we go down the gateway method. thoughts?-- Jeremy Austin jhaustin () gmail com
