Phase C Data Format Parameters

Chapter 3 – Fax Class 2 Commands

Data Bit Order: +FBO and +FBOR

Class 2.0/2.1 +FBO

Write syntax: +FBO=<value>


Valid values:		0, 1
Default value:		0
This parameter controls the mapping between PSTN facsimile data and the host-
modem link. There are two choices:
+FBO=0	Direct bit order for both Phase C data. The first bit transferred of each
	byte on the host-modem link is the first bit transferred on the PSTN data
	carrier.
+FBO=1	Reversed bit order for Phase C data. The last bit transferred of each byte
	is the first bit transferred on the PSTN data carrier.

The effect of this parameter is illustrated for the EOL pattern in the Phase C Data Format Parameters section in this chapter.

Class 2	+FBOR
	Write syntax:	+FBOR =<value>
	Valid values:	0, 1
	Default value:	0
	This parameter controls the mapping between PSTN facsimile data and the host-
	modem link. There are two choices:
	+FBOR=0	Direct bit order for both Phase C data. The first bit transferred of each
		byte on the host-modem link is the first bit transferred on the PSTN
		data carrier. Applies to FAX sending for all Multi-Tech modems.
	+FBOR=1	Reversed bit order for Phase C data. The last bit transferred of each
		byte is the first bit transferred on the PSTN data carrier. Applies to
		FAX sending for all Multi-Tech modems.

The effect of this parameter is illustrated for the EOL pattern in the Phase C Data Format Parameters section in this chapter.

Phase C Received EOL Alignment: +FEA and +FREL

Class 2.0/2.1 +FEA

	Write syntax:	+FEA=<value>
	Valid values:	0, 1
	Default value:	0
	+FEA=0	EOL patterns are bit-aligned as received.
	+FEA=1	The last received bits of EOL patterns are byte-aligned by the
		modem, with necessary zero fill bits inserted. There are two 2-byte
		binary EOL patterns, in which xxxx represents previous data bits, zero
		bits, or other leading data:
		+FBO=0:		0000xxxx 10000000
		+FBO=1:		xxxx0000 00000001
Class 2	+FREL
	Write syntax:	+FREL=<value>
	Valid values:	0, 1
	Default value:	0
	+FREL=0	EOL patterns are bit-aligned as received.
	+FREL=1	The last received bits of EOL patterns are byte-aligned by the
		modem, with necessary zero fill bits inserted. There are two 2-byte
		binary EOL patterns, in which xxxx represents previous data bits, zero
		bits, or other leading data:

			+FBOR=1: 0000xxxx 10000000
			+FBOR=1: xxxx0000 00000001
