A PLD (Programable Logic device) is equipped on KX-NS5180, and this device has several interfacing functions as below.

Transmits 10pps/20pps dial pulse by a open/close action between Tip and Ring with Photo MOS relay which is controlled by DSP
(IC101).
The make width, break width and inter digit width for 10pps/20pps can be set respectively.

When making DP[0-5] pin of DSP (IC101) becomes Low level, and RL101A-F turns ON. When breaking,
