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.

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.

Brian Russell talks about the big business of spying tech #spyware at #SobTec. Israelian tech companies like NSO with #Pegasus, unit 8200 of the #IDF
Brian is active in the BCN #phonelab and works at #IodeOS
Brian recommends #graphene_os as more secure mobile OS, paradoxically running on Google Pixel phones.

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

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