Section, line, and path errors occur over different spans of the SONET network and between different pieces of equipment.
SONET (Synchronous Optical Networking) is a standardized protocol used in telecommunications to transmit large amounts of data over optical fiber. SONET networks are organized hierarchically into four levels: STS-1, STS-3, STS-12, and STS-48. Each level represents a different data rate, with STS-1 being the lowest and STS-48 being the highest.
When troubleshooting SONET networks, there are several network elements that are used to isolate and resolve issues. The three SONET network elements that are commonly used for troubleshooting are the line, path, and section.
Line: A SONET line represents the physical connection between two network elements. This could be a fiber optic cable or a copper cable. The line is the first element that is checked when troubleshooting SONET networks. If there is a physical issue with the line, such as a break or a loose connection, then the entire network could be affected.
Path: A SONET path is the logical connection between two network elements. The path represents the route that data takes through the network. If there is an issue with the path, then data may not be able to reach its destination. This could be caused by a problem with the routing configuration or a fault with a network element along the path.
Section: A SONET section is the portion of the network that is between two network elements. This includes the fiber optic cable or copper cable and any amplifiers or repeaters that are used to boost the signal. If there is a problem with the section, then the signal may not be able to travel the required distance, or it may become distorted or degraded.
Circuit: A SONET circuit is the logical connection between two endpoints. This could be a voice circuit, a data circuit, or a video circuit. If there is an issue with the circuit, then data may not be able to flow through the network. This could be caused by a misconfiguration of the circuit, a fault with a network element along the circuit, or a problem with the endpoint device.
Segment: A SONET segment is a portion of a path that is between two regenerators. Regenerators are devices that are used to amplify the signal and retime the data. If there is an issue with a segment, then the signal may not be able to travel the required distance, or it may become distorted or degraded.
Therefore, the correct answers to the question are A. line, D. section, and B. path. These three network elements are essential for troubleshooting SONET networks and identifying and resolving issues.
