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.

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.

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.
