Norstar 8x24 KSU phones resync ocasionally

Norstar 8x24 KSU phones resync ocasionally

(OP)
I have a customer who reported to me that occasionally all/some of the phones on their system resync and the lights on each phone flashs. If they are on a call the call will be dropped. The phones are a mixture of M7324, M7310 and M7208. The KSU has one fully used 6-port copper expansion board. The software is DR5 and uses a 2-part NVRAM. The KSU is on an Oneac surge suppressor. There are about 85 phones in service as well as a startalk voicemail.

I still need to get a list of which phones/ports, if not all phones/ports, have the problem but do you have any thoughts on this problem or have you seen this before?

Well if it is some phones then could be an AMP cable or Fibre cable is loose or the module is pooched.

What do the Alarm codes say?

Given the age of this beast I'd guess the power supply was going. It could also be the software cartridge, so I'd try that first since it would be a much simpler replacement. I'd recommend getting them into a MICS as they can be had pretty cheaply these days.

Thanks for the replies.

I have started gathering data about which phones have this problem. I am going to try to pin it down to a station module first. The office manager just reported that while on a conference call her phone blinked (resynced) every few minutes.

Curly cord: This system uses copper expansion modules but they could have loose cords, I will check.

The customer was going to upgrade to a VOIP phone system so I was not too concerned about this problem. They just got some bids in and they could not swallow the price so they put the total phone system replacement project on hold. They will now more agreeable to the replacement of some of their existing phone system parts.
