tDETDT : Time to Detect

When Time to Detect is the specified value of tDETDT or more, the DTMF signal is normally received.

tREJDT : Time to Reject

When Time to Reject is the specified value of tREJDT or less,

the input signal is ignored and the SPB and DTMF receive data are not output.

tPOSDT : Interdigit Pause

When there is no input signal for the period of tPOSDT or more, the DTMF receive data

and SPB are reset.

Even if the receive data is changed, when Interdigit Pause Time is the value of tPOSDT

or less (including the change without Drop Out), SPB remains at "0"

and the DTMF receive data may maintain its initial value.

tBRKDT1 : Acceptable Drop Out Time 1

Acceptable Drop Out Time 1 is applied between when the input signal comes

and when SPB becomes "0".

Even if there is no input signal for the period of tBRKDT1 or less,

the SPB and DTMF receive data are normally output.

tBRKDT2 : Acceptable Drop Out Time 2

Acceptable Drop Out Time 2 is applied when SPB is "0" (when receive data is output).

Even if there is no input signal during signal reception for the period of tBRKDT2 or less,

SPB and DTMF receive data are not reset.

tCYCDT : Signal Repetition Time

Signal Repetition Time should be the specified value

of tCYCDT or more so that a signal is normally received.

tDELDT : Detect Delay Time

The DTMF receive data is output with a delay of the specified value

of tDELDT after the input signal appears.

tHOLDT : Detect Hold Time

The SPB and DTMF receive data outputs stop with a delay of the specified value

of tHOLDT after the input signal disappears.

tSP : SPB Delay Time

The SPB data is output with a delay of the specified value

of tSP after the DTMF receive data is output.

The DTMF receive data should be latched after detecting the fall of SPB.
