ADSL (Asymmetric Digital Subscriber Line)
2.1. What is ADSL?
ADSL is an asymmetrical technology, meaning that the downstream data rate is
much higher than the upstream data rate. It enhances the data capacity of the
existing twisted-pair wire that runs between the local telephone company switching
offices and most homes and offices. ADSL is suitable for Internet users because
more information is usually downloaded than uploaded. For example, a simple
button click in a web browser can start an extended download that includes
graphics and text. ADSL operates in a frequency range that is above the frequency
range of voice services, so the two systems can operate over the same cable.
The advantages of ADSL form the point of view of the Network Service Provider
and the end users:
1. ADSL enables Telcos to use the existing copper wires around the world to
deliver affordable high-speed remote access to the Internet, corporate
networks and on-line services over ordinary phone lines.
2. There is no time wasted for dialing up, ADSL is “always on” and connected,
waiting ready for use.
3. ADSL provides service providers with the capability to use one line to provide
new data services while maintaining the telephone service on the same line,
thus no need to increase any new infrastructures.
4. This new technology empowers the communicating speed nearly 300 times
faster than 24.4 Kbps modems or over 100 times faster than 56Kbps
modems.
5. ADSL enables real-time interactive multimedia applications, such as video

13
conferencing, distance learning and video-on-demand.
6. ADSL provides Telcos with the ability to offer a private, secure channel of
communications between the consumer and the service provider.
7. Data stream travels along the customers’ own line. It is quite unlike traditional
telephone and modem services sharing the line with others.
8. Using a customer’s dedicated line, ADSL transmission speeds are not
affected by other users going on line.
9. You can use telephone for normal conversations and high-speed conduit for
data, information, entertainment and more at the same time. It provides
enormous advantages both in office and at home.
2.2. VPI & VCI
The valid range for the VPI is 1 to 255. The VCI is 32 to 65535 since 1 to 31 is
reserved for local management of ATM traffic. Your Telecos should supply you with
these numbers.
ATM is a connection-oriented technology.It sets up virtual circuits over which end
systems communicate. The terminology for virtual circuits involves VC (virtual
channel) and VP (virtual path). VC is the logical connections between end stations
and VP is a bundle of VCs.
We can think of a VP as a cable that contains a bundle of wires. The cable
connects two points, and wires within the cable provide individual circuits between
the two points. In an ATM cell header, a VPI identifies a link formed by a virtual
path and a VCI identifies a channel within a virtual path. The VPI and VCI are
identified and correspond to termination points at ATM switched as shown below.

14
VPI’s & VCI’s
2.3. Multiplexing
There are two conventions to identify what protocols the virtual circuit (VC) is
carrying. Be sure to use the multiplexing method required by your ISP.
??VC-based multiplexing
Each protocol is assigned to a specific virtual circuit, e.g., VC1carries IP, VC2
carries IPX, etc. VC-based multiplexing may be dominant in environments
where dynamic creation of large numbers of ATM VCs in fast and economical.
??LLC-based multiplexing
VC carries multiple protocols with protocol identifying information being
contained in each packet header. Despite the extra bandwidth and processing
overhead, this method may be advantageous if it is not practical to have a
separate VC for each carried protocol, e.g., if charging heavily depends on the
number of simultaneous VCs.
2.4. PPPoE
When using SP3353 as a PPPoE client, the PCs on the LAN see only Ethernet and
are not aware of PPPoE. This alleviates the administrator from having to manage
the PPPoE clients on the individual PCs.

15
What is PPPoE?
PPPoE (Point-to-Point Protocol over Ethernet) emulates a Dial-Up connection. It
allows your ISP to use their existing network configuration with newer broadband
technologies such as ADSL. The PPPoE driver on Micronet SP3353 istransparent
to the PCs on the LAN, which see onlyEthernet and are not aware of PPPoE thus
saving you from having to manage PPPoE clients on individual PCs.
An ADSL modem bridges a PPP session over Ethernet from your PC to an ATM
PVC (Permanent Virtual Circuit),which connects to a xDSL Access Concentrator
where the PPP session terminates (see the figure below). One PVC can support
any number of PPP sessions from your LAN. PPPoE provides access control and
billing functionality in a manner similar to dial-up services using PPP.
Like the architecture shown above, the PPPoE driver makes the Ethernet appear
as a serial link to the PC, while the modem bridges the Ethernet frames to the
Access Concentrator (AC). Between the AC and an ISP, the AC is acting as a L2TP
(Layer 2 Tunneling Protocol) LAC (L2TP Access Concentrator) and tunnels the
PPP frames to the ISP. The L2TP tunnel is capable of carrying multiple PPP
sessions. With PPPoE, the VC (Virtual Circuit) is equivalent to the dial-up
connection and is between the modem and the AC, as opposed to all the way to
the ISP. However, the PPP negotiation is between the PC and the ISP.

16
Benefits of PPPoE
PPPoE offers the following benefits:
1. It provides a familiar dial-up networking (DUN) user interface.
2. PPPoE lessens the burden on the carriers of provisioning virtual circuits all the
way to the ISP on multiple switches for thousands of users. For PSTN and
ISDN, the switching fabric is already in place.
3. It allows the ISP to use the existing dial-up model to authenticate and to
provide differentiated services.

Introduction To Internet ADSL Router
Micronet’s BroadlinkTM SP3353 is an ADSL Router embeddedADSL modem and
built-in 4-port auto-uplink Ethernet switch. Please prepare a PC with an Ethernet
port before configure the ADSL Router.
3.1. The Front Panel
The front panel of the ADSL Router is shown below.
System LEDs
Power Lights green when the ADSL Router is receiving power.
Status The LED will be dark for 10 seconds when the system is started.
After that, the LED will blink periodically to show the ADSL Router is
working normally. If the LED stays green/dark that means the system
is fail, you need to try to reboot the system or contact your agent.
Port LEDs (ADSL)
LINK The LED stays light (green) means the port has good linkage to its
associated devices.
ACT The activity LED will blink green when there is traffic transfer to the
port.

18
Port LEDs (LAN)
FDX/COL A collision occurs when two stations within a collision
domain attempt
to transmit data at the same time. Intermittent flashing amber of the
collision LED is normal; the contending adapters resolve each
collision by means of a wait-then-retransmit algorithm. Frequency of
collision is an indicator of heavy traffic on the network. If the
FDX/COL lights amber it means the port is under full-duplex
operation or dark for half-duplex mode.
LINK/ACT Every port has a LINK/ACT LED. Steady green (link state) indicates
that the port has good linkage to its associated device. Flashing
green indicates that the port is receiving or transmitting data between
its associated devices.
SPEED The SPEED LED indicates the link speed of each port. If the LED
lights green then the connection speed is 100Mbps, off for 10Mbps.
Factory
Setting
Button
Push the button for 5 seconds, the system will return to factory
default setting. In the meantime, system rewrite flash to default value
and Status LED halts for a while. Approximately 60 seconds later, the
Status LED blinks green periodically, now the whole system
parameters have returned to factory default value. If the process has
been interrupted by any reason (power off……), the system will fail.
Befor performing the process, ensure a safe operating environment
please!
