DECT Installation
4.1
Introduction
The ipLDK-20 can be equipped with a WTIB(Wireless Telephone Interface Board) or a WDIB (Wireless
Telephone and DKT Interface Board) which will support DECT installations with single or multiple (max.
4/WTIB or 4/WDIB) Base Station configurations. DECT installation is a 5 step process:
1.
Install the WTIB(WDIB) in the ipLDK-20
2.
Identify the Base Station locations
3.
Install the Base Stations
4.
Subscriber DECT Terminals
5.
Register DECT users and terminal.
Installation of the WTIB(WDIB) is covered in section 4.2. Location and installation of Base Stations is
accomplished in accordance with the GDC-345TB CRS manual. DECT Terminals are subscribed and
registered in accordance with the GDC-345H/400H Wireless Terminal User Guide.
The WTIB(WDIB) provides the standard interface between the ipLDK-20 and DECT network. The
WTIB(WDIB) provides three or four wireless terminal interface circuits for connection to Base Stations
that can support up to 16 wireless terminals.
The following equipment is required to connect the wireless system:
Base Station
The base station should be installed indoors and protected from surge because it is
designed for indoor station.
GDC-400B
Each base station provides similar coverage for a particular area call as a cell, and supports 4
simultaneous calls (4 traffic channels).
