              NOTES

1. WHEN THE AL CARD IS NOT APPLIED,THE
SPECIFIC TONE IS APPLIED.

2. DTMF-A=700+1630 HZ AT -7 DBMO

3. DTMF-B=770+1630 HZ AT -7 DBMO

4. DTMF-C=850+1630 HZ AT -7 DBMO

5. DTMF-D=940+1630 HZ AT -7 DBMO

6. ABC PROMPT TONE IS 100 MS OF DC FOLL
OWED BY 60 MS OF 941+1477 HZ FOLLOWED BY
350+440 HZ STARTING AT -7 DBMO AND
EXPONENTIALLY DECAYING WITH A 200 MS
TIME CONSTANT FOR THE REMAINDER OF
1 SECOND.

7. A BINARY CODE(7E HEX) REPRESENTING
   QUITE TONE(NO TONE) IS STORED AT
   OAM ADDRESS O HEX.

8. SIGNAL LEVEL PER SINGLE FREQUENCY.

9. SIGNAL LEVEL OF COMBINED FREQUENCIES
.
MASTER CLOCK=2.048 MHZ
SLAVE CLOCK =666 2/3 HZ

ODD PARITY(THOUGH MAY BE EVEN ON OCCASI
ON)

TIMING FOR THE CSPI IS PROVIDED BY A FR
EE RUNNING 4.9152 MHZ CLOCK AND A FREQUE
NCY DIVIDER CIRCUIT.

THE TRAILING EDGE OF THE 8 US PULSE
CLOCKS THE DATA INTO A REGISTER AND
TRIGGERS A 150 NS,ONE SHOT MULTIVIBRATO
R
THE CUT THROUGH SIGNALS INDICATE THE
BEGINNING OF 6.5 OR 13.5 SECOND MSGS.

THE ADDRESS COUNTER IS AN 8 BIT SYNC
COUNTER CLOCKED BY THE 2.048 MHZ
CLOCK AND RESET BY THE 666 2/3 HZ CLOCK
.
THE COUNTER CYCLES FROM 0 TO 255,12 TIM
ES BETWEEN RESET SIGNALS.



OK-THIS TIS THE TECH DATA THAT EVERYON
E
   NEEDS TO DO ??? (HEE-HEE)
A LOT OF THIS INFO HAS NEVER BEEN RELEA
SED BEFORE,SO A LOT OF POSSIBILITIES ARE
NOW POSSIBLE!LET ME KNOW OF YOUR EXPERI
MENTS,AND HAVE PHUN-N-N-N!!!!!!!!!!
