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 the most complete security solution for Metro Ethernet access that covers 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 + ETTB access solution.
