Non-volatile Static RAM
15.5 Any time the user enables a function such as Call Forwarding the changed data
(extension number, type of forwarding) must be saved in a non-volatile memory so
that it is not lost on power down or system failure. The Static RAM acts as a buffer for
this sort of data. As the data accumulates, finally filling up the buffer, it 'is then
transferred to disk. This reduces disk running time, increasing the disk drive's life
span. During power-off periods, the static RAM is powered from a large capacitor,
providing 72-hour holdover time.
