@#%$@# forgot the list again.
Charles, haven't seen that specific problem, but if it
helps troubleshoot. Keep in mind that the stations
tend to be grouped internally in sets of 4. Like
01/02/03/04, 13/14/15/16 etc. The power and overload
protection is this way. A short on data pair for port
14 will also take out 13,15, and 16. Generally no
damage.
We had a d1232 with a 4port tvs100, every
once-in-awhile, the voice mail would shut down...
flashing power lite and all. After several trips (you
know, it was working once the tech arrived) we found
the problem. There was an unused extension jack in
the computer server room. It was there so the computer
dudes could carry a phone back there and talk to the
office to fix problems when needed.
The computer folks dragged in an old modem and plugged
it into the jack. Ocassionally the modem would dial
their office and dump an error list. The modem had
A-lead control on the yl/bk pair, that, you guessed
it, shorted the data pair everytime it called out.
it was station 13, and the voice mail was on 15 and
16!
oh, one caution, you can destroy the data transformer
in the pbx, if the customer plugs a 10baseT card into
an extension and leaves it there for more than 30
minutes. We had a computer dude do this thinking the
NIC was a modem. He used a regular 4C line cord from
the wall, to the nic card (an 8pin jack). The NIC
coil resistance it just high enough to NOT trip the
short protection in the pbx. So it sets there cooking
the data transformer, which will literally melt the
plastic case, then short the coil. On a kxtd, the
associated 4 ports die, until the transformer is
replaced. On a kxt, one of the three power lamps will
go out, and the whole system dies until the affected
card is pulled.
He didn't have enough sense to remove the cord after
he realized it would not work, if he pulled it, the
system would have survived. (Need a spare transformer
- a kxt dss card is cheap and has TWO spares ;-)
