Introduction

EVO Overview

Acom EVO is technology that provides Acom console functionality for PCs distributed across a LAN or WAN. Zetron’s other type of console network uses E1 links to connect consoles with the Acom Console Unit (ACU) in the Common Control Equipment (CCE) rack. Acom EVO instead provides a native IP interface between the console and the Ethernet Interface Unit (EIU) in the rack. Each EIU supports two console groups (typically 5-10 consoles, depending on their use configuration).

Acom EVO Manager Overview

Introduction

Acom EVO Manager is used to configure several aspects of the Acom EVO coMedia Dock. Configuration includes console-specific settings, networsettings, digital IO behavior, and alarm behavior.

Acom EVO Manager can ed

nsole and k settings, audio

it a new configuration derived from factory default settings, a previously saved configuration file, or currently used settings pulled from the local or any network-connected Acom EVO console. A configuration can also be pushed from Acom EVO Manager to the local or any network-connected Acom EVO consoles. When working online with an AVC service or using Batch Update, you do not edit with the XML file directly, instead the online AVC service writes your changes to its AVC-Config.xml when you persist changes.

Interface

C

A tabbed interface provides Acom EVO Manager with the capability of editing multiple configurations at once, including a mixture of new, previously saved, and settings currently in use on a live Acom EVO console. The tabs are labeled as follows:

• A new configuration is labeled New.

• A saved configuration file is labeled with its file name.

• A configuration pulled from an Acom EVO console is labeled with that console’s AVC service IP address.

Hardware Modes

Acom EVO Manager operates in one of two hardware modes: Standard or Featured e. The mode is determined by the type of hardware being configured.

Standard Mode

mod

Acom EVO can be used with a simple analog headset connected to the computer’s Manager, this arrangement is considered

the Standard mode. In this mode, there are severe limitations to audio routing and configuration. The selection of compatible audio hardware is also greatly diminished.

Figure 1: Standard mode (Acom EVO without Media Dock)

microphone and speaker jacks. In Acom EVO

Featured Mode

When a Media Dock is connected, the console has significantly increased audio capability, it is compatible with a much larger selection of audio hardware, and it supports auxiliary IO. In Acom EVO Manager, this arrangement is considered the Featured mode. The Mode and Dock selection determine the configuration choices presented.

For more information about the Media Dock hardware, refer to its manual.

RTP Statistics

Figure 20: Diagnostics screen, RTP Statistics tab

The RTP Statistics tab shows various statistical and quality measurements concerning audio throughput from the EIU to the console via Real-time Transport Protocol (RTP). The AVC monitors transmission statistics via RTP Control Protocol (RTCP) to collect this data.

To help counter the packet delay variation (“jitter”) that can occur in IP networks, the EVO system buffers audio data packets for a brief period of time (typically about 20 milliseconds) before playing them out to the console. This allows delayed packets to be

Connecting the console to just one Ethernet switch (by using a single NIC) is not recommended because it creates a single point of failure at the Ethernet switch that can remove one or more consoles from service. To be fully redundant you must use dual NICs and two EIU interfaces.

Additional redundancy is possible at the EIU card itself. The EIU has two network interfaces and may be connected to different Ethernet switches.
