Features

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

22-Memory Tone/Pulse Dialer

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.
