Next Generation “Ethernet over DSL” Solutions Specialized in Ethernet Extension of Symmetric DSL in the First Mile For Metro Ethernet Networks Business DSL Platform Selection Guide January, 2005 Next Generation Broadband Communication Systems Contents Mission Statement Deployment Records Geographical Penetration By Countries Customers Testimonials DSL Network Evolution Telecommunication Network Evolutions DSL Network Evolution Network Migration Scenario SHDSL Applications Mini-DSLAM Vendor Comparison Competitive Analysis (1) & (2) Intelligence vs. Speed Product Offerings Product Roadmap Strategic Partnership Development Next Generation Broadband Communication Systems Mission Statement To be the Leader in “Ethernet Evolution in the First Mile Solutions” for Multi-media Services To build Next Generation Broadband Access Networking solution for both service providers and enterprises. Offering more bandwidth to the customers by eliminating ATM overhead (ATM Tax – around 10% of the total throughput required for ATM packet handling) in the first mile span between DSLAM and CPE. Low CAPEX and OPEX of this infrastructure makes more affordable than 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: universal broadband access employing a single technology end-to-end and enabling limitless broadband applications and services for residential and business users.
