© Avitec AB
6/15/2004
8 (96)
COMMAND AND ATTRIBUTE SUMMARY
The repeater can be configured to measure the antenna isolation on a certain timepoint of the day
(configured using attributes AIE and AIT). If antenna isolation is too low (as configured with attribute
ALA AIM), an alarm is triggered.
For details about the antenna measurement, please refer to attribute ACT AIM in section “Miscellaneous
Command Attributes”
The antenna isolation is measured using the BCCH downlink and a second listener channel.
By default, downlink chain 1 and 2 settings are used for the antenna measurements. If only one chain is
enabled in the repeater, or if measurement should be done on other channels, this attribute can be used to
configure the alternate channels.
Format:
X Y
X is the BCCH channel, and Y is the second channel used in the measurements.
If configured to 0, same as configured in CHA 1 and 2 is used.
Example:
GET AIC
Reply:
0 122
means that BCCH channel used is the one used in chain 1, but the listener channel is 122.
Example:
SET AIC 46 51
configures the BCCH used during measurements to 46, and listener channel to 51.
Note! Antenna isolation is not measured in Fiber Optic repeaters and repeaters CSFT18922 and
CSFT91822.
2.4
AIE - Antenna Isolation Measurement Enabled
Attribute type: Read and Write
The repeater can be configured to measure the antenna isolation on a certain timepoint of the day
(configured using attributes AIE and AIT). If antenna isolation is too low (as configured with attribute
ALA AIM), an alarm is triggered.
For details about the antenna measurement, please refer to attribute ACT AIM in section “Miscellaneous
Command Attributes”
This attribute configures if the automatic measurement should be enabled or not.
Format:
X = 0 means measurement of antenna isolation is disabled and X = 1 means measurement of antenna
isolation is enabled.
Example:
GET AIE
Reply:
means that the repeater will measure the antenna isolation once per day.
Example:
SET AIE 1
disables the measurement.
Note! Antenna isolation is not measured in Fiber Optic repeaters and repeaters CSFT18922 and
CSFT91822.
2.5

COMMAND AND ATTRIBUTE SUMMARY
The repeater can be configured to measure the antenna isolation on a certain time point of the day
(configured using attributes AIE and AIT). If antenna isolation is too low (as configured with attribute
ALA AIM), an alarm is triggered.
For details about the antenna measurement, please refer to attribute ACT AIM in “Miscellaneous
Command Attributes”
This attribute replies with the status of last antenna measurement.
Format:
X = 0 means OK. X = 1 means antenna isolation is too low, or a failure was encountered (failure cause
can be read out with attribute LAR) during measurement of the antenna isolation.
Example:
GET AIM
Reply:
meaning that last antenna measurement detected that the antenna isolation was too low, or the
measurement failed.
Note! Antenna isolation is not measured in Fiber Optic repeaters and repeaters CSFT18922 and
CSFT91822.
2.6
AIP - Antenna Isolation Measurement Progress
Attribute type: Read only
The repeater can perform an measurement of the antenna isolation measurement, either at scheduled
timepoints, or upon user request by entering the command ACT AIM (for details about the antenna
measurement, please refer to attribute ACT AIM in “Miscellaneous Command Attributes”). Once the
antenna isolation measurement is requested, polling the AIP detects when antenna isolation
measurement is completed.
This attribute replies with the progress of current antenna isolation routine.
Format:
X = 0 means measurements are completed, and X = 1 means antenna isolation measurement is in
progress
Example:
GET AIP
Reply:
meaning that antenna isolation measurement is in progress.
Note! Antenna isolation is not measured in Fiber Optic repeaters and repeaters CSFT18922 and
CSFT91822.
2.7
AIT - Antenna Isolation Measurement Timepoint
Attribute type: Read and Write
The repeater can be configured to measure the antenna isolation on a certain timepoint of the day
(configured using attributes AIE and AIT). If antenna isolation is too low (as configured with attribute
ALA AIM), an alarm is triggered.
For details about the antenna measurement, please refer to attribute ACT AIM in section “Miscellaneous
Command Attributes”
This attribute configures at what timepoint of the day the antenna isolation measurement should be
performed.
Format:
HHMMSS

COMMAND AND ATTRIBUTE SUMMARY
HH is the hours (in 24 hour notation), MM is minutes and SS is seconds specifying the measurement
timepoint.
Example:
GET AIT
Reply:
031500
meaning that antenna measurement timepoint is 15 minutes past three in the morning.
Example:
SET AIT 170000
sets the time for measurement to 17 in the afternoon.
Note 1! Since antenna measurement might cause dropped calls (radio parameters are changed for 3-4
seconds), it is recommended to set the antenna measurement to be performed during low traffic
intervals.
Note 2! Antenna isolation is not measured in Fiber Optic repeaters and repeaters CSFT18922 and
CSFT91822.
2.8

Y determines whether an alarm requires to be acknowledged or not.
(When using data call, an alarm is considered acknowledged when the repeater has successfully logged
in to the OMC, and delivered the alarm. In case of SMS, an alarm is considered acknowledged when an
acknowledge message is received from the main address. The alarms can also be acknowledged with the
command ACT ACK when logged in locally or remotely. If an alarm is not acknowledged, it will be
retransmitted up to MNR (maximum number of retransmissions) times, with RCA (repetition cycle for
alarms) minute’s interval. Refer to attributes MNR and RCA.)
Y = 0 means Acknowledge required
Y = 1 means No acknowledge required
Z is a threshold indicator, indicating how thresholds are used for this particular alarm source.
Z = 1 means that both thresholds are used for alarm calculation.
Z = 2 means that lower threshold is used
Z = 3 means that upper threshold is used
Z = 4 means that thresholds are ignored, i.e. digital measurement.
Note! Changing parameter Z does NOT affect the measurement of the alarm source. Z is just an
indicator of how the measurement is done, and should NEVER be changed.
LLL is the value of the lower threshold used for alarm calculation.
UUU is the value of the upper threshold used for alarm calculation.
TTT is the time an alarm has to be in erroneous state before an alarm is triggered.

MAR - Minimum Alarm Repetition Cycle
Attribute type: Read and Write
© Avitec AB
6/15/2004
34 (96)
COMMAND AND ATTRIBUTE SUMMARY
If there is an alarm toggling between OK and ERROR, the controller will continuously send alarms to
the OMC, with the new alarm detected, and then directly end of alarm, causing the communications
interface between the controller and the OMC to be blocked for a long time. If lots of alarms are
received at the OMC, the operator must be able to send a message to disable the particular alarm at the
controller until service of the unit has been performed. The Minimum Alarm Repetition Cycle takes care
of this problem by defining a minimum time between two consecutive alarms from the same alarm
source. Typically the MAR should be set to a minimum of two or three times the time it takes for the
controller to report the alarm to the OMC.
Format:
X is the Minimum Alarm Repetition Cycle in minutes.
Example:
GET MAR
Reply:
meaning that the minimum time between two consecutive alarms is three minutes.

When a message (alarm, SMS-reply or report) is sent to the Avitec Element Manager, the message
contains a message number. This message number is increased for every message sent (except for alarm
and report retransmission). If the controller is communicating via SMS, all four addresses (as read by
attribute ADD) have their own counter.
The MSG attribute is used to receive the list of these four counters.
Format on getting parameters:
1 X 2 Y 3 Z 4 W
X, Y, Z and W are the individual counters 1 – 4.
Example:
GET MSG
Reply:
1 00167 2 03421 3 00032 4 00000
indicating the different counters for addresses 1 to 4.
Format on setting value:
X M
X is the counter to modify, and M is the new value.
X is from 1 to 4, and M is from 0 to 99999

COMMAND AND ATTRIBUTE SUMMARY
meaning that the controller requires an acknowledge message back from the OMC (if the individual
alarm source is configured for that).
Example:
SET SAC 1
changes the behavior to consider the alarm acknowledged when the message is sent successfully to the
SMSC.
Note! This configuration will work in conjunction with the other alarm attributes (ALA XXX, RCA and
MNR).
If for example SAC is set to “1”, and RCA is set to 3 and MNR 3, the controller will try to send the
message to the SMSC center up to 3 times with 3 minute intervals.
If the individual alarm source is configured to not require an acknowledge, it will only try to send it once
to the SMSC.

COMMAND AND ATTRIBUTE SUMMARY
3 Traffic Related GET and SET Attributes
The controller constantly measures all timeslots in the uplink paths of all the chains.
Every 15 minutes, the utilization is calculated and stored in a log. At a configurable time of the day, the
report can optionally be sent to the repeater OMC. The report consists of 96 intervals, each interval 15
minutes long. As soon as the report is sent away, OR after measurements of the first interval of the next
day is completed, the log is cleared.
The utilization is measured in percentage:
Utilization = (Number occupied timeslots) / (Number of available timeslots) * 100
Example:
A two-channel repeater is sampled for one frame. 9 timeslots are utilized, which means ”Number of
occupied timeslots” is increased by 9, and ”Number of available timeslots” is increased by 16.

configures whether the alarm relay should be affected by the alarm source.
X = 0 means alarm transmission enabled, but alarm doesn’t affect the relay output
X = 1 means alarm transmission disabled, and does not affect the relay.
X = 2 means alarm transmission is enabled, and alarm affects the relay output.
X = 3 means alarm transmission is disabled, but alarm affects relay output
Y determines whether an alarm requires to be acknowledged or not.
(When using data call, an alarm is considered acknowledged when the controller has successfully logged
in to the OMC, and delivered the alarm. In case of SMS, an alarm is considered acknowledged when an
acknowledge message is received from the main address. The alarms can also be acknowledged with the
command ACT ACK when logged in locally or remotely. If an alarm is not acknowledged, it will be
retransmitted up to MNR (maximum number of retransmissions) times, with RCA (repetition cycle for
alarms) minutes interval. Refer to attributes MNR and RCA.)
Y = 0 means Acknowledge required
Y = 1 means No acknowledge required
Z is a threshold indicator, indicating how thresholds are used for this particular alarm source.
Z = 1 means that both thresholds are used for alarm calculation.
Z = 2 means that lower threshold is used
Z = 3 means that upper threshold is used
Z = 4 means that thresholds are ignored, i.e. digital measurement.
Note! Changing parameter Z does NOT affect the measurement of the alarm source. Z is just an
indicator of how the measurement is done, and should NEVER be changed.
LLL is the value of the lower threshold used for alarm calculation
UUU is the value of the upper threshold used for alarm calculation.
TTT is the time an alarm has to be in erroneous state before an alarm is triggered.
Example:
GET ALA TEM
Returns:
0 0 3 000 060 5
This means that alarm is enabled and acknowledge required. Upper threshold is used in measuring the
alarm, , lower threshold not set (000), 60 (degrees) is the upper threshold and that the temperature has to
be higher than 60 for 5 seconds before an alarm is triggered.
Example:
SET ALA TEM 0 0 3 0 60 20

Measurement Channels) be changed.
The measurement is automatically performed by the following steps:
1.
Output is turned of in the repeater downlink paths, except in chain 1.
2.
Channel in chain 1 is optionally changed to the alternative BCCH channel.
3.
Channel in chain 2 is optionally changed to the alternative Listener channel.
4.
Output channel in chain 1 downlink is changed to the Listener channel.
5.
Since the BCCH in chain one is transmitted as the Listener channel, we measure the input signal on
the Listener channel. Antenna isolation can now be calculated as transmitted output power in chain
one – received input signal in chain 2.
6.
Compare the measured signal with the alarm threshold ( ALA AIM ), and, depending on
measurement result, generate alarm or end of alarm.
7.
All radio parameters are restored to the default.
The repeater can be configured to measure the antenna isolation on a certain timepoint of the day,
configurable using attributes AIE and AIT)
All measurements in the repeater will affect the alarm transmission, meaning that a user initiated
measurement (using command ACT AIM) will also generate an alarm if isolation is outside allowed
interval.
Lower Threshold:
This is treated differently in Frequency Shifting repeaters and conventional repeaters;
2- and 4-channel Conventional Repeaters:
The lower threshold determines how many dB above the gain settings in downlink chain one the
isolation must be.
Frequency Translating Repeaters:
The lower threshold shows the lowest absolute isolation in dB before an alarm is triggere.
Upper Threshold:
Not used.
Time Threshold:
This indicates how many times the antenna isolation should have been measured as outside allowed
interval before an alarm is triggered.
Note! Since the antenna isolation is scheduled for measurement once per day, it is recommended that the
value is set to one.
Example in Frequency Translating repeaters:
GET ALA AIM
Returns:
0 0 2 75 0 1
This means that alarm is enabled and acknowledge required. Lower threshold is used in calculating the
alarms. Lowest allowed antenna isolation is 75 dB, and the isolation needs to be outside allowed interval
in one measurement before the alarm is triggered.
Example in Frequency 2- and 4-channel Conventional Repeaters:
SET ALA AIM 0 0 2 20 1
This sets the alarm as enabled and that acknowledge is required. Lower threshold is used in calculating
the alarms. Lowest allowed antenna isolation is 20 dB above gain settings in chain 1 DL, and the
isolation needs to be outside allowed interval in one measurement before the alarm is triggered. If the
gain in the repeater is set to 84 dB, the isolation in this example must be at least 104 dB.
Note! Antenna isolation is not measured in Fiber Optic repeaters and repeaters CSFT18922 and
CSFT91822.

5 Miscellaneous Command Attributes
The following commands are available both from login and, when supported, via Short Message Service
(SMS). The commands can also be sent from the Avitec Element Manager and the Avitec Maintenance
Console
5.1
ACT ACK
Acknowledges alarm
Format:
ACT ACK X
X is alarm with message number X.
Example:
ACT ACK 42
Acknowledges alarm with message number 42
Requires Read and Write access when logged in.
Via SMS, this can only be performed by the Main Address
5.2
ACT AIM
This command is used to perform antenna isolation measurements.
Antenna isolation measurement is performed using a special feature in the LIMPA’s, allowing for output
channel to be shifted from the input channel.
Two channels are used, one BCCH channel, and one so called Listener channel. By default, these
channels are the ones configured in chain one and two, but can with attribute AIC (Antenna Isolation
Measurement Channels) be changed.
The measurement is performed by the following steps:
8.
Output is turned of in chain 2 of the repeater in the downlink path.
9.
Channel in chain 1 is optionally changed to the alternative BCCH channel.
10. Channel in chain 2 is optionally changed to the alternative Listener channel.
11. Output channel in chain 1 downlink is changed to the Listener channel.
12. Since the BCCH in chain one is transmitted as the Listener channel, we measure the input signal on
the Listener channel. Antenna isolation can now be calculated as transmitted output power in chain
one – received input signal in chain 2.
13. Compare the measured signal with the alarm threshold ( ALA AIM ), and, depending on
measurement result, generate alarm or end of alarm.
14. All radio parameters are restored to the default.
The repeater can be configured to measure the antenna isolation on a certain timepoint of the day
(configured using attributes AIE and AIT).
By default, downlink chain 1 and 2 settings are used for the antenna measurements. If only one chain is
enabled in the repeater, or if measurement should be done on other channels, this attribute can be used to
configure the alternate channels.
Typically this measurement takes around 3-4 seconds. Under normal circumstances, the GSM network
should be able to keep the call during this absence of radio signal, but in some cases the call might be
dropped.
If this measurement is requested remotely, the call might be dropped. In order to read out the last
measurement, use the command GET LAI (Last Antenna Isolation Measurement).

COMMAND AND ATTRIBUTE SUMMARY
Note 1! This command will return the command prompt directly, and the actual measurement will be
performed in the background. In order to get the last measurement, poll the GET LAI until time stamp in
the reply shows that the measurement is completed.
Note 2! Since Fiber Optic repeaters and repeaters CSFT18922 and CSFT91822 cannot oscillate,
measuring antenna isolation will not give a meaningful result. For that reason, automatic antenna
isolation is not by default enabled in these repeaters.
5.3
ACT CLO
Clears all entries in the alarm log.
Requires Read and Write access when logged in.
Via SMS, this can only be performed by the Main Address
5.4
ACT HBT
Heartbeat Request
Causes the controller to send a heartbeat immediately after logout. Can be used to synchronize the
heartbeat transmissions in the Element Manager.
5.5
ACT RCD
This command is used to perform a power cycle of the modem directly after the next logout from the
repeater is performed.
Note! The controller can also be configured to automatically turn off and turn on the modem once per
day. This feature can be used to ensure that the modem parameters when using for example GSM
modems contain the latest network parameters such as HLR update interval etc.
Attribute MPE is used to configure if automatic modem power cycling should be enabled.
Timepoint for when to power cycling the modem can be set with attribute MPT. In order to read out Last
modem Power Cycling timepoint, use attribute LPC.
5.6
ACT RHW
Performs a hardware reset of the active devices ( not including the controller)
5.7
ACT RSR
Resets the controller software, as if the power has been switched off and back on.
Requires Read and Write access when logged in.
Via SMS, this can only be performed by the Main Address
Note 1! If logged in, an automatic logout will immediately occur.
Note 2! Since the controller always sends End of Power alarm after power up, two alarms will be sent
away every time a reset is performed, end of Power 1 and end of Power 2.
5.8
ACT TRE
Test Relay Connection. For installation testing purposes, it is possible to test the open / close function of
the relay. This test procedure makes sure the relay is closed for 2.5 seconds, then opens for 10 seconds,
and finally closes for 2.5 seconds before going back to original state.
Note! During this test interval, the relay connection will be unaffected by all alarms.
5.9
ACT UPA
Use Primary Address.

COMMAND AND ATTRIBUTE SUMMARY
Causes the controller to force the controller back to primary OMC address, in case secondary address is
used.
6 Commands
The following commands are only available when logged in to the repeater, either via Local
Maintenance Terminal (LMT), or via a remote login over a modem.
6.1
ACCESS MODEM
If user is logged in locally, the user can directly send characters from the keyboard to the modem
attached to the controller.
When typing ACCESS MODEM, the controller will send all the characters typed directly out the modem
port. All characters replied back from the modem will go directly out the LMT port.
This command can, together with the modem manual, be used to troubleshoot specific modem
communication problems.
To abort an ACCESS MODEM session, press -C, or use the escape sequence  ‘---‘
. Note that the three ‘-‘ must be pressed within one second.
Note! When accessing the modem port the modem might be configured with “echo off”, meaning that
the characters entered will not be echoed back to the screen. In order to enable the characters to be
echoed back from the modem, please hit .
After that, type
ATE1
followed by .The modem should then reply with
OK
indicating that the echo is enabled.
6.2
CLEAR LOG
By entering this command, the alarm log in the controller will be cleared.
This is the same as using the command ACT CLO, as described in section Miscellaneous Command
Attributes.
6.3
CLEAR SCREEN
By entering this command, the screen will be cleared from old information.
6.4
HARDWARE
Displays a list of all the configured hardware devices in the equipment, including serial number,
software and hardware versions.
This command is also used to reconfigure the system after replacing a broken module.
Format:
HARDWARE REPLACE   [Article Number]
 is the serial number of the module that has been removed
 is the serial number of the new module
[Article Number] is used if a passive module, such as a distribution board or external interface board is
changed.
Example 1:
HARDWARE REPLACE 2J3A 3ASA
replaces the broken module 2J3A with the new module 3ASA.
