Bias-Free Language
The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco
® MGX
® 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.
Product Overview
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.
