3 Configuration of the WIMAN radio modem

Information:

The following instructions can be issued likewise from all

higher authorization levels.

2. Change from the command mode of the authorization level

one (indicated by the character " > " at the end of the com-

mand line prompt) into configuration mode by entering the

command config.

The command prompt of the configuration-mode appears:

WIMAN-II (config) >

3. Type in the command passwd console and press ENTER.

You are now asked to type in a password:

Enter password:

4. Type in the new password.

Note:

Keep in mind that the password is case-sensitive

If a password is already set it will be overwritten.

Each entered character is shown as a „*“ on the screen.

The new password is saved in the new configuration and is

not yet active.

5. Type in exit and leave the configuration mode (see

page 27).

6. Proceed as shown in chapter 3.4.1 on page 36.

3.5.2 To delete a Password for the Authorization Level

one

To delete a password for authorization level one:

1. Access the command line prompt of the authorization level

one.

The display will show the following:

Enter password: ****

Type in the required password. Remember that passwords

are case-sensitive.

The command-line prompt appears, for example:

Configuration of the WIMAN radio modem When accessing the command line prompt of authorization level one the following prompt will appear:: Enter password: **** Enter the password for the authorization level two (pay attention to upper- and lowercase characters). The command line prompt should appear, e.g.: WIMAN-II # 2. Change from the command mode of authorization level two (indicated by the „#“- sign at the end of the command line prompt) into the configuration-mode by entering the command config.

Hardware Installation 4 Hardware Installation 4.1 Installation instructions for the WIMAN Accessradio modem The following sections deal with the installation of a WIMAN ACCESS radio modem on a single PC containing the operating system Windows. Linking to a LAN requires an experienced network administrator. The method of installation depends strongly on the type of LAN 4.1.
PAGE 5
4 Hardware Installation Note: There is no power switch on the WIMAN. The connection is successful when the operational status indicator on the front side of the WIMAN lights up green. 5. Connect the RS-232-interface to the computer interface. If you use the serial interface of a PC or Notebook, please refer to the configuration specified in Chapter 3 on page 33. As soon as it is attached to the power supply, the WIMAN ACCESS begins to boot and starts to search for the proper WIMAN STAR.

4 Hardware Installation • 4.1.5 Be sure to discuss the details of installation with the customer in respect to the local construction and homeowner regulations. First Reception Test This first reception test serves to determine if the optimum field strength can be obtained from the installation place and adjustment of the WIMAN outdoor sets. Further information about reception tests can be found in chapter 5 on page 55. 4.1.
PAGE 8
4 Hardware Installation - Use the j-shaped wall mount if you are installing the WIMAN on the side of the building directly facing the radio tower. Use the aluminum mast mounting kit if you are installing the WIMAN not facing the radio tower directly due to an obstacle (e.g. rear side of a wall etc.). Use the tile roof mounting set if you are installing the WIMAN to a roof with roofing tiles. 4.1.

4 Hardware Installation 4.1.10 Final reception test with installed data cable The final reception test is necessary for two reasons: First to examine the assembly position of the WIMAN, second, and more 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.

4 Hardware Installation 2. Double-check the solder joints and the pin-allocation inside the plugs of the data cable. 3. Check the hybrid cables by alternating them one at a time. 4.2 Installation of a WIMAN Star 4.2.1 Additional necessary components Checklist: In addition to the parts specified in Chapter 4.1.2, page 45, the following components are needed for the installation of a WIMAN STAR: 4.2.

4 Hardware Installation - All data cables (upper and lower end) - All small external housings (if used) - All antennas on large external housings (if used) - the radio modem designated as synchronization masters, with the additional designation "Sync master", 4.3 Installation at the Radio Tower 4.3.1 Installing the tower standoff at the radio mast 4.3.

4 Hardware Installation 4.3.7 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.

4 Hardware Installation 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.

5 Reception quality and transmission speeds 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.

6 Frame Relay 6 Frame Relay 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.
