In my experience at the ship, the patch panels have internal terminals for a power supply so you dont need a dedicated jack, but otherwise theyre fairly simple, and all our power supplies are external to the switchboards.
They do have large high wattage resistors, and rheostats for adjusting current. Basically they have a multi-selector switch for checking current on multiple circuits with one current gauge.

Hey thanks Tom! I did build a good patch panel into my black box “thing” . It’s got inputs on the side and breaks out to everything I need even with switches to take things out of circuit if I want to. I was under the misunderstanding that a navy patch panel might have an internal power supply or signal relay/regeneration that would solve a signal voltage problem I have. What I need is something to take an anemic loop signal and feed my patch panel it’s spinach. <image0.jpeg>

Anthony,
How many jacks do you need in your patch panel?
Do you need Tip/Sleeve jacks or Tip/Ring/Sleeve?
I use both,, but TRS is safer. I buy TRS plugs by the tens on eBay.
I build my own patching on Electrical boxes.
Don't forget a jack for a 100 ma meter. to check your loop current
If you don't have a meter, check out eBay.
I always monitor my loop currents.
You get a feel for how the meter should look
especially on RYs.
Attached pictures include 3 TS jacks with
shoulder washers and flat washers.
3 TRS jacks and 6 TRS jacks.
I can mount as many as 9 jacks on a 4x4 box.
The last picture shows a homebrew loop supply
and shows how I mount my meters.
