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.

Figure 2 Card slot associations for the two logical Domains in a

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

A rear view of the CPX8216T is shown in Figure 4, Motorola chassis
