This Interim European Telecommunication Standard (I-ETS) defines a 25,6 Mbit/s physical layer interface to be applied at the S B reference point of the reference configurations of the Broadband Integrated Services Digital Network (B-ISDN) customer access as defined in ITU-T Recommendation I.414 [2]. The physical layer is divided into a Physical Media Dependent (PMD) sublayer and a Transmission Convergence (TC) sublayer. The PMD sublayer provides the definitions for the transmitter, the receiver, timing recovery, media interface connector and the channel transmission media. The TC sublayer defines the line coding, scrambling, data framing and synchronization
