The BXM-T3/E3 is a high-density ATM T3/E3 interface card that uses custom application-specific integrated circuit (ASIC) technology, for the BPX 8600 Series, to deliver the industry's most advanced and reliable ATM networking features. It supports PVCs, SVCs, S-PVCs and MPLS LVCs (label VC) and provides card redundancy protection. Its high-speed connectivity takes ATM to new levels of efficiency and scalability.The enhanced models of the BXM-T3/E3 also deliver the most advanced ATM switching and traffic management capabilities in the industry. These models extend scalability by doubling the connection density and cell buffers on selected models as well as provide future support for vc merging for large MPLS-based IP+ATM networks.
