    12. Carrier Ethernet CoS IA Phase 1 Attributes CoS ID and Color Indication at UNI and E-NNI UNI: EVC+PCP or EVC+DSCP E-NNI: EVC+PCP or EVC+PCP+DEI 3 CoS Model: CoS Label High, Medium, Low Up to 3 CoS per EVC supported Performance Objective placeholders for Frame Delay, Frame Delay Variation and Frame Loss per CoS Label and per EVC Type Objectives will be mandatory when quantified and may be different for different EVC types PCP and DSCP values for CoS ID provided for MEF CoS Mandatory at E-NNI & recommended at UNI Additional Service Provider defined CoS allowed (e.g., Mobile Backhaul Use Case with 4th CoS) 3 of 8 PCP values not used in 3 CoS Model
