The Cisco CE-MR meets important requirements for an end-to-end Ethernet Private Line application with features such as generic framing procedure (GFP), virtual concatenation (VCAT), software link capacity adjustment scheme (LCAS and SW-LCAS), link integrity, and comprehensive Ethernet and SONET statistics - including bandwidth utilization statistics and flow control. The Cisco CE-MR, with GFP and VCAT, helps service providers and enterprises maximize bandwidth utilization and promote industry-wide interoperability for Ethernet Private Line services. With LCAS, the Cisco CE-MR gives service providers the flexibility to dynamically add and remove bandwidth on Ethernet Private Line services.
