Nuera, Mahi Showcase New Gateway Gear


Nuera Communications Inc. is introducing a new media gateway for voice-over-Internet protocol deployments, while Mahi Networks makes its transport-solution debut at this week’s Society for Cable & Telecommunications Engineers Cable-Tec Expo in Orlando, Fla.

The Nuera Orca BTX-4K provides up to 4,032 voice ports over six DS3 (digital subscriber signaling) interfaces, all housed in a five-inch chassis.

The product delivers new levels of density and reliability, according to director of product marketing Joe Matibag.

The gateway features voice processing redundancy, hitless failovers and software and capacity upgrades, he added.

The product is designed to be PacketCable-compliant and will be part of Cable Television Laboratories Inc.’s certification wave 31, Matibag said.

The unit costs $175,000 with a one-DS3 configuration, which covers 672 ports and can handle 2,500 to 4,000 subscribers.

The three-DS3 model costs $375,000 and the fully loaded, six-DS3 model costs $675,000, he said.

The product is sold with Nuera’s NetConductor software package, which starts at $30,000.

Matibag said the media gateway has a 50-millisecond IP recovery time and draws 250 watts of power.

Nuera has raised over $80 million in four funding rounds since its inception in 1997. Last week, it announced a deployment with Cox Communications Inc. for its VoIP media gateway.

Cox and Comcast Corp. have been investors in the company.

Last month, the company announced a re-seller agreement with Nortel Networks Inc., incorporating its Orca media-gateway product line into Nortel’s telephony solutions.

Mahi Networks is making its formal introduction to the cable business this week at SCTE. The company makes multi-service transport and switching solutions.


Its two main products are its Mi7 broadband-convergence gateway product, which packages time-division multiplex switching, transport and aggregation for triple-play services, and its Vx7 automated dense wave-division multiplexing service.

The Mi7 is designed for inside-the-plant distribution, said Mahi CEO Chris Rust, while the Vx7 sits on the trunk side on the access network.

The Vx7 has a wavelength-selectable switch with tunable lasers, and dynamic gain control with rapid transient response. It also features an all-optical backplane with tunable lasers.

Rust said the Mi7 solution can greatly reduce the lower rack space used for transport equipment at a cost that’s 50% cheaper than today’s solutions.

Systems as small as 100,000 subscribers would find the product cost-effective, he said.

“It would work for a medium-sized MSO, even in a tier-2 city,” he said.

The company bolstered its product line with the addition of Photuris Networks, which made dense wave-division multiplexing gear, and a recent $70 million funding round.

Buckeye Cablevision has deployed the Mi7 platform, and several other MSOs are trialing the product for voice, video and data services, Rust said.

Mahi also said Tim Holzer was joining the company as vice president, global MSO sales.

Also at the Cable-Tec Expo, Tandberg Television will be showcasing its ATSC (Advanced Television Systems Committee)- and DVB (Digital Video Broadcasting)-compliant HD encoder, a new standard-definition encoder and an IP streamer, which can fit up to 10 channels of encoding into a single three-rack unit space.

Ellacoya Networks Inc. will introduce its network intrusion manager module, which allows MSOs to automatically detect and prevent denial of service attacks, worms and viruses in real time.

The product is being integrated with Sourcefire’s intelligent security monitoring system, Ellacoya said.


Ciena Inc., which closed on its purchase of Internet Photonics Inc., will showcase the combination of layer-1 transport with layer-2 packet switching using its CN 4300 managed optical transport and switching platform, combined with its CN 2300 managed optical services multiplexer.

By leveraging transport and switching at the edge and centralizing routing at major headends, MSOs can reduce costs and operational complexity, Ciena said.

Ciena said packet switching could be used for VOD and HDTV transport efficiencies. The switching strategy could also be used for VoIP implementations.

And Metrobility Optical Systems and Corning Cable Systems will show a business-to-business product line developed for Time Warner Cable in Raleigh, N.C.

The solution combines a fiber-to-the-business junction box designed by Corning. It houses Metrobility’s access optical-network unit, which provides Ethernet connections to businesses.

The access unit offers a single-mode, 100-Mb fiber connection between Time Warner’s high-speed network and the local area network of its business customers.

Corning Cable Systems will introduce a new coarse wavelength division multiplexing system using thin-film filter technology The company said the product will be available in various channel counts at 20 nanometer spacing. The company also will display an OptiSource premier fusion splicer for fiber networks.
