Fact Sheet

Cisco Cable Troubleshooter 1.0

Cisco Cable Troubleshooter provides a graphical, portable application for diagnosing a hybrid fiber coaxial (HFC) network. This tool enables a radio frequency (RF) technician to quickly isolate plant and provisioning problems, as well as to characterize upstream and downstream trouble patterns. A technician can also identify "flapping" cable modems or set-top boxes---those experiencing persistent connectivity problems.

Cisco Cable Troubleshooter is part of the end-to-end Cisco solution for managing cable and multiservice networks. This solution also includes the Cisco Cable Manager product, which provides fault, performance, and configuration management for Cisco cable solutions. Both of these new products complement the CiscoWorks solution, which provides baseline management capabilities for Cisco routers and the Cisco Subscriber Registration Center (CSRC) tool for provisioning cable modems.


  • Network operations center (NOC)---Cisco Cable Troubleshooter is an ideal solution for remote monitoring of the HFC plant and cable modems connected to a Cisco uBR7200 series cable modem termination system (CMTS). The real-time status summary and cable modem flap list enable NOC technicians to view related problems (see Figure 1), prioritize them, and resolve them appropriately.

  • Headend or remote site---Technicians working at a headend or other remote site can use Cisco Cable Troubleshooter with a laptop computer and network connection. By viewing the same status information as NOC technicians, a field technician can speed problem resolution and ease maintenance of the cable plant.
