Service Class 2 DCE Responses
The DCE sends information responses to the DTE as a facsimile session proceeds. They
indicate the state of the facsimile session and convey needed information. These
messages are solicited messages generated in execution of DTE action commands
described elsewhere in this appendix.
The DCE precedes and follows the information responses with <CR><LF>. The DCE
provides the on-line status of several session parameters when they are available during
T.30 handshaking. These include the remote ID string and the DIS/DCS parameters.
These responses report the T.30 session parameter frames. The subparameters are
described in Table A-23.
+FCON - Facsimile Connection Response
+FCON indicates connection with a fax machine. It is released by detection of HDLC
flags in the first received frame. +FCON is generated in response to an Originate or
Answer command.
+FDCS: - Report Current Session Capabilities
Syntax +FDCS:VR,BR,WD,LN,DF,EC,BF,ST
+FDCS:<string> reports the negotiated parameters. Phase C data will be formatted as
described by the subparameters. This message may be generated in execution of +FDT or
+FDR commands before the CONNECT result code if new DCS frames are generated or
received. (See Table A-23.)
+FDIS: - Report Remote Station Capabilities
Syntax +FDIS:VR,BR,WD,LN,DF,EC,BF,ST
+FDIS:<string> reports remote facsimile station capabilities and intentions. The
parameters are provided in ASCII notation. (See Table A-23.)
This message is generated in execution of Originate, Answer, +FDT, or +FD commands.
+FCFR - Indicate Confirmation to Receive
Syntax +FCFR
The DCE sends a +FCFR response to the DTE upon reception of an acceptable TCF
training burst and a valid DCS signal from the remote machine. This indicates that the
DCE will receive Phase C data after the remote station receives the local DCE's CFR
message. The +FCFR message is generated in execution of a +FDR command.
