Configure Multi-Unicast Dialing Programs

Important Notes: Before you start program configuration please note:

•You cannot edit a program when it is currently loaded in the codec.

•You can lock a loaded custom program in a codec to ensure the currently loaded program cannot be unloaded by a codec dialing in with a different program type.

•If you are dialing to both G3 and Bridge-IT, Merlin or Genie codecs, by default the Audio Reference Level will be configured for the compatibility of the codec dialed first. I.e. if you dial a G3 codec first then the G3 Audio Reference Level will be configured for all connections.

•Connections are dial only for multi-unicast programs.

•Some drop-down menus and settings may be greyed out intentionally depending on features available.

•It is possible to save a program at several points throughout the program wizard and use default settings to save configuration time. The first connection in each multi-unicast stream determines default settings (e.g. algorithm, sample rate, bit rate), for all subsequent connections in that stream, except for dialing settings.

•All algorithms are supported for multi-unicast connections, however only one can be used for each audio stream.

•Bidirectional audio is only available on the first connection dialed.

•Forward Error Correction (FEC) is not available on multi-unicast connections.

•Renegotiation of connection bit rates is not possible when connected.

•Ensure you have sufficient connection bandwidth at the local codec to support all the connections to which you are connecting.

•SmartStream PLUS is not available for multi-unicast connections.

•If a codec is answering more than one mono or stereo multi-unicast connection it is necessary to create an answering program to suit the answering configuration and lock this program in the codec.

•To learn more about programs see the section titled About Program Dialing.

Important Note: When you decide to use an existing program as a template, the new program inherits all the settings of the template program and you can adjust these settings as required by continuing through the program wizard.

Important Note: Bidirectional auxiliary IP data is available on one audio stream when configuring 2 or 3 x Multi-Unicast dialing programs. When auxiliary data is enabled on one stream the option is greyed out for other audio streams in the program wizard. Auxiliary IP data connections are not possible between the codec and G3 Commander and i-Mix codecs over multi-unicast connections. See RS232 Data Configuration for detailed information on RS232 data and see Enabling Relays and RS232 Data for more information on relay operations.

For IP connections configure the IP address, ports, and then specify which streaming interface is used to dial this connection, e.g. Primary (port ETH1) or Secondary (port ETH2). Note: By default Any will select ETH1 if it is available and ETH2 if it is unavailable.

Click Save Program to save the program with the default algorithm, jitter and FEC settings which are physically entered in the codec. Alternatively, click Next to specify individual algorithm, jitter buffer and FEC settings (recommended).

Click the drop-down arrows on the right-hand side of each text box to adjust the Encoding, Sample rate or Bit rate options.

Click to configure:

•Auto Jitter Adapt and the preferred auto jitter setting using the drop-down arrow for Buffer priority, or

•Fixed Buffer Level and enter the Jitter Depth, which must be between 12ms and 5000ms depending on the algorithm you select.

•Local and Remote FEC settings if required.

Important Notes: For 2 x Multi-unicast and 3 x Multi-unicast programs, configure new audio streams and connections as required in the same way as the first multi-unicast audio stream.

Audio Send Port 9000 is configured by default for the first audio stream's connections. A second audio stream (2 x Multi-unicast programs and 3 x Multi-unicast programs) uses Audio Send Port 9010 by default; a third audio stream (3 x Multi-unicast programs) uses Audio Send Port 9020.
