RAD Shows Premier Solutions for Next Generation Voice, Data and Cellular Transport at CeBIT 2001

At CeBIT 2001, to be held March 22–28 in Hanover, Germany, RAD Data Communications will be presenting access solutions for emerging Next Generation Networks.

Voice and Data Convergence over DSL Lines

The global process of telecommunications deregulation and the unbundling of the Local Loop have generated wide interest in Digital Subscriber Line (DSL) technologies. In an unbundled Local Loop, incumbent operators will be required to open up their local access lines to alternative, competitive carriers.

RAD’s Link Access™ integrated access devices (IADs), such as the LA 140™ being shown at CeBIT, enable alternative carriers to offer high-bandwidth services (for example, analog and digital voice, video-on-demand and high speed “always-on” Internet access) over the incumbent’s existing copper infrastructure. RAD IADs guarantee Quality of Service (QoS) and end-to-end management up to the customer premises. They are interoperable with major DSLAM and Voice Gateway vendor equipment.

Voice over DSL (VoDSL) will enable alternative carriers to diversify services by bundling voice and data over their leased copper lines. “The extra business generated by converged services will lead to new revenues,” predicts Yoram Holtz, Vice President of Marketing at RAD Data Communications, “and this, combined with savings in infrastructure and provisioning, will result in increased profitability.” (See the interview with Yoram Holtz for more details on RAD’s VoDSL IADs.)

TDM over IP Gateway with Service Management

RAD’s IPmux™ family of TDM over IP (TDMoIP) gateways, introduced last year at CeBIT, now offers a carrier-class service management platform that allows the carrier to integrate the TDMoIP circuit extension service in its provisioning platform. Service management facilitates service provisioning, monitoring and statistics collection. “The service management platform is a powerful tool for carriers,” explains Holtz. “Equipment vendors typically supply element management applications for their products, but from the carrier’s perspective, this is not enough,” he continues. “Only with service management can the carrier control, monitor and provision services.”

The IPmux has also been upgraded to accommodate E3/T3 speeds for trunking services. The IPmux takes TDM data streams from E1/T1 or E3/T3 ports and converts them to IP packets, which are converted back to circuit-switched traffic at the destination site. The overall effect of the IPmux is to allow transparent connectivity over the new generation of switch-based packet networks, both in the carrier and the corporate environments. In so doing, the product allows legacy voice and data to be transported over IP without requiring any higher layer processing such as that provided by IP gateways and without the need to swap out existing equipment.

AMTS Eases Cellular Operators into 3G RAD’s

RAD's AMTS (Access for Mobile Transport Solutions) is designed to facilitate migration to next generation mobile networks. Based on RAD’s ACE™ family of multiservice access concentrators and IPmux family of TDMoIP gateways, AMTS will enable co-location of GSM services and third generation UMTS traffic.

“AMTS will enable cellular operators to offer high-bandwidth IP or ATM transmission, with integration of additional services such as voice, video, data and Internet surfing,” explains Holtz. “At the same time, AMTS provides a sure migration path to support legacy equipment and services throughout the transition stage, which may last several years,” says Holtz.

“Eventually, cellular operators will become alternative carriers in their own right,” Holtz predicts, “and will offer services over the Wireless Local Loop or LMDS. Wireless unbundled services will demand the same requirements for co-location, so RAD’s AMTS will remain a logical and cost-effective solution well into the future.”
