® PXM-1E Processor Switch Module enables the Cisco MGX 8830/B and Cisco MGX 8850/B Advanced ATM Multiservice Switch and Voice Gateway with 1.2-Gbps nonblocking standard PNNI switching capacity for cost-effective voice and data applications.
The Cisco MGX PXM-1E Processor Switch Module enables the Cisco MGX 8830/B and MGX 8850/B Advanced ATM Multiservice Switch and Voice Gateway with 1.2 Gbps non-blocking standard PNNI switching capacity for cost-effective voice and data applications. It has a functional, space, and cost-saving design that combines switch fabric, management control, and network interface ports into a single module. It shares the same management capabilities as the Cisco MGX 8800 Series Switches for proven reliability, interoperability, and manageability. Three variations of PXM-1E modules are available with interface speeds ranging from T1/E1 to OC-3/STM-1 to give flexibility in network design. The hot-swappable optical modules minimize initial cost for further capital savings.
Key Features and Benefits
• 1.2 Gbps nonlocking switching capacity: Provides cost-effective switching throughput to meet the demand of service aggregation and voice applications at the service provider's network edge. The module fully supports Hierarchical Private Network-to-Network Interface (PNNI) routing with Multiple Peer Group and mobile PNNI to allow Cisco MGX 8830 and 8850 switches to easily integrate with a large-scale PNNI network.
• Choices of interface speeds and density: The variety of Cisco MGX PXM-1E modules provides different choices of network interface speeds, interface combinations, and density to suit customer needs. Network architects can choose from the 16-port T1/E1 PXM-1E module, the 8-port OC-3/STM-1 module, or the 4-port OC-3/STM-1 and 8-port T3/E3 Combo PXM-1E module. The mix of T3/E3 and OC-3/STM-1 in a single module brings unprecedented flexibility for network connectivity.
• Individually replaceable optical modules: Offer a unique way to minimize network hardware down to the port level. This translates directly into cost savings. Add more optical modules to the 8-port OC-3/STM-1 or the Combo PXM-1E module for easy network expansion at low incremental cost.
• 1:1 redundancy and SONET/SDH Automatic Protection Switching (APS): All Cisco MGX PXM-1E module types support 1:1 redundancy to provide high availability of the switch fabric, control processor function, and network interfaces. This capability is essential for supporting mission-critical services. The optical OC-3/STM-1 interfaces also support SONET/SDH 1+1 APS for facility-failure protection. The added reliability helps service providers, government organizations, and enterprises to sustain reliable services to improve customer satisfaction and reduce support cost.
