This post is mostly just for my own personal future reference.
This shows the settings and connections needed to connect a UTI-1 telephone interface to a PAP2 (or an analog telephone line)
Output of PAP2 connects to "station port" jack on UTI-1 and switch is set to "station"
when the PAP2 extension is dialed the UTI-1 answers produces a tone, and allows the caller to page over the connected amplifier.
