Lots of static that was on a few lines is now everywhere. Swapped a few digital cards, no change. I have a 2nd unused cabinet, so I swapped power units, no change.
Layout order is PSU, an unused but powered SSC card (no fiber link to 2nd cab), DTI/PRI card, 5 dig cards, 1 analog card, and an MM module.
When I use an external phone to ring into the system, there is static during the ringtone. The same type we hear internally when dialing extensions (or just by picking up a handset).
Electrical engineer (my boss, an ex-T.I. guy) checked system ground and connections but found nothing out of the ordinary.
