Scored an industrial phone meant for hazardous locations on eBay.
Took it down to individual parts, threw them in the parts cleaner, scrubbed, and now we have a lovely call box!
Considering painting the handset an outrageous color.

TIL ISDN was sometimes patched between equipment locally via DB15 plugs.
Like, it did seem weird that the T1 BERT had such a plug on it, but had previously chalked it up to some proprietary silliness.
Turns out, nope. It gets so much more wild west than wire wrap and bantam.

Aaaaaand now we have a baby little ADSL DSLAM in the CO homelab :3
ET&Y is now offering very competitive rates for home internet services (limit 12 customers only, actual speeds may vary). :bec_grin:
Really really need to pick up a telecom rack to stuff all this year into; the table is getting cramped and we don't even have the DSX patchbay, HDSL mechanics shelf, or -48V plant supply in there yet.

Other than some framing and signalling silliness on the span, we have a working circuit and channel bank now.

The silliness pervades. :bec_smile:

Well that's the first 66-block I've punched down in about 20 years. Let's get this T1 rolling :D

Wonder if there would be any interest in [FPV] streaming some retro CO phone lab tinkering.

In continued phone-nerdery: Welcome to the Tandem Straylight.
Let's get some old CO gear talking to each other :pixelheart: ☎️

It has been a good, silly, evening, filled with 66 blocks, phones, T1 circuits, and glittering hardware.
Need to order (find?) some plug-in surge modules for this building terminal.
Safe to say things are getting deeply nerdy, here.

CW: lots of nerd talk about dreamcast and phone lines with dubious delivery
In the service of totally overdoing some #Dreamcast #RetroGaming, I've successfully patched the #DreamPi gateway to be less useful. Buckle up, because this is a kinda long post with little in the way of delivery. :bec_smug:
Normally the DreamPi throws its modem into voice mode, plays a dial tone to fake out the dreamcast, listens to the digits dialed, and then switches to data mode and kicks off a handshake. Stays off-hook the entire time.
This makes sense if you're using an electrically-simple Line Voltage Inducer and a straight connection between the Dreamcast and the modem for minimum part count get-up-and-go. It's actually a really clever workaround.
My tweak adjusts the modem behavior such that it stays on-hook until it detects an incoming ring, then answers and jumps straight into data mode.
This change was made because presently we're using a Valcom DLE-200B phone line simulator which does provide 'local' tone, ringing voltage, and ringdown.
This necessarily means that we lose out on capturing the dialed digits, but it turns out we don't need those at all for pretty much any of the PPP-based games with central servers, and I'm not interested in playing anything outside of that scope.
So now we have a dreampi that can only work in PPP mode and it requires a line simulator to work correctly. Why?
All, ultimately, so that we can hook the DreamPi and two dreamcasts up to a TDM-based #PBX instead of the line simulator, wherein either of the latter can dial the former, thinking they're dialing Dreamcast Online Services. It goes through the whole ring-in process, which terminates at DreamPi, handshakes, and tunnels to Dreamcast Live -- getting us the goods.
And there's lots of Friday left to go :3

Hnngh, talk about an anticlimax. Been hunting down this IP Office chassis to install in the telecoms lab and it *seems* to have a dead internal PSU.
It's gonna get repaired, of course, but it just totally killed all immediate forward progress.

Laying this -48VDC distribution panel out. AHhhhhhhhh red ground feels wrong, and it feels *even more wrong* to bond it.

I know I asked this a while back, but I'm stubbornly going to keep at it.
There are more than a few entities on fedi that are into standing up old phone networks, ranging from military field comms, business PBXes, even homelab ESS implementations.
But I can't find a dedicated hashtag for the life of me, so I'm going to pick one and run with it.
#OtherNetworks is a great catch-all for the more esoteric, #RetroLab is broad but you get the idea, and #HomeLab is *really* broad.
#Boost maybe? ❤️

On the other hand, single- and dual- card enclosures for the modern high-density stuff don't exist. Not like they're not available on the market -- they were never made. That would be sorta silly for a high-density product.
There could be a market* for that.
And by market* I mean a very small number of #retrolab #othernetworks #phone nerds who might like to 3D print this shit or something.

Spent some time fighting the Tandberg C60 to play nicely with #asterisk tonight, but happy to report that we got there.
It really _really_ wants to use H323, y'all, and saving certain SIP parameters via the web interface is bugged to hell (like auth?) -- you've got to jump into the CLI and set the parameters manually.
Made tweaks to codec lists on device and pbx, and we have g.722+h263p SIP calls working.
Wrapped it up with a nice custom wallpaper bow.

Heya internet, I'm in search of tags and accounts of people playing around with:
* older enterprise networking gear
* telephony gear and labs, particularly CO equipmentSeems like the kind of thing one should be able to find on Fedi :-)
