3.2.1Circuit control signals

The following circuit control signals are used in the binary and tonal procedures.

•Circuit control signals

CED	Called station identification
	Indicates that the sender is a FAX machine in the automatic called
	mode. (*1)

CNG	Calling tone
	Indicates that the sender is a FAX machine in the automatic calling
	mode. (*1)

*1: This signal can be sent manually.
