History

Specifies the requirements for a B-UNI applying to cell-based interfaces at 155 520 kbit/s and 622 080 kbit/s. This revision of edition 2 of ETS 300 299 (to be EN 300 299 V1.3.1) includes improvements and simplification of the scrambler mechanism and the OAM cell payload for these systems.
