Telephone Speech Network with Dialer Interface

Description

The GL6965 is a bipolar integrated circuit for

use in electronic telephones.

The GL6965 has low operating voltage, it pro-

vides an excellent branch performance.

It has line voltage increasing circuit by the

exter-nal terminal. Transmitting and receiving

gains automatically vary according to the line

current.
