PROBLEM
•
Noise is frequent while
using the PS.
•
Conversations disconnect
while using the PS.
•
There is noise during a
phone call.
•
Call handover is not
working.
•
"NO SERVICE" is displayed
on the PS's screen.
When traditional CSs are
assigned as Master CSs:
•
IP-CSs reset frequently.
•
KX-TCA175/KX-TCA275
PSs do not operate
properly.
•
PS stays out of service
when the CS status is
changed from Out of
Service to In Service.
•
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
•
PS is out of CS coverage
area.
In LAN synchronization case:
•
LAN synchronization to
Master CS has failed.
In air synchronization case:
•
The clock signal source CS
is out of range for air
synchronization.
In air synchronization case:
•
Air synchronization's
Master CS1 and Master
CS2 has failed and each
CS is generating its own
clock signal.
•
Metallic materials in the
surrounding structure are
interfering with the signal
received by the PS.
In air synchronization case:
•
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.
In air synchronization case:
•
IP-CSs are not properly
synchronized with any CS.
In air synchronization case:
•
Master CS is uninstalled.
SOLUTION
•
Locate the CS properly (refer to
"3.3 Site Survey").
•
Check the network configuration (refer
to "5.3 Recommended Network
Configuration").
•
Diagnose the network configuration
with IP Terminal Maintenance Console
(refer to "5.12 IP Terminal
Maintenance Console").
•
Locate the CS properly (refer to
"3.3 Site Survey").
•
Confirm the error log from Utility—Error
Log—Minor using the Maintenance
Console. If "369 IP-CS Handover
error" is displayed for the error log,
restart Master CS1 and Master CS2.
•
Install an additional CS where the
signal interference is worst.
•
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
synchronization between IP-CSs.
•
Assign a Master CS again for air
synchronization (refer to "Assigning the
Synchronizing CSs").
