atcomsystems.ca/forum Forums TDM Business Telephone Systems Panasonic Telephones & Systems All ports periodically resetting?!

Did a self-test on the UPS, it holds up the load no problem.. phone system doesn't screw up at all when switching to battery or back.

As for heat, it has always been in a relatively warm area, but lately it has been cooler than in the past due to AC improvements. It is certainly not all that hot there - perhaps 25c.

Jason, I've still seen UPS' act strange, (especially APC) even with passing the load test.
I would still by pass for a day or so and see if that's the problem.
I have also seen on some of the older versions where a short on the data pair of a station caused the whole system to act up..
It could also be the power supply in the TD1232 breaking down.
you may want to also try disconnecting all non essential phones for a day or so and see what happens then.

Umm.. here's an observation.. the system does this every time I reboot my workstation! I noticed the corrolation once, and then repeated a couple times to be sure.. (connected to RS-232 port for programming) damn! Windows/some service must sent something out over the serial port during startup that the system doesn't like. This is new.. I have had this setup for years without a problem.

Good lord.. well at least I found the problem.. apparantly something is sending out this outlandish string of gibberish at login-time;

[0:00100101010001000101]56[0:00100101010001000101]56[0:00100101010001000101]56[0

1010001000101]56!

(the exclamation point is part of the string)

having all this junk arrive at the RS-232 port of the KX-TD1232 causes the system to reset apparantly. Perhaps a buffer overflow or something in the firmware? interesting.. anyway, the solution is easy..

thanks everyone for your suggestions, and I will post if I find what piece of software is causing this.

Nice catch, Jason! Are you interested in a job in the Washington, DC area?

I read this post too late, and it would seem that you've found your answer. If it happens again, though, I would start counting sets. You've said that you're full, including a number of analog sets. You might be overloading the power supply. Some older sets can reallt drain the power to the point where it might reset spontaneously.

My $0.02

Ed; Thanks, but I don't think the wife would want to move to DC lol

Capt; relatively full, yes; 29 digital sets, 20 analog sets. But the kind of problem you describe I would expect to see start happenening shortly after adding another analog set, not spontaneously when no changes were made, no? This started occuring with no hardware changes made to the system whatsoever.

As it turns out, I uninstalled some apps I had installed recently for testing on my workstation; I believe it was VMware Player that was throwing out the junk on the serial port. It has stopped now. Nevertheless I will not be leaving it connected when not in use anymore!

Jason, you know when connected, you may be receiving the SMDR from the system to your computer.
I wonder if it's possible your computer somehow interpreted the SMDR as a signal to send a command out?
Just a thought.

I know what you're thinking.. but that string I posted, I obtained by connecting my PC directly to another PC via null modem cable and running Hyperterminal on the second PC, then restarting the first one. Basically just listening to see what was spit out. The string appears spontaneously on the 'listening' PC's terminal screen, whenever the first machine is restarted or logged into, no transmissions are necessary to provoke it..

Also, I could precipitate the symptoms manually in the phone system, by merely opening a terminal program session (SMDR data is visible) and manually copy/pasting the string into the terminal session.. the phone system would then do it's restart/go-crazy thing on demand
