Cisco PXM1 - Control processor - 2 ports - ATM - refurbished - plug-in module
The Processor Switch Module (PXM1) provides the switching fabric in the MGX chassis. This PXM1 allows Cisco customers to scale the switch focus and capacity to 1.2 GBps (PXM1). The PXM1 combines the functions of the processor, the switch fabric, and broadband ports into a single module.The MGX supports both shared memory and cross-point switching technologies to optimize costs for narrowband requirements. Although the backplane is capable of 45 GBps, the customer can choose to deploy a 1.2 GBps-shared memory fabric (PXM1) to support the narrowband service modules. The PXM1 provides 1.2 GBps of nonblocking bandwidth.
