Physical Interface
OBSAI offers 4 rates based on a multiple of 768 Mbit/s. All OBSAI rates use
8B/10B line coding. Scrambling is mandatory for the 6.1Gbit/s rate. When
using OBSAI with Framed L2, the line rate and scrambling are normally
negotiated following the operation of the TX and RX state machines at the
BTS and RRH nodes.
