Could you provide a little more clarity regarding the network configuration.
What 15454 SW version are you running? Which CE card do you have? What Ethernet circuits are you trying to set up?
You indicate you are receiving an OC-3c carrier circuit but mention provisioning the optical interface to support SDH (which would be an STM-1). An OC-3C circuit is a single channel which cannot be broken down into smaller circuits using VCAT. The CE-series cards are designed for point-to-point circuit over SONET/SDH. With an OC-3c circuit, only one Ethernet circuit would be supported.
Thanx!
