Chapter 4: Getting Started

Getting started

To get started, follow the steps below:

Step Action

1 Install the management application (IDR-C MASTER) in the Local Craft Terminal (page 9).

2 Install the manufacturer driver in the Local Craft Terminal and create a dial-up connection between the Local Craft Terminal and the IDR-C of the station (page 9).

NOTE

Through the creation of the dial-up connection, the IDR-C assigns the LCT an IP address equal to the IDR-C station IP address + 1 (e.g. if the IDR-C station IP address is the 192.168.59.37, the LCT IP address will be the 192.168.59.38).

3 Connect the Local Craft Terminal to the IDR-C of the station (page 16).

4 Change the IP address of the station (page 102, Annex B: Changing the Station Name, the Link Name and the Station IP Address).

5 Repeat steps 2, 3 and 4 for all the IDR-C stations. 6 Launch the IDR-C MASTER (page 17). 7 Get connected to the IDR-C you want to configure (page

19). 8 Set the IDR-C clock (page 22). 9 Proceed to the configuration of the IDR-C (page 23).

Special case: IDR-C connected to a router

You can connect the NMS1 or NMS2 port of the IDR-C to an asynchronous serial interface of a router but you should configure the router serial interface baud rate fixed at 57600 bit/s and assign the router interface an IP address in the same subnet as the IDR-C which is not used in the IDR-C network. Example: If the IP address of the IDR-C is 192.168.59.5, assign the IP address 192.168.59.253 to the router serial interface (if you assign the IP address 192.168.59.6 to the router interface, the RIP will be deactivated for this port as the IDR-C considers it is an LCT and not a router port thus deactivating RIP transmissions). Find an example of a router configuration on page 108, Annex C: Example of Router Configuration.

NOTE

The only route the router needs to advertise towards the IDR-C stations is the default route. Please note that each station routing table can store up to 10 station routes (IDR-C stations) and one default route.

Optimizing the Link

Info To achieve reliable transmission in a microwave link, the transmitted

power plus the gain of the transmitter and receiver antennas should exceed the attenuation at the transmission path and the sensitivity of the receiver. The attenuation at the transmission path is given in the following formula:

A=92.4+20logD+20logF A is the attenuation at the transmission path in dB D is the distance between the antennas in km F is the frequency of the microwave signal in GHz

Prerequisites If you use the LCT to observe the reception level or the RSSI, you will

need another person to move the antenna.

Procedure To optimize the link, while performing minor horizontal and vertical

movements of the antenna, do one of the following: • Open the ODU tabbed sheet and check the reception level in the Rx

In box in the Radio Measurements group box:

• Open the IDR View tabbed sheet and check the reception level in

the Rx In box in the appropriate ODU Home group box:

Annex B: Changing the Station Name, the Link Name and the Station IP Address

IDR-C IP Addressing

Each station with an IDR-C system is assigned an IP address so that it

can be identified in a network. The IP address of each station has to be unique in the network to which the station belongs. You can use the LCT, type the appropriate IP addresses and get connected, monitor and configure up to 10 stations. All stations should belong to the same subnet with subnet mask 255.255.255.0 As four IP addresses should be reserved for each station (the IDR-C station address, the broadcast address, the network address and the LCT address assigned to the LCT through the creation of the dial-up connection between the LCT and the IDR-C), the IP address of the station should have the following format: A.B.C.D/30 with D=4n+1 where n is an integer from 1 to 62. See below an example of IP addressing:

Station IP Address Station 1 192.168.59.5 Station 2 192.168.59.9 Station 3 192.168.59.13 Station 4 192.168.59.17

… … Station 10 192.168.59.41


103

Finding out the IP Address of your Station

Prerequisite Before proceeding to the procedure, you should create a dial-up

connection between your LCT and the IDR-C.

Procedure To find the IP address of your station, follow the steps below:

Step Action 1 Double-click on the icon of the dial-up connection that you

created for the communication of your LCT with the IDR-C. 2 Select Start>Run. 3 In the Open box, type command (Windows 2000 or XP). In

the DOS prompt, type ipconfig.

You view the IP address of your LCT.

4 To find the IP address of the station, reduce the IP address of your LCT by one. In the example, the IP address of the station is 192.168.59.37


104

Changing the Station Name, the Link Name and the IP Address of your Station

Info The name of the link and the name and IP address of the station are

stored in the config.sys file that is kept in the CMS card of each station. The IP address of the station is also stored in the boot.sys file of the system. If you want to change the IP address of a station, you should change the contents of the boot.sys and config.sys files accordingly. If you want to change the link name and the station name, you should change the contents of the config.sys file.

Prerequisite Before proceeding to the procedure, you should create a dial-up

connection between your LCT and the IDR-C.

Procedure To change the link name and the name and IP address of a station,

follow the steps below:

Step Action 1 Upload the config.sys and boot.sys files from the IDR-C to

your LCT. 2 With a text editor open the files and change the name of the

link and the name and IP address of the station. 3 Delete the old config.sys and boot.sys files from the IDR-C. 4 Download the modified files from your LCT to the IDR-C. 5 Reset the IDR-C.

Find the detailed description of the preceding steps in the following paragraphs.

10 Type exit, and then press ENTER to return to Windows.



106


Editing the config.sys and boot.sys files

To edit the config.sys and boot.sys files, follow the steps below:

Step Action

1 With a text editor open the config.sys and boot.sys files. The file format will be similar to the one below (depending of course on the frequency and the type of the station): • The config.sys file boot id180203.bin 0xa000400 MANAGER_IPADDRESS 146.124.12.75 MANAGER_PORT 16205 MY_IPADDRESS 192.168.50.31 SUBNET_MASK 255.255.255.252 lnkname LowSyst The station name sysname Intracom The Link name systype 1 1+1 • The boot.sys file boot id180203.bin 0xa000400 MANAGER_IPADDRESS 146.124.12.75 MANAGER_PORT 16205 MY_IPADDRESS 192.168.50.31 SUBNET_MASK 255.255.255.252

2 In both files, replace the IP address next to the MY_IPADDRESS record with the new one. Note: If you want, you can also change the name of the station that appears on the display of the CMS and the name of the link. To do so, in the sixth line of the config.sys file, change the name of the station from the LowSyst of the example to the one you want to appear on the display of the CMS. In the seventh line of the config.sys file, change the name of the link from Intracom of the example to the one you want.

3 Save the config.sys and boot.sys files and close the text editor.
