Does our Pana 1232 have a bad power supply? Walt 12-04-2006

I've never seen something like this before. We have a Panasonic
KXTD1232D and all the sets will occasionally "wink out," as if
they were all unplugged from the wall, then come back on a second
or two later. Any calls in progress are dropped. It does this every
few hours.

Last week it was doing this more and more often, ending with
the sets being off permanently. I power-cycled the 1232 using
the rocker switch on the side and that brought everything back
to life and it remained rock solid for a few days, then this started
happening again.

I checked all the connections, including the 25-pair pigtails into
the unit and they are all properly seated.

So, what do you think?

Power sags on AC circuit ? Put on backup and see. Weak power supply,
disconnect about a third of the sets for one day and see what happens.

Possibly a failing processor.

If you know how to do it check the voltages coming out of the power
supply while the system is 'down' and see whether they are up to specs.

Take care,

How many and what types of phones do you have on the system. Are there
any analog ports being used?

TD's don't like shorted data pairs and sometimes an old modem or
single line set will short the second pair and give the system fits.

I'd try to isolate all the extensions to maybe the 1st phone and start
adding the digital sets one at a time then any analog phones with just
two wires.
