1.2.1 DHCP (Dynamic Host Configuration Protocol) Server
For IP-PTs to communicate over a network, an IP address must be assigned to each IP-PT to identify its
locations on the network. While these addresses can be assigned manually at each IP-PT, it is also possible
to use a DHCP server.
A DHCP server automatically assigns IP addresses to IP-PTs when they are connected to the network. An
IP-PT then use the received IP addresses to register to the IP-EXT16 card.
Using a DHCP server allows you to centrally manage and automate the assignment of IP addresses.
Notes
• The Hybrid IP-PBX is not able to act as a DHCP server. To use the DHCP client function of IP-PTs,
a separate DHCP server is required on the network, as shown above.
• The IP address for the IP-EXT16 card cannot be assigned automatically using a DHCP server. This
IP address must be assigned manually by using KX-TDA Maintenance Console (PC programming
software of the Hybrid IP-PBX). For details, refer to "4.1 Programming the IP-EXT16 Card".
• An IP-PT cannot request IP addresses from a DHCP server on another LAN (connected through
IP network). An IP-PT can only receive IP addresses from a DHCP server on its own LAN.
Therefore, when IP-PTs are located on several LANs, a DHCP server is required on each LAN. If
a DHCP server is not present on the LAN, IP addresses for IP-PTs on that LAN must be assigned
manually.
