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.




  • 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.
