Product overview
Navigation This chapter contains information about the following topics.
•“Overview of SIP DECT” (page 9)
Overview of SIP DECT
You can use Nortel Session Initiation Protocol (SIP) Digital Enhanced
Cordless Telecommunications (DECT) to move without restriction about
your work site while conducting telephone conversations, using wireless
handsets. The Nortel SIP DECT system includes one or more DECT
access points (DAPs or basestations) connected to the TLAN.
A minimal SIP DECT system has the following five main components.
•Call Server
•Signaling Server
•PC with DAP controller software installed
•DAP
•handset
Use the following four tools to configure an IP DECT system.
•Element manager or overlay program for Call Server
•Element manager and, if required, Network Routing Service (NRS)
manager for Signaling Server
•IP DECT Configurator
•DAP manager IP DECT
Note: The IP DECT Configurator and the DAP manager IP DECT are
available as a part of the DAP controller software package.
The following software releases are required on the main system
components.

10 Product overview
•Call Server, Release 5.5
•Signaling Server, Release 5.5
•DAP software 4910b414.dwl or later
•DAP controller 4.1 or later (PC software)
You can connect IP phones to the TLAN, connect TDM phones to the
Call Server, Voice Gateway Media Cards and other required cards in Call
Server. Use Voice Gateway Media Cards for IP-to-TDM calls and for
conference calls involving IP phones or DECT handsets on basestations.
The configuration can also include a PC with DECT Messenger to provide
the DECT messaging service on SIP DECT.
Note: For SIP DECT to function properly, you must install a dedicated
Signalling Server running the SIP Gateway application. Other
applications, such as H323 Gateway, NRS, and IP Phones, can be used
on the same Signaling Server without limitations.
Use the Dynamic Host Control Protocol (DHCP) server or the Trivial File
Transfer Protocol (TFTP) server unless you use a DAP configuration
without DHCP or TFTP. You can configure the system to use two separate
servers; one for DHCP and the other for TFTP. If the system requires
DAP configuration without DHCP or TFTP, the DHCP or TFTP server is
required during installation or configuration changes.
Figure 1 "SIP DECT configuration" (page 11) shows a general SIP DECT
system configuration.
