General Description
The HT9320 series tone/pulse dialers are
CMOS LSI for telecommunication systems.
They are designed to meet various dialing spec-
ifications through resistor option matrix.
The HT9320 series are offered in six different
versions. The different functions of the six ver-
sions are listed in the selection table. The
HT9320A, HT9320H versions provide the
on-hook store function; the HT9320B version
provides the LCD interface function; the
HT9320K version provides the keytone func-
tion; the HT9320L version provides both the
LCD interface function and IDD lock function.
The six versions also supply the hold-line and
hand-free functions, which are suitable for feature
phone applications.
HT9320 series provide SA, Redial and 20
one-touch/two-touch memory dialing. If the
keyboard includes M1~M20 keys it can be used
as one-touch memory dialing. Otherwise, it
works as two-touch (PAGE®M1~M10) or
three-touch(A®PAGE®0~9) memory dialing
for speed dialing in either pulse or tone mode.
