Phase A : Call setting
Call setting can be manual/automatic.
Phase B : Pre-message procedure
Phase B is a pre-processing procedure and a sequence for confirming status of terminal, transmission route, etc. and for ter-
minal control. It implements terminal preparation status, determines and displays terminal constants, confirms synchroniza-
tion status, etc. and prepares for transmission of facsimile messages.
Phase C : Message transmission
Phase C is the procedure for transmission of facsimile messages.
Phase D : Post message procedure
Phase D is the procedure for confirming that the message is completed and received. In the case of continuous transmission,
return is made repeatedly to phase B or phase C for transmission.
Phase E : Call retrieval
Phase E is the procedure for call retrieval, that is, for circuit disconnection.
4) Concerning Transmission of Time
I Transmission Time I= I Control Time ]+ I Image Transmission Time I + I H°ld Time I
Transmission time consists of the following.
Control time : This is time at the start of transmission when functions at the sending and receiving sides are confirmed,
transmission mode is established, and transmission and reception are synchronized.
Image transmission time:
This is the time required for transmission of document contents (image data). In general, this time is recorded
in the catalog, etc.
Hold time: This is the time required after the document contents have been sent to confirm that the document was in fact
sent, and to check for telephone reservations and/or the existence of continuous transmission.
