238 Chapter 9: Troubleshooting High Speed Data Service Process Automation Yields Measurable Improvement High-speed data service turn-up—done properly—is an exacting and time-consuming task. To address the many potential obstacles, leading providers are adopting automated workforce management solutions that interface directly with smart instruments capable of addressing all scenarios technicians may encounter. The JDSU HST-3000 Handheld Services Tester, for example, provides automated testing capability that includes copper physical layer, xDSL, and IP service layer checks. This combination allows technicians to more easily distinguish between core and access network problems. In addition, the automation allows rapid problem isolation to the appropriate layer, (e.g., quickly identifying a packet loss issue and correlating it to a noise problem caused by pair imbalance at the physical layer). During the test, a vast array of data, including IP, DSL, and copper loop performance, is gathered for further analysis and record keeping. These instruments can be integrated with Web-based tools to tie the efforts of field technicians with the tasks of central office staff, yielding unprecedented advancements in operational efficiency.
Chapter 9: Troubleshooting High Speed Data Service Select and initiate test and the instrument automatically progresses thru a sequence of tests to verify DSL synch & performance, PPP authentication, IP connectivity and IP data rate. Figure 9.8 HST 3000 automated DSL testing 239
