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 quic ly from a theoretical maximum of 200 Mbit/s at 'source' to symmetric 100 Mbit/s at 0.3 m and 50 Mbit/s at
1 m, but degrades at a much slower rate from there, and still outperforms VDSL. Starting from 1,6 m its performance is equal to
ADSL2+.
ADSL-li e long reach (LR) performance: ADSL-li e long reach performance is one of the ey advantages of VDSL2. LR-VDSL2
enabled systems are capable of supporting speeds of around 1-4 Mbit/s (downstream) over distances of 2.5 m, gradually increasing
the bit rate up to symmetric 100Mbit/s as loop-length shortens. This means that VDSL2-based systems, unli e VDSL1 systems, are
not limited to short loops or MTU/MDUs only, but can also be used for medium range applications.

VDSL2 IP DSLAM
The NV-2400H is a VDSL2 IP DSLAM that aggregates 24 ports into Giga Ethernet uplin s for high-speed data/Internet services.
Based on DMT VDSL2 technologies, NV-2400H extends data service with line rate of solution for services such as remote lecturing,
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 uplin Giga Ethernet interface can be used to daisy chain to another
NV-2400H. Alternatively, multiple NV-2400H can be connected to another LAN switch to from a two-tier configuration, thus
supporting a lot more subscribers. The NV-2400H 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
sscom.
The NV-2400H provides the important features necessary for robust networ s
Key features and benefits :
 Jumbo packet up to 9k bytes: In computer networ ing, 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
ta en 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 pac et, 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 networ 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 4 V-Lan groups.
 IEEE 802.1x: port base networ 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 bac up bridge path, so transmission and
reception of pac ets can be guaranteed in event of any fail-over switch on the networ .
 IEEEE 802.1p QoS( OS) with Four Priority Queues:
The QoS(Quality Of Service) feature provides four internal queues to support four different classifications of
traffic. High priority pac et streams experience less delay inside the switch, which supports lower latency for
certain delay-sensitive traffic. The NV-2400H can classify the pac et 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 networ ing architecture that specifies a simple, scalable and
coarse-grained mechanism for classifying, managing networ traffic and providing Quality of Service (QoS) on
modern IP networ s. DiffServ can, for example, be used to provide low-latency to critical networ 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 ode Point (DS P) field in the IP header for pac et
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 networ 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-li e 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 ontrol: To limit too many broadcast/multicast/un nown-unicast flooding
in the networ , broadcast/multicast storm control is used to restrict excess traffic. Threshold values are available to control
the rate limit for each port. Pac ets are discarded if the count exceeds the configured upper threshold.
 A L(Access ontrol List): On some types of proprietary computer hardware, an Access ontrol List refers to rules that
are applied to port numbers or networ daemon names that are available on a host or other layer 3, each with a list of hosts
and/or networ s permitted to use the service. Both individual servers as well as routers can have networ ACLs. Access
control lists can generally be configured to control both inbound and outbound traffic, and in this context they are similar to
firewalls. Li e Firewalls, ACLs are subject to security regulations and standards.

 Link Layer Discovery Protocol (LLDP): is a vendor-neutral Lin Layer protocol in the Internet Protocol Suite used by
networ devices for advertising their identity, capabilities, and neighbors on a IEEE 802 local area networ , 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 ontrol(Traffic shaping): Supports speed rate control function from 128 to 100Mbps.
Note:
Regarding our NV-2400H's 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(RJ45 to D-Sub 9Pin) 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 NV-2400H 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 onnection:Dual media port 9 and 10 are provided for flexible fiber/copper auto lin
connection. You can select to install optional transceiver modules in these slots for short, medium or long distance fiber
bac bone attachment. Use of the SFP will auto disable their corresponding built-in 10/100/1000Base-T connections.
 DH P lient: Dynamic Host Configuration Protocol (DHCP) for auto configuration management IP.
 TFTP Protocol: Trivial File Transfer Protocol(TFTP) for new version firmware remote upgraded
 Firmware upgrade support : HTTP / TFTP protocol.

 Scalability: Up to 100 Mbps symmetric performance over single-pair wiring for VDSL2 Channel.
 Interleave delay time: To prevent the transmission against burst errors. Please note that enable interleave delay
function will reduce a few vdsl2 bandwidth.
 Noise Margin(SNRM): In electrical engineering, noise margin is the amount by which a signal exceeds the minimum
amount for proper operation. NV-2400H default value is 6db for telecom standard.
 INP(Impulse Noise Protection): Impulse noise in multicarrier communication systems behaves effectively as a modulating
signal that controls the first moment of the bac ground 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 (li e 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.
