Programming (cont’d)
ASYD - System Data 1, Index 14 determines the algorithm used to calculate the last two digits of
every AUTHORIZATION CODE. (Only decimal numbers may be used in this index, therefore,
hexadecimal values A to F may not be assigned).
System Data 1, Index 14 = X & Y, where X and Y represent any arbitrarily chosen decimal digit 1- 9,
and where Y is used to determine the first digit, and X is used to determine the second digit in the
Checksum method. The following data, 37H, has been used for the example calculation:
Note: If only one digit is to be added via the Checksum method, then System Data 1, Index 13 data will be 00H
and Index 14, digit X (Bits 4 - 7) = 0.
Example Calculation:
In AATC, 26428 has been assigned. In System Data 1, Index 12, Bits 0 and 3 were chosen; 26428
2 + 2 = 4.
The decimal value of Bits 0 - 3 of Index 14 = 7.
4 + N =7. N = 3.
7 is obtained as any whole number greater than 4 that ends with a 7, the decimal value as determined in
System Data 1, Index 14, Bits 0 to 3. In AATC, 26428 has been assigned. In System Data 1, Index 13,
Bits 4 and 1 were chosen; 26428
8 + 6 = 14.
The decimal value of Index 14, Bits 4 - 7, is 3.
14 + N = 23. N = 9.
23 is obtained as any whole number greater than 14 that ends with a 3, the decimal value determined in
System Data 1, Index 14, Bits 4 - 7. The AUTHORIZATION CODE will be 26428-39.
Note: Digits 39, determined by the Checksum method, will be unique to the AUTHORIZATION CODE 26428.
26428 will not be followed by any digits other than 39.
ASYD - System Data 1, Index 43, Bit 2, is service set tone sent after AUTHORIZATION CODE
ASPA access code? 0/1: No/Yes. Assign data “1”. System Data 1, Index 93, Bit 6. Are the AMND
tables Separate or Common for tenants in the system? 0/1: Separate/Common. Assign data “0” for
separate tables.
System Data 2, Index 3, Bit 4: Is Account Code used with AUTHORIZATION CODE? 0/1: No/Yes.
System Data 2, Index 3, Bit 5: Type of code: 0/1 AUTHORIZATION CODE/ Forced Account Code;
assign data “0”.
STEP 2: ANPD
- Reserve a number level for feature access. Assign for Normal (N), Hooking (H), and Busy
(B) (if applicable to any feature in this level). Assign NND in accordance with a predetermined
numbering plan.
STEP 3: ASPA - For SRV = SSC (Service Code) SID = 42, assign the access code. For the NND parameter, no
assignment is required when AUTHORIZATION CODE [A-20] operates by itself. When Account
Code [A-18] operates with AUTHORIZATION CODE - TIE LINE INCOMING ROUTES, assign for
SRV = SSC (Service Code), SID = 42. The NND value will include the number of digits in the
AUTHORIZATION CODE access code, and Account Code.
