Design Guide for the Alcatel
OmniPCX
Enterprise – Mobile IP Touch
OmniAccess 70
Flexible multifunction Access Point provides
simultaneous access to both 802.11a and 802.11b/g
networks. Supports built-in and external special
purpose antenna.

Alcatel openly recognizes the challenges faced by customers with existing 802.11 network implementations.
For this reason, Alcatel also seeks to support Mobile IP Touch - Voice over Wireless Local Area Network
solutions on a variety of approved third-party infrastructure architectures. Infrastructure vendors such as
Aruba, Cisco (former Airespace product suite), Colubris and D-Link can possibly be used in lieu of Alcatel’s
OmniAccess WLAN products. Solutions leveraging third-party Wi-Fi infrastructures (such as those previously
mentioned) must be reviewed and approved by Alcatel’s Bid Desk (SDP) for applicability and support.

Server Elements (DHCP, TFTP, Management)
1.1.4.1.
DHCP Server
Customers have two IP address allocation schemes to choose from for MIPT handsets, static mode and
dynamic mode. Static mode operation is very simple and requires no expanded explanation. Terminals are
simply programmed manually with IP addresses, subnet mask, default gateway, TFTP server, H.323
gatekeeper and SVP Server information. Optionally, MIPT Terminals can be configured in a dynamic mode
via standard DHCP server options.
Dynamic mode is recommended due to ease of use and speed of reconfiguration. For a number of reasons,
the DHCP Server function can not currently be hosted by the OmniPCX or SVP Server. A dedicated external
DHCP server is recommended for all MIPT VoWLAN solutions. Alcatel does not currently offer the DHCP
Server hardware platform and recommends the customers or business partners source this equipment from
their usual PC Server supplier.
Alcatel has validated the following DHCP Server software platforms for use with MIPT VoWLAN solutions.
Validated DHCP Server software platforms.
Windows 2000 (Server)

Important remark:
In addition to standard and common parameters (IP Address, Subnet Mask, Default Gateway
IP Address, TFTP Server IP Address), the external DHCP server must be able to provide the MIPT
terminal with the IP addresses of the SVP Server and H.323 Gatekeeper. This makes the
optional DHCP fields for “Vendor Specific Options” mandatory for use with MIPT handsets. For
Windows 2000 Server, the Vendor Specific Option fields are known as “Special Option N°151”
(for the SVP Server) and “Special Option N°154” (for the H.323 Gatekeeper).
