A malfunction is any error of internal sequence or state
that will prevent the device from connecting to the
DSLAM or passing customer data. This may be
identified at various times such after power on or
during operation through the use of self testing or in
operations which result in a unit state that is not
expected or should not occur.
Green On An Ethernet Link is established.
Off An Ethernet Link is not established.
Green Blink Data transmitting or receiving over LAN.
Green On The wireless module is ready and idle.
Off The wireless module is not installed.
Green Blink Data transmitting or receiving over WLAN.
Green On A USB link is established.
Off A USB link is not established.
Green Blink Data transmitting or receiving over USB.

ADSL
Green On DSL good sync
Off Modem power off
Green Blink Flashing Green = DSL attempting sync
Flashing at 2 Hz with a 50% duty cycle when trying to
detect carrier signal
Flashing at 4 Hz with a 50% duty cycle when the carrier
has been detected and the modem is trying to train.
Green On IP connected and no traffic detected. If an IP or PPPoE
session is dropped due to an idle timeout, the light will
remain green if an ADSL connection is still present.
Off Modem power off, modem in bridged mode or ADSL
connection not present. Also, if an IP or PPPoE session
is dropped for any reason, other than an idle timeout,
INTERNET
the light is turned off.
Green Blink IP connected and IP Traffic is passing thru the device
(either direction)
Red On Device attempted to become IP connected and failed
(no DHCP response, no PPPoE response, PPPoE
authentication failed, no IP address from IPCP, etc.)
The light will turn red when it attempts to reconnect
and DHCP or PPPoE fails.

Chapter 2 Installation
2.1 Hardware Installation
In the rear panel, there is a reset button. To load the factory default settings, hold
the reset button down for at least 5 seconds.
Follow the instructions below to complete the hardware connections.
Connection to LINE port
If you wish to connect both the router and a telephone, connect the LINE port to a
POTS splitter with a RJ11 connection cable.
Connection to LAN port
To connect to a hub or PC, use a RJ45 cable. You can connect the router to up to four
LAN devices. The ports are auto-sensing MDI/X and either straight-through cable
or crossover cable can be used.
Connection to USB port
Connect the USB port to a PC with a standard USB cable.
9
Connection to Power
Connect the Power jack to the shipped power cord. Attach the power adapter to
the wall outlet or other AC source.
After all connections have been made, press the power-switch in to turn the device
on. After power on, the router performs a self-test. Wait for a few seconds until the
test is finished, then the router will be ready to operate.
Caution 1: If the router fails to power up, or it malfunctions, first verify that the
power supply is connected correctly. Then power it on again. If the
problem persists, contact our technical support engineers.
Caution 2: Before servicing or disassembling this equipment always disconnect all
power cords and telephone lines from the wall outlet.

Chapter 3 Login via the Web Browser
This section describes how to manage the router via a Web browser via the remote
end. You can use a web browser such as Microsoft Internet Explorer, or Netscape
Navigator. (The Web page is best viewed with Microsoft Internet Explorer 5.0 and
later): A unique default user account is assigned with user name root and password
12345. The user can change the default password later when logged in to the
device.
3.1 IP Address
The default IP address of the CT-5361T (LAN port) is 192.168.1.1. To configure the
CT-5361T for the first time, the configuration PC must have a static IP address
within the 192.168.1.x subnet. Follow the steps below to configure your PC IP
address to use subnet 192.168.1.x.
STEP 1: Right click on the Local Area Connection under the Network and Dial-Up
connection window and select Properties.
STEP 2: Enter the TCP/IP screen and change the IP address to the domain of
192.168.1.x/24.
19
STEP 3: Click OK to submit the settings.
STEP 4: Start your Internet browser and type the IP address for the router
(192.168.1.1) in the Web address bar.

3.2 Login Procedure
Perform the following steps to bring up the Web user interface and configure the
CT-5361T. To log on to the system from the Web browser, follow the steps below:
STEP 1: Start your Internet browser. Type the IP address for the router in the Web
address field. For example, if the IP address is 192.168.1.1, type
http://192.168.1.1
STEP 2: You will be prompted to enter your user name and password. Type root in
the user name and 12345 in the password field, and click OK. These
values can be changed later in the Web User Interface by selecting the
Management link.

3.3 Default Settings
During power on initialization, the CT-5361T initializes all configuration attributes to
default values. It will then read the configuration profile from the Permanent
Storage section on the flash memory. The default attributes are overridden when
identical attributes with different values are configured. The configuration profile
in Permanent Storage can be created via the Web user interface, telnet user
interface, or other management protocols. The factory default configuration can be
restored either by pushing the reset button for more than five seconds, or by
clicking the Restore Default Configuration option in the Restore Settings screen.
The following default settings are present when setting up the router for the first
time. The PC running the browser can be attached to the Ethernet.
