HOVCAT(High Order VCAT )是什么意思？

Virtual concatenation (VC) is a crucial tool for bridging the enterprise-carrier connectivity gap, allowing Ethernet to be transported and switched over the existing SONET/SDH infrastructure. The LOVCAT delivers the highest density solution for these SONET/SDH edge applications, including MSPPs (Multi-Service Provisioning Platforms), Add/Drop Multiplexers, and RPR (Resilient Packet Ring) equipment. Vitesse is the only company offering both low- and high-order virtual concatenation mappers at 10 Gbps.
