L3924A - (L3914A - L3934A) SPEECH AND 14 MEMORY DIALER

Download the L3924A datasheet PDF. This datasheet also covers the L3914A variant, as both devices belong to the same (l3914a - l3934a) speech and 14 memory dialer family and are provided as variant models within a single manufacturer datasheet.

Description

The device consists of the speech and the dialer.

It provides the DC line interface circuit that terminates the telephone line, analog amplifier for speech transmission and necessary signals for either DTMF or loop disconnect (pulse) dialing.

Features

  • provided by the PABX or central office. The PAUSE key stores a timed pause in the number sequence. Redial is then delayed until an outside line can be accessed or some other activity occurs before normal signaling resumes. A LND key input automatically redials the last number dialed. The HOLD key allows the user to suspend the conversation and resume the call on either the same phone by pressing the HOLD key again or resume the conversation at a parallel phone.
