Avaya 1603SW Guia Do Utilizador

These steps offer a high-level description of the information exchanged when the telephone 
initializes and registers. This description assumes that all equipment is properly administered 
ahead of time. This description can help you understand how the 1603SW-I SIP Deskphones 
relate to the routers and servers in your network.

The deskphone is appropriately installed and powered. After a short initialization process, the 
deskphone identifies the LAN speed and sends a message out into the network, identifying 
itself and requesting further information. A router on the network receives and relays this 
message to the appropriate DHCP server.

An LLDP-enabled network provides information to the deskphone, as described in 

on page 91. Among other data passed to the telephone is the IP 

Address of the HTTP or HTTPS server.

The DHCP server provides information to the telephone, as described in 

on page 47. Among other data passed to the telephone is the IP Address of the HTTP 

or HTTPS server.

The 1603SW-I IP Deskphones can download upgrade files, binary files, language files, and 
settings files from either an HTTP or HTTPS server. The deskphone queries the file server, 
which transmits an upgrade file to the telephone. At a minimum, this 16xxupgrade.txt file tells 
the telephone which binary file the telephone must use. The binary file is the software that has 
the telephony functionality.

The telephone uses the 16xxupgrade.txt file to determine if it has the proper binary file. If the 
deskphone determines the proper binary file is missing, the deskphone requests an binary file 
download from the file server. The file server then downloads the file and conducts some 
checks to ensure that the file was downloaded properly. If the deskphone determines it already
