With service provider-friendly hardware and mission-specific software, the Cisco ME 3400 Series is the first access switch family optimized for both the Ethernet-to-the-Home (ETTH) triple-play services and Ethernet-to-the-Business (ETTB) VPN services. It provides a complete security solution for Metro Ethernet access that includes subscriber, switch, and network protection. The Cisco ME 3400 Series supports multiple software images to provide a ' pay-as-you-grow' deployment model. With service breadth spanning triple-play and Layer 2 and Layer 3 VPN services, reduced total cost of ownership (TCO) and operating expenses (OpEx) can be achieved from a single ETTH and ETTB access solution.
