TELTONE M-907 TONE DETECTOR AND ROTARY DIAL PULSE COUNTER
FEATURES
--------
- A complete LSI digital TOUCH-TONE® detector and rotary dial counter
contained in an assembly requiring less than 4.52 * 3.02 * 0.6 inches
(115 * 76.25 * 15.24 millimeters).
- Meets or exceeds telephone ccentral office requirements for DTMF
reconition and voice talk- off protection.
- Fully time- guarded rotary dial pulse counting.
- Decodes all 16 DTMF digits and counts rotary dial digits.
- Crystal controlled LSI digital circuitry assures maximum frequency
detection accuracy and stability.
- Provision for tone detection sensitity adjustment.
- Selectable output formats of binary, 2 of 8 (2 of 7), and 1 of 12.
- Selectable button- up or button- down operation.
- Seperate outputs indicate dial pulse or early tone presence.
- Low power consumption : Typically 60 ma at 12 VDC.
GENERAL DESCRIPTION
-------------------
The TELTONE® M-907 Receiver Assembly is designed for applicattion where a
high performace CENTRAL OFFICE GRADE TOUCH-TONE (DTMF. Dual- Tone Multi-
Frequency) and/or a rotary dial pulse counter is required. The receiver's
compact size and low heat emmission make it well suited for high density
packaging.
The receiver consists of a bridging buffer amplifier, dial tone filters,
both high and low pass filters, dual limiters, and a crystal controlled
digital frequency detector capable of detecting all 16 DTMF digits.
A dial pulse counter detects rotary dial digits. Figure 1 displays the
the functional block diagram. The unit can be programed to accept DTMF
signals only, rotary dial pulses only, or to provide mixed DTMF and
rotary dial operation with the further capability of cross- inhibiting
as determined by the first digit received.
Data outputs will interface with MOS or CMOS and will also drive one
low power Schottky TTL gate or low-power transistor. The externally
selectable outputs are available in 2 of 8 or 2 of 7 (as described in
Table 1), binary, or 1 of 12 formats. Figure 2 displays the outputs
available. A number of options, discussed in the Application Notes,
are available to answer a wide variety of requirements, such as strobing
by extemal equiqment.
APPLICATION NOTES
-----------------
Applications for the TELTONE M-907 Assembly include PABX and central office
receivers, data transmission, tone and/or rotary dial controlled dictation
links, radio telephone systems, and other applications where a telephone
dialing mechanism or an analogous device will be used to convey information.
The TELTONE M-907 Receiver Module has been designed to provide maximum
flexiblity in a variety of customized applications by selection from among
the following features. Figure 3 displays a typical application using most
of the listed features.
BD (Button Down) Output, pin 12. The BD option provides an early tone
presence signal that starts 16ms after a valid tone pair is detected
and ends -25ms after the tone pair ends. This is displayes on the
DTMF digit timing chart, figure 5.
RD (Rotary Dial) Output, pin 4. The RD option provides an early dial
pulse presence signal that starts at the leading edge of the first
break pulse and ends 100ms after the trailing edge of the last pulse.
This is displayed on the rotary dial timing chart, figure 6.
__ __
LC (Loop Current Not) Input, pin 29. The LC input is the rotary dial
pulse input lead. A logic 0 (-V) represens and off- hook condition
or make period. A logic 1 (+V) represents an on-hook condition or
break period. For DTMF operation only. LC can be connected to (-V);
then the receiver is enabled as long as the CLEAR input is at logic 0.
OFF- Output, pin 5. The off-hook output goes high (logic 1)
HOOK 100ms after the LC input goes low. The output goes low (logic 0)
300ms after the LC input goes high.
DTI (Dual Tone Inhibit) Input, pin 2,
and
RDI (Rotary Dial Inhibit) Input, pin 1. For mixed DTMF and rotary dial
operation, connect DTI and RDI to (-V). For rotary dial operation
only, connect DTI to (+V). For DTMF operation only, connect RDI to
(+V). For mode locking on the first digit detected, connect both DTI
and RDI to GUDTA. The mode lock will be held until an on-hook
condition occurs or a logic 1 is applied to the CLEAR input.
HOLD Input, pin 28. For applications where the output data has to remain
to unchanged for an extended time period, wheter or not additional
digits have been received, switch HOLD to logic 1 after GUDTA occurs.
CLEAR Input, pin 3. A logic 1 applied to CLEAR input will instantaneously
reset the Receiver's DTMF outputs will be forced to the condition
shown in the D state columns (rightmost) as conditioned by the logic
levels on FCA and FCB, see figure 2.
FCA (Format Control A) Input, pin 26.
and
FCB (Format Control B) Input, pin 27. The Format Control inputs determine
the DATA output format. Figure 2 displays the varous outputs available,
as determined by the logic levels at FCA and FCB. FCA and FCB can also
be used as a data strobe. By holding both inputs at logic 1, all data
outputs will remain at logic 1 until FCA and/or FCB are changed to
logic 0.
GUDTA (Good Data) Output, pin 23. After 35 milliseconds of valid DTMF
detection, the DATA outputs change to the programmed output.
GUDTA occurs within ten microseconds after DATA change and persists 25
milliseconds after the end of DTMF detection, see figure 6. For DATA
to be read during DTMF signal presence, strobe the leading edge of
GUDTA (button down). For DATA to be read after DTMF signal presence,
strobe trailing edge of GUDTA (button up).
SEN (DTMF Sensitivity Adjustment) Controls, pins 6 and
ADJ 7. For applications where extended DTMF detection sensitivity is
required, connect a resistive shunt across pins 6 and 7. A 50K ohm
shunt will increase the sensitivity by approximately 3.5dB; a short
will increase the sensitivity by approximately 7 dB.
DATA 0 (Data Outputs) Output, pins 14 thru 25. The data output
thru states of all 16 digits for any possible condition
DATA of FCA and FCB are shown in figure 2. Logic state 1 and logic state
0 are defined in the Performance Characteristics under Output
Specifications.

Refer to figure 7 for maximum dimensions. Figure 8 displays the
required PC component side layout and the relation to the assembly.
