TFTP Server

A TFTP Server is required in an IP Telephony system to distribute software
to the wireless handsets and WLAN IP Telephony Manager 2245. It can
reside on a different subnet than the Call Server and APs. The TFTP Server
can be located on either side of the firewall.

Firewall

The firewall is an optional element that is often used to separate the wireless
and wired domains.
