USB NENAJACK BOX CONFIGURATION
GUIDE
Introduction
NOTE
This guide is for the Avtec USBNENAJack Box operating on the Software Media Workstation. For information
regarding the Hardware Media Workstation, see the NENA/Deskset for Hardware Media Workstation
Configuration Guide.
This document explains the setup, configuration, and use of the USB NENA Jack Box.
For Scout consoles running the Software Media Workstation, Avtec USBjack boxes provide a means of interfacing
peripheral accessories, such as headsets and handsets, to Scout consoles. Administrators can adjust audio levels,
external audio interfaces, and other settings to optimize dispatcher audio.
Up to four USB jack boxes and one external audio interface (EAI) can connect to a Scout console, which allows
supervisors to join a dispatcher's call, to accommodate multiple dispatcher trainees, or to provide redundancy in the
event of jack box failure.

This endpoint is considered a "media workstation endpoint" and not a "VPGate endpoint" because the
interface is directly connected to the console through a USBcable, and not through a VPGate. The Name
you assign to this endpoint should be unique from other VPGate endpoints that are on the same domain.

Operating the USB NENAJack Box
Rules of Operation
Avtec USB NENA Jack Boxes operate according to these rules:
lScout supports configuring up to four USB jack boxes and only one external audio interface per console position.
lDue to USB host controller limitations, when plugging in your USB peripheral devices, limit the number of jack
boxes to one jack box per physical PC port. If using a USB hub connected to the PC port, there can only be one
jack box plugged into the hub.
lWhen connecting multiple USBNENAjack boxes at a Scout console position, only one jack box can be
configured to enable external audio interface.
lWhen a dispatcher answers a 911 call, the dispatcher's endpoint for the NENA device selects automatically.
oAn endpoint for the NENA device displays on the screen.
oThe call becomes active.
lWhen a dispatcher answers a 911 call via the ResourcePro Tool on a console interfaced with the USBNENAJack
Box, the call does not switch to a screen with the NENAlinepad. However, the call is automatically answered
and becomes the dispatcher's active call.
lDeselecting the NENA endpoint does not end a 911 call. A 911 call only ends when:
oThe dispatcher hangs up via the NENA device.
oThe dialing party hangs up.

Audio Tuning for NENADevices
Audio volume and quality can be adjusted in many different ways when the Avtec USB NENA Jack Box interfaces with
Scout. These options consist of physical settings and settings on the Avtec USB External Audio Interface webpage.
Physical Settings
lJack Box Volume Knob – The volume knob located on the front of the Avtec USBNENAJack Box
lNENAVolume – The physical volume settings on the NENA device
NOTES
lAvtec recommends beginning by tuning the Jack Box Volume Knob and Phone Speaker Volume to
50%.
lIf audio quality is poor after configuring the NENAinterface, ensure that audio levels at the physical
RJ45 NENAconnector meet NENAspecifications.
External Audio Interface Settings
To configure the following fields, access Devices >Peripherals on the Console Configuration webpage, and then select
the External Audio Interface for the jack box.
lWindows Input Level (%) – The level of audio sent from the NENAphone to the Software Media Workstation
console
lMic Gain (dB) – The input level, as a percentage, of the Windows Microphone level that this external audio
interface should use
lOutput Level – The level at which the Software Media Workstation console outputs audio to the external audio
interface of the jack box (NENA device)
VAGCSettings
Voice Automatic Gain Control (VAGC) settings for Avtec USBperipherals enhance audio clarity for dispatchers.
Introduced in Scout Version 4.13, these settings allow administrators to adjust VAGC target, loss/gain, and threshold
settings to account for elevated background noise, variances in individual dispatcher audio, and other scenarios.
VAGCadjustments to transmit (outbound) audio are made on the Avtec USBJack Box webpage. VAGCadjustments to
receive (inbound) audio are made on the Avtec USBExternal Audio Interface webpage. These VAGCsettings include
the following:
lVAGC – Determines whether the Voice Automatic Gain Control adjusts the level of voice audio entering the
device from the field.
lVAGC Low Target (dB) – Sets the VAGC Low target for this device. When the input signal exceeds the
VAGCThreshold, the VAGC alters the receive audio so that it remains between the VAGC Low Target and VAGC
High Target.

Phone: [phone] • Fax: [phone]
100 Innovation Place • Lexington SC 29072 USA

lVAGCHigh Target (dB) – Sets the VAGC High Target for this device. When the input signal exceeds the
VAGCThreshold, the VAGC alters the receive audio so that it remains between the VAGCLow Target and
VAGCHigh Target.
lVAGC Max Loss (dB) – The highest amount of dB loss, in decibels, that can be adjusted to this device using
VAGC.
lVAGC Max Gain (dB) – The highest amount of dB gain, in decibels, that can be adjusted to this device using
VAGC.
lVAGCThreshold (dB) – The level, in decibels, at which the Software Media Workstation outputs audio to this
external audio interface.
IMPORTANT
Use caution when setting these fields. Avtec recommends first adjusting the Windows Input Level (%) and
Mic Gain (dB) fields before attempting to adjust any VAGCsetting. Mic Gain (dB) adjustments should only
be made in small increments.
