VDSL2 Brief
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 at 'source' to symmetric 100 Mbit/s at 0.3 km and 50 Mbit/s 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+.
ADSL-like long reach (LR) performance: 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 2.5 km, gradually
increasing the bit rate up to symmetric 100Mbit/s as loop-length shortens. This means that VDSL2-based systems, unlike VDSL1
systems, are not limited to short loops or MTU/MDUs only, but can also be used for medium range applications.
MEG821AE
The MEG821AE utilize Lantiq(Infineon) Vinax VDSL2 Chipset, which is a MEG821AE that aggregates 8 ports into Giga Ethernet
uplinks for high-speed data/Internet services.
Based on DMT VDSL2 technologies, MEG821AE extends data service with line rate of solution for services such as remote lecturing,
Manual of VDSL2 Solution

telemedicine, video conferencing, Video-on-Demand (VoD), IP-TV, Internet access and other various high-speed data applications.
When the number of subscribers increases, the second uplink Giga Ethernet interface can be used to daisy chain to another
MEG821AE. Alternatively, multiple MEG821AE can be connected to another LAN switch to from a two-tier configuration, thus
supporting a lot more subscribers. The MEG821AE is an ideal solution for delivering cost-effective, high-performance broadband
/multimedia services to Multi-Tenant Units (MTUs) or Multi-Dwelling Units (MDUs) such as hotels, campus, hospitals and telecom.
The MEG821AE provides the important features necessary for robust networks.
Key features and benefits :
Jumbo packet up to 9k byte: In computer networking, jumbo frames are Ethernet frames with more than 1500 bytes of
payload. Conventionally, jumbo frames can carry up to 9000 bytes of payload, but variations exist and some care must be
taken when using the term.
The original 1500-byte payload size for Ethernet frames was used because of the high error rates and low speed of
communications. Thus, if one receives a corrupted packet, only 1500 bytes (plus 18 bytes for the frame header and other
overhead) must be re-sent to correct the error. However, each frame requires that the network hardware and software
process it. If the frame size is increased, the same amount of data can be transferred with less effort. This reduces CPU
utilization (mostly due to interrupt reduction) and increases throughput by allowing the system to concentrate on the data in
the frames.
IEEE 802.1q Q-in-Q VLAN for performance & security: The VLAN feature in the switch offers the benefits of both security
and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the
broadcast traffic to within the same VLAN broadcast domain also enhances performance. VLAN support enabling advanced
techniques such as 802.1Q-in-1Q to be deployed.
And support GVRP up to 4k V-Lan groups.

IEEE 802.1x: Port base network access control, this function for wireless users connecting Authentication.
Spanning tree: Support IEEE 802.1d STP/IEEE 802.1w RSTP/IEEE-802.1s MSTP. For mission critical environments with
multiple switches supporting STP, you can configure the switches with a redundant backup bridge path, so transmission and
reception of packets can be guaranteed in event of any fail-over switch on the network.
IEEEE 802.1p QoS(COS) with Four Priority Queues:
The QoS(Quality Of Service) feature provides four internal queues to support four different classifications of
traffic. High priority packet streams experience less delay inside the switch, which supports lower latency for
certain delay-sensitive traffic. The MEG821AE can classify the packet as one of the 8-level priority to 4 –level
queue mapping. I.e. Highest, SecHigh, Lowest, SecLow.
Differentiated Services or DiffServ: is a computer networking architecture that specifies a simple, scalable and
coarse-grained mechanism for classifying, managing network traffic and providing Quality of Service (QoS) on
modern IP networks. DiffServ can, for example, be used to provide low-latency to critical network traffic such as
voice or streaming media while providing simple best-effort service to non-critical services such as web traffic or
file transfers.
DiffServ uses the 6-bit Differentiated Services Code Point (DSCP) field in the IP header for packet
classification purposes. DSCP replaces the outdated Type of Service field.
IGMP Snooping : Snooping by 256 IP multicast table for VOD (Video on demand) and Video conference and Internet games
application.

HTTPS (SSL) Web Access: Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer
Protocol with the SSL protocol to provide encrypted communication and secure identification of a network web
server. HTTPS connections are often used for payment transactions on the World Wide Web and for sensitive
transactions in corporate information systems.
SNMP MIB Support: SNMP v1/v2c/v3 management and trap function
Support MIB tables: MIB-II (RFC 1213), Bridge MIBs (RFC 1493), Ethernet-like MIB (RFC 1643 & RFC 2665), private-MIB,
USM-MIB (RFC 2574), VACM-MIB (RFC 2575) and RMON-MIB 1, 2, 3, 9 groups (RFC 1757& RFC 2819).
Broadcast/Multicast/Unknown-unicast Storm Control:To limit too many broadcast/multicast/unknown-unicast flooding
in the network, broadcast/multicast storm control is used to restrict excess traffic. Threshold values are available to control
the rate limit for each port. Packets are discarded if the count exceeds the configured upper threshold.
Port Mirroring: This function could be mirroring and duplicated client side action, but Need to be with mirroring AP as
Session wall or other.
ACL(Access Control List): On some types of proprietary computer hardware, an Access Control List refers to rules that
are applied to port numbers or network daemon names that are available on a host or other layer 3, each with a list of hosts
and/or networks permitted to use the service. Both individual servers as well as routers can have network ACLs. Access
control lists can generally be configured to control both inbound and outbound traffic, and in this context they are similar to
firewalls. Like Firewalls, ACLs are subject to security regulations and standards.
Link Layer Discovery Protocol (LLDP): is a vendor-neutral Link Layer protocol in the Internet Protocol Suite used by
Manual of VDSL2 Solution
http://www.black-box.eu
6
network devices for advertising their identity, capabilities, and neighbors on a IEEE 802 local area network, principally wired
Ethernet. The protocol is formally referred to by the IEEE as Station and Media Access Control Connectivity Discovery
specified in standards document IEEE 802.1AB.
Speed Rate Control: Supports speed rate control function from 128k to 100Mbps.
Note: Regarding our MEG821AE' principle of bandwidth control, which must rely on flow control to limit
bandwidth over hardware, as long as client side doesn't support flow control, the upstream bandwidth control is
invalid, so for this case, client side must support flow control function.
In band Management: Provides a console port for setup IP or other function
Out Of Band Management: Supports remote control by Telnet and Web-based Management easy-to-use configuration and
ongoing monitoring. This software is embedded in the switch and delivers remote, intuitive management of the switch and
connected NIC devices through a single IP address. The VDSL2 8Ports Switch are easy-to-configured and deployed, and
offering a compelling option in terms of cost, performance, scalability and services compared to traditional repeater HUB
solutions.
2 Dual Media for Flexible Fiber Connection:Dual media port 9 and 10 are provided for flexible fiber/copper auto link
connection. You can select to install optional transceiver modules in these slots for short, medium or long distance fiber
backbone attachment. Use of the SFP will auto disable their corresponding built-in 10/100/1000Base-T connections.
DHCP Client: Dynamic Host Configuration Protocol (DHCP) for auto configuration management IP.
TFTP Protocol: Trivial File Transfer Protocol(TFTP) for new version firmware remote upgraded
Manual of VDSL2 Solution
http://www.black-box.eu
7
Firmware upgrade support : HTTP / TFTP protocol.
Scalability: Up to 100 Mbps symmetric performance over single-pair wiring for VDSL2 Channel
port aggregation.
Interleave delay time: To prevent the transmission against burst errors.
Noise Margins(SNRM): In electrical engineering, noise margin is the amount by which a signal exceeds the minimum
amount for proper operation. MEG821AE default value is 6db for telecom standard.
Upstream Power Back-Off (UPBO): helps to run services over loops with different
length co-located in the same cable binder (“mixed length” deployments), especially
in FEXT-dominated noise environment.
Strong FEXT generated by short loops can significantly degrade the performance
of long loops if UPBO is not applied. On the other hand, UPBO reduces the transmit
power of short loops and thus degrades their performance as well. The UPBO
technique should take in account both issues.
Downstream Power Back-Off (DPBO): The development of Triple Play services requires higher bandwidth. Higher
bandwidth and substantial performance gain can be reached by deploying DSLAM-s in a remote side cabinet near to the
customer premises. There is no problem at clean networks where all the customers are connected to the same local cabinet.

Single-Ended Loop Testing (SELT) : The most convenient tests to perform are those that only require connection to one end
of the line, because only one tester is required, and one person is required, and no travelling needs to be done. Some tests
require the line to be correctly terminated and it may be possible to set the installed equipment (eg modem) to do this without
having to go to the end of the line.
Double-Ended Loop Testing (DELT) : Double-ended testing involves dispatching a technician to the customer's location to
install a modem or test equipment that communicates with the reference modem in the CO. If the service doesn't work, a work
order is issued to clean up the pair.
Trellis modulation : The name trellis was coined because a state diagram of the technique, when drawn on paper closely
resembles the trellis lattice used in rose gardens. The scheme is basically a convolutional code of rates (r,r+1). Ungerboeck's
unique contribution is to apply the parity check on a per symbol basis instead of the older technique of applying it to the bit
stream then modulating the bits. The key idea he termed Mapping by Set Partitions. This idea was to group the symbols in a
tree like fashion then separate them into two limbs of equal size. At each limb of the tree, the symbols were further apart.
Although in multi-dimensions, it is hard to visualize, a simple one dimension example illustrates the basic procedure. Suppose
the symbols are located at [1, 2, 3, 4, ...]. Then take all odd symbols and place them in one group, and the even symbols in the
second group. This is not quite accurate because Ungerboeck was looking at the two dimensional problem, but the principle is
the same, take every other one for each group and repeat the procedure for each tree limb. He next described a method of
assigning the encoded bit stream onto the symbols in a very systematic procedure. Once this procedure was fully described,
his next step was to program the algorithms into a computer and let the computer search for the best codes. The results were
astonishing. Even the most simple code (4 state) produced error rates nearly 1,000 times lower than an equivalent uncoded
system. For two years Ungerboeck kept these results private and only conveyed them to close colleagues. Finally, in 1982,
Manual of VDSL2 Solution
http://www.black-box.eu

Ungerboeck published a paper describing the principles of trellis modulation.
A flurry of research activity ensued, and by 1990 the International Telecommunication Union had published modem standards
for the first trellis-modulated modem at 14.4 kbit/s (2,400 baud and 6 bits per symbol). Over the next several years further
advances in encoding, plus a corresponding symbol rate increase from 2,400 to 3,429 baud, allowed modems to achieve rates
up to 34.3 kbit/s (limited by maximum power regulations to 33.8 kbit/s). Today, the most common trellis-modulated V.34
modems use a 4-dimensional set partition which is achieved by treating two 2-dimensional symbols as a single lattice. This set
uses 8, 16, or 32 state convolutional codes to squeeze the equivalent of 6 to 10 bits into each symbol sent by the modem (for
example, 2,400 baud × 8 bits/symbol = 19,200 bit/s).
Once manufacturers introduced modems with trellis modulation, transmission rates increased to the point where interactive
transfer of multimedia over the telephone became feasible (a 200 kilobyte image and a 5 megabyte song could be downloaded
in less than 1 minute and 30 minutes, respectively). Sharing a floppy disk via a BBS could be done in just a few minutes,
instead of an hour. Thus Ungerboeck's
Echo cancellation : The term echo cancellation is used in telephony to describe the process of removing echo from a voice
communication in order to improve voice quality on a telephone call. In addition to improving subjective quality, this process
increases the capacity achieved through silence suppression by preventing echo from traveling across a network.
Two sources of echo have primary relevance in telephony: acoustic echo and hybrid echo.
Echo cancellation involves first recognizing the originally transmitted signal that re-appears, with some delay, in the transmitted
or received signal. Once the echo is recognized, it can be removed by 'subtracting' it from the transmitted or received signal.
This technique is generally implemented using a digital signal processor (DSP), but can also be implemented in software. Echo
cancellation is done using either echo suppressors or echo cancellers, or in some cases both.
INP(Impulse Noise Protection): Impulse noise in multicarrier communication systems behaves effectively as a modulating
Manual of VDSL2 Solution
http://www.black-box.eu

signal that controls the first moment of the background Gaussian noise. The composite noise, which is the aggregate of the
Gaussian noise and impulse noise, has a probability density function that is conditionally Gaussian with non-zero average,
hence referred to as biased-Gaussian. The BER-equivalent power of the composite noise source is defined as the power of a
pure Gaussian noise source that yields the same bit-error rate (BER). The BER-equivalent noise for a biased-Gaussian noise
is simply the amplified version of the underlying Gaussian noise source. The amplification factor is derived from the
characteristics of the impulse interference. Any bit-loading algorithm designed for Gaussian noise sources is also applicable to
biased-Gaussian noise sources provided that the BER-equivalent SNR is used in place of the measured SNR.
Syslog : is a standard for logging program messages. It allows separation of the software that generates messages from the
system that stores them and the software that reports and analyzes them. It also provides devices which would otherwise be
unable to communicate a means to notify administrators of problems or performance.
Syslog can be used for computer system management and security auditing as well as generalized informational, analysis,
and debugging messages. It is supported by a wide variety of devices (like printers and routers) and receivers across multiple
platforms. Because of this, syslog can be used to integrate log data from many different types of systems into a central
repository.

First, make sure fiber to fiber connecting is ready, and then the VDSL2 8PORTS SWITCH will be sensing and link that in Fiber optic
mode.
GIGA port RJ-45 and SFP can’t use in the same time, else that will be link in Copper mode (default).
2.3 SFP Fiber Optics
A gigabit interface converter (SFP) is a transceiver that converts electric currents (digital highs and lows) to optical signals, and
optical signals to digital electric currents. The SFP is typically employed in fiber optic and Ethernet systems as an interface for
high-speed networking. The data transfer rate is 1.25 gigabit per second.
SFP modules allow technicians to easily configure and upgrade electro-optical communications networks. The typical SFP
transceiver is a plug-in module that supports hot-plugging (it can be removed and replaced without turning off the system).
The devices are economical, because they eliminate the necessity for replacing entire boards at the system level. Upgrading
can be done with any number of units at a time, from an individual module to all the modules in a system. SFP (Small Form
Pluggable Transceivers), meet the Gigabit Interface Converter specification Rev. 5.4 (MOD_DEF4) industry standard.

Chapter 3. Installation
3.1 Hardware Installation
This chapter describes how to install the VDSL2 8PORTS SWITCH and establish network connections. You may install this
VDSL2 8PORTS SWITCH on any level surface (table, shelf, 19 inch rack or wall mounting). However, please take Note of the
following minimum site requirements before you begin.
4 plastic feet on the bottom has been pre-installed.
3.2 Pre-Installation Requirements
Before you start actual hardware installation, make sure you can provide the right operating environment, including power
requirements, sufficient physical space, and proximity to other network devices that are to be connected. Verify the following
installation requirement:
Power requirements: AC 100V to 240 V at 50 to 60 Hz.
The VDSL2 8PORTS SWITCH power supply automatically adjusts to the input voltage level.
The VDSL2 8PORTS SWITCH should be located in a cool dry place, with at least 10cm/4in of space at the front and back
for ventilation.
Place the VDSL2 8PORTS SWITCH out of direct sunlight, and away from heat sources or areas with a high amount of
electromagnetic interference.
Check if network cables and connectors needed for installation are available.

3.3 General Rules
Before making any connections to the VDSL2 8PORTS SWITCH, Note the following rules:
Ethernet Port (RJ-45)
All network connections to the VDSL2 8PORTS SWITCH Ethernet port must be made using Category 5
UTP for 100Mbps and Category 3,4 UTP for 10Mbps.
No more than 100 meters (about 328 feet) of cabling may be used between the VDSL2 8PORTS SWITCH and an end
node.
3.4 Connection Configuration
The VDSL2 8PORTS SWITCH has 8 100 Mbps VDSL2 ports. And 2 Giga Ethernet ports which support connection to
10/100/1000 Ethernet. Support full or half-duplex operation and Auto MDI/MDIX. The transmission mode is using
auto-negotiation. Therefore, the devices attached to these ports must support auto-negotiation unless they will always operate
at half duplex. If transmissions must run at full duplex, but the attached device does not support auto-negotiation, then you
should upgrade this device to a newer version that supports auto-negotiation.
Use any of the 9~10 ports to connect to devices such as a workstation, server, bridge or router. You can also cascade to another
compatible VDSL2 8PORTS SWITCH or hub by connecting an MDI or MDIX port.
1.You can connect an (9~10) station port on the VDSL2 8PORTS SWITCH to any device that uses a standard network interface
such as a optical fiber converter, workstation or server, or also to a network interconnection device such as a bridge or router
(depending on the port type implemented).
2.Prepare the network devices you wish to network. Make sure you have installed VDSL2 CPE Modem making a connection to
any of the VDSL2 8PORTS SWITCH (1~8) station ports. You also need to prepare 24~26 gauge phone wire with RJ11 plugs

at both ends.
3.Connect one end of the cable to the RJ-45 port of the network interface card, and the other end to any available (9~10) station
port on the VDSL2 8PORTS SWITCH. Every port support either 10 /100/1000 Mbps connections. When inserting an RJ-45
plug, be sure the tab on the plug clicks into position to ensure that it is properly seated.
Note:
1. Be sure each twisted-pair cable (RJ-45) is not over by 100 meters (328 feet).
2. We advise using Category 5 cable for Cable Modem or router connections or to attach to any high bandwidth device to avoid
any confusion or inconvenience.
