Gateway and Gateway 4 Manual v1.5

Important Note: The AoIP Web-GUI displays all the panel settings available within the AoIP menu in the Toolbox HTML5 Web-GUI.

Important Note: When the codec is configured for WheatNet-IP the Tieline AoIP Web-GUI in the codec is inactive because the device AoIP interface is controlled by Wheatstone's Navigator software.

Important Note: PPMs on the AoIP Destinations panel are inactive if the Digital Input Type is not set to Audio over IP and the corresponding input Type is not set as Digital.

Gateway 4

Sources and Destinations

Configure up to 4 mono, or 2 stereo, or 1 x 8 channel (with up to 4 active channels) Source/Destination stream in the Gateway 8 codec.

Gateway 8/16

Sources and Destinations

Configure up to 16 mono, or 8 stereo, or 2 x 8 channel AES67 Source/Destination streams in a Gateway 16; configure up to 8 mono, or 4 stereo, or 1 x 8 channel Source/Destination stream in the Gateway 8 codec.

Parameter

Settings

Name

Source stream name for identification purposes only; no effect on stream.

Address

Multicast IP address details; the default address for 16 source streams is 239.33.1.0 to 239.33.1.15.

UDP Port

The default UDP streaming port for RTP packets is usually 5004

Interface

Select the primary AoIP interface to use for the source stream.

Frame Size

Various settings from 125 microseconds to 4 milliseconds

Codec Type

Choose from L16 (16 bit) or L24 (24 bit) sampling; note the sampling frequency is configured in the Synchronization panel and is usually 48 kHz. All streams us a common sampling rate.

Mode

Select from 2 channel or 8 channel streaming in streams 1 and 9; this setting is not available for other streams and 2 channel is the default. Note: streams become unavailable when 8 Channel mode is selected, based on how many channels out of 8 are selected. Note: The number of channels available depends on the model of codec purchased and channel licenses installed. Between 8 and 16 channels may be available.

Type

Configure mono or stereo streams; 3 - 8 channels also available for streams 1 and 9.

Upmix

Select the Enable check-box to duplicate a mono channel for a stereo stream.

Enable Discovery

Select a discovery protocol for simplified stream connection management, e.g. SAP, NMOS and/or RAVENNA. Note: No SAP announcements are sent if PTP is not locked.

Livewire Compatible

Select the Enable check-box to fix several parameters to values compatible with Livewire Sources.

Stream Mode

Select the preferred Livewire+ Stream Mode to suit the type of Source being configured.

Time To Live (TTL)

Setting used in multicast routers to ensure data packets have a finite life and don't cause congestion over networks. Each time a packet passes through a router it reduces by 1 until it reaches zero, at which point a router will no longer pass the packet.

QoS DSCP

Quality of Service setting using the DiffServ method as described in RFC 2474. Uses the DSCP field to mark packets according to their packet class. 34 is the default setting and recommended for AES67. 46 is used for expedited forwarding.

VLAN Priority

Represents a QoS prioritization scheme for Ethernet frames.

Payload Type

Some equipment requires a payload setting and the Tieline default setting is 96

Add Redundant Stream

Add a redundant IP stream and transmit an identical IP packet stream over a different AoIP interface. Packets are seamlessly reconstructed by the receiver to ensure flawless audio is received.

Parameter

Settings

Name

Destination stream name

Address

Multicast IP address details; the default address for 16 destination streams is 239.46.1.0 to 239.46.1.15. Note: The default destination multicast address will normally be configured by the device streaming audio to the Tieline codec. Verify this address with the network IT administrator and then place the correct address into the Address text box in the Destinations panel.

Channel

The unique channel number used by Livewire to identify streams. Note: Only displayed for Livewire streams.

UDP Port

The default UDP streaming port for RTP packets is usually 5004

Interface

Select the primary AoIP interface to use for the destination stream.

Codec Type

Choose either L16 (16 bit) or L24 (24 bit) samples. All streams us a common sampling rate.

Mode

Select from 2 channel or 8 channel streaming in streams 1 and 9; this setting is not available for other streams and 2 channel is the default. Note: streams become unavailable when 8 Channel mode is selected, based on how many channels out of 8 are selected.

Type

Configure mono or stereo streams; 3 to 8 channels also available for streams 1 and 9.

Downmix

•Applies -6dB of gain reduction to left and right channels of the received 2 channel stereo stream and downmixes into mono. Note: When configuring a mono Destination stream, if a stereo RAVENNA, SAP or Livewire stream is parsed, then Downmix will be automatically selected for compatibility. RAVENNA and SAP include SDP info on the number of channels in a stream.

Enable Discovery

Select the check-box to enable NMOS discovery and configuration/control of a Destination audio stream.

Livewire Compatible

Select the check-box to Enable Livewire+ compatibility in the codec. This feature fixes some parameters to values compatible with Livewire Destinations. The Livewire tab in the Destinations panel displays all advertised Livewire+ Sources across the network.

Type

The Livewire Compatible stream Type is typically configured when a Livewire stream is parsed using the Livewire tab. It can also be manually configured using the Type drop-down menu. Options define elements like whether a specific Livewire IP address range is configured, or a custom stream configuration can also be defined.

Syntonous

Syntonous receive mode is used by default in Livewire Destinations and is supported by some other vendors. In Syntonous mode the sampling frequency is locked, but the absolute time reference at the sender and receiver may be different. Redundant streaming is not supported in this mode.

Buffer Depth

The storage buffer used to capture incoming data packets when operating in Syntonous mode. It ensures the continuity of audio streams by smoothing out packet arrival times during periods of network congestion.

Link Offset

The Link Offset is defined as the difference in time between when the audio enters the transmitter and exits the receiver. The link delay setting must be greater than the worst case link delay, taking into account network jitter. This setting is not available in Syntonous mode.

Source Filter Enable

(Advanced Settings)

Select the check-box to enable and disable Source filtering.

Source Filter Address

(Advanced Settings)

Only accept data from the origin address that is pushing to the multicast address. Leave empty to accept any source address.

ST 2110-30 Compatibility

Select the Enable check-box to configure the Media Clock Offset setting as 0. This is required for ST2110-30 compliant streaming.

Media Clock Offset

Configurable Media Clock Offset setting. Note: when ST 2110-30 Compatibility is enabled this setting is greyed out and set to 0.

Add Redundant Stream

Add a redundant IP stream and stream an identical IP packet stream over a different AoIP interface. Packets are seamlessly reconstructed by the receiver to ensure flawless audio is received.

HTTP Nodes

RAVENNA allows advertisement of web management interfaces controlling devices to which you are connecting. The HTTP Nodes tab displays Hostname and Address links to launch a device management interface directly.

Livewire

Displays available Livewire+ Sources. When a Source is selected, the SDP is fetched, parsed and populated in the fields within the Destinations panel.

Manual SDP

Copy and paste SDP text from an AES67 compatible device and click the Parse SDP button to configure a destination stream. This will configure the codec to receive an audio stream from a device.

RAVENNA tab

Displays available RAVENNA Sources. When a Source is selected, the SDP is fetched, parsed and populated in the fields within the Destinations panel.

RAVENNA URL tab

Copy a known RTSP URL address for a device and then paste into the RAVENNA URL tab to populate data in the Destinations panel.

SAP tab

Displays sources advertised using SAP. When a Source is selected, the SDP is fetched (and can be viewed), then it can be parsed and populated in the fields within the Destinations panel.
