The Cisco ME 3600X Series of Ethernet Access Switches is Cisco's first series of switches built specifically for the convergence of wireless and wire-line services. A natural evolution to Cisco's Carrier Ethernet portfolio, the Cisco ME 3600X Series extends the portfolio's transport speed to 10 Gbps in the access layer for business and mobile applications. It also enables service providers to initiate Multiprotocol Label Switching (MPLS) -based VPN services from within the access layer. Designed around key Carrier Ethernet features that simplify network operation, the Cisco ME 3600X Series enables premium services with enhanced service-level agreement (SLA) capabilities. An optional "pay-as-you-grow" feature and service activation model gives service providers a flexible, cost-effective solution.
