GENERAL DESCRIPTION
The TEA1069 and TEA1069A contain all the functions
needed to build a highly featured, high-performance fully
electronic telephone set.
The device incorporates a speech/transmission part, a
dialler part and a ringer part. By offering a wide range of
possible adaptations for each part, the TEA1069 and
TEA1069A application can be easily adapted to meet
different requirements.
The TEA1069A offers some different timings and diode
options compared to the TEA1069.
Where pin numbers are mentioned in this data sheet we
refer to the TEA1069N, unless otherwise indicated.
Speech part
The speech/transmission part performs all speech and line
interface functions required in electronic sets. It operates
at line voltages down to 1.6 V DC to facilitate the use of
more telephones connected in parallel.
Dialler part
The dialler part offers a 32-digit Last Number Redial (LNR)
and 13 memories. Hands-free control is included allowing
the TEA1069 and TEA1069A to be used not only in basic
telephones, but also in feature phones offering hands-free
dialling via the TEA1083 call-progress monitor IC and/or
full hands-free operation via the TEA1093 hands-free IC.
The hold function allows the user to suspend the
conversation and resume the call either on the same
phone or on a parallel phone. Additionally through the
music-on-hold function a melody is transmitted while the
set is put on hold. The keytones provide in a buzzer an
audible feedback of a valid key pressed.

Ringer part
The ringer part offers a discriminator input which enables the tone output as soon as a valid ring frequency is detected.
It offers a melody based on 3 tones with programmable melody and volume via keyboard.
