Foreword: VDSL2 Point to Point Solution

VDSL2 (Very-High-Bit-Rate Digital Subscriber Line 2, ITU-T G.993.2 Standard) is an access
technology that exploits the existing infrastructure of copper wires that were originally deployed for
POTS services. It can be deployed from central offices, from fibre-fed cabinets located near the
customer premises, or within buildings.

ITU-T G.993.2 VDSL2 is the newest and most advanced standard of 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 enables operators
and carriers to gradually, flexibly, and cost efficiently upgrade existing xDSL-infrastructure.

ITU-T G.993.2 (VDSL2) is an enhancement to G.993.1 VDSL that permits the transmission of
asymmetric and symmetric(Full-Duplex) aggregate data rates up to 200 Mbit/s on twisted pairs
using a bandwidth up to 30 MHz.

VDSL2 deteriorates quickly from a theoretical maximum of 200 Mbit/s (Full-Duplex) at “source” to
100 Mbit/s at 0.3 km (symmetric) and 50 Mbps at 1 km, but degrades at a much slower rate from
there and still outperforms VDSL. Starting from 1.6 km its performance is equal to ADSL2+.

Attention:
Be sure to read this manual carefully before using this product. Especially Legal Disclaimer,

Chapter 5. Building a VDSL2 System

First a quick overview on a complete setup of VC-400LT/R:

Figure 6 VDSL2 Application

5.1 Connect the VC-400LT and the VC-400RT+ to the Line

The objective for VDSL2 is to pass high speed data over a twisted pair cable. In the
setup, connects VC-400LT to VC-400RT+ through phone wire or line simulator or
any other hardware representation of a cable network, with or without noise injection
and crosstalk simulations.

5.2 Connect the VC-400LT and the VC-400RT+ to LAN Devices

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

5.3 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.

VC-400LT/RT+ VDSL2 CO&CPE Router MANUAL Ver.B3

Chapter 6. Operating the VDSL2 System

After the VDSL2 system has been set up, one may want to configure the settings that
are related to VDSL2.
Configuration of operation modes, test modes (loop back) and the display of status
information are supported by GUI (Graphical User Interface).

6.1 Configuration Settings

Configure and start the VC-400LT (CO) and the VC-400RT+ (CPE).

 Configuration: As a minimum configuration, usually selecting the bandplan is

required.

See Section 7.1.3, Profile Configuration.

 Next, both sides should be activated from the web interface.

See Section 7.1.6, Line Activation

 The connection status of the link can be monitored.

See Section 7.2.1, Line Status

6.1.1 Channel Configuration
This function is for setting VDSL2 channel.

Figure 6.1.1 Channel Configuration Menu

Interleave delay function is used in digital data transmission technology to protect the
transmission against noise issue and data error.

If during transit more than a certain amount of data has been lost then the data cannot
be correctly decoded. Short bursts of noise on the line can cause these data packets
to become corrupt and the router has to re-request data which in turn can slow down
the overall rate at which data is transmitted.

VC-400LT/RT+ VDSL2 CO&CPE Router MANUAL Ver.B3

19

Interleaving is a method of taking data packets, chopping them up into smaller bits and
then rearranging them so that once contiguous data is now spaced further apart into a
non continuous stream. Data packets are re-assembled by your router.

The diagram below is an example of how interleaved traffic is transmitted.

If your line is particularly susceptible to bursts of noise then interleaving should
improve your VDSL2 experience simply because if you lose a whole batch of data then
this could cause your router to loose sync with the exchange.

Using Interleaving, the router is able to re-assemble the data or if necessary just
re-request the part of the data that it is unable to recover. By increasing the interleave
depth of each ports that are susceptible to noise, this will improve error performance
and stability of marginal lines.

Channel Configuration Settings

Setting Description

Channel Number

To which bearer channel number shall the settings apply?

 Channel 0

Direction

To which direction shall the settings apply?

 Upstream
 Downstream

Min Data Rate Minimum Payload Data Rate
Max Data Rate Maximum Payload Data Rate
Max Interleave Delay Maximum Interleave Delay (set from 0 to 255ms)

Note:

1.Regarding the interleave delay value time function for anti-noise purpose, due to the noise of
each environment are different, so you could adjust interleave delay value when filed
environment has heavy noise. Please note that increase interleave delay time will reduce few
vdsl2 bandwidth and depond on interleave delay time.

2. The Min and Max Data Rate function similar rate control function, you can limit rate for the

VDSL2 port.

3. Please note you must deactivate then activate once on config port when you config

VDSL2 arguments.

6.1.2 Line Configuration

Figure 6.1.2 Line Configuration Menu for SNR Margin Selection

Line Configuration

Setting Description
Direction Select the target direction.

Target SNRM

Set the required SNR Margin *10
(60=6dB)

Note:
Noise Margin is the non-technical term for Signal to Noise Ratio Margin (SNRM). Domestic
standard modems and VDSL2 routers often use the terms Noise Margin or SNR when reporting on
its value. The Signal to Noise Ratio, as its name implies, is the ratio between the strength of the
signal and the level of noise on the line.
That ratio is a major factor in determining the connection speed, as the higher the ratio the higher
the possible speed. The SNRM is a margin which by which the noise level can rise before
connection is lost.
Taking the default (target) value of 6 dB applied is follow up telecom standard. Basically, you don't
need adjust this value.

6.1.3 Profile Configuration

For this function, VC-400LT/R provides world wide telecom standard band plan, such
as meet European telecom standard band plan 998(17a), USA telecom standard band
plan 997(8a, 8b) and APAC Telecom standard band plan (30a) etc.

 Annex A specifies bandplans for the North American region and enables VDSL2

ROUTER to be deployed with traditional POTS telephony or in an all-digital
mode.

 Annex B specifies bandplans for Europe and enables VDSL2 ROUTER

VC-400LT/RT+ VDSL2 CO&CPE Router MANUAL Ver.B3

21

deployment with underlying POTS and ISDN services.

 Annex C allows VDSL2 ROUTER to coexist with TCM-ISDN services, found

primarily in APAC.

VC-400RT+whas numerous configuration profiles and bandplans to meet regional
service provider requirements. The frequency bandwidth has increased to 30 MHz,
with configuration options at 8.5 MHz, 12 MHz, 17.7 MHz and 30 MHz.

Band profile and band plan can only be configured at VC-400LT as VC-400RT+ will
auto-follow up on the settings of VC-400LT. The only thing that VC-400RT+ must be
configured so that the routers will link is the tone mode. However, the default tone
mode for VC-400LT/R is V43, so at default there’s no need to change the tone mode
unless it is required by the telecom companies to use different tone mode. Another
important thing is that 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.

Figure 6.1.3.1 VC-400LT Profile Configuration

 Please note you must deactivate then activate once on config port when

you config VDSL2 arguments.

test being done at one station and the two lines interconnected at the distant station.
Commonly called loop around when the interconnecting circuit is accessed by dialing.

 A patch cable, applied manually or automatically, remotely or locally, that facilitates a

loop-back test.

 A communication channel with only one endpoint. Any message transmitted through such

a channel is immediately received by the same channel.

6.2.5 BitsGraphs

When VC-400LT link with VC-400RT+ , this graph will show the bits value for each tone.

Figure 6.2.5 Display Bits Per Tone Graph

Regarding the describe of "tone graph"(Only reference):

"If slow service is indicated, technicians can look at the bits per tone measurement. Dips in the bit
per tone graph indicate interference. Checking the frequency of the interference often makes it
possible to identify its cause. The accompanying chart shows the frequencies associated with
common interference sources, such as T1,E1 and HDSL. If the bits per tone are taking a hit and it is
determined that noise is not the cause, then the cause could be a DC fault, such as a bridge tap or
a wet section. Very low or nonexistent bits per tone in the high frequency band indicate the
presence of a long loop. If there is a major dip in the bits-per-tone graph but the noise
power-per-tone graph does not show any abnormalities, the most likely troubles are bridged taps or

VC-400LT/RT+ VDSL2 CO&CPE Router MANUAL Ver.B3

31

wet sections on the span. Use a loop-troubleshooting tool with a TDR to find and fix these problems.
If the bits per tone are low across the whole bandwidth, the cause is most likely DC troubles on the
loop, such as shorts or grounds. A major dip in bits per tone indicates AC trouble on the loop. To
verify the type of AC trouble, compare the bits per tone to SNR. If the noise influence and
bits-per-tone dip occur at the same frequency, the degraded performance is most likely due to a
transmission influence. The particular frequency will help identify the source of influence or
crosstalk.

Chapter 7. Configuration Interface of the Router

This section explains how to configure the router section of the VC-400LT/R using its
web-based configuration.

The part of the circuitry as well as the router configuration menu has been

“adm0”. It supports four Ethernet connections.

 The IP addresses are used in this chapter are different from the examples in

the previous chapters.

 The password used in this chapter is different from the examples in the

previous chapters.



Appendix B: Troubleshooting

1. 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.

2. Symptom:

VDSL2 CO router cannot link with CPE router.

Cause:

1. The VDSL2 CO/CPE mode settings of VDSL2 router become unknown.

2. VDSL2 CO and CPE router tone mode is different due to mixed use of new
and old hardware VDSL2 routers.

Solution:

1. Using the console, reboot the system and go to loader menu. Select set boot

parameters and select the VDSL2 CO/CPE mode correctly. Select “1” if it is CO
router and “0” if it is CPE router. Do not just press enter to skip the setting as it
will not retain even if the setting is correct, then it will become unknown causing
the VDSL2 router not to link. 1: VC-400LT. 0: VC-400RT+ .

2. Update the old hardware to D series firmware so that you can set the same

tone mode for both CO and CPE router.

3. Symptom: VDSL2 web management that uses public IP address cannot be accessed.

Cause:

It can be affected by some incoming traffic perhaps web crawlers, worms or
other automated activity.

Solution:

Open a command prompt and log in to telnet by writing “telnet xxx.xxx.xxx.xxx”,
xxx is the IP address of your router, then write “cd /etc/rc.d/init.d” to go to this
folder, then write “./httpd start” to open the web management, so that it can be
accessed again.

Appendix C: Cable Requirements

A CAT 3, 4 or 5 UTP (unshielded twisted pair) cable is typically used to connect the
Ethernet device to the modem. A 10Base-T cable often consists of four pairs of wires, two
of which are used for transmission. The connector at the end of the 10Base-T cable is
referred to as an RJ-45 connector and it consists of eight pins. The Ethernet standard uses
pins 1, 2, 3 and 6 for data transmission purposes. (Table C-1)
