Summary

This Recommendation covers Physical Layer characteristics for transporting ATM cells at nominal bit rates of 155 520 kbit/s and 622 080 kbit/s over coaxial cable and optical fibre interfaces at the T_B and S_B reference points of the B-ISDN User-Network Interface (UNI). The maximum distance is approximately 2 km for optical fibre and approximately 200 m for coaxial cable.

This Recommendation is part of the I.432 series, and includes references to Recommendation I.432.1 on general characteristics.
