2.3 General Rules

Before making any connections to the router, please note the following rules:

• Ethernet Port (RJ-45)

All network connections to the router Ethernet port must be made using Category 5 UTP/STP or above for 100 Mbps, Category 3, 4 UTP for 10Mbps. No more than 100 meters of cabling may be use between the MUX or HUB and an end node.

• VDSL2 Port (RJ-11)

All network connections to the RJ-11port must use 24~26 gauge with twisted pair phone wiring. We do not recommend the use of the telephone line 28 gauge or above. The RJ-11 connectors have six positions, two of which are wired. The router uses the center two pins. The

pin out assignment for these connectors is presented below.

Please note that the line port is no polarity, therefore user can reverse the two wires of the phone cable

when installed.

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

2.4 Connecting the Router

The router has four Ethernet ports which support connection to Ethernet operation. The devices attached to these ports must support auto-negotiation /10Base-T / 100Base-TX unless they will always operate at half duplex. Use any of the Ethernet ports to connect devices such as Monitor systems, Servers, Switches, bridges or routers.

Notes:

1. The (RJ11) Line port is used to connect the telephone that is connected to VDSL2 CO and CPE router (Point-to-point solution).

2. The Slave device (CPE) must be connected to the Master device (CO) through the telephone wire. The Slave cannot be connected to another Slave, and the Master cannot be connected to another Master.

Page 11

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

2.5 Connecting the RJ-11 / RJ-45 Ports

 The line port has 1 connector: RJ-11. It is used to connect with NV-700L(CO) using a single pair phone cable to NV-720R(CPE)

bridge side (point to point solution). (Figure 2.1)

 When inserting a RJ-11 plug, make sure the tab on the plug

clicks into position to ensure that it is properly seated.

 Do not plug a RJ-11 phone jack connector into the Ethernet

port (RJ-45 port). This may damage the router. Instead, use only twisted-pair cables with RJ-45 connectors that conform to Ethernet standard.

Notes:

Be sure each twisted-pair cable (RJ-45 Ethernet cable) does not exceed 100 meters (333 feet).

We advise using Category 5~7 UTP/STP cables for making Bridge or Router connections to avoid any confusion or inconvenience in the future when you attach high bandwidth devices.

Use 24 ~ 26 gauge twisted pair phone wiring, we do not recommend 28 gauge or above.

Be sure phone wire has been installed before the NV-720R boot.

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

 2.6.1 Connect the NV-802S and the NV-720R to the Line

The objective for VDSL2 is to pass high speed data over a twisted pair cable. In the setup, connect NV-802S to NV-720R through phone wire(24~26 AWG) or line simulator or any other hardware representation of a cable network, with or without noise injection and crosstalk simulations.

 2.6.2 Connect the NV-802S and the NV-720R to LAN Devices

In the setup, usually an Ethernet tester serves as a representation of the LAN side as well as a representation of the WAN side.

 2.6.3 Run Demos and Tests

The Ethernet tester may send data downstream as well as upstream. It also receives the data in order to check the integrity of the data transmission. Different data rates can be tested under different line conditions.

Before user installed power and device, please read and follow these essentials:



Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.

Note:

Do not run signal or communications wiring and power wiring through the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.



You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring sharing similar electrical characteristics can be bundled together.



You should separate input wiring from output wiring.



We recommend that you mark all equipment in the wiring system.

Troubleshooting

Diagnosing the Router’s Indicators

The router can be easily monitored through its comprehensive panel indicators. These indicators assist the network manager in identifying problems the hub may encounter. This section describes common problems you may encounter and possible solutions.

1. Symptom: 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

2. Symptom: Link indicator does not light up (green) after making a connection.

Cause:

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

Solution:

2.1 Power off and re-power on the VDSL2 router.

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

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

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

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

2.6 Make sure that the phone wire must be connecting NV-720R first, when powered on.

2.7 Replace the defective router or cable if necessary.

Page 54

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

3. Symptom: VDSL Link cannot be established.

Cause: VDSL setting failure or phone cable length is over the specification limit.

Solution:

3.1 Please make sure that the phone wire must be connected between CO side and NV-720R (CPE) when both are power on. CO side will do link speed function depending on phone wire length, therefore if CO side can’t detect NV-720R (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.

Note:

Phone wire must meet CAT 3 standard or above and without clustering, otherwise will cause more cross talk issue to reduce DSL power driver.

4. Question: What is VDSL2? (Only reference)

Answer:

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.

Page 55

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

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.

5. Question: What is SNR(Signal-to-Noise)? (Only reference)

Answer:

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

Page 56

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

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.

6. Symptom:

Connected the CO Router with CPE Router within 300 meters RJ-11 phone cable got only less than 10 Mbit/s.

Cause:

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.

Solution:

We recommend to test VDSL2 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. Question:

I just bought a Netsys NV-720R

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?

Page 57

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

Answer:

Re: Please note NV-720R is a remote side(CPE side), it must be connected to the CO side to work.

Tone mode, Band profile and band plan setting must be compatible to each other if not access error will show when applied. Please deactivate and activate once the setting has been changed.

8. Question:

We need to set up a default gateway on a NV-720 pair which are in Bridge mode, as they want to manage the units from a different network.

Answer:

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 . 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. Question: Is it possible to use ADSL2 IP DSLAM with the NV-720R?

Answer:

NV-720R support the ADSL backward compatible, therefore the NV-720R can connect to ADSL2 IP DSLAM(Annex B).

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

10. Question: What can I do if I forgot my password.

Answer:

If you forgot your password, you must reset your router. Unfortunately this process will change all your

settings back to the factory defaults.

To reset the router, locate the reset 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 192.168.16.254. When logging in, the default username and password both are “admin”.

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

Answer: NV-720R maximum Ethernet frame MTU is 1536 bytes(Jumbo Frame).

System Diagnostics

Power and Cooling Problems

If the POWER indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply as explained in the previous section. However, if the unit power is off after running for a while, check for loose power connections, power losses or surges at the power outlet. If you still cannot isolate the problem, then the internal power supply may be defective. In this case, please contact your local dealer.

Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g. the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

Transmission Mode

The default method of selecting the transmission mode for RJ-45 ports is 10/100 Mbps ETHERNET, for RJ-11 port are auto-negotiation VDSL. Therefore, if the Link signal is disrupted (e.g. by unplugging the network cable and plugging it back in again, or by resetting the power), the port will try to reestablish communications with the attached device via auto-negotiation. If auto-negotiation fails, then communications are set to half duplex by default. Based on this type of commercial-standard connection policy, if you are using a full-duplex device that does not support auto-negotiation, communications can be easily lost (i.e. reset to the wrong mode) whenever the attached device is reset or experiences a power fluctuation. The best way to resolve this problem is to upgrade these devices to a version that support Ethernet and VDSL.

Physical Configuration

If problems occur after altering the network configuration, restore the original connections, and try to track the problem down by implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of the installation do not exceed recommendations.

System Integrity

As a last resort verify the switch integrity with a power-on reset. Turn the power to the switch off and then on several times. If the problem still persists and you have completed all the preceding diagnoses, then contact your dealer.
