Media Processing (MPM) Module
The Media Processing Module (MPM) is an optional, customer-ordered AMC-based module that provides additional digital signaling resources (DSP) required for transcoding call sessions. You can install up to three MPM modules. Two different MPM module types are available for purchase, according to your deployment regarding the number of required transcoding sessions:
| ■ | MPM8B module, providing 8 DSPs: |
MPM8B
| ■ | MPM12B module, providing 12 DSPs: |
MPM12B
You can install both module types in the same chassis. For maximum number of supported transcoding sessions per MPM module type, refer to the User's Manual.
For module slot assignment, see Module Slot Assignment.
| ● | MPM installation can only be done when the device is powered off. Therefore, before installing an MPM module, make sure that the device is powered off. For more information, see Installing the MPM Modules. |
| ● | The serial port and reset pinhole button are reserved for future use. Please do not use these items. |
The MPM provides LEDs for indicating various operating status, as shown in the following figure and described in the subsequent table.
