Figure 25
The transmit and receive clocks are supplied at pins RxCLK and TxCLK. The Octet
synchronisation signals are supplied at pins OSR and OST. The "strobe signals" for
active time slots are generated internally by the time slot assigner blocks (TSA)
independent in transmit and receive direction.
Bit fields ’TCC’ and ’RCC’ are ignored because of the constant 8-bit time slot width.
