Quick Setup
The Quick Setup allows the user to configure the ADSL router for DSL connectivity
and Internet access. It also guides the user though the WAN network setup first and
then the LAN interface setup. You can either manually customize the router or follow
the online instruction to set up the router.
The CT-5071 ADSL router supports the following five network operating modes over
an ATM PVC WAN interface.
PPP over Ethernet (PPPoE)
PPP over ATM (PPPoA)
MAC Encapsulated Routing (MER)
IP over ATM (IPoA)
Bridging
The following configuration considerations apply:
The WAN network operating mode operation depends on the service provider’s
configuration on the Central Office side and Broadband Access Server for the
PVC
If the service provider provides PPPoE service, then the connection selection
depends on whether the LAN-side device (typically a PC) is running a PPPoE
client or whether the CT-5071 is to run the PPPoE client. The CT-5071 can
support both cases simultaneously.
If some or none of the LAN-side devices do not run PPPoE client, then select
PPPoE. If every LAN-side device is running a PPPoE client, then select Bridge In
PPPoE mode, CT-5071 also supports pass-through PPPoE sessions from the LAN
side while simultaneously running a PPPoE client fro non-PPPoE LAN devices.
NAPT and firewall are always enabled when PPPoE mode is selected, but they
can be enabled or disabled by the user when MER or IPoA is selected, NAPT and
firewall are always disabled when Bridge mode is selected.
Depending on the network operating mode, and whether NAPT and firewall are
enabled or disabled, the main panel will display or hide the NAPT/Firewall menu.
For instance, at initial setup, the default network operating mode is Bridge. The
main panel will not show the NAPT and Firewall menu.
Note: Up to eight PVC profiles can be configured and saved on the flash memory.
To activate a particular PVC profile, you need to navigate all the Quick Setup
pages until the last summary page, then click on the Finish button and reboot the
system.

4.1
Auto Quick Setup
The auto quick setup requires the ADSL link to be up. The ADSL router will
automatically detect the PVC. You only need to follow the online instructions that
you are prompted.
1. Select Quick Setup to display the DSL Quick Setup screen.
2. Click Next to start the setup process. Follow the online instructions to complete
the setting. This procedure will skip some processes like PVC index, or
encapsulation.
3. After the settings are complete, you can use the ADSL service.
4.2
Manual Quick Setup
STEP 1: Click Quick Setup and un-tick the DSL Auto-connect checkbox to enable
manual configuration of the connection type.
Un-tick this checkbox to enable manual setup and display
the following screen.

STEP 3: Then, choose the Encapsulation mode.
STEP 4: Click Next to display the following screen. Choosing different connection
types pops up different settings requests. Enter appropriate settings that are
requested by your service provider. The following descriptions state each
connection type setup separately.
13
PPP over ATM (PPPoA) and PPP over Ethernet (PPPoE)
1. Select the PPP over ATM (PPPoA) or PPP over Ethernet (PPPoE) radio
button and click Next. The following screen appears:
PPP USERNAME/PPP PASSWORD
The PPP Username and the PPP password requirement are dependent on the
particular requirements of the ISP or the ADSL service provider. The WEB user
interface allows a maximum of 256 characters in the PPP user name and a maximum
of 32 characters in PPP password.
Encapsulation Mode
Choosing different connection types provides different encapsulation modes.
PPPoA- VC/MUX, LLC/ENCAPSULATION
PPPoE- LLC/SNAP BRIDGING, VC/MUX
MER- LLC/SNAP-BRIDGING, VC/MUX
IPoA- LLC/SNAP-ROUTING, VC MUX
Bridging- LLC/SNAP-BRIDGING, VC/MUX
14
Disconnect if no activity
The CT-5071 can be configured to disconnect if there is no activity for a period of
time by selecting the Disconnect if no activity check box. When the checkbox is
ticked, you need to enter the inactivity timeout period. The timeout period ranges
from 1 minute to 4320 minutes.
PPP IP Extension
The PPP IP Extension is a special feature deployed by some service providers. Unless
your service provider specially requires this setup, do not select it.
The PPP IP Extension supports the following conditions:
Allows only one PC on the LAN
The public IP address assigned by the remote side using the PPP/IPCP protocol
is actually not used on the WAN PPP interface. Instead, it is forwarded to the
PC’s LAN interface through DHCP. Only one PC on the LAN can be connected to
the remote, since the DHCP server within the ADSL router has a single IP
address to assign to a LAN device.
NAPT and firewall are disabled when this option is selected.
The ADSL router becomes the default gateway and DNS server to the PC
through DHCP using the LAN interface IP address.
The ADSL router extends the IP subnet at the remote service provider to the
LAN PC. That is, the PC becomes a host belonging to the same IP subnet.
The ADSL router bridges the IP packets between WAN and LAN ports, unless the
packet is addressed to the router’s LAN IP address.
