2.4.1 SEP/SUB/PWD/SID

In 1996, ITU-T introduced the following protocol signals into 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.
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, PWD and SID codes in
transmission or for polling reception, but it is not capable of receiving PWD and SID
codes. If the machine receives one of these frames, the machine disconnects.
