Description:     update on campus phones

Date: (YYYY-MM-DD)     2013-04-15

Start Time:              

End Time:		

Impact:           informational

Full telephone service was restored at approximately
9:30am this morning.

The issues were caused my failures of multiple
rectifiers, which started last Friday morning,
after several power interruptions the previous
day, which placed the campus PBX on battery
backup multiple times.

Out of a total of 5 rectifiers, 1 was replaced
Friday, and 2 more this morning.  The system
can operate with 4 rectifiers.

While the power events of last week were
unusual, the failure of multiple rectifiers
is not normal.  Testing and investigation
continues, multiple options will be explored
to ensure the PBX power supply meets requirements.
