FAX COMMUNICATION FEATURES

2.4 FAX COMMUNICATION FEATURES
2.4.1 SEP/SUB/PWD
In 1996, ITU-T introduced the following protocol signals as the T.30
recommendations. These signals enable confidential transmission and secured
polling between machines produced by different manufacturers.
SEP (Selective Polling): This signal informs the other terminal of a polling ID to
enable secured (ID) polling or to select a document to poll.
Up to 20 digits or characters can be sent in a SEP frame.
PWD (Password): This signal informs the other terminal of a password to enable
extra security.
Up to 20 digits or characters can be sent in a PWD frame.
SUB (Sub-address): This signal informs a sub-address of a destination. Some fax
servers use this information to route a received fax message to a specific address
in the local network.
Up to 20 digits or characters can be sent in a SUB frame.
SID (Sender ID): This signal informs the other terminal of the sender ID to identify
the transmitter.
Up to 20 digits or characters can be sent in a SID frame.
NOTE: SID is not available with this machine.
The ITU-T recommendation only clarifies transmission requirements, and does not
specify reception requirements. How the receiving terminal treats these signals
varies with receiver terminal and manufacturer.
This machine is capable of sending SEP, SUB and PWD codes in transmission or
for polling reception, but it is not capable of receiving these codes. If the machine
receives one of these frames, the machine will ignore it.
