SATURN IIE EPABX General Description 4.05 Control Logic. The control logic performs the follow- ing functions: a. Power Failure Interrupt (PFI). Generates a nonmaska- ble interrupt to the CIOP when input power drops to the brown-out level (95 to 97.5 Vat) and returns to nor- mal when power becomes higher than 100 Vat. b. Ring synchronization. Generates the timing signals for operating and releasing ringing relays. c. Ringing/message-waiting control. Selects either ring output or...
