Used for FAX class 2 only 
This command requests the ME to transmit a Phase C page. When the ME is ready to accept Phase 
C data, it issues the negotiation responses and the CONNECT result code to the application. 
In Phase B, this command releases the ME to proceed with negotiation, and releases the DCS 
message to the remote station. 
In Phase C, this command resumes transmission after the end of a data stream transmitted before.
