82159-2 is a technical standard for Ethernet services. It is used to define the parameters of an Ethernet link used to connect two nodes. The standard defines the physical layer characteristics, the protocols of the data link layer, and the maximum bandwidth of an Ethernet link. It is a part of the IEEE 802 series of standards.

The application field for this standard is wide-ranging. It can be used by businesses, universities, research laboratories, and other organizations to create a customized network. It is often used in combination with other standards to provide distributed storage and computing, network management, and data compression solutions.

The working principle of the 82159-2 standard is based on the principles of multiplexing. Multiplexing is the process of combining analog signals into a single digital signal. The multiplexed signal is translated into a serial stream of Ethernet frames according to the IEEE 802 standards. This allows the frames to be sent over different media types, such as fiber, copper, and wireless. The frames contain the networking information required to establish and maintain the connection.

The 82159-2 standard also defines the physical layer characteristics of an Ethernet link. This includes the type of physical connections such as shielded twisted-pair, coaxial, and fiber. This information is used to select the appropriate hardware for the link. Additionally, the parameters of the physical layer define the maximum speed and distance of an Ethernet link.

The 82159-2 standard also defines the protocols used for the data link layer. These protocols provide reliable communication between nodes by detecting and correcting errors in frames and packets. Examples of data link layer protocols include media access control (MAC), virtual local area network (VLAN), and address resolution protocol (ARP).

Finally, the 82159-2 standard specifies the maximum bit rate capability of an Ethernet link. This is known as the bandwidth. The standard provides various values for the bandwidth depending on the media type, physical connection type, and other factors.

In conclusion, the 82159-2 standard defines the parameters of an Ethernet link used to connect two nodes. It is used in a wide range of applications and is often used in combination with other standards for distributed storage and computing, network management, and data compression solutions. The standard includes information regarding physical layer characteristics, data link layer protocols, and the maximum bit rate of an Ethernet link.
