H31-341_V2.5 · Question #913
In unstructured emulation mode (SAToP), WS-OTN equipment provides the function of compressing idle 64 Kbit/s time slots in E1 signals to save transmission bandwidth.
The correct answer is B. False. B is correct because SAToP (Structure-Agnostic Transport over Packet) is explicitly structure-agnostic - it treats the entire E1 signal as an undifferentiated, continuous bitstream and has no awareness of individual 64 Kbit/s time slot boundaries or their content.

Explanation
B is correct because SAToP (Structure-Agnostic Transport over Packet) is explicitly structure-agnostic - it treats the entire E1 signal as an undifferentiated, continuous bitstream and has no awareness of individual 64 Kbit/s time slot boundaries or their content. Since it cannot distinguish active slots from idle ones, it cannot selectively compress or suppress idle channels; it simply encapsulates the raw bitstream into packets wholesale. A is wrong because idle time slot compression requires structure-aware processing (like CESoPSN does), which directly contradicts the "unstructured" nature of SAToP.
Memory tip: The "S" in SAToP stands for Structure-Agnostic - if it can't see the structure, it can't touch individual time slots, so compression of idle slots is impossible by definition.
