Mailbox Communication
Types of Mailbox
This function is used to communicate between Fax machines compatible with a mailbox function
(ITU-T compatible). The owners of these Fax machines can input or retrieve the data of originals
in the mailbox.
There are 3 types of mailbox; confidential mailbox, bulletin board mailbox and multi-address
relay mailbox.
y Confidential mailbox:
Once the data of an original is retrieved from this box, this data will be deleted. If a new data
is input in this box under the same box number where another data exists, the new data will
be added to the existing data.
y Bulletin board mailbox:
Even if the data of an original is retrieved from this box, this data will not be deleted. If a new
data is input in this box under the same box number where another data exists, the new data
will overwrite the existing data.
y Multi-address relay mailbox:
A Fax machine with mailbox function transmits a Fax specifying a certain mailbox as a relay
mailbox, and then the relay station forwards the Fax to the destination previously registered
in the relay mailbox. In this case, the Fax machine of the original sender is called a relay
originator, the Fax machine which forwards the Fax is called a relay station and the Fax
machine which receives the Fax at the last stage is called a relay destination. A relay station
can send a report (relay destination transmission report) to a specified Fax machine involved
in the multi-address relay transmission after completing the transmission.A relay station can
also print out the Fax from a relay originator always or only when the relay transmission has
failed.
<Example of multi-address relay mailbox>
If you want to transmit the same original to several offices in New York from Los Angeles office,
you can reduce the communication cost utilizing a multi-address relay mailbox function, by set-
ting the New York office "A" as a relay station (see the figures below).
<Procedure>
1) Set a relay mailbox in the New York office "A". ( P.115 “Setting up relay mailbox”)
2) Transmit the original from the Los Angeles office to the relay mailbox in the New York office
"A". ( P.122 “Sending data in confidential / bulletin board mailbox (remote hub)”)
