4.1 Troubleshooting services and connectivity
This chapter documents how to troubleshoot service and general connectivity
problems when there is no associated alarm condition. See chapter 3 for information
about troubleshooting a service using 5620 SAM alarms.
STM OAM diagnostics for troubleshooting
You can use the 5620 SAM Service Test Manager, or STM, OAM diagnostic tools
to troubleshoot a service or transport. The STM provides the ability to group OAM
diagnostic tests into test suites for more comprehensive fault monitoring and
troubleshooting. A test suite can perform end-to-end testing of a customer service
and the underlying network transport elements. The use of test suites is especially
valuable when multiple objects of the same type require testing. Test suites can be
scheduled to run on a regular basis to provide continual network performance
feedback. See the 5620 SAM User Guide for information about using the STM and
creating scheduled tasks.
Sample network
Figure 4-1 shows a network that is used as an example for the OAM diagnostics
procedures in this chapter.
