8.10 Intelligent Base Stations
8.10.1 Detailed description
This notice describes the rules to follow for an installation comprising three or four DECT bases.
For a larger installation, a preliminary study must be carried out using coverage tools. The bases are
then installed according to the results of this study.
8.10.1.1 Connection
The Alcatel-Lucent 4070 IO is designed for internal installation in the building, while the Alcatel-Lucent
4070 EO is designed for external installation.
The 4070 EO IBS comes in a plastic box and is protected against temperature variation.
The 2 antennae are outside the box so that they both have the same signal reception.
Intelligent Base Stations (IBS) are fitted with a red LED that gives information about the state of the
Base Station:
•
Fixed LED:
1. Software downloading
2. Initialization phase, waiting for synchronization
3. Software problem, IBS stopped.
•
Fast blink: There is a problem with the line.
•
Short ON, long OFF: Running on 1 UA link.
•
500ms OFF, 500ms ON: Running on 2 UA link.
The IBSs can run and be powered remotely by the UA access (this is the most common configuration).
But they can also be powered by a power device. This is used when there are a lot of IBSs and the
system power cannot support all the connected IBSs.
A base station may be connected to 1 or 2 UA links (UAI boards) and allows 3 or 6 simultaneous
connections with DECT/GAP terminals.
The need for three or six communication channels depends on the number of cordless stations and on
the DECT traffic to be managed.
In the event of a two-cable connection:
•
use two interfaces neighboring a UAI board
•
use the odd-numbered interface for the master link and the other for the slave link.
Both cables should have the same length. The first interface of the system's UAI16 board should
not be used since the operator station uses those points.
