The switch must be capable of being scaled up to a 102.4 gigabit per second switching capacity. The switch must include four OC-3 single-mode and eight OC-3 multi-mode ports, one per slot, each rated at 155 Mbps. Each switching node must be capable of supporting at least 94 separate slots, each capable of supporting an OC-3 multi-mode port rated at 155 Mbps. The switch must be capable of being upgraded to include fully redundant switching capabilities for network reliability. The switch must be compliant with the ATM Forum User to Network Interface Specification 3.0 (UNI Spec v3.0) for both PVCs and SVCs and provide compliancy with the Interim Local Management Interface, or ILMI portion of the UNI Spec.
