It is upgrading its entire HFC network to support the new downstream extended frequency ranges defined in the DOCSIS 3.
Mike Semmel, mapping supervisor, SECTV, said: "The seamless database structure of Bentley's HFC network engineering solution gives us an end-to-end perspective of our system that is simply not available from individual drawings, maps, and spreadsheets.
The two-way infrastructure consists of a multimedia terminal adapter (MTA) located at the customer premises, a cable modem termination system (CMTS) located in the cable headend communicating over an HFC network, as well as the iMerge NCSG and class 5 switch.
It is becoming increasingly expensive to break through each successive bandwidth bottleneck in the HFC network and it is now clear that the HFC network needs to evolve.
Consequently, this should lead to an evolutionary transformation of the HFC network to FTTH.
There are two HFC network operators in Australia, Telstra and Optus, both serving customers in the large major metropolitan centres.
Telstra will continue to deliver Foxtel pay TV services through continued access to the HFC network negotiated with NBN Co.
Optus will continue to supply services to customers using its HFC network in areas where the NBN is still to be built or customers have yet to be migrated.
StarHub operates its own nation-wide HFC network that delivers multi-channel cable TV services (including digital cable), voice, and Internet access for both consumer and corporate markets.
The packet voice is passed over the HFC network to the subscriber where an EMTA from Scientific Atlanta (Webstar 2203) provides the POTS gates.
The NSG 9000 provides a new level of density and performance for on-demand delivery that bridges the IP narrowcast backbone and traditional HFC network.
With Harmonic's standards-based solutions, operators can improve network efficiency and scalability by expanding the utilization of IP within the cable infrastructure while preserving the existing HFC network investments.
