Command Reference Manual
1199 5-19
The +FPHCTO command determines how long the DCE will wait for a command after reaching the end of data when
transmitting in Phase C. When this time-out is reached, the DCE assumes there are no more pages and no documents to
send. It then sends the T.30 EOP response to the remote device.
5.5.9 +FAXERR - T.30 Session Error Report
Read syntax: +FAXERR= <table value>, read only
Valid values: 0 - 255, see Table 5-5 for meaning
This read-only parameter indicates the cause of the hangup. Table 5-5 shows the valid values for this parameter as well as
the meaning of the each value. +FAXERR is set by the DCE at the conclusion of a fax session. The DCE resets +FAXERR to
0 at the beginning of Phase A off-hook time.
5.5.10 +FBOR - Data Bit Order
Write syntax: +FBOR=<value>
Valid values: 0, 1, 2, or 3
Default value: 0
This parameter controls the mapping between PSTN facsimile data and the DTE-DCE link. There are two choices:
Direct: The first bit transferred to each byte on the DTE-DCE link is the first bit transferred on the PSTN data carrier.
Reversed: The last bit transferred of each byte on the DTE-DCE link is the first bit transferred on the PSTN data carrier.
There are two data types to control:
This command controls Phase C data (T.4 encoded data) transferred during execution of +FDT or +FDR commands.
The following two codes are supported:
+FBOR=0 or 2 Selects direct bit order for Phase C data.
+FBOR=1 or 3 Selects reversed bit order for Phase C data.
This parameter does not affect the bit order of control characters generated by the DCE.
5.5.11 +FAA - Answer Parameter
Write syntax: +FAA=<value>
Valid values: 0 or 1
Default value: 0
+FAA=0 Constrains the DCE to answer as set by +FCLASS.
+FAA=1 Indicates that the DCE can answer and automatically determine whether to answer as a Class 2
facsimile DCE or as a data modem. If the DCE automatically switches, it modifies FCLASS
appropriately.
Fax adaptive answer operates only when +FCLASS=0.
Class 2 adaptive answer is implemented as follows:
First, a data mode handshake is attempted. If the DCE has been configured for automode detection (using the +MS
command), the DCE may try several protocols before terminating attempts to make a data mode connection. This can take as
long as 6-8 seconds.
If the data mode connection attempt fails, a facsimile Class 2 connection is assumed. When a connection is made as a result
of the adaptive answer, the DCE issues the DATA or FAX result code before the CONNECT or +FCON message to inform the
DTE of the connection type. After making a Class 2 connection, the DCE stays on-line rather than going into the command
mode as with a Class 1 connection.
