Coupled with numerous interfaces and native edge-aggregation services such as Multiprotocol Label Switching (MPLS) and Quality-of-Service (QoS), the Cisco 7600 Series 1-Port Channelized OC-12/STM-4 to DS0 OSM meets aggregation site connectivity requirements. Using channelized interfaces to receive multiplexed T1/E1 and higher-speed circuits on a single pair of optical fibers, service providers and large enterprises can save dramatically on power, floor space, local-loop charges, and equipment costs.
The Cisco 7600 Series 1-Port Channelized OC-12/STM-4 to DS0 OSM can accept both clear-channel T3 traffic and multiplexed circuits from OC-3/STM-1, T3/E3, T1/E1, and DS0. Service features include support for IP and MPLS traffic, Class-Based Weighted Fair Queuing (CBWFQ), Low-Latency Queuing (LLQ), and Weighted Random Early Detection (WRED). Also included is support for hardware-enabled Multilink Point-to-Point Protocol (MLPPP), capable of up to 168 T1/E1 bundles supporting up to 12 T1/E1 links per bundle. In deployments where infrastructure protection is essential, these modules support SONET and SDH protection switching (automatic protection switching/multiplex section protection [APS/MSP]) in four-fiber configurations. With this combination of features and performance, Cisco provides a versatile electrical interface for the easy upgrade to the advanced network architectures provided by Cisco 7600 Series routers.
