3 Setup of Terminals
This chapter describes step by step how to set up MINI-LINK terminals. Examples
of setup for different MINI-LINK configurations are given in section 3.5.
For the supervision to work, the MINI-LINK equipment must be interconnected
via the different communication channels (see section 4.1.2), and every
terminal within the sub-network must have a unique ID (identity). Each
terminal must also know the IDs of other terminals connected to its own
communication channels.
3
For further information on cabling, see the cabling section in MINI-LINK E
Installation Manual, MINI-LINK E Micro Installation Manual and in the user’s
manuals for MINI-LINK C and MkII equipment.
3.1 IDs
Within a network, every terminal must have a unique ID (identity) for the
message router to work properly.
A MINI-LINK E terminal is one side of a hop (consisting of the indoor parts
(MMUs and SMUs) and outdoor parts (RAUs)) or an SAU.
A MINI-LINK E Micro terminal is one side of a hop (a MINI-LINK E Micro
radio).
A MINI-LINK C or MkII terminal is a radio or an SMM.

Figure 3-1. Example of MINI-LINK E, E Micro, C and MkII terminal IDs.
An ID consists of a combination of four characters; digits (0-9), capital letters
(A-Z) or small letters (a-z). The first three characters can, for example, be used
to define the site, and the last character to define the terminal on the site.
The own ID of a terminal can only be set or changed with the PC connected to
the terminal or, for MINI-LINK E a terminal in the same access module. This is
for safety reasons, so as not to lose supervision contact by mistake.
3.1.1 Restricted IDs
The following IDs are restricted IDs that must not be used: TRMA, TRMB,
SMMA, SMMB and AAAA.
BBBB is reserved for non-existing equipment.

3.6 Example of Traffic Setup with Routing
Note: Traffic routing is guaranteed only for a configuration verified according
to the MINI-LINK E Planning and Engineering manual and when you consider
the prerequisites below and follow the instructions in section 3.2.3.
The following prerequisites apply to traffic routing:
- The MMUs and SMUs must have software version > R4.
- The back-plane in the AMM is optimized for a net with tree structure. To
fully use an AMM, the terminal with the highest traffic capacity should be
placed in the position with highest pos number in the AMM.
- Always route on the highest possible traffic rate level (on 8 Mbit/s level
instead of 2 Mbit/s level, for example).
- The traffic can be routed between the terminals on a 2, 8 and 34 Mbit/s level.
- The terminal configuration is based on the alternatives provided in AM Setup.
- The MUXes are defined in the AM Setup. In the Traffic Setup it is possible to
connect or disconnect the MUXes - this can only be done for SMU MUXes.
- 8 Mbit/s can be connected to the 2 Mbit/s connector on the front.
Below is an example on how to set the traffic routing in the Traffic Setup
window.
Traffic in to the node: 34+2 Mbit/s, 1+1
Traffic out from the node: 2x8 Mbit/s, 1+1
6x2 Mbit/s on the front

4.1 Network Supervision
The Control and Supervision System (CSS) in the MINI-LINK equipment
makes it possible to supervise a sub-network from any point in the sub-
network. Each MINI-LINK unit (except the MINI-LINK E RAU) is provided
with an RS-232 communication port, which gives access to the full range of
CSS utilities. With a PC connected to this port (the O&M port on
MINI-LINK E equipment and the TERM port on MINI-LINK C and MkII
equipment), you can read any alarm and status signal in the sub-network.
For the supervision to work, the MINI-LINK equipment must be
interconnected via the different communication channels (see section 4.1.2),
and every terminal within the sub-network must have a unique ID. Each
4
terminal must also know the ID of the remote terminal and the IDs of other
terminals connected to its own communication channels.
The ID of a near-end terminal can only be set or changed with the PC
connected to a terminal in the same access module. This is for safety reasons,
so as not to lose supervision contact by mistake.
It is possible to supervise several clusters connected to one sub-network. This
requires an RAC port (MINI-LINK E SAU).

With a modem, it is possible to supervise a far distant MINI-LINK sub-
network from a PC (see appendix).
Note: There is a practical limit of 200 terminals per sub-network.
4.1.1 Terminal Types
MINI-LINK E equipment is supervised as terminals; MMUs, SMU and RAUs
belonging to the same terminal, have a common ID. An SAU has its own ID.
MINI-LINK E Micro is supervised as a terminal, presented with one ID in the
Terminal list.
For MINI-LINK C equipment, each radio and SMM has a unique ID in the
CSS, and is supervised as a separate terminal.
SAU ID 0001
MMU ID 0002 Radio
RAU ID 0003
SMU SMM ID 0004 ID 0005

4.1.2 Communication Channels
The control and supervision data within a sub-network, is transmitted via
different communication channels, and can be supervised from any terminal in
the sub-network.
There are communication channels between the equipment on a site, as well
as between radios across the hops;
For MINI-LINK E equipment:
- The NCC (Node Communication Channel) transfers data between the units in
an access module. The Expanded Node Communication Channel transfers data
between max. two AMMs and one E Micro at the same site.
- The RCC (Radio Communication Channel) transfers data between the MMU
and the RAU.
4
- The HCC (Hop Communication Channel) transfers data between MMUs over
the hop.
- The EAC (External Alarm Channel) transfers data from the SAU in the access
module to other SAUs or MINI-LINK C and MkII equipment on a site.
- The RAC (Remote Alarm Channel) transfers data from other MINI-LINK
clusters (between SAUs), distributed through transmission lines.
For MINI-LINK C and MkII equipment:
- The IAC (Internal Alarm Channel) transfers data over the hop.
- The EAC (External Alarm Channel) transfers data between MINI-LINK C and
MkII equipment and SAUs on a site.

The MINI-LINK equipment has several failure detectors. When an event
occurs in the network, a notification message is shown on the left-hand side in
the status bar and the status for the network is updated. The notification
message remains in the status bar until a new notification message is logged.
The Status bar is also available when entering sub-windows and Terminal
windows.
The alarm notification shows the terminal ID. In the Alarm field in the
Terminal window for the terminal, the active alarms are presented graphically

4.4 Remote SW Upgrade
4.4.1 Introduction
This section describes how to use the Remote SW Upgrade functions in the
MSM program.
The Remote SW Upgrade is used to download and activate new CSS
software versions in any number of MINI-LINK E terminal units of the same
type.
The Remote SW Upgrade function requires CSS software version 5.0.
Remote SW Upgrade is divided in two sessions:
- A Remote SW Load session which loads a CSS software version in selected
units of the same type in one or more terminals.
The current status for the selected units and the load progress are presented
during the session, as well as the reason for any excluded units.
The result of the completed load session is saved as a Load Session file. The
saved load session can later be used for activation.
- A Remote SW Activation session which activates the new loaded CSS
software in selected units of the same type in one or more terminals.
The activation session can be started when the present load session is finished
or a saved load session file can be selected and used for the activation session.
The current status for the selected units and the activation progress are
presented during the session, as well as the reason for any excluded units.
Activation can also be performed for each unit separately in a selected
terminal.
State and indication of Remote Software Upgrade (RSU)
There are two RSU indicators; for detected RSU and RSU in progress (not
finished or finished). The status of the RSU session is shown in the status
bar.
The following states for RSU can be presented:
RSU detected – If RSU is started from another MSM, and at least one
terminal’s status indicates that it is under RSU.
RSU in progress – If RSU is started from own MSM and the RSU session is
not finished.
RSU finished – If RSU is started from own MSM and the RSU session is
finished.

95. 4-31 4 Network Management
4.4.2 Recommendations for Remote SW Upgrade
The user traffic will not be affected during a Remote SW Upgrade session.
The Remote SW Upgrade session will take 5 to 15 hours, depending on the
size of the load file and the number of selected units.
In order to minimize the risk of failure with the Remote SW Upgrade,
consider the following before starting a session:
- Start only one session in a sub-network at a time.
- Start the session when the sub-network is stable, with only a minimum of
disturbance.
- Start the session when the traffic is low.
- Start the session when the weather conditions are favourable.

Transmitting direction
The incoming signals from the MMU are demultiplexed in the cable interface.
The transmitting IF signal is amplified and fed to the microwave sub-unit for
modulation onto the RF transmitter oscillator. If the signal is missing, the Tx IF
Input Alarm is activated. The frequency of the transmitter is controlled in a
phase locked loop. An unlocked loop generates the Tx Frequency Alarm.
The transmitting RF signal is amplified, frequency multiplied and filtered. The
transmitter can be controlled by switching the final amplifier on or off. The
transmitter output power is measured and a low level generates the RF Output Level
Alarm.
For test purposes a sample of the transmission signal can be fed into the receiver as
an RF Loop (MINI-LINK 7-E, 8-E, 15-E, 18-E, 23-E and 38-E only).
All radio units have built-in variable attenuators which can be adjusted from
MINI-LINK Netman. In addition to variable attenuators, all RAU1 radios can
have fixed RF attenuators fitted inside the radio unit.
EN/LZT 110 5057 R2A

122. 5 MINI-LINK E Terminal 5-6
Receiving direction
The received RF signal is down-converted in two steps to an IF of 140 MHz.
The frequency of the receiver is controlled in a phase locked loop. An unlocked
loop generates the Rx Frequency Alarm.
A portion of the output IF signal is used as a reference in an AFC loop. If the
control signal is outside the range, Rx AFC Alarm is activated.
Additionally, a portion of the IF signal is fed to a calibrated detector to provide an
accurate receiver input level measurement.
The level is accessible either as analog voltage at the Alignment port on the RAU,
or in dBm through the CSS, in MINI-LINK Netman. A low receiver level generates
the RF Input Level Alarm or AGC Threshold Alarm.
The outgoing signals to the MMU are multiplexed in the cable interface.
Common parts
The common parts consist of the RAU Control and Supervision System (CSS). The
main functions of the RAU CSS are:
− Alarm collection, where collected alarms and status signals from the RAU are
sent to the MMU processor. Summary status signals are visualized with LEDs on
the RAU; a green LED indicating Power on (steady) or that the radio unit has
been replaced with a unit with faulty software setup (flashing), and a red LED
indicating faulty radio unit (flashing) or fault in another unit (steady).
− Command handling, where commands from the indoor units are executed. The
commands include transmitter control, channel frequency settings, output power
settings and RF-loop control.
− Radio unit control, where the RAUs internal processes and loops are controlled.
If the processor detects a software fault, it generates Proc Software Alarm. An
interruption during setup generates EEPROM Alarm. Other processor faults
generate Proc Hardware Alarm.

Transmitting direction
The traffic input signals are connected from the MMU front or from an SMU
through the access module backplate. If any of the active signals is faulty, Input
Alarm is generated. For test purposes the traffic input signals can be looped back
(MMU Tx Loops).
MMU 4x2/8 only: The four 2 Mbit/s traffic input signals are multiplexed into one 8
Mbit/s signal. If the 8 Mbit/s signal from the Multiplexer is faulty, Input Alarm is
generated.
Three different service types are multiplexed in the Radio Frame multiplexer for
transmission over the radio path;
- Traffic,
- Service channel and
- Hop Communication Channel (HCC).
This composite data stream is signal processed and pulse shaped to optimise
transmitting spectrum.
The modulator consists of a phase locked voltage controlled oscillator (VCO). The
oscillator is controlled from the far radio. If the modulation index is out of range, the
Mod Index Alarm is generated.
For test purpose, the IF Loop can be activated. It loops the signal after the
modulator to the demodulator in the receiving direction.

Receiving direction
The signal from the RAU is AGC amplified and filtered. It is then demultiplexed and
FEC corrected in the Radio Frame demultiplexer. The demultiplexer generates the
Radio Frame Alarm if frame synchronization is lost. The number of errored bits in
the traffic data stream is measured. These are used for performance monitoring and
BER detection. The BER Alarm is activated when the BER alarm threshold, which
is software setable, is exceeded.
If the received bit stream comes from a radio with an ID differing from the Far End
ID set, a Radio ID Alarm is generated. A Dmod Clock Alarm is generated if the
received data rate does not correspond to the internal data rate of the MMU.
AIS is inserted at the receiving direction in case of failure, see section 5.5.2. AIS
Received Alarm indicates that an AIS signal is received.
In 1+1 configurations, if the receiver fails to synchronise the received traffic signal
to the MMUs, Hitless Phase Alarm is activated to indicate that the 1+1 switching is
not hitless.
MMU 4x2/8 only: The incoming 8 Mbit/s signal is demultiplexed into 2 Mbit/s
signals. If the signal is lost, or there is a frame lock error on the signal, the System
Line Fault E2:1 Alarm or Frame E2:1 Alarm respectively are generated.
5
For test purpose, the traffic output signals can be looped back to the transmitting
direction (MMU Rx Loops). This is made in the traffic router.
Common parts
A microprocessor-based control and supervisory system, CSS, is built into the
MMU. Its main functions are to collect alarms, control settings and loop tests and
handle the bit error collection. The communication channels within a sub-network,
via which the CSS data is transmitted, are presented in section 4.1.2.
The processor communicates with the RAU and the remote MMU over the hop.
The RCC Alarm (Radio Communication Channel) indicates lost communication with
the RAU and the HCC Alarm (Hop Communication Channel) with the remote
MMU.
In 1+0 configurations the processor also handles the terminal communication with
the SMU holding the optional MUXes, and the communication with other terminals
in the AMM. Communication lost with the SMU is indicated by the NCC MUX
Alarm (Node Communication Channel). If communication is lost with the other
terminals within the AMM, the NCC Ext Alarm is generated.
If the processor detects a software fault, it generates Proc Software Alarm. An
interruption during setup, generates the EEPROM Alarm.
Processor faults not covered by the above, generate the Proc Hardware Alarm.

Figure 5-3c. SMU 16x2 block diagram.
Transmitting direction
In each multiplexer four 2 Mbit/s signals are multiplexed into an 8 Mbit/s signal. In
an SMU 16x2, the four 8 Mbit/s signals are further multiplexed into a 34 Mbit/s
signal. If any of the incoming signals is faulty, an Input Alarm is activated.
For test purposes, the traffic input signals can be looped back (SMU Tx Loops).
Receiving direction
The 34 Mbit/s signal in an SMU16x2 is first converted into four 8 Mbit/s signals.
The 8 Mbit/s signal is demultiplexed into four 2 Mbit/s signals. If the signal is lost,
or there is a frame lock error on the signal, the System Line Fault Alarm or Frame
Alarm respectively are generated.
For test purposes, SMU Rx Loops can be set to loop back the output traffic signals.
AIS is inserted at the receiving direction in case of failure, see section 5.5.2.
EN/LZT 110 5057 R2A

128. 5 MINI-LINK E Terminal 5-12
Common parts
A microprocessor-based control and supervisory system, CSS, is built into the
SMU. Its main functions are to collect alarms and control 1+1 switching and loop
tests.
In transmitter switching, transmitter is selected automatically on alarm information
from the transmitter section of the RAU or MMU, or manually from the MMU front
panel or PC.
There are two types of receiver switching; hitless switching, for fading, and
hardware switching. The hardware switching is controlled automatically from the
SMU processor or manually from the MMU front or the PC. The alarms that cause
automatic switching are listed in section 5.5.1.
In case of faults in the switching, the switch logic generates Switch Logic Alarm.
When the transmitter is replaced due to an alarm, Tx Switch Over Alarm is
generated. When the transmitter is replaced due to a request from the remote
terminal, Rem Tx Switch Over Alarm is generated.
The SMU processor communicates with the MMU(s) in the same terminal and with
other terminals in the AMM. Communication lost with the MMU(s) activates the
NCC Ra Alarm (Node Communication Channel), and with the other terminals the
NCC Ext Alarm. (See section 4.1.2 for the different communication channels in a
sub-network.)
If the processor detects a software fault, it generates the Proc Software Alarm. An
interruption during setup, generates the EEPROM Alarm.
Processor faults not covered by the above, generate the Proc Hardware Alarm.

EAC Port
The External Alarm Channel (EAC) ports are used for connection of the alarm and
control information to and from other MINI-LINK E access modules or
MINI-LINK C or MkII terminals on the same site, when building MINI-LINK sub-
networks. Lost communication on the EAC channel generates the EAC Alarm.
User In/Out
At the User In ports, the users’ alarms are connected to the MINI-LINK operation
and maintenance network. The User Input Alarm indicates an active User Input.
The User Out ports are used for control of the users’ functions via the MINI-LINK
sub-network. The User Out ports can also be set to connect summary alarms from
the access module to the users’ supervisory system.
Control and Supervision Processor
A microprocessor-based control and supervisory system, CSS, is built into the SAU.
It controls user input and output and service channel routing. The communication
channels within a sub-network, via which the CSS data is transmitted, are presented in
section 4.1.2.
The processor communicates with other processors in the access module via the NCC
(Node Communication Channel) and with other MINI-LINK sites through the EAC.
Loss of communication activates the NCC Ext Alarm and the EAC Alarm respectively.
5
If the processor detects a software fault, it generates Proc Software Alarm. An
interruption during setup, generates EEPROM Alarm. Other processor faults, not
covered by the above, generate Proc Hardware Alarm.
Digital Service Channels (Exp 1 and Exp 2 only)
The digital service channels (ITU-T Rec G.703 64kbit/s) are used for connection of
external equipment, and a failure activates the Service Channel Alarm.
Analog Service Channel (Exp 2 only)
The analog service channel is used for speech communication between MINI-LINK
sites. For connection to other AMMs on the same site, each SAU Exp 2 has two
branching ports which use the same connector as EAC (BR/EAC).
RAC (Exp 1 and Exp 2 only)
The Remote Alarm Channel (RAC) is used when MINI-LINK terminals on
different sites cannot be reached by air. The RAC has two types of interface, RS
232C for analog fixed lines (via modem) and digital ITU-T Rec G.703 for 64 kbit/s
fixed lines. A fault on the RAC channel activates the RAC Alarm.

132. 5 MINI-LINK E Terminal 5-16
5.2 MINI-LINK E Supervision
MINI-LINK E equipment is supervised as terminals, where a terminal is either
one side of a hop, or an SAU. The indoor parts (MMUs and SMUs) and
outdoor parts (RAUs) belonging to the same terminal, have one ID. In the
network list, the terminal is presented as one ID, whereas at terminal level the
different units in the terminal are presented separately.
The radio terminal types are:
MLE 1+0 Consists of one MMU, one RAU and, for traffic rates 8x2 and
17x2 Mbit/s, one SMU.
MLE 1+1 Consists of two MMUs, two RAUs and one SMU.
An SMU can be shared by two MMUs; either the two MMUs in a protected
hop, or two separate 1+0 terminals. When the SMU is shared between two 1+0
terminals, traffic alarms are presented in the terminal concerned, whereas
common SMU alarms are presented in both terminals.
The indoor part of the MINI-LINK E, the access module, can hold indoor units
for up to four terminals.
The SAU has its own ID and is shared between all terminals within an access
module.

5.2.1 Operation and Maintenance Facilities
There are various operation and maintenance facilities in MSM to perform on the
equipment at terminal level when the sub-network is run in normal operation. The
different facilities are controlled from the Terminal window.
For each radio terminal you can
- read alarm, performance and AGC (RF input level) data,
- activate P-mark during service work on the equipment (with P-mark activated, all
alarm signals are generated and can be read in the normal way, but notification
signals are inhibited),
- measure the traffic signals with an external instrument from test ports on the
front, without disturbing the traffic,
- switch transmitters and receivers (protected configurations only),
- etc.
For a SAU you can
- read alarm data,
- activate P-mark during service work,
5
- read environmental alarms (connected to User In),
- control remote functions, such as start air condition equipment (connected to
User Out),
- etc.
5.2.2 Fault Localization
The MINI-LINK equipment has several failure detectors. If a failure occurs in a
terminal, a notification message will be shown and one or more alarms in the
Terminal window will go active (see explanation in section 4.1.4). To help
locate the faulty terminal and unit, loop backs at several levels are available.

Near-end Loops (Tx Loops)
Near-end looping tests are used to find out if any of the units in the near-end
terminal is faulty (the SMU, MMU or RAU). The following near-end loop tests
are available (the numbers in brackets after each loop refer to the figure below):
SMU Tx Loops (N1). In the SMU the traffic signal to be transmitted is,
immediately at the input, looped back to the output (on the receiving side).
AIS is inserted at the far-end.
MMU Tx Loops (N2). The traffic signal to be transmitted is looped back at the
input of the MMU. AIS is inserted at the far-end.
IF Loop (N3). In the MMU the traffic signal to be transmitted is after being
modulated mixed with the frequency of a local oscillator and looped back for
demodulation (on the receiving side).
RF Loop (N4) (MINI-LINK 7-E, 8-E, 15-E, 18-E, 23-E and 38-E). In the RAU
a fraction of the traffic signal to be transmitted is shifted in frequency and looped
back to the receiving side. Note: Turn off the transmitter of the remote terminal
before activating RF loop, to avoid interference.

Figure 5-32. The Test Port window.
Each SMU and MMU has one test ports on the front panel, to which you can
connect test equipment. You can choose either to monitor or to route a traffic
signal.
• If you want to check the traffic signal, select the function Monitor and
connect an analyzer to Test Port Out.
The traffic signal will be lead to your analyzer without disturbing the traffic.
• If you want to measure for example bit error on the traffic signal, select the
function Route, set an RF loop or a loop at the far-end, and connect a
BER-meter to the test ports.
Note: Tx loop and Rx loop cannot be set in the same unit as the test port
connection; the latest action will remove the first. If for example the test ports on
an MMU are connected and after that a Tx loop on the BB1 signal in the MMU
is set, the test port connection will be removed. (The loops are presented on the
previous page.)

Transmitting direction
In the transmitting direction, Radio Frame multiplexing and modulation is
made in the Modem Board. If the modulation index, controlled from the far
radio, is out of range, the Mod Index Alarm is generated. An Input Clock Alarm
is generated if the internal data rate does not correspond to the received data
rate.
EN/LZT 110 5057 R2A

180. 6 MINI-LINK E Micro Terminal 6-4
In the transmitting direction, the traffic signal is amplified and fed to the
microwave unit for modulation onto the transmitter oscillator. If the signal is
missing, the Tx Input Alarm is activated. The frequency of the transmitter is
controlled in a phase locked loop. An unlocked loop generates the Tx
Frequency Alarm.
In the transmitting direction, the traffic signal is amplified and frequency
multiplied. The transmitter output power is controlled by adjusting the gain of
the power amplifier. The transmitter can be switched on or off by switching the
final amplifier. The transmitter output power is measured and a low level
generates the RF Output Level Alarm.
Near-end loop tests, Tx Loop and RF Loop, can be used for test purposes.
Receiving direction
The received RF signal is down-converted in two steps to an IF of 140 MHz.
The frequency of the receiver is controlled in a phase locked loop. An unlocked
loop generates the Rx Frequency Alarm.
The output IF signal is used as a reference in an AFC loop. If the control signal
is outside the range, Rx AFC Alarm is activated.
Additionally, a portion of the IF signal is fed to a calibrated detector to provide
an accurate receiver input level measurement (RSSI).
The Radio Frame demultiplexer generates the Radio Frame Alarm if frame
synchronization is lost. The number of errored bits in the traffic data stream is
measured. These are used for performance monitoring and BER detection. The
BER Alarm is activated when the BER alarm threshold, which is software
setable, is exceeded.
If the received bit stream comes from a radio with an ID differing from the Far
End ID set, a Radio ID Alarm is generated. A Dmod Clock Alarm is generated
if the received data rate does not correspond to the internal data rate.
AIS is inserted at the receiving direction in case of failure. AIS Received Alarm
indicates that an AIS signal is received.
A low receiver level generates the RF Input Level Alarm if the received RF
input signal level has dropped below the threshold for the receiver or the AGC
Threshold Alarm if the RF input level has dropped below the AGC threshold
value. The AGC threshold is set in Main setup.
Far-end loop test Rx Loop can be used for test purposes.
Common parts
If the processor detects a software fault, it generates Proc Software Alarm. An
interruption during setup generates EEPROM Alarm. Other processor faults
generate Proc Hardware Alarm.
If communication is lost on the HCC between the near-end and the far-end
MINI-LINK E Micro or split it generates HCC Alarm. Communication lost on
the NCC to any terminal on the NCC generates the NCC Alarm.
Loss of AC power supply to MINI-LINK E Micro generates the AC Alarm
(traffic can be maintained with battery backup).

operation. The different facilities are controlled from the Terminal window.
Note: The list below applies for a Control user only. The facilities for a View user
are limited and all functions below are not included (see section 1.5).
For each radio terminal you can among other things:
- read alarm, performance and AGC (RF input level) data
- activate P-mark (with P-mark activated, all alarm signals are generated and can
be read in the normal way, but notification signals are inhibited)
- measure the traffic signals with an external instrument from test ports on the
front, without disturbing the traffic
- switch transmitters and receivers (protected configurations only)

7.1.1 Operation and Maintenance Facilities
There are various operation and maintenance facilities in MSM to perform on
the equipment at a terminal level, when the sub-network is run in normal
operation. The different facilities are controlled from the Terminal window.
For each radio terminal you can
- read alarm, performance and AGC (RF input level) data,
- activate P-mark during service work on the equipment (with P-mark activated, all
alarm signals are generated and can be read in the normal way, but notification
signals are inhibited),
- read environmental alarms (connected to User In),
- control remote functions, such as start air condition equipment (connected to
User Out),
- etc.
For an SMM you can
- read alarm and performance data,
- activate P-mark during service work on the equipment,
- switch transmitters and receivers (protected configurations only),
- read environmental alarms (connected to User In),
- control remote functions (connected to User Out),
- etc.
7.1.2 Fault Localization
The MINI-LINK equipment has several failure detectors. If a failure occurs in a
terminal, a notification message will be shown and one or more alarms in the
Terminal window will go active (see explanation in section 4.1.4). To help locate the
faulty terminal and unit, loop-backs on several levels are available.
The SMMs are equipped with relay outputs for indication of bay alarms. These
relays can be connected to the user’s own supervision system.

• Click on the control button to open the sub-window.
The control functions for a MINI-LINK C or MkII radio terminal are:
P-mark
P-mark is a valuable facility during fault localization. With P-mark activated, all
alarm signals are generated and can be read in the normal way, but alarm
notification messages are inhibited. The severity of the terminal will be Warning
independent of alarm status.
Figure 7-19. The P-mark window.
Loops
All available loops are listed and can be activated/deactivated.
Figure 7-20. The Loops window.
The loop test facility is a helpful tool for localization of a faulty unit. Several
loops can be set to isolate the fault to one terminal.

RF Loop (MINI-LINK 15-C, MINI-LINK 15 MkII, MINI-LINK 23-C
and MINI-LINK 23 MkII only)
RF Loop shifts a sample of the transmitted signal in frequency and loops it back
into the receiver. The remote radio terminal will insert AIS on its outgoing traffic.
RF Loop cannot be activated from the remote side, since looping breaks the IAC
connection and would make it impossible to deactivate the loop.
Note: Turn off the transmitter of the remote radio terminal before activating RF
Loop, to avoid interference.

Using the Service Telephone for
SAU Exp 2
The service telephone is connected to the analog service channel, available in
SAU Exp 2.
The two-digit number for the telephone is set in MSM, in the Service Channel
setup.
Making a phone-call
To call a service telephone in the MINI-LINK sub-network, lift the handset and
dial the number for the telephone.
- Service telephones connected to MINI-LINK E equipment are assigned two-
digit numbers in MSM. Dialling ”23” routes the ring signal to the telephone
with number 23.
- Service telephones connected to MINI-LINK C equipment are assigned
single-digit numbers. They are set with switches in the telephone. Dialling
”23” routes the ring signal to the telephones with number 2 and 3.
- The # button on the telephone can be used to make all telephones in the sub-
network ring simultaneously (general call, group conversation).
The 0-9 and # buttons are the only buttons required for calling in the MINI-LINK
sub-network. The other buttons are not used in the MINI-LINK application.
Note: There is absolutely no call privacy or secrecy on the service telephone
network. Ongoing conversations can be listened in to and participated in simply
by lifting the handset.
Adjusting the sound level
The sound level in the phone is adjusted with the control on the right hand side
of the telephone.
The sound level of the ring signal is adjusted with two switches on the left hand
side of the telephone:
- The switch for adjustment of the tone.
- The switch for adjustment of the volume.
