lc7367j, 7367jm no.3095C7/12 (5) timing of flash (6) mix dial and redial (key entry available after redial) by p/t input (slide sw, stc.) ? even when the tone mode (p/t sw : tone) is entered at the off-hook state, the output-pulse mode can be entered (p/t sw : pulse). ? the output mode provided when redialing is the one provided when dialed previously (regardless of the p/t sw position when the rd key is pushed). ? the mode after completion of redialing is set again by the p/t sw position provided when redialing is completed. since the dp, mute1, mute2, mode-out outputs are of the nch open drain type, the output transistor off-state (h-impedance) provides h-level. likewise, since the dtmf output is of the emitter follower type, the output transistor off-state (h-impedance) provides l-level.
