Functional description
The Real-time Transport Protocol (RTP) Media Portal is an optional
component that addresses media plane specific issues with advanced
service delivery, Internet addressing efficiencies, and system security.
The primary function of the RTP Media Portal is to extend the reach of
multimedia services so that they are accessible to obscured endpoints,
devices residing behind a firewall, or a Network Address Translation
(NAT) and/or Network Address Port Translation (NAPT) device.
Functioning as a media NAPT point that shields Multimedia
Communications Platform (MCP) Service Network components from
external exposure, the RTP Media Portal also provides IP address/port
pair mapping between internal and external network components as
well as media anchoring and media pivot abilities for terminals.
The RTP Media Portal may be deployed in a single- or dual-network
configuration. For dual-networks, the RTP Media Portal enables
elements in the Protected MCS Network to safely communicate with
elements in the Managed IP access network.

Hardware
The RTP Media Portal resides on a Motorola* CPX8216T platform, a
16-slot CompactPCI (cPCI) chassis design.
The chassis offers a High Availability platform that provides the basic
operating environment (such as power, backplane, cooling, and
mounting slots) required to sustain the resident subcomponent
single-board computers. The CPX8216T hardware architecture
partitions the chassis into separate logical operational Domains,

dividing the chassis shelf into two half-shelves consisting of 8-slots
each.
Note: The chassis logical Domains are not internet Domains.
Rather, the term is used to identify Side A and Side B of the chassis.
Other terms used interchangeably include: Domain A and Domain B,
Left Domain and Right Domain, and half-shelf.
An RTP Media Portal occupies a single logical operational Domain in
the CPX8216T. A single CPX8216T chassis can host two RTP Media
Portal components (one in chassis Domain A, the other in chassis
Domain B) as shown in Figure 2, Card slot associations for the two
logical Domains in a single chassis, on page 9.

single chassis
If the chassis is viewed from the front, the slots are numbered from left
to right (1-16). If viewed from the rear, the slots are numbered from right
Domain A Domain B
