NV-600AI is an Industrial VDSL2 router equipped with four Gigabit LAN ports. It is compliant to ITU-T G.993.2
and G.993.5 standards and supports VDSL2 profile 30a that features 100Mbps of symmetric data. NV-600AI is
perfectly suitable for triple-play applications. Housed in metal DIN rail enclosures, these routers are designed
for harsh environments, such as industrial networking and utility market applications.


Vectoring Technology friendly Mode support

Vectoring is a transmission method that employs the coordination of line signals for reduction of crosstalk levels and improvement of performance. It is based on the concept of noise cancellation, much like noise-cancelling headphones. The ITU-T G.993.5 standard, "Self-FEXT cancellation (vectoring) for use with VDSL2 transceivers" (2010), also known as G.vector, describes vectoring for VDSL2. The scope of Recommendation ITU-T G.993.5 is specifically limited to the self-FEXT (far-end crosstalk) cancellation in the downstream and upstream directions. The far end crosstalk (FEXT) generated by a group of near-end transceivers and interfering with the far-end transceivers of that same group is cancelled. This cancellation takes place between VDSL2 transceivers, not necessarily of the same profile.


Easy Installation

The NV-600AI may be installed on any level surface (e.g. a table or shelf or rail) that use bracket or DIN rail plate.

NV-600AI supports plug-and-play installation and is fully compatible with all kinds of network protocols. Furthermore, user can watch the status of each individual port via the LED indicators.


Enhanced Management

For efficient management, via Web interface, the NV-600AI can be programmed for advanced management functions such as QoS (Quality of Service)/DSCP, IEEE 802.1q Tag VLAN, SNMP v1/v2c/v3, IGMP v3 and enhanced security functions such as Packet filtering, DMZ, Mac Address based filtering, Parental Control, Application based filtering.


About harsh environment applications

The NV-600AI can used in the harsh environment, such as -20°C ~ 70°C (-4°F ~ 158°F), and metal case compliant with the IP-30 design. The design of the IP-30 can prevent the invasion of small stones within the NV-600AI.

1. What is NV-600AI related products?


NV-600AI can fully compatible with NV-802S,NV-600LI.


2. POWER indicator does not light up (green) after power on.


Check the power plug by plugging in another that is functioning properly. Check the power cord with another device. If these measures fail to resolve the problem, have the unit power supply replaced by a qualified distributor.


3. Link indicator does not light up (green) after making a connection.


Network interface (ex. a network adapter card on the attached device), network cable, or switch port is defective.

• Power off and re-power on the VDSL bridged.

• Verify that the bridge and attached device are power on.

• Be sure the cable is plugged into both the bridge and corresponding device.

• Check if the proper cable type is used and its length exceed specified limits.

• Check the bridge on the attached device and cable connections for possible defects.

• Replace the defective bridge or cable if necessary.


4. Why is the VDSL Link cannot be established.


  1. VDSL setting failure or phone cable length is over the specification limit.
  2. Solutions:
  3. 3.1 Please make sure that the phone wire must be connected between NV-600LI(CO) and NV-600AI (CPE) when both are power on. NV-600LI (CO) will do link speed function depending on phone wire length, therefore if NV-600LI (CO) can’t detect NV-600AI (CPE) over phone wire while both power on, this will cause the link to fail.
    3.2 Please check phone wire, we recommend use 24-26 gauge with twisted pair and without rust.
    3.3 Please reinsert power when change cable length or link time over 3 minutes.
  4. Note:
  5. Phone wire must meet CAT 3 standard or above and without clustering, otherwise will cause more cross talk issue to reduce DSL power driver.


5. What is VDSL2?


Very-high-speed digital subscriber line 2 (VDSL2) is an access technology that exploits the existing infrastructure of copper wires that were originally deployed for traditional telephone service. It can be deployed from central offices, from fiber-optic connected cabinets located near the customer premises, or within buildings. It was defined in standard ITU-T G.993.2 finalized in 2005.
VDSL2 was the newest and most advanced standard of digital subscriber line (DSL) broadband wireline communications. Designed to support the wide deployment of triple play services such as voice, video, data, high definition television (HDTV) and interactive gaming, VDSL2 was intended to enable operators and carriers to gradually, flexibly, and cost-efficiently upgrade existing xDSL infrastructure.

The protocol was standardized in the International Telecommunication Union telecommunications sector (ITU-T) as Recommendation G.993.2. It was announced as finalized on 27 May 2005,[1] and first published on 17 February 2006. Several corrections and amendments were published in 2007 through 2011.

VDSL2 is an enhancement to very-high-bitrate digital subscriber line (VDSL), Recommendation G.993.1. It permits the transmission of asymmetric and symmetric aggregate data rates up to 200 Mbit/s downstream and upstream on twisted pairs using a bandwidth up to 30 MHz.

VDSL2 deteriorates quickly from a theoretical maximum of 250 Mbit/s at source to 100 Mbit/s at 0.5 km (1,600 ft) and 50 Mbit/s at 1 km (3,300 ft), but degrades at a much slower rate from there, and still outperforms VDSL. Starting from 1.6 km (1 mi) its performance is equal to ADSL2+.

ADSL-like long reach performance is one of the key advantages of VDSL2. LR-VDSL2 enabled systems are capable of supporting speeds of around 1–4 Mbit/s (downstream) over distances of 4–5 km (2.5–3 miles), gradually increasing the bit rate up to symmetric 100 Mbit/s as loop-length shortens. This means that VDSL2-based systems, unlike VDSL1 systems, are not limited to short local loops or MTU/MDUs only, but can also be used for medium range applications.


6. What is SNR(Signal-to-Noise)


Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. It is defined as the ratio of signal power to the noise power. A ratio higher than 1:1 indicates more signal than noise. While SNR is commonly quoted for electrical signals, it can be applied to any form of signal (such as isotope levels in an ice core or biochemical signaling between cells). The ratio is usually measured in decibels(dB)

The signal-to-noise ratio, the bandwidth, and the channel capacity of a communication channel are connected by the Shannon–Hartley theorem.

In digital communications, the SNR will probably cause a reduction in data speed because of frequent errors that require the source (transmitting) computer or terminal to resend some packets of data. SNR measures the quality of a transmission channel over a network channel. The greater the ratio, the easier it is to identify and subsequently isolate and eliminate the source of noise.


7. Connected the Co and CPE within 300 meters RJ-11 phone cable got only less than 10 Mbit/s
  1. Cause:
  2. • Some testing program which is base on TCP/IP protocol such as FTP, Iperf, NetIQ, the bandwidth of testing outcome will be limited by TCP window size.

    • Some operating system limited the maximum bandwidth, such as windows series OS.


    We recommend to test VDSL2 bandwidth best by Smartbit equipment (Packet generator), if you don't have Smartbit, we recommend test that by IPERF program, and TCP window size must be setted max. 64k, the parameter as iperf –c server IP address –i 1 –t 50 –w 65535 for client side.

8. We need to set up a default gateway on a NV-600 pair which are in Bridge mode, as they want to manage the units from a different network.


When the application is used within the LAN, the switch(bridged) mode is not necessary to set up a gateway .However, if the application crosses various network segments (LAN to WAN or WAN to LAN), you must set up a gateway to connect different network segment.
Regarding how to configure a default gateway at switch(bridged) mode for crossing various network segments , please refer to the section 4.8.1 for your reference.
Configuration gateway example from static routing:
Destination LAN IP: 0-0-0-0
Subnet Mask: 0-0-0-0
Gateway:  255-255-255-0

Note: Static Routing functionality is used to define the connected Gateway between the LAN and WAN.


9. Is it possible to use ADSL2 IP DSLAM with the NV-600AI?


NV-600AI support the ADSL Annex A/B backward compatible, therefore the NV-600AI can connect to ADSL2 IP DSLAM.


10. What can I do if I forgot my password?


If you forgot your password, you must reset your router. This process will change all your settings back to the factory default. To reset the router, locate the reset button on the rear panel of the unit. With the router powered on, use a paperclip to hold the button down for over 5 seconds. Release the button and the router will go through its reboot process. The default IP is When logging in, the default username and password are both “admin”.


11. What is the maximum Ethernet frame MTU for these routers?


NV-600AI maximum Ethernet frame MTU is 1680 bytes.
