Nyquist Frequently Asked Questions

Q: Does the Nyquist system use/require static IP addresses, or can it be allocated dynamic IP addresses by DHCP?

A: It is recommended that the Nyquist server be allocated a static IP address, whereas the appliances and VoIP Phones can be installed with dynamic IP addresses to simplify installation. Some network engineers may prefer to issue static IP addresses rather than having to set up DHCP specific for each campus/school, and all of the Nyquist appliances and phones can be configured with static IP addresses if desired.

Q: How do I determine if Option 66 of the DHCP server will be used to automatically configure equipment via the TFTP?

A: Contact the network administrator or network engineer at the site; he or she can answer this question.

Q: Can one Nyquist server be used to manage all schools in the school district?

A: It is not recommended because using one server for all locations eliminates the ability to do Emergency and All-Call pages at an individual campus/school only.

Q: Does Nyquist need to be installed on a dedicated network?

A: No.

Q. Does the Nyquist server require an Internet connection?

A: Yes; an Internet connection is needed as a part of installing the Debian operating system (OS), installing the Nyquist application, and activating or updating the License Activation Key. After the system is set up the Internet connection is no longer needed for day to day operation.

Q: Which web sites must be whitelisted for the Debian OS and Nyquist server installations?

A: You must be able to access the following URLs :

The default URLs for the STUN and TURN servers are not set. The default URL for Network Time Server (NTS) is pool.ntp.org.

Q: How can I obtain the correct version of the Debian OS software?

A: Nyquist requires version 8.9.0 (aka “jessie”), which can be downloaded either from http://www.bogenedu.com/secure-login/ in the Nyquist Dealer Resources or https://www.debian.org.

NOTE: Access to this and other Nyquist resources is restricted to approved Nyquist dealers. If you would like access to all Nyquist dealer resources, apply for access here.

Q: When installing Debian, what predefined collection of software should be selected for install?

A: As a minimum, the Debian install should include GNOME, web server, SSH server, and standard system utilities.

Q: Is remote access to the Nyquist server required?

A: Remote access is not required, but can be very helpful. Bogen support staff may request remote access into the Nyquist server to allow us to run diagnostics and to assist with troubleshooting.

Q: How can I obtain the Nyquist software?

A: The Nyquist software is available for download from the Nyquist Dealer Resources on http://www.bogenedu.com/secure-login/.

NOTE: Access to this and other Nyquist resources is restricted to approved Nyquist dealers. If you would like access to all Nyquist dealer resources, apply for access here.

Q: What is a License Activation Key and when is it required?

A: The License Activation Key is provided by Bogen to activate your Nyquist system license. It is used during the initial Nyquist installation and anytime you need to increase the number of stations or concurrent calls handled by your Nyquist server.

Q: How do I obtain a License Activation Key?

A: License Activation Keys are emailed to the dealer when a system ships.

Q: Can I obtain a demo License Activation Key?

A: Yes; a Nyquist certified ES Dealer must place a purchase order (PO) for a Nyquist demo system.

Q: Do I need an Uninterruptible Power Supply (UPS) for my Nyquist server?

A: While using a UPS is not mandatory, Bogen strongly recommends its use to help protect the Nyquist system during sudden power surges or outages.

Q: How do I create bootable media for use during installation?

A: Debian CD and DVD images can be written directly to a USB stick, which is a very easy way to make a bootable USB stick. Choose a CD or DVD image that will fit on your USB stick. Go to https://www.debian.org/ to download a CD or DVD image.

The CD or DVD image you choose should be written directly to the USB stick, overwriting its current contents. For example, when using an existing GNU/Linux system, the CD or DVD image file can be written to a USB stick as follows, after making sure that the stick is unmounted:

# cp debian.iso /dev/sdX# sync

The win32diskimager utility can be used under other operating systems to copy the image.

The image must be written to the whole-disk device and not a partition, e.g., /dev/sdb and not /dev/sdb1. Do not use tools such as unetbootin, which alter the image.

Q: How do I configure the Nyquist server BIOS to boot from the Debian install media?

A: Depending on the server manufacturer, pressing the F10, the F12, or the Delete key repeatedly during power up should bring you to the system BIOS. Once in the system BIOS, navigate the menu to find the device Boot sequence and arrange the devices with the Debian media as the first device in the Boot order.

Q: How do I determine what server platform to use as a Nyquist server?

A: We recommend searching the Debian wiki page (https://wiki.debian.org/) for servers and server configurations that are supported by Debian 8.9.0.

Q: If desired, what type of RAID should the Nyquist server use?

A: Generally speaking, Debian works best with hardware-based RAID controllers. We recommend searching the Debian wiki page (https://wiki.debian.org/) for server configurations that are supported by Debian 8.9.0.

Q: What is the best way to deploy multicasting?

A: Any Class-D IP address can be used when setting up multicasting on a Nyquist system. By default, we start with address and increment higher as needed.

Q: Can the system be deployed over different subnets, VLANs, or both, and if so, what configuration steps must be done?

A: The ideal Nyquist implementation should be over a flat network. However, if that is not possible and the system will be deployed over different subnets, VLANs, or both, then PIM on the Layer-3 VLAN Interface, IGMP Querier on Layer-2 switches, or both needs to be implemented; discuss this with your IT contact at the school.

Q: What kind of PoE switch does a Nyquist system need?

A: The Nyquist VoIP speakers and I/O Controllers are Class-3 PoE 802.3af devices. Make sure that the switch these devices are connected to can provide sufficient power for the total number of PoE devices you are planning to connect to it.

Q:Does a Nyquist system need a dedicated router?

A: A dedicated router, one or more Layer-2 switches, or both will be required if the Nyquist system is installed on its own private network. However, even when intending to install Nyquist on the customer’s network, a ”temporary” router is also handy during installation to initially assign dynamic IP addresses to the appliances if it is required by the site to configure static IP addresses on each device.

Q: What types of telephony integrations does Nyquist support?

A: There are basically four ways Nyquist can interface with a customer’s telephony environment:

  1. SIP trunks to PSTN or Cloud-based VoIP provider
  2. SIP Tie-Lines to the premises-based IP-PBX
  3. FXO/FXS lines to the PSTN or premises-based PBX or IP-PBX
  4. SIP-ATA to the premises-based PBX or IP-PBX

The first three optons allow full bi-directional calling between Nyquist stations and the IP-PBX/PBX/PSTN and supports features like E-911 calling, remote call transfer, off-premise calling, etc.  The fourth approach only allows a station on the PBX to ”dial through” to the Nyquist system where it will draw a second dial tone to initiate DTMF controlled paging, intercom calls, etc.

Q: If I need an FXO or FXS integration between Nyquist E7000 and my PBX or the PSTN, where can I get information about the correct FXO/FXS telephony interface card(s) to order?

A:The Nyquist platform integrates with FXO/FXS telephony interface cards from Digium, Inc. Use the hyperlink to view Digium’s datasheet on the A4A and A4B analog cards to determine which combination of card(s) and FXO/FXS port modules best suits your integration needs and your Nyquist server platform’s PCI/PCI-E slot configuration. The A4 series of analog cards supports up to four FXO/FXS port modules per card.

NOTE: If your installation requires FXS ports, you need to order the PWR2400B accessory. The PWR2400B provides the 12V DC power to analog interface cards that is necessary to drive FXS modules. FXS ports require a substantial amount of 12V DC power to provide ringing voltage and battery to the connected telephones or handsets, and the PCI/PCI-E interface on PC/server motherboards cannot provide sufficient voltage. Since FXO modules do not provide ring voltage or battery, they do not require any external power resources.


Q: Does Nyquist support Apple iOS?

A: Yes, for accessing and configuring system features and options (for example, System Parameters, Admin Groups, Stations, etc); however, the Nyquist Dashboard does not function in an iOS environment.

Q: What operating systems are fully support by Nyquist?

A: Android, Mac OS, and Windows using a Chrome browser.


Q: If a school has say 100 classrooms that want occasional, random access to the Nyquist Web UI, can they simply purchase a small ‘pool’ of station licenses (e.g., 20) for those classrooms?

A: Each Web UI user must have a unique username, password, and pre-assigned station number assignment.  So, if the school wants each of the 100 classrooms to have unblocked access to the Nyquist Web UI login, they would need 100 dedicated station licenses.  However, if the school wants to just create a “pool” of generic Web UI user accounts, they can purchase fewer station licenses (e.g., 20), but teachers would likely need to try to log in multiple times with different usernames to try to find an account in the pool that is available.  This would not likely offer a good user experience.
