Standard for the transmission of IP datagrams over public data networks

RFC 877 September 1983 Transmission of IP Datagrams Over Public Data Networks 2.2 Features of X.25 not discussed in this document are not used. For example, interrupt packets and the D bit (indicating end-to-end significance) are not used. 2.3 Negotiable features (facilities) of X.25 are allowed. For example, sites are free to negotiate larger packet and window sizes. 2.4 Some sites, such as CSNET sites, may attempt to open multiple virtual circuits to a single site. Sites should attempt to handle such incoming calls gracefully: transmit on the additional circuits if possible and accept incoming datagrams from them, but do not accept the CALL REQUEST, only to immediately close the connection or ignore datagrams transmitted on such circuits.
