Configuring 2 or 3 Stereo Peer-to-Peer Dialing Programs

Important Notes: In most situations you need to create a dial only program in your Genie Distribution codec. A compatible codec receiving the call will answer using a default program.  There is no requirement to create an answering program, however if you require file playback on the answering codec it will be necessary to create an answering program which integrates this feature as explained in Configure Mono or Stereo Peer-to-Peer Programs.

Important Notes: Before you start program configuration please note:

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

•Session port 9002 is used by default for all audio streams. If you connect to a G3 codec using IP2 you will need to change the session port on the Genie Distribution codec to 9012 for the second audio stream connection, as this is used by default on G3 codecs for IP2.

•Some drop-down menus and settings may be greyed out intentionally depending on features available and the transport selected (e.g. IP or ISDN).

•It is possible to save a program at several points throughout the program wizard and use default settings to save configuration time.

•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.

•Failover and SmartStream PLUS redundant streaming are not available with SIP or sessionless IP connections.

•POTS is not supported for stereo audio stream connections.

•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.

It is also possible to select a Dial Route if required. When routing multiple audio streams over transports like ISDN or POTS, you can use Dial and Answer Routes to configure deterministic routing of audio streams. Use of Dial and Answer Routes is not recommended over IP. See Configuring ISDN Answering or Configuring POTS Answering for more information. Use the default settings for IP connections.

Important Note: Bidirectional auxiliary IP data is available on one audio stream. When auxiliary data is enabled on one stream the option is greyed out for the other audio streams in the program wizard. 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 and configure a backup connection or SmartStream PLUS for this audio stream (recommended).

Note: Session Port 9002 and Send Audio Port 9000 are used by default for the first IP audio stream. The audio for this audio steam will use analog or digital inputs and outputs 1 and 2 for both the dialing and answering codecs. If you need to change default port settings on the codec from which the call originates, this will also need to be adjusted in the answering codec.

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.

Click the check-box to select Enable Redundant SmartStream PLUS and configure dual Ethernet SmartStream IP streaming. Alternatively, click Next to configure Auto Reconnect or a backup connection, whereby the alternative connection is dialed if the primary connection fails.

By default, primary IP streaming is via ETH1. To achieve the maximum level of redundancy select Secondary to configure redundant streaming from the secondary IP port ETH2. The redundant stream uses Send Audio Port 9001 by default and the Return Audio Port allocated is Automatic. Note: Automatic indicates that the codec will arbitrarily allocate the return port value and send this information to the codec to which you are dialing.

Important Note:  Dual SmartStream PLUS redundant streaming over both Ethernet ports mitigates lost packets on either link and will provide IP network backup if an IP link is lost. To learn more about SmartStream PLUS redundant IP streaming visit http://www.tieline.com/Transports/SmartStream-IP

For ISDN connections enter a number and select which B channel to use. Select the Enable bonded connections check-box to configure and bond multiple B channels.

Next, click Save Program to save the program with default algorithm settings, or click Next to specify a different algorithm and configure a backup connection if required. (recommended).

Dialing settings for this ISDN audio stream are now complete.

Select POTS Codec in the Mode drop-down menu to encode/decode using POTS, or select Analog Phone to configure a standard analog phone call, then click Next.

Next, enter the phone number of the codec or device you want to dial. When multiple POTS modules are installed, click the Via drop-down menu and select Module 1 or Module 2 to specify which POTS module will dial. Next, click Save Program to save the program with default settings, or click Next to specify algorithm settings and configure a backup connection if required (recommended).

Dialing settings for this POTS audio stream are now complete.

Important Note: When Auto Reconnect is enabled, the dialing codec will continue to attempt a connection with the remote codec until Disconnect is pressed either on the dialing codec's keypad, or in the Web-GUI.

Important Notes for File Playback:

•Ensure MP3 recordings used are not variable bit rate files.

•File playback audio is sent directly to the codec outputs and therefore IGC is not available. When you create your MP2 or MP3 files ensure the audio levels match the audio reference level of your codec and that peaks average at the correct levels.

•USB backup audio is only sent to the outputs of the local codec to which a USB drive is attached. USB file audio is not sent to encoders and cannot be transmitted via an audio stream to another codec.

•The USB drive can be inserted or removed at any time as long as the codec is not already playing audio in failover mode.  Removing the USB drive while audio is playing from it will result in poor audio quality and should be avoided. If it is removed accidentally you must reboot the codec to ensure USB failover will work in future.

•If you enter a single file name ensure you add the file extension, e.g. "test.mp3", or the file will not play back.

•If you enter a directory name, all the files within the directory will be played back. We recommend you save all audio files as a playlist and link to this if you want them to play out sequentially. Please note that "M3U" is the playlist file format supported by the codec.

•File playback will occur automatically if the silence threshold parameters are breached; if the codec is not connected for any reason file playback will commence. To stop file playback open the Master panel in the Java Toolbox Web-GUI, click to select the file playback connection, then click Disconnect.
