Configuration Settings Tab Parameters

The easiest way to configure Nyquist appliances is to obtain configuration settings from the Nyquist server by selecting Get Configuration From Server. However, you can manually configure an appliance through the appliance’s Web UI when Standalone Operation is enabled (see"Standalone Operation Configuration Settings").

To view or modify the Nyquist appliance configuration:

1On the appliance Web UI’s main page, select Configuration Settings.

2View the settings as described in Table 5 for normal configuration, or modify the settings as described in"Standalone Operation Configuration Settings" for Standalone Operation configuration.

3If changes were made (Standalone Operation only), click the Save Configuration Settings and/or Save Multicast Addresses buttons to save your changes.

The following table describes the Configuration Settings tab settings when Standalone Operation is not enabled for this device:

Table 5. Configuration Settings (Standalone disabled)

Get Configuration from Server

Retrieves configuration settings (i.e., web username, server, and local port) from the TFTP server specified in the Network Settings (see Table 1).

Web Username

Displays the username of the current user.

Emergency-All-Call

Identifies the IP address, port number, cut level (volume), and station list used for emergency all-call pages.

All-Call

Identifies the IP address, port number, cut level (volume), and station list used for all-call pages.

Audio Distribution

Identifies the IP address, port number, cut level (volume), and station list used for audio distribution.

Multicast #

Identifies the IP address, port number, cut level (volume), and station list used for the multicast audio stream of one (or more) zones.

Nyquist Control Password

Specifies a password used to secure Nyquist control messages between this device and the Nyquist server. This value must match the password specified on the Nyquist server to support certain Nyquist features, such as sound masking, amp protection mode, and station check-in.

The specified password must be exactly 20 characters long and include uppercase, lowercase, and numeric characters.

Note: This password cannot be set unless the Web Password has been changed from the default value.

The Configuration Settings tab also displays the following information for each Device Station attached to the amplifier:

Port Number

Shows the port number of the appliance.

Port Type

Shows the station type to which the port connects.

Account ID

Shows the SIP account (IP address) associated with the device preceded by the extension of the device associated with this port.

Local Port

Shows the port used for SIP.

Username

Shows the username or extension for the station associated with the port.

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 input multicast addresses (and ports) from which the device will receive digital signals, which will then be converted to analog and played to the speaker output.

To use this device to make announcements or SIP calls, connect a Push-to-Talk (PTT) microphone to the speaker and call switch connections (refer to the VoIP Intercom Module Installation and Use Guide).

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., speaker) on which to play the received (and decoded) audio signal.

The following table describes the Configuration Settings tab settings when Standalone Operation is enabled for this device:

Table 6. Configuration Settings (Standalone enabled)

Device Type

The extension, along with the IP address, is used to specify the URI used to place a SIP call to this extension:

sip:<extension>@<local_ip_address>

SIP Usernamea

Specifies the SIP username used to register with the SIP server.

SIP Passworda

Specifies the SIP registration password used to register with the SIP server.

Talkback Gaina

Input gain applied to talkback for intercom calls.

This can be a value from -12 to 20 dB.

Typea

Specifies how the device will be used. Options are:

VoIP Speaker Only

Digital Call Switch & Speaker

Dial Extensiona

Only available when Type is set to Digital Call Switch & Speaker, this indicates which extension will be called when the call button is activated.

Intercom Cut Levela

Cut level for intercom calls.

This can be a value from -42 to 0 dB.

The following parameters appear for each Multicast Address configured for this device.


Multicast IP Address

Specifies the multicast IP address on which to receive audio streams.

Multicast Port Number

Specifies the multicast port on which to receive audio streams.

Codec

Specifies the codec to be used when decoding audio. Select one of the following values:

G711 u-law
