“I anticipate Proxilliant’s solution will enable us to be proactive about keeping our plant in the best shape for delivering our advanced two-way services.”
In late 2005, Time Warner Cable initiated a trial of Proxilliant’s Cable Access Management System in its high-profile system in Brooklyn, New York to evaluate the service management solution’s ability to increase bandwidth capacity by reducing ingress and to provide a view into overall network health. Time Warner Cable is the second largest cable operator in the U.S., with more than 10.9 million basic subscribers and robust growth in its all-important digital voice service.
System personnel from Time Warner Cable installed the CAMS Dynamic Ingress Blockers deep in the HFC network and the CAMS Service Health Manager software in the head-end, bringing service and network visibility well beyond the node level, to clusters of 24 subscribers.
The results were compelling. A permanent reduction in noise level in the trial area was in the 7-10 dB range, establishing the headroom for the transition from QPSK to 16 QAM and an effective doubling of upstream bandwidth capacity. With dIbs deployed deep in the network and working in concert with the Service Health Manager, Proxilliant’s solution enabled system personnel to identify opportunities for improvements in unity gain balancing and to isolate the on-going ingress issue areas to three clusters of 24 subscribers. Trial results show that CAMS has the potential of reducing troubleshooting time and cost by a dramatic 75 percent. CAMS also demonstrated how it was able to maintain a high level of service performance to the broader trial area as it isolated the specific problem areas.
"I anticipate Proxilliant’s solution will enable us to be proactive about keeping our plant in the best shape for delivering our advanced two-way services. The real-time and continuous view and management of ingress and the view into overall network health have proven to be critical," said Vince Pombo, VP of Engineering for Brooklyn and Queens.
