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 actually sent, and to check for telephone reservations and/or the existence of
continuous transmission.
