DSX 160 Station Troubles - 06/24/15 06:32 PM
Hello,
My Customer's DSX 160 has been rock solid since installed in sept of 2012 with all new hardware. Trunks are 8 POTS lines behind good electronic fuse protection. All wiring is new. System is on a UPS and System is properly grounded.
Lately, the customer claims Line 6 dials line 1, and, some stations will intercom each other by themselves.
They have v-mail to email feature, so I have disconneted the Internet, so to not allow hacking, and, have by-passed the UPS.
There is no sign of water damage at the Unit or stations.
We have re-booted several times. All is quiet after every re-boot for about a day, then the same troubles come back. It may be quiet for several days, then, get several of the above events in the span of a couple of hours, then quiet for a few more days.
I have not replaced any hardware yet, but was thinking of replacing the CPU first. Other than the Power Supply, I have 2 16 port station cards and 2, 8 port trunk cards.
Any thoughts on troubleshooting going forward?
The Customer is keeping a log of dates and events.
They are within 5 miles, which is a plus.
I've checked with all my NEC buddies, but no solid leads yet.
Should I start with the CPU replacement?
Thanks,
Techroy
