NexComm Systems is a leading provider of Ethernet access over copper solutions. The company¡¯s goal is to build next-generation broadband access networking solutions for both service providers and enterprises so that they can offer multimedia services to their customers or end users at fiber speed, integrating voice, data and video over the same existing copper infrastructure.
With more than 10 years of experience in the DSL market fields, NexComm tries to achieve the goal by implementing Ethernet in the First Mile Copper (EFMC-defined by IEEE P802.1ah EFM Task Force) as a basic access technology.
Its core products are N500 EFM (Ethernet in the First Mile) modem and N5000 MSAP (Multi Service Access Plaform).
N500 series extends the reach of Ethernet services to sites with no access to fiber by using bonded copper pairs. Designed with standard-based EFM technology (2BASE-TL), N500 series cost-effectively allows service providers and enterprises to deliver Ethernet services with symmetrical bandwidth at rates up to 22.8 Mbps. The delivery of Ethernet services with N500 can be made quickly by using existing copper plant.
N5000 is a carrier class Multi-Service Access Platform that bridges the gap between legacy and the next-generation networks. By utilizing both existing TDM and innovative Ethernet in the First Mile (EFM) technology, N5000 provides existing and forthcoming service interface over copper and fiber.

Features
Being based on the Native Ethernet technology, the existing network can be evolved into the next generation network in a very cost effective way. In addition, this Ethernet technology can make access network more scalable, meeting the requirement of today¡¯s bandwidth intensive application.

Crystal Clear Answer to the challenge for migrating from legacy to the next generation network. The availability of supporting conventional TDM service interfaces (E1/T1) in Customer Servicing Area enables service provider to aggressively face the challenge for migrating from circuit based to packet based next generation network in rapid and cost effective way.

Maximize ROI by flexibly deploying services either over copper or fiber with single platform depending on customer¡¯s situation. Without the need of operating two systems, one for fiber and one for copper media, service provider can quickly deploy Therefore,when it comes to copper,they can maximize benefit by exploiting ubiquitous existence of the copper snd timly-mannered deployment provide premium service with a big pipeline to customer.

Comprehensive and easy OAM & P functions in provisioning and managing - The N5000 implements IEEE 802.3ah standard and the vendor extended management features based on the standard. It enables users to significantly reduce OPEX by eliminating unnecessary truck roll costs and additional training costs as it is based on user-friendly Ethernet technology. N5000 is interoperable with Fast and Gigabit Ethernet interfaces from switches, routers, and NG-SONET/SDH equipment. In addition, N5000¡¯s CPE can work as a smart Ethernet Demarcation Device which is necessary for carriers to provide separation between carrier WAN and enterprise LAN by monitoring network status and operation at the customer site. N5000¡¯s management interfaces include comprehensive command-line interface (CLI), user-friendly GUI-based Web Browser Interface, SNMP and Telnet.

Future-proof Ethernet traffic management and QoS features - The N5000 provides future-proof features meeting Ethernet Quality of Service (QoS) and Class of Service (CoS) requirements by utilizing 802.1q VLAN and DSCP capabilities, stacked VLANs (Q-in-Q), 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.

NexComm Systems

NexComm Systems' ultimate goal is to build Next Generation Broadband Access Networking solutions for both service providers and enterprises.
So they can offer multimedia services to their customers or end users, at fiber speed, integrating voice, data and video over the same existing copper infrastructure, yet low CAPEX and OPEX of this infrastructure makes more affordable than fiber.
NexComm can achieve this goal by implementing Ethernet in the First Mile Copper (EFMC-defined by IEEE P802.1ah EFM Task Force) as a basic access technology. NexComm's EFMC vision is universal broadband access employing a single ethernet technology end-to-end and enabling limitless broadband applications and services for residential and business users.
