PAD—Packet Assembly/Disassembly. A service specified for X.25 networks and standardized by the
International Telecommunication Union (ITU). It defines a way for asynchronous character-mode
terminals (DTE-Cs) to use a packet switching network.

terminals (DTE-Cs) to use a packet switching network.
subaddress—The second of two subfields in an X.121 address. Permissible subaddress values run from
zero through 99, and are padded with leading zeros when necessary. Valid examples therefore include
00, 09, 10, and 99. For PAD connections, either the physical port’s number or the line’s absolute number
is used as the subaddress.

X.25—The ITU Recommendation that defines the interface and packet formats for "X.25 Networks".
X.28—The ITU Recommendation that defines the user interface for an X.25 PAD. All user-entered
commands and responses by the PAD are defined here. Users can initiate connections to X.25
destinations and set parameters.
