2 The WIMAN Command Line Level
Introduction to WIMAN technology
The WIMAN product series provides a powerful new technology for the design of flexible data networks. Integrating a multitude of innovative and optimized methods and communication
protocols, we’ve created a wireless network technology, which
is available for various applications such as campus networking,
high speed access for Internet users, and cellular data networks
in conurbation areas, etc.
In contrast to other available wireless products, the WIMAN
product line integrates the demand for an economic system with
high data rates, a high range and efficient utilization of the frequency-spectrum. The WIMAN System utilizes the most modern spread spectrum technology without using any further encoding algorithm, and features higher security and noise immunity than other existing systems. Applying the frequency hopping technique in combination with an intelligent transmission
control algorithm, the ISM frequency range between 2.4 and
2.4835 GHz is optimally used.
The interfaces provided by the WIMAN unit to attach to the
customer's terminal equipment complies with the international
X.21 and V.24/RS232/RJ45 standards allowing a direct connection to any standard personal computer, workstation or mainframe system. For hooking up wired networks (LAN, MAN,
WAN), there are various routers available in the form of hardware or software solutions.
The WIMAN product line provides users with the benefits of
high performance and speed in a wireless modem. WIMAN is
easily distinguished from other transmission systems through
several remarkable features:
7 / 87l
2 The WIMAN Command Line Level
1.1 Transmission Speeds / Frequency Range
At present, wireless data network technology can be divided into
two categories: The first category consists of wireless modems
with a small transmission bandwidth. These products are used
for company networks, cellular networks, CDPD (Cellular
Digital Packed Data) or GSM (Global System for Mobile communication) networks. The second category consists of wireless
modems with large bandwidth in the ISM range (Industrial Scientific Media, frequency range around 2,4 GHz), such as wireless LAN products.
It is possible to cover a large area with the narrow band systems.
Some systems are even able to cover a complete country. The
other LAN products specified above operate with substantially
higher data transmission rates; however, the range of these systems is limited to approx. 300m/900ft. Therefore, the area of application is strongly reduced.
The WIMAN technology offers the advantages of both the narrow band systems and the broadband systems. With a clear line
of sight between the antennas, data can be transmitted between
two WIMAN radio modems with a rate of up to 2048 KBit/s (at
the data interface) / 512KBit/sec at the wireless interface in duplex operation over a distance of up to approx. 40km/25miles
(FCC version) or up to approx. 5km/3.2miles (ETSI version).
Furthermore, WIMAN systems are deployed in a highly scalable
manner similar in nature to a cellular structure. Therefore, it can
overcome some of the need for direct line-of-sight.
8 / 87
2 The WIMAN Command Line Level
1.2 Frequency Hopping Procedure
All WIMAN radio modems operate with the modern frequency
hopping procedure. With this procedure, the RF-channel is
changed in very short intervals (all 8 ms). A total of 80 nonoverlapping radio channels are available.
WIMAN takes advantage of these 80 channels, each with 1
MHz of bandwidth, by use of spread spectrum technology (frequency hopping).
The WIMAN radio modem transmits information packages that
hop from one frequency to another, not staying longer than 8 ms
in a frequency range.
As data packets are transmitted and received, the ISP selects the
order of the channels, producing a truly secured line of data.
This remarkable feature yields the following important advantages:
•
High security against eavesdropping due to fast changes
of the channel,
•
Resistance to jamming,
•
Protection against other RF-systems in the same frequency band,
•
High performance with high efficiency,
•
Possibility of parallel operation of WIMAN connections
by use of different frequency-hopping patterns.
1.3 WIMAN Network Topology
With the WIMAN technology, bonding can be structured in a
simple point-to-point connection, but it is also possible to set up
various other network topologies. The WIMAN product series
consists of three different wireless WIMAN radio-modems:
WIMAN STAR: wireless base station for public and private
point-to-multi-point networks.
WIMAN ACCESS: wireless access node for public and private
point-to-multi-point networks,
WIMAN LINE: wireless point-to-point connection between
two computers or computer networks.

2 The WIMAN Command Line Level
1.4 Basic WIMAN Topologies
As previously mentioned, the WIMAN technology is not limited
to point-to-point connections. Different network topologies can
be structured. The following chapter introduces some simple
network configurations using the WIMAN units to illustrate
some of the features of each configuration.
1.4.1
Point-to-Point connections with WIMAN LINE
WIMAN LINE radio modems enable point-to-point connections
between local area networks, data terminals or individual personal computers. In general, the WIMAN LINE can replace a
wire communication or a zero-modem cable. At present the
WIMAN LINE supports duplex data transmission rates of 256
kBit/s at 2FSK

1.4.2
Cellular Networks using WIMAN STAR and WIMAN
ACCESS
One of the outstanding features of the WIMAN series is its ability to support point-to-multi-point networks with technically
matured distribution of load between the individual ACCESS
devices (load balancing).
Figure 2 shows a typical network environment.

and WIMAN ACCESS
This network configuration can be used as a wireless connection
to the Internet.
The current software-Version supports up to 9 WIMAN
ACCESS per WIMAN STAR. They can be configured to meet
higher density of traffic in the networks by use of several synchronized parallel WIMAN radio modems.
Avoid errors by synchronization of the WIMAN units (see
chapter 4.5 on page 53).

2 The WIMAN Command Line Level
1.5 Transmission Protocols
1.5.1
Frame Relay
The WIMAN system supports the Frame Relay protocol widely
used at many Telephony companies.
It operates smoothly in Frame Relay networks and enables the
application of commercial Frame Relay compatible Router as
switches on the STAR- and the ACCESS side.
Except for the supply of an Internet access, it is additionally
possible to use the WIMAN Frame Relay system for telephony
uses. Therefore, commercial Frame Relay multiplexers from
companies such as RAD, NUERA, CISCO, etc. can be used.
The Frame Relay support is a software-configurable feature and
is starting from the software-Version T.05. This software version does also support leased line functionality.

2 The WIMAN Command Line Level
The WIMAN Command Line Level
The operating system of the WIMAN radio modem has an integrated command line interpreter ("Shell") for configuration of
the WIMAN. Input and output is visible on the input or outputwindow of a PC terminal program (e.g. TELIX, ZOC).
So that communication between the terminal program and the
WIMAN can take place, the communication parameters of the
terminal program and the WIMAN must correspond.
The configuration of the WIMAN radio modem is executed with
instructions on the command line level (“Shell”). There is no
distinction between upper- and lower case characters (except for
passwords).
The command line level can be accessed via different interfaces.
Successful locking on the command line level is acknowledged
by display of the command line prompt. The factory setting of
the command line prompt is WIMAN II >.
The user may personalize the command line prompt (e.g.
DEVICE 1:).
2.1 Authorization Levels
The command line level has two different authorization levels
that differ in the number of changeable parameters. Therefore,
the WIMAN radio modem may be configured by diversely
qualified and permitted persons (e.g. user, Provider).
The last character of the command line prompt displays the
authorization level you are in at that time.
The authorization levels are represented as follows:
•
Authorization level 1 WIMAN II >
•
Authorization level 2 WIMAN II #
Each authorization level can be protected with a different password. However, a password for authorization level 2 is always
needed.
13 / 87l
2 The WIMAN Command Line Level
2.2 Passwords
Passwords serve to protect the WIMAN from unauthorized access to the command line level in the different authorization levels. All passwords must have a length from four to eight characters. For the passwords the following characters may be used:
" a... z ", " A... z ", " 0... 9 ", " - ", " @ ", "?", " \ ", " [ ", " ] ", "
< ", " > ".
NOTE:
The WIMAN DOES acknowledge case sensitivity characters for
passwords.
Attention
Typing in of any other characters than the ones mentioned above
may lead to a reset of the WIMAN shell.
If no password is assigned for the authorization level one, the
command line appears when the WIMAN is switched on. Otherwise you are asked to enter a password to access the command
line level one.
A password for authorization level two is always required. This
password cannot be deleted, however it is possible to modify
this password.
In case of a false configuration or a forgotten password in the
lowest authorization level (e.g. user authorization level) qualified personnel are needed to access the unit (e.g. Provider). It is
possible to gain access directly to level two by entering the designated password for that level.
With suitable instruction (see chapter 3.5.1, on page 40) you can
reset the password for authorization level one.
If, for any reason, you are unable to arrive at the necessary
authorization level any longer and you are thus closed out of the
device, it is possible to gain access with a master password. The
master password can only be used after the third unsuccessful
access attempt and can only be made via the serial interface.
Further information on this issue can be obtained from your
WIMAN Distributor.
Attention:
The input of the master password can be executed exclusively
over the RS-232 port and results in resetting of all parameters to
their factory settings. A reconfiguration of the device will be
necessary afterwards.
14 / 87
2 The WIMAN Command Line Level
2.3 Operation Modes
On the command line level, the following operating modes are
differentiated with respect to each authorization level:
•
Command mode and
•
Configuration mode.
In command mode you can view the accepted parameters of the
present configuration (current config) as well as give the accepted commands for this mode and authorization level (see
Chapter 2.6.1 on page 25).
In configuration mode you may change only the parameters allowed for that specific authorization level.
The system software indicates these parameters as “new configuration” (new config). You may render certified instructions
for this level and this mode.
Figure 4 shows how to switch between the different authorization levels and operation modes.

2.4 Configuration Data
The configuration data (values of the adjustable parameters) is
classified into the following three types:
•
New configuration (new config),
•
Present configuration (current config) and
•
Non-volatile configuration (boot config).
Figure 5 shows the connections of the three different types of
configuration data.

Configuration data
The new configuration is created by modification of the parameters in the configuration mode (see Chapter 2). This has no
effect on the current operation. It is possible to produce a new
configuration by manually changing the parameters or by reading-in a parameter text file. In the parameter text file comments
may be inserted at the start of a line or after an instruction (See
Chapter xxx on page xxx).
The present configuration consists of the parameters used by
the system at that time. This configuration can be saved as a text
file.
The non-volatile configuration consists of the parameters
called on and made the present configuration at a strat or restart
of the device. Modified parameters (new configuration) can either be taken over (transfer for present configuration) or rejected
by a query when leaving the configuration mode.
The up-to-date parameters (present configuration) can be permanently taken over by a further query when leaving the command mode (transfer into the non-volatile configuration) or
maintained only up to the next restart.

2.5 Configuration Parameters
The WIMAN radio modems are delivered with a factoryinstalled standard setup. To adjust the WIMAN to your specific
requirements you can modify different parameters (depending
on the authorization level).
The configurable Parameters are classified into the following
groups:
•
Parameter for the wireless interface,
•
Parameter for the serial interface,
•
Parameter for the network,
•
Other parameters.
All parameter can only be changed in the configuration mode of
the appropriate level.
2.5.1
Parameter for the Wireless Interface
The following parameters affect the wireless interface and serve
to set up the network configuration. These parametersalso set up
countermeasures against possible disturbances in the operating
frequency band.
Destination
The parameter destination determines the destination address of
the WIMAN, to which all data will be sent.
Note:
This setting is only available on WIMAN LINE units and is not
used on WIMAN STAR and ACCESS units.
FTab
Authorization Level:
Preset value:
Scope:
0 ... 250
The parameter FTab determines the frequency-hopping pattern
between the 80 channels. Each WIMAN radio-modem comes
with a factory installed frequency-hopping pattern that cannot be
changed. However, it is possible to create a second frequencyhopping pattern to be used in place of the standard one. In this
case the new pattern can be set with FTab.

The parameter LoopData sets the hexadecimal value to be sent
in a LoopTest.
Authorization Level:
Preset value:
FFFFFFFF
Scope:
00000000 … FFFFFFFF
The parameter LoopMode determines, which bit pattern and
frame lengths are to be used with the independent back loop test
(see loop test below). This parameter is not available on STAR
devices.
It is possible to set the values normal, load, long and high. The
values function as follows:
•
Normal
Pseudo coincidental data is transmitted. All 256 byte values
occur equivalently. A break is inserted between two packages. This type of test is to simulate the "normal" data
communication in a network.
•
Load
Pseudo coincidental data is transmitted. However, in this
type of test it is transmitted with highest possible transfer
rate.
•
Long
“Stress” data (bit pattern, which lead to a high utilization) is
transmitted at a normal transfer rate.
•
High
“Stress” data is transmitted with high transfer rate.
Attention:
If the looptest is executed in an operating radio net, all values
except normal should be avoided for the parameter LoopMode.
Use of any other value may result in malfunction.
Authorization Level:
Preset value:

2 The WIMAN Command Line Level
LoopTest
MaxRetry
NetId
The parameter LoopTest yields a back loop test. If loop test is
set to True, the WIMAN begins to transmit test data in back
loop operation. Therefore, it is possible to check procedure statistics during the test. This parameter is not available on STAR
devices.
Authorization Level:
Preset value:
False
Scope:
True, False
The parameter MaxRetry determines the maximum number of a
repeated package dispatching. A package is dispatched again
only in the case of a failed checksum test. If a package fails the
checksum test, the WIMAN tries to send the package again. The
number of attempts to resend the package can be determined in
MaxRetry.
Authorization Level:
Preset Value:
Scope:
0 ... 9
The parameter NetId determines the network address of the
WIMAN. The WIMAN analyses only the data communication
that is addressed to the network address configured on it. NetID
also determines which frequency-hopping table is used.
Attention:
Please note that if several WIMAN networks are situated in
close geographical location identical NetIds may not be used.
NodeID
Authorization Level:
Preset value:
255
Scope:
0 ... 255
The parameter NodeId determines the non-standard address of a
WIMAN radio modem within a network. A NodeID with the
value 0 automatically changes the WIMAN radio modem to
MASTER operation. NodeIDs of 1... 250 automatically switch
a WIMAN radio modem into the SLAVE operation with appropriate NodeIDs from 1... 250. Two WIMAN radio modems in
the same network (same NetId) may not possess identical NodeIDs. Disturbance would occur and communication would be
lost until one of the devices is switched off.
This effect does not occur, if a serial number for this NodeID is
set with the instruction peer (see peer below). In this configuration, the WIMAN radio modem with the adjusted serial number

2 The WIMAN Command Line Level
Del Config
Del 
Exit
The command Del Config enables the factory-installed preset
parameter-values to be transferred from the non-volatile configuration to the new configuration. All modifications entered
before will be overwritten. This command can be given in configuration mode only.
The command Del < paraname > enables a transferring of the
factory-installed preset parameter-value for the parameter defined in < parname > from the non-volatile configuration into
the new configuration. All modifications of < parname > are
overwritten with defined parameters. In contrast to the instruction Del Config, it is possible to overwrite directed parameters
with the factory-installed defaults. This instruction can be issued
in the configuration mode only.
The command exit enables you to leave the configuration mode
or the command mode.
When leaving the config mode after having changed at least one
parameter, you will be asked whether these modifications should
be made the present configuration.
You now have the choice to:
•
Make the modifications the present configuration and leave
the config mode by entering ‘y’,
•
Discard the modifications to the present configuration and
leave the config-mode by entering ‘n’, or,
•
stay in configuration mode and make the modifications only
the new configuration by entering ‘c’.
When leaving the command mode after having changed at least
one parameter (at least one parameter was modified in the configuration mode and the modification was made the present configuration), You will also be asked if these modifications are to
be considered with the next restart (They will be transferred into
the non-volatile configuration).
You now have the choice to:
•
transfer the modifications to the non-volatile configuration
and leave the command mode by entering ‘y’,
•
discard all modifications made and leave the command
mode by entering ‘n’ or
•
stay in the command mode and keep the modification of the
parameters exclusively as present configuration by entering
‘c’.
27 / 87l
2 The WIMAN Command Line Level
Note
Entering the command exit at the command line level (Shell)
will always allow you to leave the command mode. This procedure ensures that modifications made in a higher authorization
level are saved.
Export
The command Export makes it possible to export the configuration parameter values into an ACSII-file. The Serial number of
the WIMAN as well as the encrypted passwords are put out, too.
The range of the parameter values depends on the authorization
level in which you are when issuing this command. At the end
of the configuration file, the passwords for the individual
authorization levels are exported in encoded form, excluding the
passwords for the authorization levels you have no access to.
Figure 6 shows a possible configuration file.
Figure 6
exported configuration file


The instruction   enables you to occupy the
defined parameter  with the defined value .
This is the "classic” command for adapting the WIMAN to your
specific requirements. This instruction can be executed in configuration mode only!
Save
The instruction save transfers the present configuration into the
non-volatile configuration. This instruction can be issued only in
the command mode.
Restore
The instruction Restore enables a transferring of the parametervalues from the non-volatile configuration into the new configuration. All modifications completed before are overwritten. This
instruction can be issued in the configuration mode only.
Attention:
Since the parameter-values of the non-volatile configuration do
not have to correspond with the values of the present configuration, an operational disturbance can occur. This can happen due
28 / 87
2 The WIMAN Command Line Level
to a false configuration when leaving the configuration mode
with simultaneous transfer of the data into the present configuration (the query when leaving the config mode was acknowledged with y).
Before storing of the data into the present configuration, be sure
that the parameters are occupied with the values necessary for
your configuration.

3 Configuration of the WIMAN radio modem
Configuration of the WIMAN radio modem
To adjust the WIMAN to your specific network needs it is necessary to modify some of the factory-installed preset parameters.
This modification of the WIMAN can be executed via three different types of interfaces:
•
the wireless interface
•
the RS-232-interface
•
the X.21-interface.
Access to the command line level via the serial RS-232-interface
can take place with the help of a terminal program without previous configuration of the WIMAN. The access to the command
line level via the wireless interface and the X.21-interface requires a previous configuration of the WIMAN.
3.1 Access to the Command Line Level over the
Wireless Interface
To access the command line level over the wireless interface
you have to use a TELNET-Program like NETTERM or the
like. Just enter the correct IP-address of the WIMAN you want
to administer and connect. You will receive the same display as
if connecting via a serial cable.
The big advantage is that you can connect to any WIMAN, no
matter where it is situated, and that you have the same functionality as when connecting directly via cable.
Checklist:
To access the WIMAN radio modem via the wireless-interface
you need:
•
A Terminal program (Telix, Hyperterm, etc.),
•
A PC/Laptop with an online connection
•
A properly configured WIMAN unit
33 / 87l
3 Configuration of the WIMAN radio modem
3.2 Access to the Command Line Level over the RS232 Interface
Checklist:
To access the WIMAN via the serial RS-232-interface you need:
•
Terminal program (e.g. ZOC, TELIX),
•
PC/Laptop with a free serial interface (e.g.. Com1, Com2)
•
Hybrid cable (see chapter 8.3 on page 72)
•
RS-232-connection cable with proper 9- or 25-pin plug/
socket, which fit to the plug/socket of the serial interface of
the PC/Laptop as well as to the RS-232-interface of the hybrid cable.
•
Power supply for the WIMAN (supplied with the WIMAN
hardware)
Follow these steps to access the command line level of the
WIMAN:
1.
Connect the hybrid cable with the 37pin D-Sub connector at
the backside of the WIMAN.
2.
Connect one side of the RS-232 cable with the serial interface of the PC and the other side with the RS-232 link of
the hybrid cable.
3.
Connect the DIN plug of the power supply with the hybrid
cable and the plug of the power supply with an AC socket.
The illuminated power LED on the front of the WIMAN
will indicate that the WIMAN is activated.

3 Configuration of the WIMAN radio modem
The operating system of the WIMAN has an integrated command line interpreter ("Shell") for configuration. Input and output is shown on the input/output window of the PC terminal
program (e.g. TELIX, ZOC), which must be able to emulate a
VT-terminal (DEC). The communication parameters of the terminal program and the WIMAN must correspond so that the
WIMAN and the Computer can communicate.
Note:
The default settings of the RS-232-interface of the WIMAN is
adjusted to a data rate of 9600 Bit/s, a data length of 8 data bits,
one stop bit and no parity check (8N1). As handshaking procedure software handshaking is configured.
To ensure that the terminal program uses the same parameters,
set the communication parameters of the terminal program to the
values stated above. If these parameters were not set correctly
communication with the WIMAN radio modem is not possible.
These values can be preset in the terminal program, thus starting
the terminal program immediately with the suitable settings.
After the WIMAN is attached to the operating voltage, it
switches itself into the transparent data-communication operating mode. Pressing the INPUT key in your terminal program
brings you to the command line level of the WIMAN.
The command line prompt should appear as follows:
WIMAN II Configuration Shell (TTY connection)
WIMAN-II >
If the WIMAN is not configured to the factory-installed defaults, another command line prompt may appear. It is also possible that the first authorization level of the command line level
is protected by a password.
If so, the following message appears:
WIMAN II Configuration Shell (TTY connection)
Enter password:
In this case you need the password of the supplier of the
WIMAN. If the password should not be available, please contact
your WIMAN Distributor.
Note:
If you do not arrive at the command line level of the WIMAN or
if only “confused” characters are shown on the screen after you
have adjusted the above mentioned settings, do not be concerned. It may be that the configuration of the WIMAN has already been modified. In this case test different adjustments regarding the Baud-rate, the Stop-bits, etc.

of sight to the central radio tower. Consider the following:
•
For best results, the antenna on the outdoor housing should
directly face the receiving station (line of sight).
•
Trees, plants, other buildings, walls, etc. can prevent a clear
line of sight.
•
Determine the shortest path for the data cable. The maximum length of the data cable may not exceed 300ft.
•
For installation, choose a discreet place that is not directly
noticeable from the ground. However, aesthetic views are
secondary in respect to a proper operation of the WIMAN.

4.1.7
Second Reception Test
Perform a second reception test to ensure that the selected place
of installation and the selected adjustments offer a sufficient radio reception.
Separate the current supply and the RS232-plug from the Hybrid-2-cable on the WIMAN radio modem.
Further information of the execution of a receipt test can be obtained in chapter 5 on page 55.
After the radio test is completed, reconnect the current supply
and the RS232-plug to the Hybrid-2-cable on the WIMAN.
4.1.8
Installation of the data cable
With some installations, it is possible to use a prefabricated cable of desired length with two 25pin Sub-D plug connectors.
However, this is not possible with most installations. If no prefabricated cable can to be used, it is advisable to attach a plug
connector at one end of the cable prior to installation.
Lay the data cable from the outside inward. Make sure the end
with the 25pin Sub-D connector is outside. It is substantially
simpler to solder the second plug connector on in the internal
area than in the external area.
Be sure that the data cable is sufficiently fixed to the mounting
sets, the mast and to the wall.
Wind up all surplus cables and stow them away. Wind the cable
up in one or two turns. This measure serves as additional lightning protection for the router.

importantly, to test the data link between the Router and the
WIMAN.
You will find details to the reception tests in chapter 6 on
page 58.
To perform the test, connect your Laptop to the RS232-interface
at the Hybrid-cable type 2.
If there is no connection to the WIMAN or if the connection is
unusually slow, follow the instructions specified below to locate
the source of error.
1.
Make sure that the terminal program is adjusted to the correct Baud rate (9600 Bit/s).
2.
The power-LED lights up in green when sufficient operating voltage is supplied, and in orange if the WIMAN performs a looptest. If an internal error occurred the power
LED lights up in red.
3.
Make sure that the RS-232 cable and the power-supply are
correctly connected at both ends of the data cable.
4.
Double-check the solder joints and the pin-allocation inside
the plugs of the data cable.
5.
Check the hybrid cables by alternating them one at a time.
4.1.11 Check the statistics of the X.21-interface

Save all configuration data of the WIMAN radio modems at the radio tower
•
Use the same name conventions used for the cables and
WIMAN radio modems.
•
Record the following information with a terminal program:
Parameter („show“-command)
Statistics („stat“-command)
4.4 Grounding
It is extremely important to ground all installed devices on the
radio tower. This will reduce the amount of damage should
lightning strike. The following steps will also help to reduce
possible damage caused by lightning:
•
Do not mount the WIMAN at the highest point of the radio
tower. This is the point most likely to be struck by lightning.
•
Check that the outdoor housing and the tower standoffs
form a well-grounded metal-on-metal connection with the
tower frame.
•
Avoid using rubber washers or seals.
•
Install lightning protection devices between the data cable
and the hybrid-sets on both the top and bottom of the tower.
•
Ground the data cable to the tower at (a minimum of) three
different places. (1) to the center of the tower, (2) to the
base of the tower where the cable bends (before the bridge
from the tower to the shed) and (3) before the cable runs
into the equipment shed. The best way to do this is to strip
away the outer casing of the cable and affix a grounding
clamp to the cable shielding, then connect this clamp to a
second one which is fixed to the tower.
•
Make sure that all equipment (Switches, Routers, etc.) at the
base of the tower is properly grounded to the rack in which
it is mounted. Also make sure that the rack itself is properly
grounded.

4.5 Burst-Synchronisation
Burst-synchronization is the coordination process of frequency
hopping tables, receipt, and points of transmitting time for several WIMAN networks within the same geographical area.
Burst-synchronization is achieved by both hardware and software items. The hardware item is a synchronization cable, which
is only a wire, which connects the X.21-interfaces among themselves.
For the X.21 Interface, the synchronization cable is enclosed in
the hybrid cable type 3. This is connected to further radio modems with additional cables and special T-connectors.
The software section for synchronization consists of the parameter SyncMode, which is to be entered in the basic configuration of a master or a Slave.
One master radio modem (STAR or LINE) is determined as
synchronization master for all radio modems at that location.
The synchronization master is adjusted as follows:
•
SyncMode = Master
All further master radio modems should be adjusted as follows:
•
SyncMode = Slave
4.6 Extended Point-to-Point Connections
An estendet Point-to-Point connection can be structured by arranging two WIMAN LINE “back-to-back”. For this application, additional hardware is necessary. Please contact your
WIMAN supplier.
For an extended point-to-point connection the parameter
SyncMode has to be set to the base WIMAN LINE configuration.
The example configurations specified below refer to an extended X.21 Point-to-Point-connection. In this structure, the
WIMAN LINE Slave 1 is coupled to the WIMAN LINE Master

5 Reception quality and transmission speeds
For the examination of the receipt quality as well as to error detection, test loops can be generated. The type of test loop can be
influenced by the configuration of the parameters LoopData,
LoopMode and LoopTest.
The parameter LoopData enables the setting of the Byte-values
that are to be generated (see page 18). This parameter can be
produced on a WIMAN ACCESS only.
The parameter LoopTest enables a switching to a test loop, with
which the data, which can be transmitted, is produced independently by the WIMAN radio modem (see page 19).
This test loop can already be activated in the lowest authorization level and is, in combination with the statistics analysis on
the wireless interface, an outstanding inspection procedure for
radio communication.
The parameter LoopMode determines, which bit pattern will be
transferred with the back loop in the loop test operation from the
WIMAN radio modem (see page 18)
Attention:
If the back loop test is execute in an operating radio net, avoid
all values except normal. Use of any other value may result in
loss of performance.
5.1 Configuration of a TestLoop with Independently
Generated Data Communication
1.
Access the command line level of authorization level one
(see chapter 2 on page 13) and change into the configuration mode. You will see an output similar to:
WIMAN-II (config) >
2.
Type in the command looptest true.
3.
Check with show looptest the value for the parameter
Looptest. This should now be switched to true. The following output appears:
WIMAN-II (config) > show looptest

/ (n)o / (c)ancel ?
You now have the choice:
To transfer the new configuration into the current configuration and to leave the configuration mode by
pressing the key „y“,
To discard the modification but to leave the configuration mode anyway by pressing the key „n“ or
To not take over the modification into the current configuration but to stay in configuration mode by pressing the key „c“.
Press the „y“ key to activate the looptest. The modification
of the parameter becomes part of the current configuration
and the WIMAN starts transmitting bit samples.
5.2
Test after a Radio Tower Installation with Synchronisation
After all devices are correctly installed, a final test must be executed. This final test checks if all devices are installed correctly
and whether a trouble free transmitting and receiving mode is
possible.
•
Switch on the first WIMAN radio modem. Always begin
with the WIMAN determined as synchronization master.
•

6.1 Technical Description of the Frame of Relay Features
The WIMAN STAR supports the multiplexing of Frame Relay
packages. In multiplexing procedure, the packages received
from the Frame Relay Switches are transferred to the WIMAN
ACCESS, which is connected to a Frame Relay Router at the
user’s site.
Figure 10
Frame Relay connections with the WIMAN
For addressing the WIMAN ACCESS the DLCI number (Data
Link Connection Identifier) of the Frame of Relay protocol is
used.
The following restrictions apply to the Frame Relay support:
•
Only static connections are supported (PVC = Permanent
Virtual Connection)
•
DLCI numbers must be configured statically on the Frame
Relay Switch and the Frame Relay Router
•
2-, 3- or 4- Byte-Frame Relay-address-arrays are supported,
•
Since the WIMAN node address is embedded in the DLCI
number (10-bit DLCI with implemented WIMAN node
identifier), the DLCI allocation of numbers is reduced
•
Up to four virtual connections are supported for each Frame
Relay user
•
Up to 250 Frame Relay users are supported at a WIMAN
STAR (currently 9 users possible, Software Version T0.7).
•
The following Frame of Relay features are not supported:

7 Troubleshooting
Troubleshooting
7.1 Techniques and Methodologies Used for Troubleshooting
7.1.1
General Problems
This section lists some common problems that may occur and
cause a malfunction in the WIMAN system:
Bad RF-Link between STAR (Master) and ACCESS (Slave):
•
STAR units are not synchronized ! see stat sync
•
Bad hardware on the STAR or the ACCESS
Check RF statistics from the STAR to other ACCESS devices ! see stat wl ext
If all other connections are functioning properly,
STAR is not defective.
•
If the star is working correctly consider the following questions:
Is the ACCESS device configured correctly (correct STAR,
correct sector)?
Are there any obstacles between the STAR and the
ACCESS?
Is the antenna cable attached correctly?
Is the antenna adjustment correctly?
Is the ACCESS device itself defective (defective transmitting or receiving part)? ! If so, exchange the device.
Are two ACCESS devices within a network configured with
the same NodeID? Check the ACCESS configuration, the
network configuration and the documentation of the other
ACCESS radio modems within in the same network.
No data communication from the STAR to the ACCESS:
•
Check the radio connection between the ACCESS and the
STAR.
•
Check the wiring of the STAR and ACCESS
Check the other radio modems attached to this STAR
If data can be transmitted to the other ACCESS devices then the wiring at the STAR is OK.
66 / 87
7 Troubleshooting
If you are still uncertain whether there is a problem
with the wiring of the STAR, proceed as follows:
Check the statistics with the commands stat serial ext
and stat wl. If you transmit a Ping, the
Rx and Tx-counter should be increased.
Check whether the data cable is wired according to the
specifications shown in chapter 10, page 82.
Check all modules for correct wiring.
Check the hybrid cables.
Check the interface converters.
Check the cross over cables.
Check the wiring on the ACCESS:
Check the statistics with the commands stat serial ext
(see page 49) at the ACCESS-side. If you transmit
a Ping, the Rx and Tx-counters should increase.
Check whether the data cable is wired according to the
specifications shown in chapter 10 on page 82.
Check the wiring of all modules.
Check the hybrid cables.
Check the routing tables.
•
With the instruction stat hw compare the serial number entered in the device table (peer-table) with the actual serial
number of the device. If the serial number does not match,
all data packages will be discarded. Enter the following to
delete an existing entry in the device table:
PEER  
Afterwards reset the device.
•
Check whether the looptest at the ACCESS radio modem is
still active (show looptest). The Parameter „LoopTest“ must
be set to „false“.
•
Defective Router at the customer side:
Check the configuration
Check the Hardware
•
PVC
PVC was built on the wrong port
PVC was built with wrong DLCI (according to the appropriate NodeID of the ACCESS)
•
Routing tables
67 / 87l
7 Troubleshooting
•
Bad port on the switch
Check other customers who are attached to the same STAR
In case no further customers are attached to the same
STAR, try attaching the device to another port.
WIMAN Baud rate parameters are not adjusted correctly:
If the WIMAN radio modem does not interface with the terminal program, the Baud rate may be set incorrectly on the
WIMAN and/or the terminal program.
Frequency table adjusted incorrectly
If the WIMAN Slave cannot construct synchronized connections
and you are using generated frequency tables, check that the parameter "FtabMode" is adjusted to "user". Make sure that all
parameters are configured correctly.
Parameter destination not adjusted correctly (LINE only)
This situation cannot occur after a loop test. If the Socket program cannot structure a connection, check the network and ensure that all parameters "destination" are set to the correct value.
Baud rate in the Socket program not set correctly
If the Socket program cannot construct a connection, it could be
that the Baud rate is set incorrectly on the Socket program
and/or the WIMAN.
Parameter NodeID not set correctly
If an ACCESS radio modem receives synchronization impulses,
but no data can be transmitted, it could be that the parameter
NodeID is adjusted incorrectly. The double assignment of a
node number in the same network leads to malfunctioning.
Serial number does not correspond with the device table
(Peertable)
If the WIMAN STAR is adjusted to a serial number that differs
from the one used in the Peertable, malfunction may occur.
IP-Parameter in the Socket-program not set properly
If the Socket program over the ACCESS radio modem cannot
construct a connection, check whether all IP parameters are adjusted correctly.
Damaged or defective antenna cable
Damaged or defective synchronization cable
68 / 87
7 Troubleshooting
Any of these problems may lead to poor or no radio communication. Check the antenna cables for damages. If there are no
damages, check the synchronization connection. If the problem
persists, the WIMAN may need to be replaced.
7.1.2
Troubleshooting with Radio Tower Installations
•
If the WIMAN radio modem can not be accessed over the
RS-232-interface, the problem may be caused by:
A non-corresponding Baud rate of the terminal program and
the WIMAN (usually the Baud rate is adjusted to 9600
Baud)
Incorrectly attached cables
Faulty Hybrid-2 or Hybrid-3-cables. Exchange the Hybrid2-cable first and then the Hybrid-3-cable (if necessary).
Faulty contacts inside the data cable plug. Check the configuration and transmission with an extra 25pin data cable.
•
In case the ACCESS can get no RF-synchronization signal
(indicated by the Status-LED at the front side of the unit) or
if the synchronization signal reception is periodically interrupted, the problem may be caused by:
Incorrect configuration of the ACCESS or STAR. Check
whether all parameters are correct.
The operating voltage at the star radio modem is too low. If
the operating voltage at the WIMAN radio modem drops
below the given threshold value, a restart is performed
automatically. It is advisable to constantly apply a voltage at the radio modem by at least 12V.
Defective or unattached antenna cable,
A Faulty Hybrid-2 or Hybrid-3-cable. Replace the Hybrid2-cable first and then the Hybrid-3-cable (if necessary).
Defective RF filters.
Defective WIMAN STAR or ACCESS.
Faulty contacts inside the data cable plug. Check for perfect
configuration and transmission with an additional 25pin
data cable.
Defective synchronization cable (short-circuit in the plug)
of and to the testing device.
Defective T-connector (short-circuit)
