This chapter provides you with a general but high-level approach to troubleshooting ONS 15454 SONET networks, including the most common problems and issues found during turn-up of an individual node, and network issues. Note Given the great flexibility, multiple types of services, and multiple possible configurations of the ONS 15454, it is not feasible to provide an exhaustive troubleshooting guide in a single chapter of a book. Therefore, for more information, see the "Documentation" section later in this chapter for details on gaining access to the complete ONS 15454 troubleshooting guide and other related documentation. |
