2.4.5.3
In power down state, (see chapter 3.3.1) only an analog level detector is active. All clocks,
including the IOM interface, are stopped. The data lines are "high", whereas the clocks are
"low".
An activation initiated from the exchange side (Info 2 on S bus detected) will have the
consequence that a clock signal is provided automatically.
From the terminal side an activation must be started by setting and resetting the SPU bit in the
SPCR register (see chapter 4).
2.4.6
The transmit and receive bit clocks are derived, with the help of the DPLL, from the S-interface
receive data stream. The received signal is sampled several times inside the derived receive
clock period, and a majority logic is used to additionally reduce bit error rate in severe
conditions (see chapter 2.4.5). The transmit frame is shifted by two bits with respect to the
received frame.
The output clocks (DCL, FSC1 etc.) are synchronous to the S-interface timing.
