Additional resources for Sonet or SDH Demystified
SONET Basics Chapter 2 54 carefully thought-out, and as a result, offer network providers the ability to manage their resources with enormous granularity across the wide area. Section Overhead The Section Overhead comprises nine bytes, as shown in Figure 2-14. Their individual functions are described in the following section. Remember the reason for the Section Overhead: it contains information that every device in the network uses, from the originating device all the way to the destination device.
Timing will be discussed in more detail in a later section of the book. A final note about the H3 byte: it represents an integral part of the payload pointer function and therefore, like the pointer itself, must be provided for every STS within an STS-N frame. However, unless it carries justification information, it is ignored. B2: BIP-8: Sound familiar? B2 is another bit-interleaved parity byte and is used to carry error-checking information. It calculates its value based on the Line Overhead (it does not include the Section Overhead) and payload of the previous frame before it is scrambled for transmission.
