• TCP, Transmission Control Protocol, communicates configuration,
performance data, logs, and alarms (OAM data) between the RTP
Media Portal and the Management Module.
Network interfaces
The RTP Media Portal is comprised of two physical hardware
subcomponents: a single Host CPU, and up to six (6) Media Blades.
The following figure shows an example of RTP Media Portal
dual-network connectivity between a Protected MCS Network and a
Public Network.

The Host CPU interacts with the management infrastructure to provide
OAM capabilities. The Host CPU also provides the control capabilities
(MPCP) through which a call controller can access, manipulate, and
apply advanced functions to media streams.
The Media Blades provide the Media Packet Engine for processing
media streams. A Media Blade can be configured for a dual- (see
Figure 6 ) or single-network deployment (see Figure 7 ). For
single-network deployment, the Media Blade and Host CPU must be on
the same local network. This enables the distributed Host and Media
Blades to communicate using a non-routable network addressing
scheme.
