Call Server
The Call Server can be the Call Server of any Nortel Networks
Communication Server (CS) 1000 or Meridian 1 IP Telephony system
running CS 1000 Release 4.0 software.
DHCP Server
The existing DHCP Server can be on either side of the firewall, according to
the site administrator’s preference. The DHCP server is optional if the
wireless handsets and WLAN IP Telephony Manager 2245 are statically
configured.
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 Access Points. The TFTP
Server can be located on either side of the firewall.
Firewall
The firewall is an optional element which is often used to separate the
wireless and wired domains.
WLAN Handset 2210 and WLAN Handset 2211
The WLAN Handset 2210 and WLAN Handset 2211 use Voice over IP
(VoIP) technology on IEEE 802.11-compliant Wireless Local Area Networks
(WLANs). Access Points use radio frequencies to transmit signals to and
from the wireless handsets.
