For SLIC-S2, only external ringing is provided.
SLIC-E/-E2 allows balanced ringing up to 85 Vrms and can, therefore, be used in
systems with higher loop impedance.
The low-power SLIC-P is optimized for power-critical applications (such as intelligent
ISDN network termination). Internal ringing can be used up to 85 Vrms balanced or 50
Vrms unbalanced. For lowest power applications where external ringing is preferred,
three different battery voltages (
consumption of the application.
SLIC-E/-E2 and SLIC-P differ in supply voltage configuration and the ring voltages at Tip
and Ring
Both internal and external ringing are activated by switching the DuSLIC to ringing mode
by setting the CIDD/CIOP

External Ringing Support by DuSLIC
The following settings must be made:
•
•
•
•
The ring relay is controlled by the IO1 pin (see
capability of the IO1 output, no additional relay driver is necessary.
The relay is switched either synchronously or asynchronously as follows:
•
A ring generator delay T
programmed to consider the ring relay delay T
•
The ring relay is switched immediately with the ring command.

CIOP = Command/Indication Operation
Enable the use of an external ring signal generator by setting bit REXT-EN in register
BCR2 to 1.
A TTL compatible zero crossing signal must be applied to the RSYNC pin of the

Activate the ringing mode by setting the CIDD/CIOP bits M2, M1, M0 to 101.
Set the DuSLIC internal ring frequency to a value according a factor of approximately
0.75 of the external ring frequency.
