DataMiner To Manage Network And Service Quality On TDC Group’s DOCSIS 3.1 Cable Plant

Tele Danmark Communications Group (TDC Group), Denmark’s largest telecom operator, will deploy Skyline’s DataMiner solution for end-to-end management of its new nationwide DOCSIS 3.1 cable network (Giga COAX).

The TDC Group previously announced plans to upgrade its cable network to provide speeds of 1Gbps with the roll out of Giga COAX. The upgrade is in process and scheduled for significant completion by the end of 2017. Completion will make Denmark the first country to upgrade an entire cable network to Giga COAX 1Gpbs connectivity.

Before the end of 2017, half of TDC Group's 1.3 million households will have access to 1Gbps broadband data and video services using the CableLabs DOCSIS 3.1 technology. Delivering the super-speed requires a challenging network transformation, touching many points both in the network and in the customers’ homes. Moreover, DOCSIS 3.1 also drives significant operational transformations.

The DOCSIS distributed network architecture is gaining momentum in the cable industry for many reasons. One such reason is that it brings digital feeds closer to the subscriber home. However, DOCSIS 3.1 requires the HFC plant meet certain technical specifications. 

Bringing the digital feeds deep into the network also means that the tolerance towards analog impairments that may affect the broadband signals is reduced. DOCSIS 3.1 comes with a rich set of monitoring and performance-oriented data embedded in the network, which facilitate both network optimization and enable effective planning of proactive maintenance. 

DataMiner leverages those tools to create a 24/7 monitoring system that warns the maintenance team early about increasing noise levels, amplitude impairments, modulation error rates, micro-reflections, group delay variations and much more. This enables technicians to correct impairments quickly and cost-efficiently, well before subscribers experience any service degradation or outages.

DataMiner provides sophisticated system measurements and analytics to technicians. The measured data enables network operators to take proactive steps to reduce or eliminate subscriber outages and signal degradation.

"A lot of fine-tuning is needed for the DOCSIS 3.1 configuration in order to achieve optimal performance for each type of service running over the gigabit pipe, be it broadcast TV, on-demand TV, OTT services, voice, or plain broadband connectivity. DataMiner’s Service Quality Management measures and monitors service quality around the clock by pulling data from the entire network, including millions of CPE devices. The big data storage and analytics engine of DataMiner calculates the complex service quality and network performance indexes continuously. And DataMiner also measures and predicts network utilization, which enables TDC Group to provision and deliver the required network capacity at all times,” commented Steven Soenens, Product Marketing Director at Skyline Communications.
