Chapter 3 Convenient Fax Features
Sub-Address Communication
The Sub-Addressing function allows you 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 center machine supporting a 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 Center Machine to be forwarded to computers on
the network, to Internet fax, or to other fax stations. Refer to
Inbound Routing (see page 134).
