PhoneLab Benchtop: H2TU-C (and H2TU-R) First Powerup

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).
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.
(caution, video contains loud ringing)

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
