A major design goal of SONET is to ensure timing synchronization and equipment operation across the network using what?
Multiple independent clocks
A single master clock
Asynchronous timing protocols
Distributed timing algorithms
What is a key benefit of standardization in fiber optic transmission system equipment within SONET?
Reduced manufacturing costs for a single vendor.
Increased complexity in network design.
Interoperability between equipment from different manufacturers.
Elimination of the need for regenerators.
What is a crucial requirement for SONET's physical specification and frame design regarding signal compatibility?
It must only carry signals from identical tributary systems.
It must include mechanisms to carry signals from incompatible tributary systems.
It must convert all signals to an analog format.
It must prioritize signals from the highest bandwidth sources.
SONET is fundamentally based on which type of multiplexing system?
Frequency Division Multiplexing (FDM)
Code Division Multiplexing (CDM)
Time Division Multiplexing (TDM)
Wavelength Division Multiplexing (WDM)
What is the primary function of regenerators in a SONET network?
To multiplex signals from various sources.
To demultiplex STS signals into destination signals.
To eliminate the effect of additive noise on transmission quality.
To add or drop signals from the multiplexed stream.
