NV-700I is a Managed Single Master LAN Extender that leverages the extraordinary bandwidth promise of VDSL2 technology (max. 100Mbps symmetric), the next step in the delivery of new high-speed Internet applications in Industrial-grade environments. Quick, easy, economical to install and maintain, the NV-700I works over existing copper wire infrastructure. NV-700I is a Master(CO side) , which it's designed to interconnect with NV-600AI (CPE) for point to point application.

NV-700I will allow operators worldwide to compete with cable andsatellite operators by offering services such as HDTV, VOD, videoconferencing, high speed Internet access and advanced voice services including VoIP, over a standard coppertelephone cable. NV-700I is seen by many operators as an ideal accompaniment to a FTTP rollout, where for instance fiber optic is supplied direct to an apartment block and from there copper cable is used to supply residents with high-speed VDSL2.

1. What is NV-700I related products?


NV-700I can fully compatible with NV-700L.

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


Cause: Defective External power supply


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


Note: Please refer to power status table to check power input status. Section 3.3

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.

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

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

Verify that the proper cable type is used and its length does not exceed specified limits.

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

Make sure that the phone wire must be connecting NV-700I first, when powered on.

Replace the defective modem or cable if necessary.

• Or try to change band profile as 17a for getting long reach.


4. Line Link cannot be established.


  1. NV-700I Master/Slave setting failure or phone cable length is over the specification limit.
  2. Please make sure that the phone wire must be connected between NV-700I(Master) side and NV-700I(Slave) side when both are power on. NV-700I Master side will do link speed function depending on phone wire length, therefore if NV-700I Master side can’t detect Slave Side over phone wire while both power on, this will cause the Link to fail.
  3. Please check phone wire, we recommend use 24-26 gauge with twisted pair and without rust.
  4. Please reinsert power when change cable length or link time over 3 minutes.
Or try to change band profile as 17a for getting long reach.
  1. Note: Phone wire must meet CAT 3 standard or above and twisted pair, otherwise will cause more cross talk issue to reduce Line power driver.


5. What is VDSL2 technology? (Only reference)


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. Connected the NV-700I Master side with Slave side within 300 meters RJ-11 phone cable got only less than 10 Mbit/s.


We recommend to test NV-700I bandwidth best by Smartbit equipment, if you don't have Smartbit, we recommend test that by IPERF program, and TCP window size must be settled max. 64k, the parameter as iperf –c server IP address –i 1 –t 50 –w 65535 for client side.


7. I just bought a NV-700I to replace my Quest DSL modem for my home. I was told any VDSL2 modem would replace and give me higher communication speeds. It doesn’t get me internet when hooked up. All lights come on but no Link light. Is this the complete wrong application for this unit?
  1. Please note NV-700I is a Master (CO side), it must be connected to the NV-700I Slave(CPE side) to work. Band profile and band plan setting must be compatible to each other .
8. We need to set up a default gateway on a NV-700I 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(Line) or WAN(Line) 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 .
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. What can I do if I forgot my password.


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


10.What is the maximum Ethernet frame MTU for these modems?


NV-700I maximum Ethernet frame MTU is 2K bytes.
