• The Cisco ONS 15454 MSPP helps enable service provider and enterprise customers to build robust, scalable, multiservice transport networks to support their metropolitan-area (metro) or regional, public, and private communication needs. The Cisco ONS 15454 is the first in its class to consolidate SONET/SDH, dense WDM (DWDM) transmission, Layer 2 and Layer 3 packet-processing functions, and storage area network (SAN) transport with the intelligence of an IP-based management plane in a single, cost-effective platform. Designed for metro and regional networks, the Cisco ONS 15454 offers a wide mixture of data, voice, and video service interfaces, efficient bandwidth aggregation, and scalable transport bandwidth from 155 Mbps (OC-3/STM-1) to 10 Gbps (OC-192/STM-64) and integrated DWDM transmission for continued network scalability.
