In the
PARI Master IP Address text field
, enter loopback address 127.0.0.1.
4
If the base station shall be used without a network and a DHCP server, a static
IP address must be set. Do as follows:
Select LAN > DHCP. In the
Mode
drop-down list, set the DHCP mode to
"disabled"
.
Select LAN > IP. In the
IP Address
text field, enter an IP address, e.g.
192.168.0.1
5
Set base station A in deployment mode.
6
Set base station A as Sync master
7
Register one DECT handset in Base station A
8
Configure base station B as base station A using the same system ID, PARI and
SARI. Note: It is recommended to use different IP addresses
9
Set base station B in deployment mode.
10
Set base station B as Sync Slave.
11
Base station A shall be placed the first time on the planned location for the Sync
Master (should be in the middle of the site).
4.2 CHECK THE SPEECH COVERAGE FOR BASE STATION A
12
Check on the DECT handset that the signal strength is > -68 dBm which is the
normal case to get sufficient speech quality within each base station.
13
Verify that the speech quality is sufficient by listening on a call. When the off-
hook key is pressed, the speech is looped back. However, when the off-hook key
is pressed on an anonymous DECT handset a dial tone is heard and when a
digit is pressed the speech is looped back.
In certain environments, for example reflective environments (large rooms with
lots of metal), there might be a need for a considerable stronger signal strength
more than -68 dBm in order to get sufficient speech quality.
14
Mark on a map the position and the speech coverage for base station A.
4.3 CHECK THE SYNCHRONIZATION COVERAGE
15
Use the GUI web interface on base station B and check that the signal strength
from base station A to base station B is stronger than -83 dBm. If this is not the
case then you should consider to move base station B closer to base station A to
get a stable synchronization coverage for a longer time.
For
IPBS4x2/IPBS2
:
You can also check the synchronization by looking at the
LED on the base station
IPBS4x2/IPBS2
on page 13. For a
description of LED deployment indications, see the diagram in
13. When indicating no sync (LED flashing red and yellow) it might take some
additional time (10 to 30 seconds) to regain synchronization when entering the
sync coverage again.
