FUNCTION The keyboard input may be from either the standard 4 x 4 keyboard or an inexpensive single contact (form A) keyboard. Electronic input from a C can also be used. A valid key entry is defined as a single row being connected to a single column. A built-in inverter provides oscillation with an inexpensive 3.579545 MHz crystal or ceramic resonator. The T/P MUTE is a conventional CMOS N-channel open drain output. The output transistor is switched on during pulse and tone mode dialing sequence and flash break. Otherwise, it is switched off. Pulling mode pin to VSS places the dialer in tone mode. Pulling mode pin to VDD places the dialer in pulse mode (10 ppS). Leaving mode pin floating places the dialer in pulse mode (20 ppS). Hook switch input. HKS = 1: On-hook state. Chip in sleeping mode, no operation. HKS = 0: Off-hook state. Chip enabled for normal operation. The HKS pin is pulled to VDD by an internal resistor. N-channel open drain dialing pulse output (Figure 1). Flash key will cause DP to go active in both pulse mode and tone mode. In pulse mode, remains in low state at all times. In tone mode, outputs a dual or single tone. Detailed timing diagram for tone mode is shown in Figure 2(a, b).

Mixed Dialing
1. Definition of mixed dialing: In mixed dialing, a new sequence may be accepted only when the previous sequence has been dialed out completely. The following are examples of mixed dialing: Example 1: Normal dialing + (1st sequence) Example 2: Repertory dialing 1 (1st sequence) Example 3: Redialing + + Repertory dialing 1 (2nd sequence) Normal dialing (2nd sequence) Normal dialing (2nd sequence) + + + Repertory dialing 2 + ..... ... (3rd sequence) Repertory dialing 2 (3rd sequence) +...... .... + ...... ...
Repertory dialing 1 (3rd sequence)
(1st sequence)
2. There is no limitation on the number of digits and sequences in the mixed dialing. 3. The content of mixed dialing may be a combination of normal dialing, memory dialing, or one-key redialing. 4. If ON HOOK , OFF HOOK (or ON HOOK & HFI o ), RD is entered,
then the mixed dialing sequence described in the above examples will be dialed out only if the total number of digits does not exceed 32. If the total exceeds 32 digits, then redialing is inhibited.
