Use the STS/VT Allocation tab to display how provisioned circuits populate the pools. Use this
information to free the bandwidth required for provisioning a circuit, if there is not enough existing capacity on any one pool for provisioning the desired circuit. The CE-MR-6 and CE-MR-10 cards have four pools, each with a maximum capacity of three STS-1s with SONET or three VC3s with SDH. All VCAT circuit members must be from the same pool. One of the four memory pools is reserved for the VT VCAT circuits, if sufficient bandwidth exists to support the STS circuits on the remaining three pools. To help prevent stranding bandwidth, provision your STS VCAT circuits first to distribute them evenly.
