Media Gateway Controller and DSP daughterboards

The MGC occupies slot 0 of a Media Gateway and supports legacy backplane interfaces
(DS30x, CEMUX). The MGC provides Gateway Controller functions, and does not function as
a Server. The system requires a separate Server to handle call processing requests.
The MGC card has two expansion slots for DSP daughterboards. A MGC card can provide a
maximum of 256 DSP ports (2x128-port DSP daughterboards).
