Back to top Troubleshooting Cable Access Infrastructures (ACC-311) To ensure that cable networks are as reliable and available as the telephony business at 99.999 percent, real problems must be distinguished from insignificant events. By constantly observing and documenting large quantities of return performance data, systems can quickly identify and separate real problems to allow operators to respond before outages occur. This also enables providers to determine when to perform segmentation for better availability. Nonintrusive and in-service testing is virtually required for return-path troubleshooting and monitoring in today's cable plants. To achieve this goal, operators must be able to compare noise and ingress from the head-end fiber receiver to that on a test-point in the field while in the field; observe the in-band response of an active Time-Division Multiple Access (TDMA) signal without interfering with it; perform constant spectrum analysis to detect developing problems before they escalate into actual outages; cross-reference cable modem termination system (CMTS) information in the form of "flap lists" and debug commands to real-world, physical problems (cable troubleshooter product); and use cable modems as a tool for return-path monitoring.
