NSF, NSC, NSS:
NSF, NSC, NSS are nonstandard unit frames. The first three bytes of the FIF are specified by T.30.
The subsequent digits are individually determined by the manufacturers. The first byte refers to the
country code. The second byte is a spare; it is 00 (hex) presently. The third byte is the manufacturer
code.

NSF 20 00 00 45 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
The third byte is the manufactures code
The second byte is spare; currently set at 00H
The first byte indicates the country code
Indicates the NSF code
CSI, CIG, TSI:
CSI, CIG, TSI is composed of a maximum 20-digit number comprising the country code, area code,
and subscriber’s telephone number. In the printed results, printing starts from the least significant digit
of the telephone number. The following code table lists the codes used to make the 20-digit number
and their value. Below the code table is a CSI example.
Code Value Code Value Code Value Code Value
20 Space 32 2 35 5 38 8
30 0 33 3 36 6 39 9
31 1 34 4 37 7 2B +
An example telephone number of 123-456-7890 is represented as:
TxFrame RxFrame D A T A

DIS, DTC, DCS:
DIS, DTC, DCS frames define the standard CCITT capabilities of the two units such as transmit and
receive speeds, coding methods, printer speed, etc.

The bits are in the following order:
( 8 7 6 5 4 3 2 1) (16 15 14 13 12 11 10 9) (24 23 22 21 20 19 18 17)
(32 31 30 29 28 27 26 25) (40 39 38 37 36 35 34 33) (48 47 46 45 44 43 42 41)
(56 55 54 53 52 51 50 49) (64 63 62 61 60 59 58 57)
Table for hexadecimal digit to binary number:
Hex Binary Hex Binary Hex Binary Hex Binary
0 0000 4 0100 8 1000 C 1100
1 0001 5 0101 9 1001 D 1101
2 0010 6 0110 A 1010 E 1110
3 0011 7 0111 B 1011 F 1111
So in the above list the first "EF" is "11101111"(bit order 8 7 6 5 4 3 2 1)
