... This device provides a standard-interface intelligent switching solution ideal for a variety of access/edge, metro, and core applications. Typically, the VSC874 is used on a variety of line cards where it connects directly to media access controllers (MAC), framers, and network processing units (NPU). These line cards can then be interconnected using either a low-cost mesh without a switch device (‘ ...
