Overview
SC91214/91215 SERIES T/P SWITCHABLE DIALER WITH REDIAL HANDFREE FUNCTION DESCRIPTION The SC91214/15 Series is a single-chip, silicon gate, CMOS integrated circuit with an on-chip oscillator for a 3.
58MHZ crystal or ceramic resonator.
It provides a dialing pulse (DP) or dual tone multifrequency (DTMF) dialing.
A standard 4 X4 matrix keyboard can be used to support either DP or DTMF modes.
FEATURES * One touch redial operation * Tone/Pulse switchable * 32 digit capacity for redialing * Automatic mixed redialing (last number redial) of pulse to DTMF with multiple automatic access pauses * PABX auto-pause is 2.
2 seconds ORDERING INFORMATION * DTMF Timing: Manual dialing: minimum duration for bursts and pauses Redialing: calibrated timing * Hands-Free control function * Wide operating voltage range: 2V to 5.
