RAD Introduces G.SHDSL.bis Solution with the Market's Most Comprehensive Variety of Interfaces

14th November 2006: At ITU Telecom World 2006 in Hong Kong, RAD Data Communications will premier its new ASMi-54 modem with G.SHDSL.bis and EFM technologies, the next generation in SHDSL technology, to provide up to 22.8 Mbps of bandwidth.

The ASMi-54 uses G.SHDSL.bis technology to transmit up to 5.7 Mbps of bandwidth point-to-point over each copper pair with EFM bonding, which enables each link to synch at a different rate. The modem may be ordered with two, four and eight-wire options, yielding a total bandwidth of 22.8 Mbps. "EFM bonding ensures that a failure or addition of a link doesn't drop the the traffic being transmitted over the other wires in the group, nor is the capacity of the group decreased when a new link is added at lower rate," explains Meira Erez, Product Line Manager at RAD Data Communications. "This is particularly relevant for operators offering Ethernet services in the First Mile where fibre is absent or impractical to install," she continues. "The ASMi-54 G.SHDSL.bis modem is also appropriate for the rapidly growing number of utilities, transportation networks and enterprises requiring this bandwidth niche for their own applications."

Most notably, the ASMi-54 offers a comprehensive variety of interface options, which is a rarity in comparison to other G.SHDSL.bis devices now on the market. These include E1, T1 and serial ports such as V.35 and X.21, as well as one Ethernet port or four Ethernet ports with an integrated switch. "No other vendor offers this winning combination of multiple services, distance, high bandwidth, and symmetric data transmission in a compact, one box solution," Erez notes.

The ASMi-54 G.SHDSL.bis modem implements the IEEE's 802.1p and 802.1q standards to provide VLAN-tagging with four levels of prioritisation, enabling carriers to offer differentiated Ethernet services. VLAN tagging can also be employed to separate traffic, ensuring transparency of the customer traffic and bolstering security of management traffic. Advanced remote management and DHCP-client support for easy plug-and-play installation facilitate configuration and also speed up deployment of new Ethernet services. In addition, diagnostic tools for quick identification and isolation of TDM and Ethernet network problems reduce operational costs and system downtime.
