I dragged some extensions out and plugged into it, they work fine.
I can bounce inside calls around pretty easily. The extensions appear to have
been numbered in an arbitrary order though. I'm gonna read the DLP books and
see if I can change that without the MAAP box. Also, as for the 6 loops on
the console - That's 6 lines for the console itself. The console can have 6
conversations going on it at the same time. The PBX seems to be able to switch
as many calls as you have outside lines for. It does use relays, if I opened
the front cover and dialed I could hear it click as it completed the call.
I also let it sit and run for about 5 hours while we played a card game upstairs
and it worked fine after running awhile. (But after about 10 minutes I did get
a minor warning because the CO wasn't talking to me, which makes sense...)
The next fun things to do are reprogramming the system to some sane values
AFA line numbering and the outgoing lines, then finding a way to back up the
OS tape, and the trying to connect it to the world.

Ah, ok. Makes sense.

That's typical on calls to outbound trunks, but it's clicking on station
to station calls (i.e. internal)?

What do you mean the "CO wasn't talking" to you? I'll translate this
to
mean the system sensed that it didn't have dialtone or line voltage on the
trunks that are programmed currently.

How did you find out the extension numbers, and what are they?

[Clicking on station to station calls?]
No, I don't think it did, but I'm pretty sure it clicked once when I called
the console. And dialing 9 made it click a couple times.
[CO wasn't talking to me?]
Not sure how it determined it, but it sensed the CO wasn't there.
(Minor Network Alarm is what the panel indicated.) Probably what
you said.
[How did I find extension numbers?]
The console seems to have an internal-only Caller ID, because when I called
the console, there was a small LED display that lit up with the extension
number. I know it's the extension number because if I dial it at a dial tone,
it rings the extension I dialed.
And now for the next screw: I need the MAAP device. Almost all of the
administration-type functions need it. I'm going to go back to the site
and see if I can find it, but I'm pretty sure I got everything that was
there. It does look (from the diagrams in the schematics book) like the
little terminals the DEC F-S people had (the one pictured in the RA81
manual, at least), but I can't find a pinout for the connector for it.
The connector for the MAAP is on the breaker panel - Maybe if I see how
many lines are in the back of it... Maybe if I'm really lucky it's just
a serial device!

That's normal for outbound calls. That's the relay going "off-hook" on
the trunk side.

Well, generally a minor alarm on a switch can mean a lot of different
things. How do you know for sure it is because you don't have any trunks
connected to it? Sometimes a minor alarm is triggered by default after a
power fail (or any time the power is removed).
The switch could be capable of detecting the presence or absence of live
trunks on the ports where it's programmed to have trunks. It simply tries
to sense any current on those ports.

Aha. That makes sense.

Probably. You might want to try fishing for clues on comp.dcom.telecom
and comp.dcom.telecom.tech.
