Dynamic Addressing Process - Avaya 4600 Series Installation Manual

Dynamic Addressing Process

Before beginning this process, you must have an extension number for the IP Telephone
and the DEFINITY/MultiVantage security code (password) for that extension.
The following description of the process of installing the IP telephones assumes that the process is
executed successfully. Only an initial installation (out of the box) is described. For errors that may
be encountered during the process and the messages displayed, see Chapter 4: Troubleshooting
Guidelines.
When you plug the IP Telephone set into the Ethernet wall jack, the following process takes place.
If the application has already been downloaded, the whole process takes approximately 1
to 2 minutes after the phone is plugged in. For an initial installation (including download of
the application) the process may take 5 - 10 minutes. The duration is based on LAN
loading, how many phones are being installed at once, and similar factors.
1. The telephone activates the Ethernet line interface, the secondary Ethernet jack, and dial pad
input (to allow the invocation of procedures) as soon as possible after power-up or a reset.
The telephone detects and displays the speed of the Ethernet interface in Mbps (that is, 10 or
100). The message No Ethernet is displayed until the software determines whether the
interface is 10 Mbps or 100 Mbps.
The Ethernet speed indicated is the LAN interface speed for both the telephone and
any attached PC.
2. The IP telephone sends a request to the DHCP server and invokes the DHCP process.
The following message is displayed:
DHCP: s secs,
* to program
where s is the number of seconds that have elapsed since DHCP was invoked.
3. The DHCP server provides IP addresses for the following:
The IP Telephone
The TFTP server
The TN799 Control-LAN (CLAN) circuit pack on the call server
4. The IP Telephone connects to the TFTP server and looks for an upgrade script file.
5. The TFTP server sends an upgrade script, telling the phone what it is.
