              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 FOLLOWED 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 OCCASION) 
 
TIMING FOR THE CSPI IS PROVIDED BY A FREE RUNNING 4.9152 MHZ CLOCK AND A 
FREQUENCY DIVIDER CIRCUIT. 
 
THE TRAILING EDGE OF THE 8 US PULSE CLOCKS THE DATA INTO A REGISTER AND 
TRIGGERS A 150 NS,ONE SHOT MULTIVIBRATOR 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 TIMES 
BETWEEN RESET SIGNALS.

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