TesiraCONNECT TC-5D

tesiraconnect-crop.pngThe TesiraCONNECT TC-5D is a 5-port AVB-capable PoE network device which can be configured as a Dante or AVB interface to a Tesira system. While it retains all of the features of the original the TesiraCONNECT, the TC-5D also provides the ability to bridge AVB and Dante media networks. This enables easy integration of Dante devices to a Tesira AVB-only system or Tesira AVB devices ( Eg. Tesira Amplifiers,Tesira Expanders) to a Tesira DANTE-only system.

In the Tesira software, the TC-5D appears as a Tesira infrastructure device. The TC-5D works out of the box with Biamp products as a AVB network switch just like the TesiraCONNECT TC-5, and does not require any configuration. To be used as a media bridge between Dante and Tesira AVB networks, the TC-5D needs to be included in the Tesira layout. Once configured it is assigned a Unit ID and included in the equipment table.

Capabilities and limits

TesiraCONNECT TC-5D is a Switch as well as an Endpoint device that runs Tesira Firmware 3.16 or later. The TC-5D will continue to pass other network traffic even if its configured as a Dante or AVB interface. All configuration, firmware updates, and fault monitoring are provided via Tesira Software and Biamp Sagevue

The TC-5D does not support user configurable DSP, and therefore blocks like meters and level controls cannot be assigned to it in the software. The features and capabilities of the TC-5D include:

  • 5-ports with 100/1000M Ethernet
  • All 5 ports are AVB/Dante enabled, and will autodetect port role (AVB, Dante, Dante+AVB)
  • Network I/O when acting as a media bridge:
    • Dante: 32x32 channels, 32 Flows with 32 Con/Mon channels 
    • AVB: 128x128 channels and 64 Streams
    • AES67 Capable via Dante
  • All 5 ports pass control traffic
  • 4 ports provide PoE+ Class 4 with 120W PoE budget for the switch
  • RSTP (rapid spanning tree) Support
  • IGMP Snooping Support
  • Supported topology is up to 4 TesiraCONNECT devices in a single media network cluster 
  • Standard Ethernet distance limits using Cat 5e UTP or better 
  • Universal external power supply
  • Only Biamp AVB Devices supported in media bridge mode
  • Parlé Mics not supported in media bridge mode.

Larger topologies, TesiraLUX video streaming, third-party AVB devices, and mixed AV protocol networks require the use of Avnu-certified interoperable switches. Please see the List of AVB-capable Ethernet switches for further information.

System deployment examples with TC-5D 

When used as a media bridge in a Tesira system, the TC-5D can be configured in two modes:

  • Connecting Dante Devices to an AVB-only Tesira System
  • Connecting Biamp AVB devices to a Dante-only Tesira System

Connecting Dante devices to an AVB-only Tesira system

Dante devices can be integrated to a Tesira AVB system with a TC-5D acting as a AVB to Dante media bridge.

Dante blocks can now be added to a Tesira AVB only configuration file. On compiling, the Tesira compiler will automatically add a TC-5D device to the equipment table and allocate the Dante blocks to it.

In this example, the 2-channel Dante receive block is assigned to the TC-5D (Unit 2) which converts and transmits the audio channels to the TesiraFORTÉ AVB VT4 (Unit 1) as an implicit AVB stream.

The TC-5D Dante interface supports Con-Mon channels, and will support control of Tesira supported Dante devices. 

Tesira AVB system on a Dante distribution network

Tesira AVB Systems can be integrated with a larger Dante cloud or network with the TC-5D as a media bridge. The Dante network integration into the system will work the same way as adding a Dante device. All Dante routing will be handled by a Dante Controller used to configure the Dante network.

Connecting Biamp AVB devices to a Dante-only Tesira System

Tesira AVB devices such as the Tesira AMP-450P, EX-UBT or Tesira Servers can be integrated to a Tesira Dante system via the TC-5D.

Note: Parlé Mics cannot be integrated to a Tesira Dante system due to additional back-channel communications requirements only supported on AVB enabled Tesira server-class devices. 

Tesira AVB device blocks can be added to a Dante-only Tesira configuration file via pairs of Dante Input and Output blocks. On compiling, the Tesira compiler will automatically add a TC-5D device to the system. 

Tesira AVB and TesiraFORTÉ DAN Configuration.png

Compile results with Dante block added to an AVB-only layout:

In this example, a Tesira EX-UBT (Unit 3)  and an AMP-450P (Unit 4) Tesira amplifier are connected to a Dante-only layout with a TesiraFORTÉ DAN VT (Unit 1) using pairs of Dante receive and transmit blocks. 

Note: Mute Sync via EX-UBT will function as expected on Tesira Dante systems. 

The TC-5D (Unit 2) receives and transmits AVB streams from and to the expanders and amplifier. It translates Dante-AVB in both directions via the Dante Input-Output pairs added for each AVB device. 

Note: Dante Input-Output pairs have to be linked in the Dante Controller software for this integration to work. 

For building a new Tesira configuration file with AVB devices on a Tesira Dante system, please refer to this article.

Installation

The TC-5D may be mounted under table with the optional mounting bracket, behind a display, in a credenza, a plenum space, or anywhere that it is convenient to accommodate a room design. 

The TC-5D uses a fanless design and is passively cooled. Ensure adequate airflow around the device and that the ambient temperature remains between 0°C to 40°C. Excessive ambient air temperature or blocked airflow may result in overheating. The TC-5D will provide fault alerts if over temperature.

Wiring topologies

Up to four TesiraCONNECT TC-5 and/or TC-5D devices can be used within a single media network cluster. The devices may be in a star or chain topology and can be a combination of TC-5 and TC-5D devices. 

All 5 ports of the TC-5D are AVB and Dante enabled. Ports 2-5 provide PoE+ power. The DSP should be connected to Port 1. Any powered expander devices, additional server-class devices, or additional TC-5D devices should be connected to ports 2-5.

We refer to two use cases for the TC-5D as "media bridge mode" or "plain switch mode". The modes are a byproduct of system file design and do not require an additional step to activate the "mode" in the switch. A TC-5D which compiles a Dante or AVB IO block as part of a Tesira file is automatically in "media bridge mode" while all other cases are "plain switch mode". 

  • In the media bridge mode, the TC-5D is intended to connect to the AVB or Dante port of a DSP and provide connectivity for Tesira expander or Dante devices in a room. In media bridge mode TC-5D hosts AVB or Dante IO blocks and is listed in the Equipment Table of a Tesira configuration file. 
  • In plain switch mode, The TC-5D is intended to connect to the AVB port of a DSP and provide connectivity for Tesira expander devices in a room. In plain switch mode the TC-5D is a passive standalone AVB network device, not a compiled component of any Tesira DSP file. 

In both cases, Tesira supported network topologies must be observed.

Example daisy chain topology connection for a Tesira Dante system:

Tesira single cable mode topology with TC-5D (Tesira AVB systems only)

Tesira single cable mode is supported only on the AVB port, and is not available using Server-IO DAN-1 or TesiraForte DAN. 

Tesira Server-class devices with discrete control and AVB ports support Tesira "single cable mode" connections (internally converging both control and AVB media onto the AVB port). Multiple Tesira DSPs may be connected via their AVB ports to TC-5D using single cable mode. Single network connection supported topologies must be followed.

To allow a computer to discover and connect to the system via Tesira software, the PC must be directly attached to the TC-5D (or the extended AVB-control network if multiple switches are in use) when using single network connection on Tesira AVB hardware.

TC-5D does not support mixing separated and single cable connections within the same system, and it does not provide router functions between isolated control and media networks.

Converged Networks topology with TC-5D (AVB and Dante)

In converged network mode the Tesira control and AVB networks must use different logical network address ranges (e.g. - control is getting a 172.30.10.xxx address via DHCP and AVB is getting 169.254.xxx.yyy link local addressing) for TC-5D and expander discovery to work.

A TC-5D used in "plain switch mode" will support converged AVB and Control networks topology as referenced in this article. 

In "media bridge mode", the TC-5D requires converged AVB and Control networks topology (or Tesira single cable mode topology) as it participates in the Tesira configuration and hosts AVB/Dante blocks in the Tesira system. In media bridge mode the TC-5D must be visible to the Tesira control network for programming and control of the hosted IO blocks, to the AVB network for AVB streams, and to the Dante network for Dante channel routing.

Separated Networks topology with TC-5D (AVB only)

TC-5D does not provide router functions between isolated control and media networks.

A TC-5D used in "plain switch mode" for AVB in a separated network is not discoverable from the control network. A connection to the AVB network would be required to discover and communicate with the TC-5D. AVB will function properly but the TC-5D will not be discoverable for updates or monitoring from the control network.

When used in "media bridge mode", the TC-5D does not support the Separated AVB and Control networks topology referenced in this article. 

Device settings

When used in plain switch mode, the TesiraCONNECT TC-5D requires no configuration out of the box to power Biamp conferencing equipment. In this mode, the TC-5D does not compile into in a system configuration and does not require any Equipment Table assignment. It does not count against Tesira system device limits or expander proxy limits. Like any Tesira device, all configuration of TesiraCONNECT TC-5D is managed via Tesira software and Biamp SageVue software. 

Device discovery

The TC-5D device is discoverable in the Device Maintenance window of Tesira Software. Configuration and firmware updates for the device are performed from this window.

TC-5D Device Maintenance Dialog.png

When used as a media bridge, the TC-5D device should be part of the Control network. If participating Tesira Servers are configured in seperated network mode (Control port is seperated from media network), the TC-5D may show faults and may not function as expected. 

Network settings

The network settings are accessed via the Device Maintenance window. TC-5D offers similar network settings as any other Tesira server-class device with options for both AVB and Dante settings, and these additional Services

  • Enable RSTP
  • Enable IGMP

TC-5D Network Settings.png

The hostname, network addressing and device services are modified on the Control Network tab.  

By default, RSTP is enabled and the control IP address is obtained automatically. The Tesira media network generally will run without a DHCP server and default to a link local IP address. 

Telnet and SSH are provided for TTP (Tesira Text Protocol) and are disabled by default. 

The AVB tab provides the peer delay setting. The value should be increased if using fiber media convertors because they add more latency to the link. 

The Dante tab allows setting the hostname, DNS and IP configuration of the Dante interface.

Firmware update

TesiraCONNECT TC-5D is part of the Tesira platform and is updated using Tesira Firmware TFA2 files. Tesira firmware version 3.16 or newer is required.  

CONNECTFirmwareUpdate.png

All Tesira devices may be updated at the same time as the TC-5D. When a TesiraConnect (TC-5/TC-5D) device and Tesira server-class device are both selected, the TesiraCONNECT devices are updated first. The update progress window will display "Pending" on the DSP until the TesiraCONNECT devices have finished. 

Locate devices

The TC-5D supports the Locate function. All LEDs on the front of panel of the TC-5D will flash green when locate is active. The network port LEDs do not flash for locate.
