Korea-based Hanaro Telecom said today that it has deployed Harmonic’s EdgeQAMs to ramp up subscribers’ broadband bandwidth.

Hanaro, which has approximately six million cable and DSL customers, is using Harmonic’s Narrowcast Services Gateway 9000 Universal EdgeQAM.

Hanaro's wideband DOCSIS 2.0B modular cable modem termination system (M-CMTS) service with channel bonding, capable of delivering 150 Mbps or more, is fully operational.

The NSG 9000's integrated DOCSIS 3.0 timing interface (DTI), which maximizes channel capacity by enabling clock synchronization in M-CMTS applications, was a critical factor in Hanaro's decision, according to Harmonic. The RF performance of the NSG platform, which exceeds the DOCSIS RF Interface (DRFI) specification in several RF parameters, was also a key differentiator, as was the NSG's capability to be implemented in a Direct-to-Edge cable IPTV environment.

"Hanaro is committed to deliver a superior broadband data service, and the Harmonic solution allows us to do so with very little additional investment or operating costs," said Chan Woong Park, SVP of the Network Technology Division at Hanaro. "Harmonic's NSG 9000 has been widely deployed throughout our network, and our transition to a wideband M-CMTS service has been very smooth and efficient."
