SV8100 Drops all phones (they go dark) flashing red lights on switch, red light on PRI swich

(OP)
Hello all,

New here.

I have an NEC SV8100 (1 of 3 at my sites). For no reason, my switch will drop all the phones (they just shut off) then my switch will just blink red. I also notice my Adtran PRI modem will have a red light. The switch is accessible via web browser. I usually power cycle the switch and modem. This usually happens once a week.

The System Alarm shows the following...

Things I've done so far...

1. Update software on phone switches.
2. Upgraded copper PRI to Fiber PRI.
3. Replaced network cable to phone switch.
4. Replaced X/O cable from switch to PRI modem.

All the things I've done has improved the issue (it was once/twice a day to now once a week/2weeks).

I am actively looking into a new system. Also, this system is inhereted.

Thank you!!!!
