The communication with hardware drivers is performed using package interface procedures. The 
Init task controls the sequence of card initialization and synchronizes it according to the KSU and 
Base Station needs.
System management consists of several packages—each a set of functions providing a group of 
services. The main features are:
©Alarm management (send alarm, set alarm severity)
©Database services (add Base Station, change status)
©Configuration Interfaces (reset Base Station)
©Test Control (set loop back, start test, utilities and general services, such as set date and time, 
set LED)
©UTAM procedures
Changing Initial Configuration
It is highly recommended that you get the current configuration and save it to a file on the PC as 
the working copy. Then, open and edit the working copy – not the original file. Using this method 
ensures that the original configuration file is not corrupted while adding or editing existing data. 
Once the new information is saved, the RWIU uses the new data immediately.
Important!Sending configuration information to the RWIU overwrites existing information. 
Make sure that the sent data contains all of the required configuration information, 
not just the few additions or changes that were made.

Troubleshooting
This section describes troubleshooting tips for the Strata AirLink Wireless BSIA and RWIU 
systems. Problems are classified and cleared by replacing the malfunctioning unit and by 
performing operational tests in the sequences described in this chapter.
Important!Many wireless system features are assigned, enabled or disabled using software 
entries as described in “Install the Strata AirLink Manager Software” on Page 16-
19 (BSIA) and “RWIU System Installation” on Page 16-36 (RWIU). It is very 
important to verify that the programming is correct and functional before 
troubleshooting the hardware.
Before beginning diagnostic and troubleshooting tests, check the following:
©System power, polarity, and continuity
©BSIA or RWIU LEDs, boot sequence, and alarm relays
©Base Station LEDs
©Handset and batteries
©Strata AirLink and RWIU Manager reports
System Power, Polarity, and Continuity
It is important to check all power sources, polarity, and continuity before any other troubleshooting 
begins. Quickly check the LEDs. Check the polarity of the system by ensuring that all transmit and 
receive pairs are consistently wired throughout the system. Sometimes switching pairs at the Base 
Station solves a problem quickly.
Components
If only one system component has a problem, try replacing it with a known good one. For 
example, switch Base Stations, RWIUs, BSIAs, ALMs, or handsets to see if problems persist.
Communications
To check for communication errors (for example, serial port failure), perform a software version 
query of the Base Station from the software. If the system does not respond to the query, check the 
cables.
RF Link Termination
The handset can lose its signal from the Base Station because of reduced power, interference, or 
stepping out of range. Verify that the battery is fully charged and the handset is in range of a Base 
Station.
Noisy Circuits
If users complain about noisy circuits or problems with dial tone, try switching the user to another 
circuit on the office telephone system. If a circuit is not operating at all, use a installer test set to 
check continuity throughout a system.

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. For specific BSIA information, see “To measure the DC resistance” on 
Page 16-73, and for the RWIU, see “Measuring DC Resistance” on Page 16-85.
System Reset
As a last resort, sometimes resetting the system clears up system problems. Before resetting the 
system, collect as much information as possible in the current log file. Get traffic statistics reports, 
call status reports, line and Base Station status reports, and alarm reports, if available. Use the Save 
As command to save the log file.
Activation Code
If the UTAM activation code has not been uploaded, the Base Stations will not operate (refer to 
“Set Up Temporary Installation” on Page 16-9 for more information). Contact Strata AirLink 
Activation Desk at (949) 598-4980 for the code between the hours of 8:00 a.m. and 5:00 p.m. 
(Pacific Standard Time), Monday through Friday. Voice mail is available for messages after hours.
Base Station
The Base Station has five LEDs (see Figure 
16-31). Four LEDs on the left indicate error 
conditions during power on, reset, and during 
the diagnostic tests that run during normal 
operation. The green LED on the right is the 
power indicator. 
Power On/Reset
Table 16-22 explains how to interpret Base 
Station LED readings that occur during power 
on or reset. The LEDs must be read in 
combination to understand their meaning. The 
footnotes to the table contain troubleshooting 
suggestions.

SymptomsPossible Solution
Called party can hear but 
cannot be heard.
Conversation broken up.
Handoff clicks occur during 
conversation.The handset signal strength is inadequate. Try moving closer to a Base 
Station. If the problem is reported by many users, try moving the Base 
Station to a location that provides better coverage.
For best results the signal strength icon should show three to five bars. 
The (BER) test should report Good or Max results. See BER testing on 
Page 16-13 for instructions on how to perform this test.
Display does not contain date, 
time and signal strength.The handset is not locked onto a Base Station. Try powering off and on 
or moving to another location closer to a Base Station. 
NoteIt may take up to a minute for the full display to appear.
If the problem persists, check system and handset ID configuration. 
These symptoms could also occur if the BSIA, RWIU, or Base Station is 
being reset. Table 16-23 Base Station LEDs during Normal Operation

Off-hook icon ( ) flashes 
when &$// is pressed;
Handset operated correctly 
and now cannot make calls.The handset ESN is improperly configured. Fix this problem by: 
1. Reprogramming the handset with proper system and handset IDs.
2. Changing the handset ID configured for the handset to any valid ID 
not already in use.
3. Changing the handset ID in the User Database to match the ID 
programmed in the handset.
4. Making a call on the handset to store its ESN in the BSIA or RWIU.
5. Installing the ALM.
6. Performing a maintenance check (system maintenance busy) and 
loop start line status is activated.
Invalid ESN reported for 
handset (alarm).The same handset ID and system ID were programmed into two 
telephones and databases, and the handset ESNs were associated with 
the wrong analog line when the first telephone call was made. Fix this 
problem by:
1. Locating both handsets and correcting the databases.
2. Checking the handset ID configuration in both handsets to make 
sure they are correct. 
3. Changing the ID in the handset and making another call (corrects 
the ESN configuration for that handset).
4. Correcting the configuration for the handset that reported the invalid 
ESN. Follow these steps:
lOpen the User Database and change the handset ID 
configured for the handset to any valid ID not already in use.
lChange the handset ID in the User Database to match the ID 
programmed in the handset.
lMake a call on the handset to store its ESN.
No dial tone.Make sure the handset is locked and check the volume level. If the 
problem remains, the handset is not locked onto a Base Station. Try 
powering off and on or moving to another location closer to a Base 
Station.
Check the analog line with a installer’s test set to ensure the telephone 
system is operating properly. If it is, check the wiring between the BSIA 
or RWIU and the telephone system.
Check the BSIA, RWIU, or Base Station for a reset condition because 
this will interrupt the dial tone.
Weak or delayed dial tone.Check the handset volume level. Make sure to align the handset with the 
ear rather than mouth and don’t watch the display.
Consider using the predial method to make calls by dialing the number 
and pressing &$// (rather than pressing &$// and waiting for dial 
tone).
NO SERVICE! message.The handset is not locked and it is out of range or all eight channels of 
the Base Station are being used for other calls. Try powering off and on 
or moving to another location closer to a system Base Station.
Check the BSIA, RWIU, or Base Station for a reset condition because 
this will cause the NO SERVICE! message.
Reset the handset to the factory defaults. Table 16-24 Handset Troubleshooting
