The High Voltage Subscriber Line Interface Circuit SLIC-P (PEB 4266) is a reliable interface between the
telephone line and the codec devices of the DuSLIC
Technologies´ well-proven Smart Power Technology SPT 170.
Due to the integrated triple battery switch, the PEB 4266 enables highly flexible solutions, e.g.
•
•
The PEB 4266 is designed for a voltage-feeding/current-sensing line interface concept and senses the transversal
and longitudinal line current.
To minimize system power dissipation, a power-down mode can be used; the PEB 4266 is switched off and the
line outputs go to a high-impedance mode. Off-hook supervision is provided by activating a simple line current
sensor with negligible power consumption.
The PEB 4266 is compatible with both 3.3 V and 5 V

When using an external ring generator, the three battery voltages allow further reduction of power dissipation
due to a still better adaptation of battery voltage to loop length.
