INTERFACE BETWEEN DATA TERMINAL EQUIPMENT (DTE) AND DATA CIRCUIT-TERMINATING EQUIPMENT (DCE) FOR TERMINALS OPERATING IN THE PACKET MODE AND CONNECTED TO PUBLIC DATA NETWORKS, DESIGNED FOR EFFICIENCY AT HIGHER SPEEDS
The purpose of this Recommendation is to specify procedures to be used for supporting X.25 compatible services at higher access speeds than Recommendation X.25 itself. Also, in order to add a new flexibility regarding the trade-off between error correction and variations of propagation delay, it includes a non-assured data transfer option.
