This is an International
Telecommunication Union Telecommunication Standardization Sector (ITU-T)
standard that defines how connections between data terminal equipment (DTE) and
data communications equipment (DCE) are maintained for remote terminal access
and computer communications in public data networks (PDNs). X.25 specifies
LAPB, a data link layer protocol, and packet level protocol (PLP), a network
layer protocol. Frame Relay has, to some degree, superseded X.25. See also
Frame Relay, LAPB, and PLP.
