Repertory Dialer

The MK53761 is a Silicon Gate CMOS IC that pro- vides necessary signals for eitherDTMF or loop dis- connect (pulse) dialing. The MK53761 buffersup to 18 digits intomemory that CAN be later redialedwith a single key input. Up to nine repertory numbers may bestored. Users CAN store all 12 signaling keys and access several unique functionswith single key entries. These functions include : LastNumber Di- aled (LND), Softswitch, and Flash Figure 2 shows the keypad configuration. A LND key input automatically redials the last num- ber dialed. The PROG key provides an easyway to program a number into any memory location (1-9) whether on-hook on off-hook.TheMEM key allows easy redialing of the number stored in memory lo- cations (1-9). The Flash key simulates a 560 ms hook Flash to transfer calls or to activate other special features provided by the PABX or a central office. By STMicroelectronics
