Efficient (Efficient Networks, Inc. ) : 5950 SDSL / SHDSL Gateway

5950 SDSL / SHDSL to Ethernet Gateway

Efficient's 5950 is an SDSL / SHDSL (Symmetric High-density Digital Subscriber Line) Gateway. It combines the functions of a DSL modem, managed 8-port 10/100 Base-T Ethernet switch, ICSA-compliant firewall, VPN security appliance, and full-featured router-all in a single chassis. The Efficient Networks 5950 SDSL/SHDSL Business Gateway can be configured for either SDSL or SHDSL via a simple command. The ability to offer either access method through a single device facilitates the transition from SDSL to SHDSL. The reasons for migrating to SHDSL are compelling. Compared to SDSL, SHDSL has 30% more reach, with translates to at least a 60% larger coverage area. With up to 2.3Mbps symmetric bandwidth on a single copper pair, SHDSL supports higher-bandwidth services, such as Voice over IP. And its standardization eliminates traditional interoperability problems between Digital Subscriber Line Access Multiplexers (DSLAMs) and customer premises equipment.

Chipset Globespan Features SHDSL ITU G.991.2 Annex A or B; G.hs ITU G.994.1 Supports symmetric line rates 192Kbps to 2,312Kbps downstream and upstream Embedded Operations Channel (EOC) support Built-in 8-port 10/100 Base-T Ethernet switch with link status LED for each port IP Quality of Service (QoS) - By differentiating between types of IP traffic and giving priority to the most urgent or time-sensitive, the service provider can offer differentiated classes of service - not possible until now with DSL services. High availability - The Efficient Networks 5950 Business Gateway supports high availability with a redundant router configuration or dial backup functionality. The gateway automatically establishes a backup connection if it detects a DSL link failure.
