That's normal for outbound calls. That's the relay going "off-hook" on
the trunk side.
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.
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.
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.
Aha. That makes sense.
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! -------
Probably. You might want to try fishing for clues on comp.dcom.telecom
and comp.dcom.telecom.tech.
