Chapter 3 – Fax Class 2 Commands

T.30 Session Subparameters

Several commands and responses reference T.30 session negotiated parameters. These are described by a set of common subparameters, which are described in Table 3.5. Optional parameter values are marked with an asterisk (*).Unspecified parameter values are reserved for future use.

The +FCC [+FDCC], +FIS [+FDIS], and +FCS [+FDCS] compound parameters, described in Parameter Commands sections, use these session subparameters. On writes, unspecified subparameters are unchanged.

The +FIS: [+FDIS:], +FCS: [+FDCS:], and +FTC: [+FDTC:] session report responses, described in T.30 Phase B Negotiation Responses section, also use these subparameters.

For test response, ranges of values are reported for each subparameter, enclosed in parentheses characters. For example, a modem response to +FCC=? [+FDCC=?] could report:

<CRLF>(0-1),(0-3),(0-4),(0-2),(0),(0),(0),(0-7),(0)<CRLF>

Example: +FIS=0,3,0,2,0,0,0,1,0 is interpreted as follows:

Value	Label	Description
0	VR	98 dpi vertical resolution

3	BR	9600 bit/s

0	WD	1728 pixels

2	LN	unlimited length

0	DF	1-D modified Huffman coding

0	EC	no ECM

0	BF	no BFT

1	ST	5 ms scan time

0	JP	no JPEG
