The Cisco OC-48c/STM 16 Layer 3 Packet-over-SONET line card is a high-capacity, high-performance interface that enables service providers and carriers to substantially increase the data load on their existing fiber networks. The product provides outstanding scalability and enables customers to aggregate an enormous amount of bandwidth in a single pipe with superior statistical multiplexing. These capabilities help eliminate the need for expensive "forklift" upgrades to existing equipment as demand for services escalates.
