5.3.5 Configuring Bridge Mode
RFC 1483 explains two methods for Multi-protocol Encapsulation over AAL5. The first method
allows multiplexing of multiple protocols over just one ATM virtual circuit (LLC-based
multiplexing). The second method assumes that each individual protocol is carried over a
29
separate ATM virtual circuit (VC-based multiplexing). Please refer to RFC 1483 for more
information.
The following table describes the labels in this screen.
LABEL

Your ISP should provide the above information. Click on BACK to return to the previous
screen, on NEXT to continue, or on EXIT to exit the wizard without saving.
5.3.6 Multiplexing
Two conventions identify what protocols a virtual circuit (VC) is carrying. Be sure to use the
multiplexing method your ISP requires.
(1) VC-Based Multiplexing
In VC-based multiplexing, by prior mutual agreement, each protocol is assigned to a
specific virtual circuit. For example, VC1 carries IP, etc. VC-based multiplexing may be
dominant in environments where dynamic creation of large numbers of ATM VCs is fast and
economical.
(2) LLC-Based Multiplexing
In LLC-based multiplexing, one VC carries multiple protocols with protocol-identifying
information contained in each packet header. While this method requires extra bandwidth and
processing overhead, this method may be advantageous if it is not practical to have a separate
VC for each carried protocol; for example, if charging heavily depends on the number of
30
simultaneous VCs.
5.3.7 VPI and VCI
Be sure to use the Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers
assigned to you. The valid range for the VPI is 0 to 255. The valid range for the VCI is 32 to
65535. 0 to 31 is reserved for local management of ATM traffic.
5.4 Finishing the Wizard
The Quick Start wizard now has all the information it needs. Click on BACK to make changes
or correct mistakes. Click on NEXT to save the current settings. Click on EXIT to exit the
wizard without saving.
Your changes have been saved. Click on CLOSE. The Quick Start wizard window will

6. Interface Setup
The physical connections determine whether the router ports are local area network
(LAN) ports or wide area network (WAN) ports. There are two kinds of IP networks. The local,
private kind is the LAN network; the global, public kind is the WAN network. The following
illustration shows the relationship between the router and the two different networks.
A LAN is a shared communication system to which many computers are attached. A LAN
is generally limited to the immediate area, usually the same building or floor of a building.
A WAN is an outside connection to another network or to the Internet.
Click an Interface Setup link to set ATM VC values, ISP Encapsulation, configure multiconnection settings, and LAN configuration.
6.1 Internet
The Internet screen allows you to set up how your router connects to the Internet. If you
already ran the Quick Start wizard, the information you provided to the wizard should be
entered into the fields already. After you finish the changes, click on the SAVE button to save
your changes.

6.1.1 ATM VC & QoS
ATM settings are used to connect to your ISP. Your ISP provides VPI, VCI, settings to you. In
this Device, you can totally setup 8 PVCs on different encapsulations if you apply 8 different
virtual circuits from your ISP. You need to activate the VC to take effect. For PVCs
management, you can use ATM QOS to setup each PVC traffic line’s priority.
Virtual Circuit: Select the VC number you want to setup.
VPI: Virtual Path Identifier. The valid range for the VPI is 0 to 255.
VCI: Virtual Channel Identifier. The valid range for the VCI is 1 to 65635 (0 to 31 is reserved for
local management of ATM traffic).
ATM QoS: Select the Quality of Service types for this Virtual Circuit. The ATM QoS types
include CBR(Constant Bit Rate), VBR(Variable Bit Rate) and UBR (Unspecified Bit Rate).
These QoS types are all controlled by the parameters specified below, including PCR, SCR,
and MBS.
PCR: Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This
parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes
(424 bits), so a maximum speed of 832 Kbps gives a maximum PCR of 1962 cells/sec. This
33
rate is not guaranteed because it is dependent on the line speed.
SCR: Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can
be sent at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than
the PCR; the system default is 0 cells/sec.
MBS: Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the
PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again.
At this time, more cells (up to the MBS) can be sent at the PCR again.
CBR is for connections that support constant rates of data transfer. The only parameter you
need to worry about in CBR is PCR.
UBR is for connections that have variable traffic. The only parameter you need to worry about
in UBR is PCR.
rtVBR is for connections that, while having variable traffic, require precise timing between
traffic source and destination. PCR, SCR and MBS must all be set for rtVBR.
nrtVBR is for connections that have variable traffic, do not require precise timing, but still
require a set bandwidth availability. PCR, SCR and MBS must all be set for nrtVBR.

Dynamic Route: Select the Dynamic Route from RIP1, RIP2-B, and RIP2-M. Please refer
to Internet
Dynamic Route. The only difference is the interface.
6.2.2 Explaining RIP Setup
Routing Information Protocol (RIP) allows a router to exchange routing information with
other routers. The RIP Direction field controls how RIP packets are allowed to enter and
leave the router. Selecting Both means the router will broadcast its routing table and
incorporate the RIP information that it receives. Selecting In Only means the router will
only accept RIP packets received, not send RIP packets. Selecting Out Only means
the router will only send RIP packets, not accept any RIP packets received.
Selecting None means the router will not send any RIP packets nor will it accept any RIP
packets received.
The Dynamic Route field controls the format and the broadcasting method of RIP
packets that the router sends. It recognizes both formats when receiving packets.
RIP-1 is universally supported, but RIP-2 carries more information. RIP-1 is adequate for
most networks. Only consider RIP-2 if your network has unusual topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format. RIP-2B uses subnet
broadcasting while RIP-2M uses multicasting.
Direction: Select the RIP direction from None, Both, In Only and Out Only.
Multicast: IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to
establish membership in a multicast group. The ADSL router supports both IGMP-v1 and
IGMP-v2. Select None to disable it. Please refer to Internet
Multicast. The only
difference is the interface.
6.2.3 DHCP Server
The DHCP Server gives out IP addresses when a device is booting up and request an IP
to be logged on to the network. It must be set as a DHCP client to obtain the IP address
automatically. By default, the DHCP Server is enabled. The DHCP address pool contains
the range of the IP address that will automatically be assigned to the client on the network.

6.2.4 DHCP Relay
A DHCP relay is a computer that forwards DHCP data between computers that request IP
addresses and the DHCP server that assigns the addresses. Each of the device’s
interfaces can be configured as a DHCP relay. If it is enable, the DHCP requests from local
PCs will forward to the DHCP server runs on WAN side. To have this function working
properly, please run on router mode only, disable the DHCP server on the LAN port, and
make sure the routing table has the correct routing entry.
DHCP Server IP for relay agent: The DHCP server IP Address runs on WAN side.
6.2.5 DNS Relay
The DNS Configuration allows the user to set the configuration of DNS.
40
DNS Rely Selection: If user wants to disable this feature, he just needs to set both
Primary & Secondary DNS to 0.0.0.0. Using DNS relay, users can setup DNS server IP to
192.168.1.1 on their computer. If not, device will perform as NO DNS relay.
If you don’t want to use the DNS Relay option, set the DNS relay to “Use User
Discovered DNS Server Only” and set both Primary and Secondary DNS Servers to
“0.0.0.0”.

without any data encryption. Select 64-bit WEP or 128-bit WEP to use data encryption.
Key#1~Key#4 The WEP keys are used to encrypt data. Both the ADSL Router and the
wireless clients must use the same WEP key for data transmission. If you chose 64-bit WEP,
then enter any 10 hexadecimal digits (“0-9”, “A-F”) preceded by 0x for each key (1-4). If you
choose 1280bit WEP, then enter 26 hexadecimal digits (“0-9”, “A-F”) preceded by 0x for each
key (1-4). The values must be set up exactly the same on the Access Points as they are on the
wireless client stations. The same value must be assigned to Key 1 on both access point (your
ADSL Router) and the client adapters, the same value must be assigned to Key 2 on both
access point and the client stations and so on, for all four WEP keys.
WPA-PSK Wi-Fi Protected Access, pre-shared key. Encrypts data frames before transmitting
over the wireless network.
Pre-shared Key is used to encrypt data. Both the ADSL Router and the wireless clients must
use the same WPA-PSK Key for data transmission.

7.2 Routing
This table lists IP address of Internet destinations commonly accessed by your network.
When a computer requests to send data to a listed destination, the device uses the Gateway
IP to identify the first Internet router it should contact to route the data most efficiently. Select
43
this option will list the routing table information. You can press ADD ROUTE to edit the static
route. (As below screen)
[Static Route]
Select this option to set Static Routing information.
Destination IP Address: This parameter specifies the IP network address of the final
destination of packets routed by this rule.
IP Subnet Mask: Enter the subnet mask for this destination.
Gateway IP Address: Enter the IP address of the gateway. A gateway does the actual
forwarding of the packets. Enter the gateway’s IP address in the field or select which PVC you
wish to act as a gateway.
The gateway is an immediate neighbor of your ADSL Router that will forward the packet to the
destination. On the LAN, the gateway must be a router on the same segment as your Router;
over Internet (WAN), the gateway must be the IP address of one of the remote nodes.
Metric: Metric represents the “cost” of transmission for routing purposes. IP Routing uses hop
count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter
a number that approximates the cost for this link. The number need not to be precise, but it
must between 1 and 15. In practice, 2 or 3 is usually a good number.
44
Announced in RIP: This parameter determines if the ADSL router includes the router to this
remote node in its RIP broadcasts. If you choose Yes, the router in this remote node will be
propagated to other hosts through RIP broadcasts. If you choose No, this route is kept private
and is not included in the RIP broadcasts.

7.3 NAT
Network Address Translation (NAT) is a method for disguising the private IP addresses
you use on your LAN as the public IP address you use on the Internet. You define NAT rules
that specify exactly how and when to translate between public and private IP addresses.
Simply select this option to setup the NAT function for your ADSL router.
Virtual Circuit (VC): The Virtual Circuit (VC) properties of the ATM VC interface identify a
unique path that your ADSL/Ethernet router uses to communicate via the ATM-based network
with the telephone company central office equipment.
NAT Status: This filed shows the current status of the NAT function for the current VC.
Number of IPs: This field is to specify how many IPs are provided by your ISP for current VC.
It can be single IP or multiple IPs.
45
Note: For VCs with single IP, they share the same DMZ & Virtual servers; for VCs with multiple
IPs, each VC cab set DMZ and Virtual servers. Furthermore, for VCs with multiple IPs, they
can define the Address Mapping rules; for VCs with single IP, since they have only one IP,
there is no need to individually define the Address Mapping rule.
7.3.1 What NAT Does
NAT changes the source IP address in a packet received from a subscriber (the inside local
address) to another (the inside global address) before forwarding the packet to the WAN side.
When the response comes back, NAT translates the destination address (the inside global
address) back to the inside local address before forwarding it to the original inside host. Note
that the IP address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by
the ISP. You may also designate servers, such as a Web server and a telnet server, on your
local network and make them accessible to the outside world. With no servers defined, your
ROUTER filters out all incoming inquiries, thus preventing intruders from probing your network.
For more information on IP address translation, refer to RFC 1631, The IP Network Address
Translator (NAT).
Inside/outside indicates where a host is located relative to the ROUTER. The computers hosts
of your LAN are inside, while the Web servers on the Internet are outside.
Global/local indicates the IP address of a host in a packet as the packet traverses a router.
The local address refers to the IP address of a host when the packet is in the local network,
while the global address refers to the IP address of the host when the same packet is traveling
in the WAN side.
Note that inside/outside refers to the location of a host, while global/local refers to the IP
address of a host used in a packet. Thus, an inside local address (ILA) is the IP address of an
inside host of a packet when the packet is still in the local network, while an inside global
address (IGA) is the IP address of the same inside host when the packet is on the WAN side.
The following table summarizes this information.
ITEM
DESCRIPTION
Inside
This refers to the host on the LAN.
Outside
This refers to the host on the WAN.
Local
This refers to the packet address (source or destination) as the packet
travels on the LAN.
Global
This refers to the packet address (source or destination) as the packet
travels on the WAN.
46
7.3.2 How NAT Works
Each packet has two addresses – a source address and a destination address. For outgoing
packets, the ILA is the source address on the LAN, and the IGA is the source address on the
WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the
destination address on the WAN. NAT maps private (local) IP addresses to globally unique
ones required for communication with hosts on other networks. It replaces the original IP
source address (and TCP or UDP source port numbers for Many-to-One and Many-to-Many
Overload NAT mapping) in each packet and then forwards it to the Internet. The ROUTER
keeps track of the original addresses and port numbers so incoming reply packets can have
their original values restored.
The following figure illustrates this.
47
7.3.3 NAT Application
The following figure illustrates a possible NAT application, where three inside LANs (logical
LANs using IP Alias) behind the router can communicate with three distinct WAN networks.
More examples follow at the end of this chapter.
7.3.4 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
a. One-to-One: In One-to-One mode, the TC3162 EVM maps one local IP address to one
global IP address.
b. Many-to-One: In Many-to-One mode, the TC3162 EVM maps multiple local IP addresses to
one global IP address.
c. Many-to-Many Overload: In Many-to-Many Overload mode, the TC3162 EVM maps
multiple local IP addresses to shared global IP addresses.
d. Many-to-Many No Overload: In Many-to-Many No Overload mode, the TC3162 EVM maps
each local IP address to a unique global IP address.
e. Server: This type allows you to specify inside servers of different services behind the NAT
to be accessible to the outside world.
The following table summarizes these types.

8. Access Management
8.1 ACL
Go to Access Management
ACL to enable remote management. Access Control Listing
(ACL) is a management tool that acts as a filter for incoming or outgoing packets, based on
application. You may use telnet or Web to remotely manage the ADSL Router. User just needs
to enable Telnet or Web and give it an IP address that wants to access the ADSL Router. The
default IP 0.0.0.0 allows any client to use this service to remotely manage the ADSL Router.
ACL: There has Activated & Deactivated option. The default setting is Deactivated which
means all IP can access via router. If you choose Activated, you only can access via router by
listed IP addresses.
ACL Rule Index: Index number from 1 and up to 16.
Active: Once you choose Yes then you can access the IP via router.
Application: Each of these labels denotes a service that you may use to remotely manage the
Router. Choices are Web, FTP, Telnet, SNMP, Ping, ALL.
Interface: Select the access interface. Choices are WAN, LAN and Both.
53
For Example:
How to set your ACL?
1. You must choose Activated to enable your ACL function.
2. Select the ACL Rule Index number (up to 16 number)
3. You can set the specific Secure IP address or set 0.0.0.0 for all IPs.
4. Choose the Application which you want to access for this ACL Rule index.
5. Select the Interface you want to access from.
6. After all settings are ready, click SAVE and continue next ACL Rule Index setting.
[Note]
1. You must set one ACL index to access your router via LAN interface. If you don’t, your
router cannot access other listed IP Address. (Refer to Index 1).
2. Remember! Once you active your ACL function, you only can access via router by
listed Secure IP Address.
54
8.2 IP Filter
The Router provides extensive firewall protection by restricting connection parameters to limit
the risk of intrusion and defending against a wide array of common hacker attackers. Go to
Access Management
IP Filtering to set different IP filter rules of a given protocol (TCP,
UDP, or ICMP) and a specific direction (incoming, outgoing, or both) to filter the packets.
IP Filter is a more complex filtering tool, based more on IP and custom rules. Each of the
indices can hold six rules, and each interface can have four associated indices, allowing 24
rules per interface. If all six rules in an index are Next rules, the data will be sent to the next
index for filtering.
IP Filter Set Index: The IP Filter Set Index from 1 to 12 and each index can set up to 6 IP
Filter.
Interface: Choices from PVC0 to PVC7 and LAN.
Direction: Choices are Both, Incoming and Outgoing. Select which direction of data flow
you wish to apply the filters to. Note that Incoming and Outgoing are from the point of view of
55
your router, relative to the interface you select. For WAN, data coming from outside your
system is considered Incoming and data leaving your system is Outgoing. For LAN, data
leaving your system is considered Incoming and data entering your system is Outgoing.
IP Filter Rule Editing: Select the IP Filter Rule Index you wish to modify.
Active: Toggle this rule index on or off with Yes or No, respectively.
Source IP Address: Enter the source IP address you wish to deny access to your system.
Subnet Mask: Enter the subnet mask of the source IP address.
Port Number: Enter the port number of the source IP address. Note that 0 means all that ports
are allowed.
Destination IP Address: Enter the destination IP address that you wish to deny access to
your system.
Subnet Mask: Enter the subnet mask of the destination IP address
Port Number: Enter the port number of the destination IP address. Note that 0 means that all
ports are allowed
Protocol: Select the protocol to filter. Choices are TCP, UDP, and ICMP.
Rule Unmatched: Choices are Forward and Next. Select what happens to the data in
question if the rule you are currently editing is unmatched. Next means that the data is then
compared to the next IP filter rule. Forward means that the data will be allowed into your
system. Note that a Forward rule should be the last rule, as no data will be compared to rules
after a Forward rule.
IP Filter Set Index: Select the IP filter set you wish to view.
56
For Example
Please follow below steps to set your IP Filter:
1. IP Filter Set Editing: Choose your IP Filter Set Index, Interface and Direction options.
Remember, Interface and Direction functions are affected with IP Filter Set Index. EX: if
st
your 1 index set of IP filter set PVC0 as Interface and Outgoing as Direction, so the list of
st
1 IP Filter will be PVC0 and Outgoing as their settings.
2. IP Filter Rule Editing: Select the IP Filter Rule Index (up to 6 numbers for each set index)
and choose Active option.
As below example, Source IP Address is 192.168.1.4,
Subnet Mask is 255.255.255.255, Destination IP Address & Subnet Mask is 0.0.0.0,

8.3 SNMP
The Simple Network Management Protocol (SNMP) is used for exchanging information
between network devices. It enables a host computer to access configuration, performance,
and other system data that resides in a database on the modem. The host computer is called a
management station and the modem is called an SNMP agent. The data that can be accessed
via SNMP is stored in a Management Information Database (MIB) on the modem.
Get Community: Select to set the password for incoming Get- and GetNext request from
management station.
Set Community: Select to set the password for incoming Set request from management
station.
The default password is ‘public’. When you are done making changes, click on SAVE to save
your changes.
8.4 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.
58
UPnP (Universal Plug and Play): You can choose “Activated” or “Deactivated” option from
this session.
Auto-Configured (by UPnP Application): UPnP network devices can automatically
configure network addressing, announce their presence in the network to other UPnP devices
and enable exchange of simple product and service descriptions. Choose “Activated” option
to allow UPnP-enabled applications to automatically configure the ADSL Router so that they
can communicate through the ADSL Router, for example by using NAT traversal, UPnP
applications automatically reserve a NAT forwarding port in order to communicate with another
UPnP enabled device; this eliminates the need to manually configure port forwarding for the
UPP enabled application.
If you don’t want to make configuration changes through UPnP,
just choose “Deactivated”.
SAVE: Click SAVE to save the setting to the ADSL Router.
8.5 DDNS
The Dynamic Domain Name System allows you to update your current dynamic IP
address with one or many dynamic DNS services so that anyone can contact you (in
NetMeeting, CU-SeeMe, etc.). You can also access your FTP server or Web site on your own
computer using a DNS-like address (for instance myhost.dhs.org, where my host is a name of
your choice) that will never change instead of using an IP address that changes each time you
reconnect. Your friends or relatives will always be able to call you even if they don't know your
IP address. First of all, you need to have registered a dynamic DNS account with
59
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that
would still like to have a DNS name. The Dynamic DNS service provider will give you a
password or key.
Dynamic DNS: Choose the option for Activated or Deactivated DDNS.
Service Provider: The default Dynamic DNS service provider is www.dyndns.org.
My Host Name: Type the domain name assigned to your ADSL by your Dynamic DNS
provider.
E-mail Address: Type your e-mail address.
Username: Type your user name.
Password: Type the password assigned to you.
Wildcard support: Select Yes or No to turn on DYNDNS Wildcard.
DYNDNS
Wildcard
-->
Enabling
the
wildcard
feature
for
your
host
causes
*.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This
feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still
reach your hostname.
SAVE: Click SAVE to save your changes.
Note that you must enter the user name exactly as your ISP assigned it. If the assigned name
is in the form of user@domain where domain identifies a service name, enter it exactly as
given. When you are done making changes, click on SAVE to save your changes.

Make sure your computer’s Ethernet card is working properly.
If these steps fail to correct the problem, contact your local distributor for assistance.
11.1.3 ADSL LED
The ADSL LED on the front panel does not light up.
STEPS
CORRECTIVE ACTION
Check the telephone wire and connections between the router ADSL port and the wall
jack.
Make sure that the telephone company has checked your phone line and set it up for
ADSL service.
Reset your ADSL line to reinitialize your link to the DSLAM.
If these steps fail to correct the problem, contact your local distributor for assistance.
71
11.2 Problems with the Web Interface
I cannot access the web Interface.
STEPS
CORRECTIVE ACTION
Make sure you are using the correct IP address of the router. Check the IP address of
the router.
Make sure that there is not a console session running.
Check that you have enabled web service access. If you have configured a secured
client IP address, your computer’s IP address must match it. Refer to the chapter on
remote management for details.
For WAN access, you must configure remote management to allow server access from
the WAN (or all).
Your computer’s and the router’s IP addresses must be on the same subnet for LAN
access.
If you changed the router’s LAN IP address, then enter the new one as the URL.
Remove any filters in LAN or WAN that block web service.
The web Interface does not display properly.
STEPS
CORRECTIVE ACTION
Make sure you are using Internet Explorer 5.0 and later versions.
Delete the temporary web files and log in again.
In Internet Explorer, click Tools, Internet Options and then click the Delete Files ...
button.
When a Delete Files window displays, select Delete all offline content and click OK.
(Steps may vary depending on the version of your Internet browser.)
11.3 Problems with the Login Username and Password

the default configuration file. This will erase all custom configurations and restore all of
the factory defaults including the password.
Press the DEFAULT button for five seconds, and then release it. When the ADSL LED
begins to blink, the defaults have been restored and the router restarts.
The default username is “admin”. The default password is “trendchip”. The Password
and Username fields are case-sensitive. Make sure that you enter the correct password
and username using the proper casing.
It is highly recommended to change the default username and password. Make sure
you store the username and password in a save place.
72
11.4 Problems with LAN Interface
I cannot access the router from the LAN or ping any computer on the LAN.
STEPS
CORRECTIVE ACTION
Check the Ethernet LEDs on the front panel. A LAN LED should be on for a port that has
a PC connected. If it is off, check the cables between your router and the PC. Make sure
you have uninstalled any software firewall for troubleshooting.
Make sure that the IP address and the subnet mask is consistent between the router
and the workstation.
11.5 Problems with WAN Interface
Initialization of the ADSL connection failed.
STEPS
CORRECTIVE ACTION
Check the cable connections between the ADSL port and the wall jack. The ADSL LED
on the front panel of the router should be on.
Check that your VPI, VCI, type of encapsulation and type of multiplexing settings are the
same as what you collected from your telephone company and ISP.
Restart the router. If you still have problems, you may need to verify your VPI, VCI, type
of encapsulation and type of multiplexing settings with the telephone company and ISP.
I cannot get a WAN IP address from the ISP.
STEPS
CORRECTIVE ACTION
Ensure that all other devices connected to the same telephone line as your router (e.g.
telephones, fax machines, analogue modems) have a line filter connected between
them and the wall socket (unless your are using a Central Splitter or Central Filter
installed by the qualified and licensed electrician), and ensure that all line filters are
correctly installed and right way around.
Missing line filters or line filters installed the wrong way around can cause problems with
your ADSL connection, including causing frequent disconnects.
Frequent loss of ADSL line sync (disconnections).
STEPS
CORRECTIVE ACTION
The ISP provides the WAN IP address after authenticating you. Authentication may be
through the user name and password, the MAC address or the host name.
The username and password apply to PPPoE and PPoA encapsulation only. Make sure
that you have entered the correct Service Type, User Name and Password (be sure to
use the correct casing).
73
11.6 Problems with the Internet Access
