Operating Modes
Unbalanced (external) Ringing
The sine wave for ringing is generated by an external ring generator. To coordinate with
the SLICOFI following settings must be done:
1. IO1 set as an output
2. SCR5-2 (REXTEN) = 1
3. RING-(CIDD7) = 1 (PDown: Ring Pause)
4. TIM-(CIDD5) = 1 (Ringing: Ring Burst On)
Pin REXT: a positive puls according to zerocrossing of the ringer voltage
RINGING:
5. signal for relays on IO1
6. HV-SLIC in PDen Mode
V
7. SLICOFI in PDown Mode, Offhook-detection via
LINE1,2
RING PAUSE:
8. TIM-(CIDD5) = 0 (PDown: Ring Pause), Offhook-detection via IT (in the same way as
balanced ringing)
