4.1.2 Line Configuration
Signal-to-Noise Ratio, often written S/N or SNR, is a measure of signal strength relative to background noise. The ratio is usually measured in decibels (dB).
If the incoming signal strength in microvolts is V s
, and the noise level, also in microvolts, is V n
, then the signal-to-noise ratio, S/N, in decibels is given by the formula
S/N = 20 log
10
(V s
/V n
)
If V s
= V n
, 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, V s
is greater than V n
, so S/N is positive. As an example, suppose that V s
=
10.0 microvolts and V n
= 1.00 microvolt. Then
S/N = 20 log
10
(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 log
10
(1.30) = 2.28 dB
This is a marginal situation. There might be some reduction in data speed under these conditions.
If V s
is less than V n
, 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
49
frequency bands.
Table 1 list 8a, 8b, 21a, 12b, and 17a standard VDSL2 profile about the bandwidth, tones, tone spacing, and line power.

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 domain name (such as www.planet.com.tw) and one or more IP addresses (such as
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
" www.planet.com.tw" into your Internet browser), the user is sent to the proper IP 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
54
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.
55
TCP/IP
Transmission Control Protocol/Internet Protocol. This is the standard protocol for data transmission over the Internet.
WAN
Specify the WAN connection type required by your Internet Service Provider, then click "Apply" to provide detailed configuration parameters for the selected connection type. Specify one of the first five options to configure a WAN connection through the
RJ-45 port.
