Name the ITU standard that defines the interface between a data terminal device and a packet switching network.
Name the ITU standard that defines the interface between a data terminal device and a packet switching network.
The correct option is C X.25
X.25 the ITU standard
that defines the interface between a data terminal device and a packet
switching network.
X.25 is an ITU-T standard
protocol suite for packet switched wide area network (WAN) communication. An
X.25 WAN consists of packet-switching exchange (PSE) nodes as the networking
hardware, and leased lines, plain old telephone service connections, or ISDN
connections as physical links.
X.25 was originally
defined by the International Telegraph and Telephone Consultative Committee
(CCITT, now ITU-T) in a series of drafts and finalized in a publication known
as The Orange Book in 1976.
X.25 networks were
popular during the 1980s with telecommunications companies and in financial
transaction systems such as automated teller machines. However, most uses have
moved to internet protocol (IP) systems instead. X.25 is still used (e.g., as of
2012 in the credit card payment industry) and available in niche applications.
