Configuring the Analog Station Bridge
The Nyquist Analog Station Bridge (ASB) allows the Nyquist solution to use the existing
analog call switch and speaker infrastructure when upgrading from Multicom 2000,
Quantum Multicom IP, and third-party intercom systems. When used exclusively as a net-
worked component of the Nyquist paging and intercom solution, the Nyquist ASB per-
mits a hybrid Internet Protocol (IP)/analog system configuration through use or
connection of analog 25V speakers and associated analog call switches (for example,
CA15C type). This ASB has 24 station connections that attach to wired speakers and their
associated call switches. While each connection has its own Session Initiation Protocol
(SIP)–addressable Station ID, the ASB itself uses a single network IP address.
The Nyquist server can automatically discover and configure the ASB, but you can also
manage the device, and manually configure some settings, through the ASB’s web-based
user interface (web UI).
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 auto-
matic configuration process, refer to the Nyquist System Administrator Guide.
To access the appliance’s 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 Bridge Devices, then select the
Link icon to open the device web interface for the selected device.
c) From the Nyquist web UI navigation bar, select Stations, select 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 interface.

2At the Nyquist Appliance - Login page, enter username and password, and then select
Login.
The dashboard for the selected appliance appears.
Using the Dashboard
The ASB dashboard displays information about the ASB, including LEDs and temperature
output that provides status of the ASB. You can also make temporary adjustments to the
ASB volume using a volume slider that appears at the bottom of the ASB dashboard. The
volume can be adjusted on a scale from -42 dB to 0 dB.
Figure 1. Nyquist Appliance Login

The dashboard displays the following fields:
Real-time statuses that can be viewed from the dashboard are described in the following
table:
Figure 2. Nyquist Analog Station Bridge Dashboard
Table 1. Appliance Dashboard Fields
Device Type Displays the model of this device.
Serial Number Displays the serial number for the device.
MAC Address Displays the Media Access Control (MAC) address, which
is a unique identifier assigned to network interfaces for
communications on the physical network segment.
Firmware Version Displays the firmware version installed on the station.

Table 2. ASB Status Indicators
Channel 1/2 Status Provides clipping status for Channel 1 and 2. Clipping is
sound distortion that occurs when an amplifier attempts
to deliver an output voltage or current that is beyond its
maximum capability. If this indicator is green, the channel
is not clipping. Red means the channel is clipping. Gray
means that the appliance’s web UI is not receiving data
from the appliance's web server, indicating that the ASB
may be offline or rebooting.
Protection Status Indicates if the ASB is in partial shutdown mode to protect
the built-in two-channel amplifier module.
In this case, the appliance itself may remain “on” as indi-
cated by its front panel Status and Power LEDs. However,
the ASB’s amplifier module senses various faults that can
be caused by factors such as incorrect speaker wiring (for
example, shorts or too low an impedance). These faults
can overload the amplifier output capability (overcurrent/
clipping) and/or amplifier thermal conditions (overheat-
ing).
If the indicator is green, the amplifier module is operating
in a normal capacity. If the indicator is red, the amplifier
module is in protection mode and audio will not be passed
to any ASB port. If the cause is temporary or intermittent
(for example, signal clipping), the amplifier module will
quickly return to normal mode.
If the system remains in protection mode for an extended
period of time, this likely indicates some sort of wiring
fault or low-impedance condition is present that must be
rectified.
When the indicator is gray, the ASB's web UI is not receiv-
ing protection status information from the appliance’s web
server. This usually indicates that the network connection
has been interrupted or dropped or that the device is
rebooting.

5
The following buttons are available at the top of all pages in the application.
Temperature Provides a snapshot of the amplifier module’s temperature
in degrees Celsius during any transition (that is, change
state) on the Channel 1, Channel 2, or Protection Status
indicators.
Note: The ASB’s UI displays the temperature reading from
the latest update; it does not receive or display continuous
real-time amplifier module temperature readings.
Volume Sets the volume for the speaker during an intercom call or
page. This is a temporary adjustment that allows the user
to experiment with the loudness of the speaker. To make
permanent adjustments, change the various cut level set-
tings on the Nyquist System Controller.
The value can be adjusted between -42 dB and 0 dB.

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.
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 config-
ure this setting. To change this value, the TFTP Server
from DHCP setting must be set to No, which makes
the field editable.
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).
DHCP Enabled Indicates if the device is enabled to use DHCP to
retrieve its IP configuration.
