Thanks to the generous replies here, I have worked through a couple bugs on the way to getting this used DK16 system running here, and I think I have just one issue remaining.
There is a KSTU and a K4RCU in the base unit (there is no expansion unit) to support standard devices.
When I hook up a standard phone to one of the standard ports I have wired (at station 18 and 19), I hear a steady tone, but it's not a good imitation of the CO office dialtone. Another post here notes that standard devices get intercom dialtone, so the pitch or quality of the tone doesn't trouble me too much, but it won't let me dial. The LCD display records my keypresses, but there is no dialing, no line ringing and no connection.
The only programming I have done is Prog 90, 92, 03, 81 and 87. I entered all the default values for Prog 03.
Can any of you pros nail it down from what I've said?
