MAS installation This chapter explains MAS installation fundamentals. For step-by-step information about how to install the MAS platform, see Nortel Media Application Server 6.0 for AS 5300 Installation (NN44470-300).
-8MAS installation Supported hardware platform You can install the MAS software on an IBM X3550. The X3550 has an Intel XEON 5140 2.33 GHZ processor, 2 GB of RAM and a SCSI hard drive. Supported operating system You can install the MAS software on Windows 2003 operating system (OS).
-9MAS installation and manages all platform resources. The SC is a client with respect to all other components. The SC connects to all components identified as part of one virtual system. IVR media processor (IVRMP) The IVR media processor IVRMP provides audio and video streaming, digit collection, automatic speech recognition (ASR) and Text-to-Speech (TTS) capabilities.
- 10 MAS installation Uninstallation Under normal circumstances, you need not uninstall the MAS platform unless you want to perform a clean installation. Before you install the platform, you must uninstall all applications and close all instances of the Nortel MAS Console. If instances of the Nortel MAS Console are running when you uninstall the MAS platform, you must restart the server. Reinstallation If you need to reinstall the MAS platform, you can use the MAS installation DVD.
- 11 MAS installation Music On Hold With the Music On Hold application, a system administrator can provision the MAS system to play music while a caller is hold. The Music on hold application lets a caller know that the call is still connected. It is possible to implement the Music on Hold application for the following types of hold: end-user, transfer, and Call park. This application continuously plays for the user on hold and does not restart the tune each time a user is put on hold.
- 12 MAS installation Dedicated deployment In a dedicated deployment scenario, each application is deployed on its own MAS pair to the maximum capacity of that single application. However, for the most efficient use of resources, a combination of dedicated deployment and multi application deployment is required. Co-resident deployment In a co-resident deployment, up to five MAS applications (Meet-Me, Ad Hoc, Music on Hold, Announcements, and Unified Communications) can be deployed on the same MAS duplex.
MAS commissioning This chapter describes the items that you can configure on the MAS platform. For detailed information, see Nortel Media Application Server Commissioning (NN44470-301).
- 14 MAS commissioning To view installed packaged applications, use the Nortel MAS Console. The Nortel MAS Console lists the application version and the current operational state for that application. An example of a packaged application would be Recorder. Configuration data Each packaged application has one or more configuration parameters that you can modify to alter the behavior of the application. To view and modify these application-specific parameters, use the Nortel MAS Console.
- 15 MAS commissioning • N-way—a cluster consisting of three or more MAS nodes Because the cluster is based on system replication, you must configure the same applications on all of the MAS servers in the same cluster and provision any application data (such as subscriber information) for that cluster. The SIP proxy must support load balancing across multiple MAS nodes in the same cluster.
- 16 MAS commissioning CStore N-way cluster configuration Controller Peer Ring Applications use the Controller Peer Ring to send and receive events to the various MAS nodes in the cluster. Configuration of the Controller Peer Ring depends on the number of nodes in the cluster and if the provisioned applications use the Controller Peer Ring. To create the ring, configure each MAS node with a primary and backup controller peer.
- 17 MAS commissioning 4-Way controller ring SIP signaling SIP configuration is broken into the following categories: General, Domains, Accounts, Trusted Nodes, and Routes. The following sections describe these categories in more detail. SIP properties You can modify the following SIP properties.
- 18 MAS commissioning The platform has an internal domain called the wildcard domain, which is represented with an asterisk and is the default domain if no matching domain is found. SIP accounts SIP accounts are used for application registration in the SIP network. The MAS registers all accounts against the registrar servers. For information about the servers, see SIP registrar servers (page 19). You can view, add, and delete SIP accounts.
- 19 MAS commissioning SIP registrar servers A SIP registrar server is a database that contains the location of all user agents within a domain. MAS registers its applications with all configured SIP registrars. Registration is optional based on MAS configuration. Digest authentication is supported. Media conferencing MAS supports multimedia conferencing for both audio and video streams. You can use one of the following conferencing algorithms: basic and premium.
- 20 MAS commissioning Mixing different codecs The system can mix participants with potentially different codecs in the same conference. To achieve this, the system transcodes the incoming streams into a common format, mixes, and then provides each participant with the correctly mixed audio. The system optimizes for multiple participants by transcoding the resulting mixed audio based upon a grouping of conference participants.
- 21 MAS commissioning Media settings This section describes audio codecs, video codecs, and digital relay. Audio codecs To configure audio codec settings, use the Nortel MAS Console. You can complete the following configuration tasks for audio codecs: • Enable or disable audio codecs. The following audio codecs are supported: — G.711-ULAW — G.711-ALAW — G.
- 22 MAS commissioning — RFC2833 Attention: If you remove all methods, inband DTMF detection is forced, which is not recommended because it degrades system capacity. • Configure the preferred order of enabled DTMF relay methods for negotiation (SDP answer) or default SDP (SDP offer). • Configure the RFC2833 payload type. Nortel recommends that you select the default payload type, which is determined dynamically. However, some clients require a fixed payload type.
- 23 MAS commissioning MAS uses flow specifications for each codec to identify packet delivery characteristics to the operating system, enabling it to prioritize (internally) packets destined to and from the network interface card (NIC). The framework ensures that QoS marked packets sent from MAS media processors are not dropped or delayed in their delivery to the wire. MAS can reserve a percentage of NIC bandwidth for its media processors.
- 24 MAS commissioning Continuous streaming The MAS platform supports continuous streaming of pretranscoded real-time audio that applications can use to facilitate a radio broadcast effect. With this feature, applications can give sessions music-on-hold streaming or connect the sessions to Internet-streaming radio servers. Multiple sessions can listen to the same real-time audio stream without the cost of transcoding the stream on each session or connecting each session to a remote server.
- 25 MAS commissioning RSS 2.0 sample document To enable the RSS provider, you must configure the URL of the RSS document. This document is fetched when you start the MAS platform or change the URL. The RSS provider automatically adds or deletes content when you change the URL. To configure the URL, use the Nortel MAS Console. Nortel Media Application Server 6.0 for AS 5300 Fundamentals NN44470-100 01.01 Standard Release 6.
MAS administration and security This chapter describes the administration tasks and security tools associated with MAS operation and management.
- 27 MAS administration and security User accounts This section introduces the concept of multiple users and user roles. To accommodate customers who wish to use the shared account methodology, support for the use of the shared administrator account is provided. When a user is added to the system, it is defined as filling one of these user roles assumes the ability to perform the administrative functions associated with that role.
- 28 MAS administration and security Application Administrator (AA) The Application Administrator (AA) performs administrative functions that relate to the operation of applications on the MAS system, and can perform all operations within the MAS Console. The Application Administrator can install MAS software patches, but cannot access Event Viewer Security Logs. Logon banners A logon banner is a message screen that is displayed to users before a logon to the system is attempted.
- 29 MAS administration and security • RDP is separated from other traffic by using a virtual local area network (VLAN). A VLAN is added through the Broadcom Advanced Control Suite. A virtual adapter is created for each VLAN added. The VLAN for RDP is identified as the Management VLAN. The VLAN for all other network traffic is identified as the Service VLAN. • The only protocol assigned to the Mgmt VLAN in this release is RDP.
- 30 MAS administration and security The default scheduled time for a scan to run is on Sundays at 4:22 AM. A script is provided to allow the configuration of a different day and time for when the scan is executed, or to disable automatic scanning entirely if this is desired. Scanning the entire file system (excluding configured system directories) takes at least 20 minutes under no load. This should be taken into account when determining the day and time when the scanner is to be run.
- 31 MAS administration and security To create and install a valid certificate, you must do the following: • Generate a public and private key pair. • Generate a Certificate Signing Request (CSR). • Send CSR to CA to request the certificate. • Transfer CA-signed certificate to the MAS using SFTP. • Install the certificate using the MAS Console. A certificate may also be revoked by the CA. A Certificate Revocation List (CRL) must be obtained from the CA and installed on the server.
- 32 MAS administration and security Backup of configuration data You can back up configuration data while the system is online, but the MAS must be offline before you can perform a restore operation.
- 33 MAS administration and security System maintenance It is good practice to perform routine maintenance tasks to avoid problems that can affect server performance or cause the server to fail. The MAS platform includes a number of useful tools and indicators to help you monitor your server performance quickly and easily. With these tools, you can perform regular maintenance routines.
MAS performance management Performance management includes report generation and Operational Measurements. For detailed information about MAS performance management, see Media Application Server 6.0 for AS 5300 Performance Management (NN44470-701).
