RAD value-added reseller, Ariel Network Solutions is offering a new modem (the HCD-E1) which integrates data, voice and LAN services over a single n x 64 kbps link using HDSL technology. The modem extends transmission over existing copper plant to 4.5 km, providing immunity to background noise and compensation for poor line quality. "The HCD-E1 enables carriers to provide HDSL-quality links at n x 64 kbps data ratesup to E1," says Mike Fisher, product manager at ANS. "They can now connect their end-users` PABX equipment, routers and other digital data devices over a single line, saving on copper plant." HCD-E1 supports one or two different data ports as well as a sub-E1 drop and insertport for PABX connectivity. The unit allows for V.35, X.21 and other digital data interfaces. It is also available with a built-in Ethernet bridge. The modem operates opposite RAD`s rack-mounted HDSL products, including the HTU-E1 Termination Unit (E1 interface) and the HTU-2 Access Unit (2 Mbps G.703 interface), so that the carrier has a complete managed local loop solution from a single vendor. "This results in a cost effective solution for corporate connectivity because the HCD-E1 links the customer premises to the carrier backbone with one dual twisted pair line. Therefore, the overall service is less expensive," adds Fisher. The HCD-E1 has enhanced diagnostic capabilities, real-time alarm indication and can be managed from a central site rack by an SNMP network management station.
