IP Telephony Configuration Guide
Using a 3-port switch
In an office environment where a LAN network already exists, most computers will already be
connected to a LAN line. To avoid the necessity of installing duplicate network connections, you
can use a Nortel Networks 3-port switch for each i2002 and i2004 telephone. This switch allows
the telephone and computer to connect to the same network connection. For more information,
consult the i2002/i2004 and the 3-way switch documentation.
Connecting the i2002 or i2004 telephone
Follow these steps to connect an i2002 or i2004 telephone:
1 Connect one end of the handset cord to the handset jack on the telephone base. Connect the
other end of the handset cord to the handset.
2 Connect one end of a Cat-5 line cord with RJ45 connectors to the line cord jack on the
telephone base. Connect the other end of the line cord to the Ethernet connection or to the
3-way switch connector.
3 Plug the AC Power adapter into the base of the telephone, and then plug the adapter into the
AC outlet.
Configuring the i2002 or i2004 telephone to the system
Configuring IP telephones involves two processes:
• If DHCP service on the BCM is active or the Customer DHCP server has been configured to
hand out the specific BCM details, the IP telephone will automatically attempt to find the
server. Once you register the telephone to the system, as described in “Registering the
telephone to the system”, the telephone assumes the parameters it receives from the system,
which are described in “Configuring telephone settings”.
• If DHCP is not configured to provide system information, or if you are not using DHCP on
your network, you need to configure your telephone parameters before the telephone can
register to the system. In this case, follow the directions in “Configuring telephone settings”,
and then follow any of the prompts that appear, as described in “Registering the telephone to
the system”.
Registering the telephone to the system
When you first connect the telephone to the IP connection, you may receive one of the following:
• If the telephone is not yet registered, and if a password was entered in the Terminal
Registration screen, the telephone prompts you for that password.
• If you set Auto Assign DN on the Business Communications Manager to OFF, the telephone
prompts you for a DN.
• If you are prompted for a password, enter the password and press OK.
• If you are prompted for a DN, enter the DN you want assigned to this telephone and press OK.
