RAD Data Communications has released its new ASMi-54 SHDSL.bis modem, which provides up to 22.8 Mbps of bandwidth using bonded copper pairs.
The ASMi-54 SHDSL.bis modem transmits multiple point-to-point links of up to 5.7 Mbps each, with each link synchronized at a different rate. The modem may be ordered with two, four or eight-wire options to yield a total bandwidth of 22.8 Mbps.
"The ASMi-54 is designed so that a failure or addition of a link doesn't drop the traffic being transmitted over the other wires in the group, and the capacity of the group is not 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 seeking to offer Ethernet services where fiber is absent or impractical to install," she continues. "The ASMi-54 SHDSL.bis modem is also appropriate for the rapidly growing number of utilities, transportation networks and enterprises with their own applications that demand this otherwise hard-to-find bandwidth niche over existing copper infrastructure."
Most importantly, the ASMi-54 will offer a comprehensive variety of interface options, which is a rarity in comparison to other SHDSL.bis devices now on the market. These include E1/T1, as well as four Ethernet ports with an integrated switch. "No other vendor offers this winning combination of bonding, multiple services, distance, high bandwidth, and symmetric data transmission in a compact, one box solution," Erez notes.
The ASMi-54 SHDSL.bis modem implements the IEEE's 802.1p and 802.1q standards to provide VLAN tagging with four levels of prioritization, 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 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.
