Media Card 32S

The Media Card 32S card (NTDW65AA) provides the following features:
•
•
•
Secure Real-time Transport Protocol
The Media Card 32S card uses Secure Real-time Transport Protocol
(SRTP) to secure the IP media path between the card and the Nortel
Phase II IP Phones, IP Phone 1110, IP Phone 1120E, IP Phone 1140E, IP
Phone 1150E, IP Phone 1210, IP Phone 1220, IP Phone 1230, another
Media Card 32S card, or a DSP daughterboard. When Media Security is
configured to On, the Call Server sends a message to the Voice Gateway
software on the Media Card 32S card to activate SRTP for the media
connection established for that call.
Media Security is configured by the system administrator.
For information about SRTP, see IP Phones Fundamentals (NN43001-368)
and System Management Reference (NN43001-600).
Processors Two separate processors on the MC 32S card are known
as the Control and Signaling Processor (CSP) and the Media Stream
Processor (MSP). The CSP runs application and signaling code, whereas
the MSP processes the media streams.
