Configure Mono or Stereo Peer-to-Peer Programs in ViA

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 type of program.

•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.

•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 Load, Connect and Manage Programs.

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 or Answer 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:

•If you select Sessionless as the Session Protocol select UDP/IP +RTP for RFC-compliant IP streaming.

•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 (Via) is used to dial this connection, e.g. Primary (LAN1) or Secondary (LAN2) etc. Note: By default Any will first select LAN1 if it is available, or the Secondary (LAN2) or Tertiary (Wi-Fi) interface 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).

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

For IP connections click to configure:

•Auto Jitter Adapt and the preferred auto jitter Buffer Priority and Minimum depth and Maximum depth settings, 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 in case one IP connection fails. 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 LAN1. Select a different IP interface to achieve the maximum level of redundancy for redundant streaming, e.g. Secondary (from the secondary LAN2 port), or Tertiary, which is configured for Wi-Fi by default. Other USB1 and USB2 interfaces can also be selected. The redundant stream uses Remote Audio Port 9001 by default and the Local Audio Port allocated is Automatic. Note: Automatic indicates that the codec will arbitrarily allocate the local port value and send this information to the codec to which you are dialing.

Important Note:  Dual SmartStream PLUS redundant streaming over separate IP interfaces 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 see 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. Then, 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.

Description

1

Threshold

The percentage of lost data measured during a given time frame

2

Time Frame

The time frame against which lost data is measured

3

Keep Alive

The keep connection alive time before failing over to a backup connection; Tieline RTP pings every second to confirm connectivity

4

Automatic Resume

Select the check-box to configure fail back to a higher priority connection

5

Stable Time

The amount of time a primary connection must remain stable before attempting to fail back from the backup connection

6

Maximum Retries

The maximum number of fail back retries a codec can try before ending fail back attempts

7

Time Frame

The time frame used to measure the number of fail back retries attempted

For IP select the Session Protocol and Audio Port, then click Next to configure jitter buffer and FEC settings.

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.

For ISDN, settings are determined by ISDN module answering settings. For more details see Configuring ISDN Answering.

For POTS, settings are determined by POTS module answering settings. For more details see Configuring POTS Answering.
