The first reflex is to assign the MCCH to BS n° 2 using one of several methods: -Deactivate BS N°1 : Then wait for the synopsis to be refreshed Activate BS N°1 Two possible cases: => The number of registrations is no longer nil, showing that BS 1 has a fault => If the number of registrations is still nil: Check the antenna system (coupling + antennas) Check the receiver chain (Preamplifier distributor, DCTR) The configuration parameters for the base stations may be incorrect (frequencies, network code, ac
-Switch BS N° 1 off and on again: Same as the previous case for analysis and results -Reboot the BS N° 1 CPU board: Same as the previous case for analysis and results 4.5 Mobiles register correctly to the network but are unable to communicate The base stations reply normally to a 'zoom' request from the service network management terminal NeTIS MAINTENANCE GUIDE – Version 1.

NeTIS-B & NeTIS-N software A compact Flash board plays the role of the hard drive and equips the CPUBDT and SUPIP boards The installed operating system is DEBIAN LINUX. 5.1 NeTIS-B 5.1.1 GENERAL The 'Niveau2.exe" software is the ETELM application operating in a NeTIS-B. As for all computers, the board boots the operating system and loads niveau2. Total load time: ~40s 5.1.2 LAUNCHING THE « NIVEAU 2.

6. PUTTY (remote connection) This “SSH” client can be used to obtain a secure connection from Windows to Linux servers. It can be used to change the Network settings of the remote board, stop software, start software, reboot the PC, and remotely run software. NeTIS MAINTENANCE GUIDE – Version 1.
Launch putty.exe: The factory setting for the Network board is 192.168.1.3, however, if this has been changed, use the new one. Then type “Open” If a security message appears, press on “Yes” NeTIS MAINTENANCE GUIDE – Version 1.

7. WINSCP – SOFTWARE UPDATE *See also the "Authentication" chapter which only covers NeTIS-Bs. Use the "WINSCP3" software. This software is used for the secure transfer of files (version 2 of the SSH protocol) between a Windows station and a Linux server. It is used to update the versions of BS, SWITCH end LINUX SUPIP. Connection via Ethernet link and CPUBDT board. The factory setting for the Network board is 192.168.1.

Click on the usr directory NeTIS MAINTENANCE GUIDE – Version 1.
Next choose the directory that corresponds to the board's current operation: If you are connected to a BS CPU board, select the BsLinux directory. If you are connected to a SWITCH SUP board, select the SupipLinux directory. NeTIS MAINTENANCE GUIDE – Version 1.
If you are connected to a SWITCH SUP board, select the SupipLinux directory. Next it is possible to run all the classical Windows Explorer commands Rename, delete ... using a right mouse click on the file to be modified. 7.1.1.1 Example of the update of a Bs Linux version: Navigate to the directory usr/BsLinux as shown above: Right mouse click the niveau2 file, the scroll down to rename: Change the file name to niveau2v611 for example, if the BS version is a 6.
To activate this version you must either turn off the BS (Front Face Reset for example), or using a software method using the putty software that we will examine in the second part of this document. NeTIS MAINTENANCE GUIDE – Version 1.
8. NETWORKS The objective of this chapter is to describe the configuration of the links between NeTIS equipment as well as fault diagnosis. There can be 3 types of link: G703 Ethernet V11 A network can have a single type of link or several different types. 8.1 « Stars » network NeTIS MAINTENANCE GUIDE – Version 1.
