PMC Modules provide T1 and E1 interfaces Providing T1 or E1 functions in a PMC form factor, the PM/T1 and PM/E1 modules can be used with standard VME boards or an OEM`s proprietary design. Both modules feature the Motorola PowerQUICC processor configured with 4 or 8 Mbytes. The PowerPC-based communications controller has the capability to provide the T1/E1 interfaces, protocol processing, or data-manipulation applications. Currently, the modules support Wind River`s VxWorks RTOS. Future support will include ISI`s PSOS operating system.
