Copyright © Nortel Networks Limited 2006 8 Figure 1, Network component topology, on page 8 is a graphical depiction of the RTP Media Portal’s position in a single-network MCS solution. Figure 1 Network component topology Hardware The RTP Media Portal resides on a Motorola* CPX8216T platform, a 16-slot CompactPCI (cPCI) chassis design.
Copyright © Nortel Networks Limited 2006 9 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.
Copyright © Nortel Networks Limited 2006 10 to left (1-16). A front view of the CPX8216T is shown in Figure 3, Motorola chassis CPX8216T - front view, on page 10. Figure 3 Motorola chassis CPX8216T - front view A rear view of the CPX8216T is shown in Figure 4, Motorola chassis CPX8216T - back view, on page 11. NN10265-111 MCS 5100 3.5 Standard 4.
Copyright © Nortel Networks Limited 2006 11 Figure 4 Motorola chassis CPX8216T - back view Within the CPX8216T dual 8-slot architecture, each logical Domain in the chassis contains a dedicated host card (with an associated transition module in the rear), a slot dedicated to the Motorola Hot Swap Controller (HSC), and the remaining six slots which may be populated with Media Blades (media input/output cards with an associated transition module in the rear).
Copyright © Nortel Networks Limited 2006 12 Each logical Domain, and therefore each RTP Media Portal, consists of the following hardware components: • a single CPV5370 Intel processor board (the host card) with 1 GB memory, a SCSI input/output (I/O) daughter board, and rear Transition Module.
Copyright © Nortel Networks Limited 2006 13 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 Figure 5, OAM interoperability, on page 13.
Copyright © Nortel Networks Limited 2006 • 14 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.

Figure 9 Media stream interface – MCPN765 Media Blade to RTP Media Portal Protected MCS Network A Media Blade in the RTP Media Portal consists of the following input/output cards: • MCPN765 Front Main Board • TM-PIMC-0101 Rear Transition Module There is a 1:1 relationship between the Front Card and Rear Transition Module.
Copyright © Nortel Networks Limited 2006 18 The Rear Transition Module contains two, 10/100 BaseT Ethernet connections for RTP/RTCP/UDP media streams. Each Media Blade (pair of MCPN765 and TM-PIMC-0101 cards) performs the following functions: • Connectivity for RTP/RTCP/UDP media streams. • Address and Port Discovery (APD) for obscured media endpoints. • Relay of media packets between end points. • An array of NAT and/or NAPT functions.

Copyright © Nortel Networks Limited 2006 108 Configuring the MCPN765 I/O Card It is recommended the following procedure be completed during maintenance hours as it will require the RTP Media Portal to reboot, and be out of service for approximately 15-20 minutes. From the System Management Console 1 Expand the RTP Portal options, right-click on RTP Portal to select Shutdown. Figure 49 RTP Portal Shutdown 2 A confirmation window appears. Click on the Yes button to continue.
Copyright © Nortel Networks Limited 2006 109 If it is necessary to change the IP address, expand the RTP Portal options and right-click on RTP Portal to select Modify. From the RTP Media Portal tab to make the appropriate changes. Figure 51 RTP Media Portal tab No further action is required, and the final step in this procedure may be skipped. 4 Expand the RTP Portal options and right-click on RTP Portal to select Restart. The system will reboot.

Copyright © Nortel Networks Limited 2006 Appendix C: Basic call flows As described in Protocols on page 13, the RTP Media Portal component interfaces to the other network components using different protocols. These protocols are used to establish and manipulate media paths through the RTP Media Portal. This enables the SIP Application Module to control the media plane throughout the life of a session.
Copyright © Nortel Networks Limited 2006 112 The following sections provide some sample diagrams and descriptions of call flows to review the basic functionality of the RTP Media Portal component. Basic call without firewalls Figure 53, Basic call flow using the RTP Media Portal (unobscured endpoints), on page 112 shows the basic call flow for a client-to-client call using an RTP Media Portal without any firewall/NAPT traversal requirements.
Copyright © Nortel Networks Limited 2006 113 The following steps provide more detail about the call flow: 1. Client A initiates a SIP session to Client B by sending an Invite message to the SIP Application Module. Within the Invite message, Client A includes SDP information that identifies the called address (IP and port of B). 2. The SIP Application Module requests resources to support the half call (connection) between client B and the RTP Media Portal.
Copyright © Nortel Networks Limited 2006 Basic call with firewalls Figure 54, Basic call flow using the RTP Media Portal (with obscured endpoints), on page 114 shows the basic call flow for a client-to-client call using an RTP Media Portal with Address and Port Discovery (APD) functions enabled to facilitate firewall/NAPT traversal requirements.
Copyright © Nortel Networks Limited 2006 115 The following steps provide more detail about the call flow: 1. Client A initiates a SIP session to Client B by sending an Invite message to the SIP Application Module. Within the Invite message, Client A includes SDP information that identifies the called address (IP and port of B). The Invite passes through the firewall/NAT A. 2. The SIP Application Module requests resources to support the half call (connection) between Client B and the RTP Media Portal.
Copyright © Nortel Networks Limited 2006 116 10. Similarly, Client B sends its first media packet to address A’. The Portal discovers the media address used by Client B and completes the connection. Now that both endpoints are known, a complete media path exists through the Portal. The packet from Client B is forwarded to Client A. All subsequent packets sent by either endpoint are forwarded through the Portal to the other side of the call. 11.
