I have a DSX-80 that is equipped as follows;
8 CO trunks
16 Digital Ports
8 Analog Ports
4 Port Intramail

System has been in service for approximately two years and works like a charm. I have (2) 22 Btn Display sets and (1) Analog set in an adjacent building (122' 25 pr UGC). I was called to the site today and when I arrived at the remote sets, both of the displays said INITIALIZE and were in OOS condition.

I have Edco lightning protection on the UGC and is bonded to cable sheath on one end with verified earth ground. The protectors were not blown and there was no physical trace damage inside the cabinet or cards. I performed a complete power down and reboot to see if the issue was cleared. When the system came back online, the two 22 btn kts were in the same condition.

I have installed many, many of the DSX series systems and prior to today, had never saw this on a display. Have any of you guys ran into this issue? If so, what did you do to resolve the problem. I appreciate your help in advance.......
