components in the system and administrative access to OAM functions
(including fault and configuration management).
RTP Media Portal OAM data is stored on both the Management Module
and the database. The Management Module stores alarm and log data.
Configuration data is stored locally on the RTP Media Portal as well as
persistently in the database. For a graphical view of these relationships,
please refer to

Interfaces
Protocols
While in service, the RTP Media Portal interfaces with the network
through the following protocols:
• MPCP, Media Portal Control Protocol, used to control messages
between the SIP Application Module and the RTP Media Portal.
MPCP messages control the making, modification, and breaking of
media session connections.
• RTP, Real-time Transport Protocol, transports real-time media
streams (for example, audio and video) across a packet network.
• RTCP, Real-time Transport Control Protocol, provides a means of
sharing session data (for example, performance data) between
endpoints.
• UDP, User Datagram Protocol, provides data-based media streams
(for example, file transfer).
