| Sync 201 | SONET/SDH Transmission Considerations |
This course describes how the mapping rules for SONET/SDH signals accommodate different types of payloads, and how the pointer
mechanism contributes the necessary flexibility for handling frequency differences at the cost of some added phase noise.
|
| Sync 202 | Standards Families |
One of the main drivers for highly accurate frequency control in digital networks is interworking between different local,
national and international networks. In addition, interworking between different service-based networks and their network
elements is increasingly important. The rules and procedures that are necessary to support high-quality timing performance
across and between the different networks are the subjects of many standards documents, controlled by several different standards
forums. This course gives an introduction to the main standards groupings and the relationships between their important specifications.
|
| Sync 203 | Clock Specifications |
In Sync 203 we address the parameters and functional characteristics that are invoked to describe individual clock
assemblies and constrain their performance. The entire family of clocks that are specified for the different building blocks
(introduced in Sync 100 courses) that comprise a synchronous network are discussed.
|
| Sync 204 | Interface Performance Standards |
The task of specifying timing performance at network-to-network and user-to-network interfaces is addressed in Sync 204.
The parameters that have been introduced for describing synchronization performance are discussed and the values adopted for
various applications are considered.
|
| Sync 205 | Monitoring Principles and Processes |
Determining the health of the synchronous network and correcting any unacceptable conditions is a challenge, given the
distributed nature of synchronization's cause and effect relationships. Some of the tools and procedures available to
the network operator for maintaining high-quality sync performance are discussed in Sync 205.
|
| Sync 206 | Monitoring Principles; Advanced Techniques |
In Sync 206 we take a more detailed look at sync performance parameters and indicators, and discuss their application to
understanding the behavior of "real-world" synchronization distribution conditions. Instrumentation that is available for
collecting and interpreting sync performance data are also considered.
