Proscend Communications Inc.

Proscend 56OOI Series EFM Network Extender is designed to provide bonded high-speed Ethernet First Mile services over SHDSL on existing copper infrastructure. It is a bridge mode modem that delivers Ethernet services<br />
with symmetrical bandwidth at rates up to 15.3 Mbps/Pair (TC-PAM 128). Implemented based on IEEE 802.3ah EFM standards for advanced performance and management features, 56OOI Seriesensures high reliability, low expense and maximum throughput. The introduction of EFM copper bonding technology allows delivery of higher bandwidth to longer distances over multiple copper pairs, enabling a good alternative in place where fiber<br />
is not economical to deploy. This “Ethernet-pure” solution provides a seamless integration into today and tomorrow's networks.<br />
<br />
Proscend 56OOI Series extends the reach of Ethernet services to the sites by using bonded copper pairs. Up to 4 pairs can be bonded together for aggregated bandwidth over 61Mbps (TC-PAM 128). Designed with standard-based EFM technology (2BASE-TL), deployment of Ethernet services with 56OOI is quick and simple on the existing copper plant. It operates mainly in Point-to-Point connection between remote offices and enterprise headquarter, providing symmetrical high-speed connectivity that is ideal for large and small-to-medium enterprises to deliver business-class Ethernet service.<br />
<br />
With Proscend 56OOI Series, network performance is significantly enhanced by eliminating unnecessary<br />
conversion of packet formats when transiting between Ethernet (LAN) and legacy ATM network (WAN).<br />
User-friendly Ethernet also make it possible to save unnecessary truck roll costs and training costs. It leads to<br />
minimized risk bearing and quick return on investment for both service providers and enterprises.<br />
<br />
Proscend 56OOI Series operates the SHDSL link in either EFM mode or ATM<br />
mode. It is designed to deliver business class Ethernet Service under EFM mode while<br />
providing the flexibility to be compatible with the existing DSLAM infrastructure under<br />
ATM mode. The unit can be managed by different ports and applications including<br />
comprehensive command-line interface (CLI), Telnet, user-friendly GUI-based Web<br />
Browser Interface and SNMP.<br />
<br />
Proscend 56OOI Series provides future-proof features meeting Ethernet Quality of<br />
Service (QoS) and Class of Service (CoS) requirements by utilizing 802.1q VLAN<br />
capabilities, four levels of priorities, traffic flow control and rate control. This traffic<br />
management and QoS features enable service providers to offer highly profitable<br />
value-added services to a vast majority of business and institutional sites.
