Environmental Considerations

  • Operating Voltage: 110 – 240VAC
  • Operating Frequency: 50 – 60Hz

The NTA1000 includes a full range power supply suitable for use in most countries.

Getting Started

Your copy of CDRouter has been pre-installed on QA Cafe’s NTA1000 network test appliance. The NTA1000 is a fully integrated system that has been optimized for use with CDRouter. The NTA1000 is equipped with a high performance Intel Core2Duo processor, four gigabytes of memory, an integrated Atheros AR9160 dual-band 802.11 a/b/g/n wireless LAN adapter, and six on-board Intel 82574L Gigabit Ethernet network interfaces. Additional interfaces are available for other data link layers including ATM and T1/E1 upon request. For a detailed listing of product specifications, please see the NTA1000 Data Sheet. Please see Section 10 for a complete listing of online resources.

Please identify a suitable location for your NTA1000. Installation of the included rubber feet is recommended if you plan to use the NTA1000 as a workstation on a flat surface. The rubber feet will prevent the NTA1000 from sliding. Note that the interior bracing of the NTA1000’s metal chassis allows other devices to be stacked upon it, including other workstations or monitors.

If you choose to situate the NTA1000 in a 19 inch rack, please be advised that the rack mount ears are intended for lateral locking only and are not load bearing. It is recommended that the NTA1000 be installed on an industry standard 19 inch rack shelf to ensure proper safety. The NTA1000 is 1U in rack height.

The NTA1000 has an electrical cutoff switch on the rear of the unit. Please ensure it is toggled to the 0 position before you connect the provided power cord. After you have read the rest of these instructions, you can power the NTA1000 on by toggling the switch to the 1 position. A standard VGA display port is provided at the rear of the unit. Any USB keyboard and mouse may be connected to the two USB ports at the front of the unit.

Network Interfaces

Ethernet (Wired Connection)

The front of the NTA1000 contains six Ethernet ports. The eth0 interface is not used by CDRouter and is intended for remote access. To access the NTA1000 from your production network, please connect an Ethernet cable from eth0 to an Ethernet port on your production network’s hub or switch. Configuring the eth0 IP address is covered in its own section below.

The remaining five Ethernet interfaces, eth1 through eth5, are intended for use as test interfaces by CDRouter and must not be configured with IP addresses. The CDRouter example configurations will demonstrate how to use these interfaces in your testing environment.

802.11 Wireless

The NTA1000 includes an Atheros AR9160 802.11 wireless LAN PCI adapter. This adapter provides access to 802.11a, 802.11b, 802.11g, and 802.11n networks on the 2.4GHz and 5GHz radio frequencies. Three dual-band antennas with magnetic mounting bases are provided. The magnetic mounting bases are equipped with six foot cords that should be connected to the three RP-SMA connectors on the rear of the NTA1000. This arrangement allows the NTA1000 to be placed inside a rack or enclosure without compromising wireless signal integrity. We recommend experimenting with different placements throughout your testing area, to determine optimal signal strength.

If the NTA1000 has been equipped with an optional ATM adapter, a dual-band Atheros AR9170 USB-based wireless LAN adapter and extender cable will be provided instead. The USB wireless adapter supplied with the NTA1000 is functionally equivalent to the PCI based version supplied by default.


The NTA1000 can be optionally equipped with an Ericsson (formerly Marconi) ForeRunner HE 155 ATM adapter. The ForeRunner HE 155 is a PCI interface adapter that supports multimode ATM OC-3 connections. Installation of the ForeRunner HE 155 allows CDRouter to connect directly to ATM-based DSLAMs on the WAN. For more information on testing DSL CPE devices using ATM-based DSLAMs, please see this Application Note. Please also refer to our Knowledge Base.

Accessing and Managing the NTA1000

The NTA1000 can be managed from the front panel serial interface or from the Linux Gnome Desktop. Users who are not familiar with Linux will find the Gnome Desktop more intuitive. The serial interface is intended for command line management and allows the NTA1000 to be used without a video monitor.

Serial Management

The NTA1000 is fully configurable via the front panel RS232 serial interface. The BIOS, bootloader, and Linux root system shell can all be accessed in sequence from system bootup by plugging a terminal into the serial interface located on the front panel. The following settings are required for serial access:

  • 115200 baud
  • 8 data bits
  • No parity
  • 1 stop bit

Please contact for more information on using the NTA1000 serial port interface.

Linux Desktop Management

It is also possible to use a VGA capable display and any USB keyboard and mouse to access the full Linux Gnome Desktop of the NTA1000. If connected, the system will automatically log in to a customized Gnome Desktop as the qacafe user. This user has custom menus available for accessing QA Cafe specific resources.

Default User and Password

The default user for the NTA1000 is qacafe and the default password is cdrouter. There is no administrator account enabled by default. To perform administrator commands, please use the sudo command using the default password. The sudo utility provides arbitrary administrative control to user accounts. This safeguards the system against accidental changes. Under normal operation, you will not need to perform any sudo commands.

Configuration of the eth0 Network Interface

Warning: The NTA10000 is not intended for use on a public network, and does not include any firewall software. If you intend to deploy your NTA1000 on a public network, please consult with your firewall administrator before assigning the NTA1000 an IP address. Private test results may be exposed if this scenario is not carefully considered.

The NTA1000’s eth0 interface is configured by default for DHCP. If you do not change the eth0 configuration, it will attempt to lease an IP address from your corporate LAN. If it successfully receives an IP address, it will be listed on the front panel LCD shortly after the lease process completes. If the lease fails, the LCD will indicate that no IP address has been configured.

If you wish to configure a static address on eth0, please follow these instructions:

From the Front Panel Serial Interface

Once the NTA1000 has loaded, you can access a system terminal by using the previously listed RS232 parameters. Tap the Enter key on your terminal to invoke a login prompt. Use the qacafe user credentials, also listed previously. Skip the next section “From the Gnome Desktop”, and continue with “Assigning a Static IP to eth0”.

From the Gnome Desktop

Under the Applications menu, click Accessories, and then launch the Terminal application.

Assigning a Static IP to eth0

In the terminal, type the following command:

$ sudo nano /etc/network/interfaces

This will launch the nano text editor. You can use the arrow keys to navigate through the file contents.

By default, the eth0 interface will be configured as the following:

auto eth0 
iface eth0 inet dhcp

To give the eth0 interface a static configuration, you must delete the above configuration and replace it with the following example. Please substitute your own network settings:

auto eth0 
iface eth0 inet static 

When you assign a static IP address to the system, it will retain the previous DNS information obtained from DHCP. To update DNS server configuration, edit the file /etc/resolv.conf. Inside, simply include the following line:


Substitute your own DNS server address for the above. Once the file is updated, save and exit the editor. The change takes effect immediately.

Note: You must not configure any other Ethernet interfaces in this file. CDRouter will fail to start if the Operating System has configured any interfaces other than eth0.

Once you have made the changes, press control-o to save the file. Hit Enter to accept the filename. After nano has saved the configuration, type control-x to exit nano. You must restart the networking service for any changes to be applied. Please issue the following command:

$ sudo /etc/init.d/networking restart

You may now close your terminal, either by typing exit or clicking the “X” icon on the terminal’s titlebar.

Using CDRouter

Now that your NTA1000 is configured with an IP address on its eth0 interface, it is accessible from any workstation in the test lab with a web browser.

CDRouter is accessible by many web browsers, including Firefox, Safari, and Google Chrome.

To access CDRouter, load your web browser and enter the following URL:

http://<eth0 ip address>:8015/

For example, if the eth0 IP address is, then the CDRouter URL is:

Congratulations! You have now accessed CDRouter’s primary user interface! From here, you can use CDRouter’s online help as you learn how to build custom configurations for testing your devices. Please see the CDRouter Quick Start Guide for more information.

Note that it is also possible to run CDRouter using the command line interface from a terminal. Please see the CDRouter User Guide for more information on running CDRouter from the command line.

Performing Test Result Backups

QA Cafe recommends that you periodically backup the test results stored on you NTA1000 to prevent data loss in the event of a disk failure. Please see our Application Note on CDRouter data backups for more information.
