Functional description

Media Cards use different types of firmware pre-installed, depending on the
application being supported. The Voice Gateway application enables Digital
Signal Processors (DSPs) for either line or trunk applications. When the
Voice Gateway application is installed on the Media Card, the card is called
the Voice Gateway Media card. Other examples of applications on a Media
Card include IP Line 3.0 and Integrated Recorded Announcer.
The NTVQ01xx Media Card connects an IP and circuit-switched device.
The DSPs perform media transcoding between IP voice packets and
circuit-switched devices. The Media Card also provides echo cancellation
and compression/decompression of voice streams.

Survivability

Refer to Communication Server 1000S: Installation and Configuration
