Battery
Table 16-26 lists symptoms of battery problems and possible solutions.
Charger Base
The Charger Base charges the handset and a spare battery. Do not have to remove the battery from 
the handset to charge it. The LEDs indicate the status of the charging process as shown in Ta b l e  
16-27.
Table 16-26 Battery Troubleshooting
SymptomPossible Solution
Battery has reduced talk/standby 
time.Try discharging and recharging the battery using the instructions on 
Page 16-73. The handset has been left unpowered for a long period 
of time and has drained.
Make sure users are not removing batteries from the charger base 
before the green LED appears. The handset battery strength icon 
shows full power after a short period of charging.
Complete the full charging cycle before using the batteries. Users 
should also use the handset during the day and recharge it at the 
end of the day, rather than performing intermittent charging during 
the day.
Charger has green flashing LED.Try recharging the battery. If the problem continues, replace the 
battery.
Table 16-27 Charger Base LED Indications
LEDStateMeaning
RedSteady Battery is rapid charging.
FlashingInternal battery fault. Charge the battery again. If the problem 
persists, replace the battery.
GreenSteady Battery is charged and ready.
FlashingBattery is charged, but it could have reduced standby/talk time. 
Try repeated rapid charging to rejuvenate the battery. Replace 
the battery, if this fails to remedy the situation.
AmberSteadyThe charger is evaluating the handset or battery state, or waiting 
for one battery to complete charging.
FlashingShort circuit or over-discharged battery is detected. Make sure 
contacts are clean and allow the battery to remain in the charger 
until rapid charging starts and completes.
Amber/green Alternate flashing Battery is discharging.

BSIA System
Reports
Strata AirLink Manager generates reports with troubleshooting information. Some of the reports 
are:
©Alarm conditions
©Traffic statistics
©Line, channel, and call status
Analog Line Continuity
To check the analog line continuity throughout the system,
 use an installer test set at individual 
MDF/IDF locations. Check for any bridge taps on the Base Station transmit/receive cables and 
remove. Check all punch downs and cable connections.
DC Resistance
The distances between the system and its Base Stations (see Table 16-28), whether using line 
power or a local power supply, can be exceeded during an installation. The distances are reflected 
in the resistance of the line.
lTo measure the DC resistance
1. Use a digital multimeter that has resistance measuring capability in ohms and a basic accuracy 
of better than one percent.
2. Use an RJ-11 female-to-female line adapter.
3. Ensure that all permanent wiring is done and all primary protectors are installed, if required. 
For information on primary protection requirements for UL1459 compliance in the United 
States, see “Primary and Secondary Protectors” on Page 16-91.
4. Disconnect the BSIA from power.
5. Disconnect the 25-pair cables from P1 and P2 on the BSIA.
6. Disconnect the transmit and receive cables from the Base Station and connect them into each 
end of the RJ-11 line adapter.
7. Set the multimeter to the ohms scale.
8. To check the distance to Base Station 1, connect the multimeter probes between pins 20 and 46 
of the 25-pair cable that connects to P1 on the BSIA. If no reading or a high resistance is 
reported, measure between pins 20 and 21. A reading should register at only one of the pairs 
and must be less than the values listed in Table 16-28.

9. Based on which pins returned a valid reading in Step 8, check readings between the following 
pairs:
©Valid reading pins 20/46 – measure pins 21/45
©Valid reading pins 20/21 – measure pins 45/46
The readings between the measured sets of pins should be similar.
10. To check the distance to Base Station 2, connect the multimeter probes between pins 24 and 
50. If no reading or a high resistance is reported, measure between pins 24 and 25.
NoteA reading should register at only one of the pairs and must be less than the values listed in 
Table 16-28.
11. Based on which pins returned a valid reading in Step 10, check readings between the following 
pairs:
©Valid reading pins 24/50 – measure pins 25/49
©Valid reading pins 24/25 – measure pins 49/50
The readings between the measured sets of pins should be similar.
12. If the multimeter reports no reading or high resistance, check the readings between any of the 
other pins specified in Steps 8~11.
If readings after performing Step 9 are correct, the transmit and receive pairs are probably 
reversed or shorted somewhere in the installation. If not, there are open connections 
somewhere in the installation; check and correct all punch-down connections and repeat Steps 
8~11.
Status Window
To diagnose problems, there are several reports available that are:
©Base Station channels status
©Loop start lines status
©Call status
©Critical alarms
A software query can be performed also, or as a last resort, the BSIA can be rebooted from the 
Status Window.

Critical Alarm Relay
When a critical alarm is detected, a relay on the BSIA is triggered and LED S3 flashes. The relay 
activates an external alarm, if one is installed (see installation instructions and specifications in 
Step 3 on Page 16-16).
To reset the alarm relay and determine the cause of the critical alarm, check the critical alarm 
report in the Strata AirLink Manager. Checking the critical alarm report also stops the flashing 
LED.
LEDs
There are LEDs on the BSIA (controller) that give continuous system status and assist in 
diagnosing symptoms. When the BSIA system is powered on, all BSIA LEDs except for PWR, 
RLOS1, and RLOS2 go through these changes:
©LEDs are lit for one second to show that they all work.
©LEDs turn OFF for a brief moment.
©LEDs light again.
©Each LED is turned OFF as the LED passes the test.
©If an LED remains lit after the boot tests complete, one or more hardware integrity tests have 
failed. Call processing software usually starts even if some of the tests fail, although some 
failures prevent call processing software from starting.
©The MASTER LED remains lit during boot up because it does not respond to a boot test.
©The PWR LED is always lit when the BSIA has power. The RLOS LEDs flicker during boot 
tests and are lit when there is a problem with Base Station connections.
Table 16-30 explains the meaning of the LED states during boot up and normal operation.

Station 2 are busy.
5 RLOS2 RedLoss of synchronization occurs on Base Station 2 because of poor
