3. Facsimile Call Time Series
As shown in the following diagram, the facsimile call time series is divided into five phases.
Phase A : Call setting
Call setting can be manual/automatic.
Phase B : Pre-message procedure
Phase B is a pre-processing procedure and sequence for confirming the status of the terminal, transmission route, etc. and for
terminal control. It implements the terminal preparation status, determines and displays terminal constants, confirms
synchronization status, etc. and prepares for transmission of facsimile messages.
Phase C : Message transmission
Phase C is the procedure for transmitting facsimile messages.
Phase D : Post message procedure
Phase D is the procedure for confirming that the message is completed and received. For continuous transmission, phase B
or phase C are repeated for transmission.
Phase E : Call retrieval
Phase E is the procedure for call retrieval, that is for circuit disconnection.
4. Concerning Transmission Time
Transmission Time
= Control Time
+ Image Transmission Time
+ Hold Time
Transmission time consists of the following.
Control time:
This is time at the start of transmission when the functions at the sending and receiving sides are confirmed, the
transmission mode is established, and transmission and reception are synchronized.
Image transmission time:
This is the time required for the 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.
