Chapter 3 Configuration
3.1 Determine your connection settings
Before you configure the router, you need to know the connection information
supplied by your VDSL2 service provider.
3.2 Connecting the VDSL2 Router to your network
Unlike a simple hub or switch, the setup of the VDSL2 Router consists of more than
simply plugging everything together. Because the Router acts as a DHCP server, you
will have to set some values within the Router, and also configure your networked
PCs to accept the IP Addresses the Router chooses to assign them.
Generally there are several different operating modes for your applications. And you
can know which mode is necessary for your system. These modes are router, bridge.

3.5.8 UPnP
UPnP (Universal Plug and Play) is a distributed, open networking standard that uses
TCP/IP for simple peer-to-peer network connectivity between devices. An UPnP
device can dynamically join a network, obtain an IP address, convey its capabilities
and learn about other devices on the network. In turn, a device can leave a network
smoothly an automatically when it is no longer in use. UPnP broadcasts are only
allowed on the LAN.
How do I know if I'm using UPnP?
UPnP hardware is identified as an icon in the Network Connections folder (in Windows
XP & Windows ME). Each UPnP-compatible device that is installed on your network
will appear as a separate icon.
The UPnP settings can be viewed in the left navigation bar. The following are the

4.1.2 Line Configuration
If the incoming signal strength in microvolts is Vs, and the noise level, also in
microvolts, is Vn, then the signal-to-noise ratio, S/N, in decibels is given by the
formula
S/N = 20 log10 (Vs/Vn)
If Vs = Vn, then S/N = 0. In this situation, the signal borders on unreadable, because
the noise level severely competes with it. In digital communications, this 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.
Ideally, Vs is greater than Vn, so S/N is positive. As an example, suppose that Vs =
10.0 microvolts and Vn = 1.00 microvolt. Then
S/N = 20 log10 (10.0) = 20.0 dB
This results in the signal being clearly readable. If the signal is much weaker but still
above the noise -- say 1.30 microvolts -- then
S/N = 20 log10 (1.30) = 2.28 dB
This is a marginal situation. There might be some reduction in data speed under these
conditions.
If Vs is less than Vn, then S/N is negative. In this type of situation, reliable
communication is generally not possible unless steps are taken to increase the signal
level and/or decrease the noise level at the destination (receiving) computer or
terminal.

4.1.3 Profile Configuration
VDSL2 was developed and standardized in record time to address the shortcomings of
existing access technologies. It servers as the ideal xDSL technology for eliminating
last-mile bottlenecks and enable global mass deployment of advance Triple Play
services.
Unlike its predecessor, which allowed choosing either DMT (Discrete Multitone) or
QAM (Quadrature Amplitude Modulation) technology, VDSL2 only uses the DMT
line code.
DMT is a method of separating a DSL signal so that the usable frequency range is
separated into multiple small frequency bands, or tone. It uses up to 4096 tones which
are spaced 4 kHz or 8 kHz apart. Each tone can be used for either downstream or
upstream.
However VC-200M/VC-200S provide 10 VDSL2 profiles: 8a, 8b, 12a, 12b, and 17a

Appendix B Glossary
DHCP
DHCP stands for Dynamic Host Configuration Protocol. This protocol automatically
configures the TCP/IP settings of every computer on your home network.
DNS Server Address
DNS stands for Domain Name System, which allows Internet host computers to have a
192.34.45.8). A DNS server keeps a database of host computers and their respective
domain names and IP addresses, so that when a domain name is requested (as in typing
address. The DNS server address used by the computers on your home network is the
location of the DNS server your ISP has assigned.
DSL Modem
DSL stands for Digital Subscriber Line. A DSL modem uses your existing phone lines
to transmit data at high speeds.
Ethernet
A standard for computer networks. Ethernet networks are connected by special cables
and hubs, and move data around at up to 100 million bits per second (Mbps).
IP Address
IP stands for Internet Protocol. An IP address consists of a series of four numbers
separated by periods that identifies a single, unique Internet computer host. Example:
192.34.45.8.
ISP Gateway Address
(See ISP for definition). The ISP Gateway Address is an IP address for the Internet
router located at the ISP's office. This address is required only when using a cable or
DSL modem.
ISP

Internet Service Provider. An ISP is a business that provides connectivity to the Internet
for individuals and other businesses or organizations.
LAN
Local Area Network. A LAN is a group of computers and devices connected together in
a relatively small area (such as a house or an office). Your home network is considered
a LAN.
MAC Address
MAC stands for Media Access Control. A MAC address is the hardware address of a
device connected to a network.
NAT
Network Address Translation. This process allows all of the computers on your home
network to use one IP address. The NAT capability of the Device, allows you to access
the Internet from any computer on your home network without having to purchase more
IP addresses from your ISP.
Network Address Translation can be used to give multiple users access to the Internet
with a single user account, or to map the local address for an IP server(such as Web or
FTP) to a public address. This secures your network from direct attack by hackers, and
provides more flexible management by allowing you to change internal IP addresses
without affecting outside access to your network. NAT must be enabled to provide
multi-user access to the Internet or to use the Virtual Server function.
PPPoE
Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of secure
data transmission originally created for dial-up connections. PPPoE is for Ethernet
connections.
Subnet Mask
A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is
a set of four numbers configured like an IP address. It is used to create IP address
numbers used only within a particular network (as opposed to valid IP address numbers
recognized by the Internet.
