Chapter 2 Installation
2.1 Hardware Installation
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. The port is 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.
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, turn the power-switch to the on position. After
powering 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.
Reset Button
Restore the default parameters of the router by holding down the device’s Reset button
until the LED’s start blinking simultaneously (about 5 seconds). After the device has
rebooted successfully, and if the connection is established, the LAN LED, ADSL LED or
USB LED will display in green, depending on the connection type.
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 admin and
password tot. 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-5611T (LAN port) is 192.168.1.1. To configure the
CT-5611T 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.
STEP 3: Click OK to submit the settings.
STEP 4: Start your Internet browser with the default IP address 192.168.1.1.
21
3.2 Login Procedure
Perform the following steps to bring up the Web user interface and configure the CT5611T. 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 admin
in the user name field and tot in the password field, and click OK. These
values can be changed later in the Web User Interface by selecting the

3.3 Default Settings
During power on initialization, the CT-5611T 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, the console, or 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 or the USB.
