Cincinnati Bell was conducting the trial on behalf of the newly formed Residential Access Carrier Consortium (RACC), a consortium of carriers from North America, Europe, and Latin America, which aims to address the need to improve broadband in suburbs, semi-rural areas, and rural areas using Genesis solutions.
"DSL Rings® has been put to the test in its most challenging trial to date with a major US carrier, where world-class solutions and fast broadband speeds are paramount," said Stephen Cooke, founder and chief technology officer of Genesis Technical Systems. "Genesis's technologies enable carriers to increase broadband throughput and deliver enhanced services over their existing network, eliminating the need to lay fiber to every home."
DSL Rings consists of a Convergence Node (CN) in the physical network; a Home Gateway (HGW) in each home; and Exchange Gateway Software, which monitors all rings deployed throughout the network, installed at the local central office.
The types of services tested and validated included: rate vs. range; multicast; dynamic bandwidth allocation, i.e., equity; exploitative individual data transmissions, i.e., demonstrating that individual households could have access to the full 400 Mb/s; and Plain Old Telephone Service (POTS).
The tests carried out on the backhaul network infrastructure were completed using copper cables used by Cincinnati Bell in its normal network deployments. Backhaul network bandwidths were measured across a maximum of 12 pairs from the digital subscriber line access multiplexer (DSLAM) to the convergence node (CN), at distances ranging from 300-900 meters, in increments of 150 meters.
The trials tested the distribution around the ring to up to 12 HGWs. These local access routes were connected with standard copper cables, as used by Cincinnati Bell in its network. The network range between the CN and the HGWs was initially 48–152 meters.
The backhaul network generated aggregate bandwidth (upstream and downstream) of up to one gigabit. The access network generates total bandwidths of up to 400 Mbps, providing more than enough bandwidth capacity for residential use. Test results also show that bandwidth of up to 600 Mbps is available to support additional services, such as small cell deployments.
"We serve three states spanning 3,800 square kilometers. We're very proud of our network and what it delivers to our customers, both in the office and at home," said Tom Simpson, Chief Technology Officer of Cincinnati Bell. "This trial has shown and proven the ability to deliver more than enough bandwidth to customers served by even the oldest parts of our network. Since the FCC recently changed the definition of broadband to increase the minimum speed, these results are good news for those looking to upgrade their infrastructure to meet the massive increases in bandwidth demand.".
"The results of the Cincinnati Bell trial demonstrate the importance of DSL Rings and the opportunities this solution offers to members of the Residential Access Carrier Consortium," commented Peter Khoury, CEO and General Counsel at Genesis Technical Systems. "DSL Rings offers RACC members, including those receiving Connect America Fund II (CAF II) service, the opportunity to deliver significant broadband improvements to customers who currently receive limited service on their existing networks. Conducting this DSL Rings trial in North America is another important achievement for Genesis.".
Cincinnati Bell provides integrated communications solutions, including local and long-distance voice, data, internet, and high-speed video, keeping residential and business customers in the Cincinnati and Dayton metropolitan area connected to each other and the world. The company was originally formed in 1883 and laid its first underground cable in 1891.
