When traditional CSs are

KX-TCA175/KX-TCA275
PSs do not operate
properly.
•

when the CS status is
changed from Out of

•
IP-CSs are installed at a
remote site after installing
CSs at a local site, but the
IP-CSs do not operate.
•
After uninstalling some
CSs, other CSs do not
operate.
PROBABLE CAUSE
•
The clock signal source CS
is out of range for air
synchronisation.
•
PS is out of CS coverage
area.
•
Air synchronisation
between Master CS1 and
Master CS2 has failed and
each CS is generating its
own clock signal.
•
CSs are located too close
together in the same area.
•
The software version of the
traditional CSs is old.
•
It may take about 20 s for
the CS to start up after the
status has been changed
to In Service.
•
IP-CSs are not properly
synchronised with any CS.
•
Master CS is uninstalled.
SOLUTION
•
Locate the CS properly (refer to "5 Site
Survey Using the KX-TCA175/
KX-TCA255/KX-TCA256/KX-TCA275/
KX-TCA355/KX-TD7590").
•
Confirm the status of Master CS1 and
Master CS2 from Utility—CS Status
Monitor using the Maintenance
Console.
If all of values are displayed as "-",
restart Master CS1 and Master CS2
(refer to "13 Initialising the IP Cell
Station").
•
Reduce the number of CSs in the area,
or increase the distance between CSs
(refer to "5 Site Survey Using the
KX-TCA175/KX-TCA255/KX-TCA256/
KX-TCA275/KX-TCA355/
KX-TD7590").
•
Update the traditional CSs to version
5.000 or later.
•
Wait until the CS starts up.
•
When using only one IP-CS at a remote
site, assign the IP-CS as Master CS1.
•
When using multiple IP-CSs at a
remote site, establish air
synchronisation between IP-CSs.
•
Assign a Master CS again for air
synchronisation (refer to "Assigning the
Synchronising CSs").
