[GreenKeys] Flecher TU 170 with model 15?

[Daniel Jones]

I have one of these in service.  It has a built in loop supply that can be directly wired to the keyboard/printer.  It can also use an external loop supply by disabling the internal loop (This is how I use mine now as it’s on a powered patch panel)
