Multiplexing is synchronous TDM
SONET (Synchronous Optical Network) is a standard for transmitting digital data over optical fiber networks. It provides a flexible and efficient way of multiplexing different types of data streams into a single high-speed optical signal. In SONET, data is organized into frames, and these frames are sent in a synchronous manner.

Frames of lower rate can be synchronously time-division multiplexed into a higher-rate frame
One of the key features of SONET is its ability to multiplex frames of lower rates into a higher-rate frame. This is achieved through synchronous time-division multiplexing (TDM), where multiple lower-rate frames are combined into a single higher-rate frame. This allows for efficient utilization of network bandwidth and enables the transmission of different data streams at different rates.

All clocks in the network are locked to a master clock
Another important aspect of SONET is the synchronization of clocks. In a SONET network, all clocks in the system are locked to a master clock. This ensures that all data streams are synchronized and can be multiplexed and demultiplexed accurately. The synchronization of clocks is crucial for maintaining the integrity of the data transmitted over the network and for avoiding timing issues.

Not true about SONET
The correct answer is option 'D' - none of the mentioned. This means that all the statements mentioned about SONET are true. SONET allows for synchronous TDM multiplexing, where frames of lower rates are combined into higher-rate frames. It also ensures that all clocks in the network are locked to a master clock, providing synchronization and accurate multiplexing/demultiplexing of data.

In conclusion, SONET is a powerful standard for transmitting digital data over optical fiber networks. It supports synchronous TDM multiplexing and ensures clock synchronization throughout the network. These features make SONET an efficient and reliable solution for high-speed data transmission.
