We are attempting to create an STS-3c Ethernet circuit between 2 nodes that both have the E100T-12-G Ethernet cards on an OC-48 ring. We know there is the limitation of 12 total STS's that can be created on each of the E100T cards. Node A has (6) STS-1 circuits provisioned, while Node B has (5) STS-1 circuits and (1) STS-3c circuit, for a total of 8 STS's. During the circuit creation, the Ethernet card in Node A does not show up as an available card, while Node B ethernet card does show up as an available card. Oddly enough Node B has more STS's on it than Node A but for some reason Node A's card cannot be provisioned.
Why does this card not show up while trying to create an STS-3c circuit? If we change the circuit type to STS-1, then it does show up as an available card.
