Tesira network infrastructure

This article describes the supported network topologies required when interfacing Tesira Servers and Expanders.

Tesira devices support the use of many Ethernet network-based features to facilitate integrating Audio in an AV environment. Depending on the Tesira hardware, network port functions are separate or combined.

  • Tesira SERVER and SERVER IO devices have dedicated Control network and AVB network ports available on separate card modules

  • TesiraFORTE AVB devices have dedicated Control network and AVB network ports

  • Tesira Expanders use one Ethernet port and the control and AVB traffic is combined.

Overview

A Tesira system will support the following communication and audio protocols:

  • Control Network Interface – Ethernet network used to relay configuration data between Server and expander class Tesira devices and connected control computers.

  • Audio-Video Bridging (AVB) Interface – Server and Expander class devices are able to share audio using AVB capable bridges (switches). Tesira SERVER and SERVER IO devices require the use of the AVB-1 card. Expander class devices support AVB functionality natively.

  • CobraNet – Tesira SERVER or SERVER IO devices using SCM-1 cards are able to share 32 x 32 channels of audio between any other CobraNet enabled devices.

  • Dante - Tesira SERVER or SERVER IO devices using DAN-1 cards are able to share 64 x 64 channels of audio between any other CobraNet enabled devices.

  • Telephony Interfaces –

    • Server I/O devices allow up to 6 telephony cards in any combination per device:

      • VoIP – Server class devices are able to make use of the SVC-2 card and act as a SIP end point for Voice over IP functionality. 2 VoIP lines with up to 6 call instances per line are supported.
      • POTS – Server class devices are able to make use of the STC-2 card and act as a Telephone Interface to an Analogue telephone line. 2 POTS lines are supported per card.

    • TesiraFORTE VI devices make use 2 VoIP lines with up to 6 call instances per line per device

    • TesiraFORTE TI devices make use of a single POTS line per device

Wiring topologies

Single Switch

Two Servers

Two Servers can be connected directly via their AVB ports, without the need for an AVB switch, using a straight-through CAT-5e cable. This applies to TesiraFORTE as well. The Control Network will require a switch to facilitate the use of a configuration PC and Control system. The Control Computer can be removed once the Tesira devices have their configuration loaded. The example below shows two Tesira Servers with an IP switch and AVB Link

Multiple Servers and Expanders

When using more than two Servers, or a mix of Servers and Expanders, the use of an AVB Bridge (Switch) is required. The network topology allows the use of one AVB switch, interfacing all Tesira control and AVB connections to it. Alternatively there is also the ability to use a separate non-AVB switch for the control network so long as there is a link between the Control and AVB switches. The link allows control network data to be passed to the AVB network for Biamp's Expander class devices (which have only an AVB port).

Telephony and CobraNet

Tesira systems may use CobraNet interfaces for legacy devices, or telephone connections for conferencing applications.
