X.75 was originally designed for packet-switched signaling systems in public networks to provide data transmission services. But it is now also used as the link layer for telematic services (as defined in T.90) in ISDN. These services include both ISDN circuit-switched mode (DTE-DTE communication) and ISDN packet-switched mode (DTE-DCE communication).
