Choose an INCORRECT statement regarding the SONET/SDH technology.
A) SONET/SDH is intended for high speed leased line services on fiber optic cabling.
B) The SONET service is offered on the optical carrier (OC) data rate hierarchy.
C) SONET/SDH uses Time Division Multiplexing to combine lower speed channels to create a bigger pipe.
D) SONET/SDH is widely used by WAN carriers to define the bandwidth of their backbone networks.
E) The SONET infrastructure generally relies on the dual-ring architecture to improve fault-tolerance.

Question

Quizplus · Accepted Answer

SONET/SDH does not use Time Division Multiplexing to combine lower speed channels, instead it uses Synchronous Time Division Multiplexing, where the multiplexing is done based on time slots that are synchronized at both ends of the transmission path. The other statements are correct.
