Configuring the Nyquist AoIP Gateway
The Nyquist GA400P AoIP (Audio over IP) Gateway provides the ability to receive an
analog signal, convert it to a digital signal, and send it to a partner device across a net-
work. It can also receive a digital signal over a network, convert it to an analog signal, and
play it back through a speaker.
Used in conjunction with other AoIP Gateway devices—or other systems offering similar
SIP-related capabilities—this highly flexible device provides the critical function of con-
verting analog signals (like voice or music) to and from digital signals. For example, with
the use of such additional components as speakers and microphones, this gateway
device allows you to:
• Enable music to a remote device on the network.
• Send and receive announcements over the network.
A short press of the appliance’s Reset button reboots the device. If you press the Reset
button for 10 seconds, the appliance returns to the factory default configuration settings.
Returning to the default configuration settings does not change the appliance’s firmware.
The following sections describe settings and configurations that can be applied to this
device which are not controlled by the Nyquist server. For information about using
Nyquist’s automatic configuration process, refer to the appropriate Nyquist System
Administrator Guide.
To access the appliance’s user interface (UI):
1Access the appliance’s web UI by doing one of the following:
a) On your web browser, enter the IP address for the appliance as the URL.
b) From the Nyquist web UI navigation bar, select Stations, select Stations Status or
Appliance Status, navigate to the device that you want to configure, and then
select the Link icon.
Note: Do not use third-party Chrome browser extensions with the Nyquist user inter-
face.

Standalone Operation
This device can run in Standalone Operation mode, where it will not interact with a
Nyquist server (e.g., E7000 or C4000). This means the device will not:
• Fetch device configuration from Nyquist server
• Register with Nyquist server (via SIP)
• Store backup information to Nyquist server
• Allow access to Nyquist server-based NTP
Standalone Operation mode is ideal for scenarios that do not require the full functionality
provided by an integrated system, such as the Bogen C4000 or E7000 Series, but has the
ability to provide paging, multi-channel audio processing, and a SIP endpoint for a PBX/
VoIP phone system. It can be used to play music, audio, paging, and related functions.
Updating Firmware
When you select Firmware Update from the appliance’s web UI, the Firmware Update
page appears. From this page you can determine which Nyquist firmware version the
appliance is using and if an update is available. You can also load a firmware release,
install the loaded firmware, restore the configuration to factory defaults, and reboot the
appliance.
Note: A Nyquist appliance connected to the Nyquist network receives a configuration
file from the Nyquist server that includes the latest firmware available from the server.
If the firmware is different from the one installed on the appliance, an automatic firm-
ware update occurs unless the Firmware parameter for the station is left blank. Refer to
the Nyquist System Administrator Guide for more information.

5
To use the Firmware Update page:
1On the appliance web UI’s main page, select Firmware Update to view or update the
firmware version.
2If the device is in Standalone mode, selecting the Check for Updates button checks
the Bogen website for the latest firmware version available. If a version newer than
the one currently installed is found, it is downloaded to the appliance.
3If you already have a firmware file you would like to install to the appliance, select
Upload Firmware to upload the firmware file from your computer to the appliance. A
popup screen appears that allows you to select the file that you want to upload. You
can navigate to the file’s location. After you select the file, select Upload.
4The page displays the uploaded firmware version (“New Nyquist Version”) and an
Update Firmware button appears. Select this button if you want to update the appli-
ance’s firmware to the uploaded version.
5If you want to return your appliance to its original factory configuration, select
Restore Factory Settings.
6Select Reboot Appliance to restart your appliance.

NTP Server Identifies the IP address or the domain name of the
Network Time Protocol (NTP) Server.
Note: This field is only editable when Standalone
Operation is enabled.
TFTP Server Identifies the host name or IP address of the Trivial
File Transfer Protocol (TFTP) server.
The specified TFTP server can be used to automati-
cally set this device’s Configuration settings via the
Get Configuration from Server button.
If TFTP Server from DHCP (see below) is set to “Yes”,
this value will be auto-configured via DHCP option
66, assuming the DHCP server has been configured
to provide option 66. For details, see the documenta-
tion for your DHCP server.
Note: A TFTP server runs on the Nyquist server on
port 69 (the standard TFTP port) and the optional
Nyquist DHCP service automatically provides this
TFTP address via option 66.
Note: If this value is unspecified, the TFTP Server
from DHCP will automatically be set to “Yes”, this
field will become read-only, and DHCP will be used to
configure this setting. To change this value, the TFTP
Server from DHCP setting must be set to No, which
makes the field editable.
Note: This setting is not available when Standalone
Operation is enabled.
TFTP Server from DHCP “Yes” means the device will use the DHCP option 66
value to retrieve an address for the TFTP Server from
DHCP.
“No” means the device will ignore the DHCP option
66 value and use the manually configured value of
the TFTP Server (see above).
Note: This setting is not available when Standalone
Operation is enabled.

Standalone Operation Configuration Settings
Configuring this device consists of specifying one or more of the following:
• The SIP server addresses, ports, and SIP extensions at which to register for incoming
SIP pages and announcements.
• The output multicast (Audio Cast) addresses (and ports) to which the device will send
one or more digitized line input signals.
• The input multicast addresses (and ports) from which the device will receive digital
signals, which will then be converted to analog and played to one or more line out-
puts.
To use this device to make announcements or SIP calls, connect a microphone to one of
the Line Input ports (possibly through a preamp device, which would convert the mic-
level signal to a line-level signal). For the Multicast Addresses (Audio Cast) entry whose
channel matches the line input port, specify a codec, cut level, and multicast address and
port to which the signal will be streamed. That stream can be consumed by one or more
devices to receive announcements or SIP calls.
To receive announcements or SIP calls, configure one or more Multicast Addresses
entries with the multicast addresses and ports from which to receive the input streams.
Specify a codec, cut level, and output channel (i.e., Line Output port) on which to play the
received (and decoded) audio signal.
Port Number Shows the output port/channel number of the appli-
ance.

The DSP page displays a mixing board console containing two input strips and two
output strips. The input strips accept the analog inputs from the line input connectors
and—after gain adjustments, analog-to-digital conversion, and DSP enhancements—
send the digital network send over the network. The output strips accept the digital net-
work receive from the network and—after DSP enhancements, digital-to-analog conver-
sion, and gain adjustments—send the analog output to the line output connectors.
