Chapter 3 Convenient Fax Features
Sub-Address Communication
The Sub-addressing function allows further routing, forwarding, or relaying of document(s) to the
desired destinations when used in combination with Internet Fax.
What is Sub-Addressing?
Sub-addressing is a T.30 communications protocol recommended by ITU-T.
• A centre machine supporting the Memory feature is required on the fax network to implement sub-
addressed communications. For more details, contact your local authorized Panasonic dealer.
• In a sub-addressed communication, the sub-addressing information must be checked between the
sender and the receiver beforehand (sub-address is limited up to 20 digits).
• On this machine, select “Sub Address Transmit” from the “More Menus” to initiate sub-addressed
communication.
• Sub-addressing allows documents received by the centre machine to be forwarded to computers on
the network, Internet fax, or other fax stations. Refer to
Inbound Routing (see page 138).
