1. EFM (Ethernet First Mile)

PROSCEND 5600 series is the EFM Based Network Extender which provides a flexible and friendly solution for the Ethernet based services provision to subscribers by the service provider. Additionally, this family of products provides a simple way in a back-to-back deployment to provide point to point configuration. This allows broadband service providers to deploy single DSL lines economically when required for low density geographical areas or during start up phase.

PROSCEND 5600 series provides cost-effectively symmetrical bandwidth at rates up to 22.8 Mbps which allows service providers to deliver friendly Ethernet services rapidly. PROSCEND 5600 series extends the reach of Ethernet services to the sites with no fiber access to by using bonded copper pairs. Designed with standard-based EFM technology (2BASE-TL), the delivery of Ethernet services with PROSCEND 5600 can be deployed quickly on the existing copper plant. It is a nice application for back-to-back connection between remote office and enterprise headquarters

PROSCEND 5600 series implements the management features based on IEEE 802.3ah standard and it enables users to significantly reduce operation expense by eliminating unnecessary transformation between Ethernet and legacy ATM network. As based on user-friendly Ethernet, it saves time and costs because of simple engineering task without additional trainings costs. Packet based technology which architecture utilizes 100% packet transmission technology for optimum throughput and reliability. With a compact form-factor design and optimization for the use over existing copper network, PROSCEND5600 series reduces the initial investment cost and deployment time in delivering higher speed Ethernet service. It provides minimized risk bearing and quick return on investment to service providers and enterprises

PROSCEND5600 LAN port is interoperable with any standard Fast Ethernet interfaces from switches, routers, and NG-SONET/SDH Equipment. PROSCEND5600management interfaces include comprehensive command-line interface (CLI), user-friendly GUI-based Web Browser Interface, SNMP and Telnet.

PROSCEND 5600 series can bond up to 4 pairs and deliver up to 22.8 Mbps Ethernet services to all users within their service area by utilizing existing copper infrastructure and EFM 802.3ah PAF bonding technology. Service Providers and enterprises are able to offer symmetrical high speed connectivity for transparent Ethernet service on DSLAM backhaul, Wireless backhaul, and more.

PROSCEND 5600 Series provides future-proof features meeting Ethernet Quality of Service (QoS) and Class of Service (CoS) requirements by utilizing 802.1q VLAN capabilities, four levels of priorities, traffic flow control and rate control. This traffic management and QoS features enable service providers to offer highly profitable and value-added services to a vast majority of business and institutional sites.
