2 Installation Steps
2.1 Installation View
Please install your KE1020A as the connection chart above.
2.2 Connection Chart to Determine Cable Types

To determine the type of cable that you will need to connect to your terminal, look at the above
diagram and determine the number of your configuration. The lines marked 2, 4, 5,6,7,8 are
Straight-through Ethernet cable, the line marked 3 is Crossover Ethernet cable. If the ADSL/CABLE
Modem has the auto-reversal function (it usually has the function), the line marked 1 is
Straight-through Ethernet cable, and otherwise it is Crossover Ethernet cable.
Note: when the port LAN connects with line1,2,6,the equipments connected with port PC will not get
IP address(i.e., they can’t connect with Internet)
3 Ready to Use
First of all, you should obtain the IP address of the phone. Please press ESC key to view the IP address,
if the IP address is 0.0.0.0 or 255.255.255.255, you should contact the network administrator or
your service provider.
After getting the correct IP address, if your VoIP phone can not log into the server and go on
displaying Wait Logon, you may need to make network settings changes on the phone.
