It provides a dialing pulse (DP) or dual tone multi-frequency (DTMF) dialing. A standard 4 x 4 matrix keyboard can be used to support either DP or DTMF modes. Up to 32 digits can be saved in the on-chip RAM for redialing. In the DTMF mode, a short minimum tone duration and minimum intertone pause allows rapid dialing. Maximum tone duration depends on the key depression time during manual dialing.

The dialing rate or make/break ratio is decided at the first key entry by checking the MODE IN status and will not be altered. The MODE IN status can only switch On Hook means that the phone is on the hook. D1 represents for the first digit dialed in a string of digits. Dn ( Dk ) represents for the last digit dialed in a string of digits. Dn+1 represents for the beginning of a new string of digits. Dn+m represents for the last digit in a new string of digits.
