ADVANCE INFORMATION  
Le79ETR2  
Subscriber Line Interface Circuit (SLIC)  
The Le79ETR2 SLIC device implements the basic telephone line interface functions for a POTS application, includ-  
ing ringing. In addition, a DC feed/AC termination circuit for electronic telephones is included on the circuit.
