Nortel Networks Confidential 3 Overview How this chapter is organized This chapter is organized as follows: • “Functional description” on page 3 • “Hardware” on page 4 • “Software update maintenance loads” on page 7 • “OAM&P strategy” on page 7 • “Interfaces” on page 7 Functional description The Real-time Transport Protocol (RTP) Media Portal is an optional component of the network that performs many media-layer functions.
Nortel Networks Confidential 4 Overview Figure 1 Network Component Interoperability The clouds in the diagram represent two distinct networks. The Private Network cloud interacts with the Public Network cloud through the different edge components. The RTP Media Portal provides media-layer functionality for Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), and User Datagram Protocol (UDP) transmissions.
Nortel Networks Confidential Overview 5 An RTP Media Portal occupies a single chassis domain (side) on a CPX8216T. Therefore, a single CPX8216T can host two RTP Media Portal components (one in chassis Domain A, the other in chassis Domain B). Note: Chassis domains are not internet domains. This is just another terminology intended to identify Side A and Side B of the chassis. Other terms often used interchangeably are: Domain A and Domain B, as well as Left Domain and Right Domain.

Nortel Networks Confidential Overview 7 Software update maintenance loads Information on updating software loads for the RTP Media Portal are covered in “Upgrades” on page 13. OAM&P strategy The OAM&P strategy for the system is to manage operations from a central location. The central location for OAM&P management is in the System Management Console. From the System Management Console, you can view and perform operations on the various components in the system.
Nortel Networks Confidential 8 Overview Figure 4 RTP Media Portal interfaces Network Interfaces The Host CPU card provides the signaling and OAM data interface to/from the Private Network. Each I/O card (commonly referred to as a blade) provides a media stream interface to the Private Network and a media stream interface to the Public Network. NN10035-111 Standard MCP 1.1 FP1 (02.
Nortel Networks Confidential Overview 9 Figure 5 Signaling and OAM interface - CPV5370 Host CPU The rear transition module for the CP5370 Host Central Processing Unit (CPU) card contains the following: • COM2 port for connection to a terminal server and local monitor. • Two Ethernet ports which provide connectivity to the Private Network. The connection carries signaling and OAM data. — The Ethernet 1 port is always used to provide an active connection.
Nortel Networks Confidential 10 Overview Network interfaces on each of the Input/Output cards (MCPN765) in the RTP Media Portal provide a path for media streams to/from the Private Network and Public Network. Figure 6 MCPN765 Media stream interface NN10035-111 Standard MCP 1.1 FP1 (02.
Nortel Networks Confidential Overview 11 The RTP Media Portal uses the following input/output (I/O) cards: • MCPN765 front card • TM-PIMC-0101 rear transition module The transition module contains two, 10/100 BaseT Ethernet connections for RTP/RTCP/UDP media streams. Each pair of MCPN765 and TM-PIMC-0101 cards perform the following functions: • Provides connectivity for RTP/RTCP/UDP media streams to pass between the Private Network and the Public Network, as well as the public to public network.

Nortel Networks Confidential 13 Upgrades How this chapter is organized This chapter is organized as follows: • “OAM&P strategy” on page 13 — “RTP Media Portal software upgrade” on page 13 • “Task flows” on page 14 — “Shutdown the RTP Media Portal component” on page 14 — “Update a software load” on page 15 OAM&P strategy RTP Media Portal software upgrade This section describes the update strategy for the RTP Media Portal.
Nortel Networks Confidential 14 Upgrades reboots the Peripheral CPUs. When the RTP Media Portal recovers from the reset, it is running (UNLOCKED) with the upgraded software. Note: It is possible to update one RTP Media Portal and reboot it while the other half shelf is running the load that has not been updated. Once one half shelf is updated, the other half shelf can be locked, updated, and rebooted. Upgrading all RTP Media Portals concurrently will cause a service outage.
Nortel Networks Confidential Upgrades 15 Update a software load The following procedure describes how to update a load for the RTP Media Portal component: From the System Management Console 1 Select the RTP Media Portal Server, select Components, right-click the desired component and select Update.
Nortel Networks Confidential 16 Upgrades Figure 8 Updating the RTP Media Portal from the pull-down menu After selecting Update, the following window appears: Figure 9 The update window, retrieving the load list NN10035-111 Standard MCP 1.1 FP1 (02.

Nortel Networks Confidential 19 Fault management How this chapter is organized This chapter is organized as follows: • “Network fault management strategy” on page 19 — “Fault tolerance” on page 19 — “RTP Media Portal Alarms” on page 22 — “Logs” on page 23 Network fault management strategy The system handles network fault management through the reporting of alarms and logs. RTP Media Portal alarms and logs are viewed from the System Management Console.
Nortel Networks Confidential 20 Fault management whenever a failure condition occurs on the Active SIP Application Module. • Idle Session Detection — enables the RTP Media Portal to detect and recover media resources associated with idle media sessions. This basic capability enables the system to maintain capacity and performance in the wake of a SIP Application Module failure that causes the isolation of active media sessions.
Nortel Networks Confidential Fault management 21 Figure 12 Example of viewing alarm information Clearing an alarm From the System Management Console 1 From the System Management Console, under the RTP Portal Components folder, highlight the appropriate RTP Media Portal. 2 From the toolbar, select Tools, alarm browser. 3 An alarm table appears displaying the alarms. 4 Double click the alarm row.
Nortel Networks Confidential 22 Fault management RTP Media Portal Alarms The following section details how to clear certain alarms that affect the RTP Media Portal. RTP Media Portal alarms are discussed in further detail in the MCP System Management Console Basics. Clearing the RTP101 Alarm (Blade out of service) 1 Verify that you can log in to the blade (card) from the host. If successful, the private network connection is OK.
Nortel Networks Confidential 2 Fault management 23 If the alarm persists, the number of available ports per blade (card) and/or the number of blades (cards) in the system must be increased. To increase the number of ports or the number of blades, contact your next level of support. Clearing the RTP105 Alarm (Private Port Usage) 1 Wait for at least two audit cycles to see if the alarm is cleared automatically. An audit cycle has a duration defined by the “Idle Session Audit Period” property.

Nortel Networks Confidential 43 Security and Administration How this chapter is organized This chapter is organized as follows: • “Security strategy overview” on page 43 • “User administration” on page 45 Security strategy overview One function of the RTP Media Portal is to secure the media interface to the private network. Securing the media layer is achieved through a combination of methods at the network level and RTP Media Portal component level.
Security and Administration Nortel Networks Confidential refer to Table 2, “RTP Media Portal tab configurable properties” on page 33. As multimedia sessions are initiated, a port is chosen from the port pool associated with the selected blade. When a multimedia session completes, their associated ports are deallocated from the pool and new replacement ports are allocated to the pool.
