8.1.1.2 IT configuration on the Switch We will use the network management terminal to identify the link it number to the SWITCH as well as the position in the SWITCH rack of COM3 in charge of the link: Position 1 to 12 for a standard chassis. In CONFIGURATION / SETTINGS. Right click on a BS then select Name Tc/Ts. The window below appears. The G703 link configuration has a red border: Junction: Link type Voice/@IP: corresponds to the link it number Board: corresponds to the location of the COM3/4 board in the SWITCH (Counting from the SUPIP) The Tx=Rx check box means that the dialogue it is identical for both sides of the link. For the In and Out settings and the preferred direction refer to paragraph 9.1.2 Ring Network The In and Out list zones must be filled in as in the window: Ins: for the link the SWITCH 0/1 SW precedes the BS for consultation Outs: for the link, no equipment succeeds the BS for consultation Fault analyses and diagnosis NeTIS MAINTENANCE GUIDE – Version 1.1 71/139 8.2 « Ring » network NeTIS MAINTENANCE GUIDE – Version 1.1 72/139 8.2.1 OPERATING PRINCIPLES Link type: always G703 Type of module in charge of the link: COM 3/4 Normal operations: (see §9.1.2.2) Each NeTIS-N appliance transmits data to the NeTIS-Bs on an it in both directions of the loop and extracts data from the NeTIS-Bs only from one direction at a time Each NeTIS-B appliance transmits data to the NeTIS-Ns on an it in both directions of the loop and extracts data from the NeTIS-Ns only from one direction at a time depending on the preferred direction selected in the settings More precisely, the COM3 or COM4 board plays the role of G703 interface on the BS side and the SWITCH side, it permanently transmits on both G703 junctions; The signal received at these junctions are analysed and the indicators on the front face make it possible to know the state of these junctions: 'ERR’ indicator: red indicator lighting when a line error is detected on the junction or if there is no 2Mb/s signal (disconnection for example). Yellow 'Rx’ indicator: flashes when a G704 synchronisation is detected; stays on when a synchronisation is detected and the link with the switch is established.

Various applications (Recorder, phone gateways, etc ...) NeTIS MAINTENANCE GUIDE – Version 1.1 85/139 B IP IP SWITCH IP SWITCH SWITCH PABX PSTN Others applicatif IP All the elements of the radio network are linked together through an IP network. The radio network clients (BS, Operator station, etc ...) have a minimum configuration, adding an element must not cause the reconfiguration of existing elements. NeTIS MAINTENANCE GUIDE – Version 1.1 86/139 8.3.2 COMMUNICATIONS BETWEEN APPLIANCES NeTIS MAINTENANCE GUIDE – Version 1.1 87/139 NeTIS MAINTENANCE GUIDE – Version 1.1 88/139 8.3.3 CUSTOMERS 8.3.3.1 Phone applications These applications need to use signalling and phone. (Operator stations, Phone gateways, etc.). Operator station Customer UDP Identification Customer UDP Signalisation TCP Customer to highest priority SWITCH UDP reception UDP reception Reception of all switches present on the network and management of a dynamic switch table. Switch signalling channel reception with the highest priority for communications management. Link with the highest priority switch for communications management, it is the "active" link. TCP/IP links Phone UDP customer UDP broadcast TCP customer to lower priority switch TCP/IP links Reception of transmission from the PHONE channel Link with the lowest priority switch and connection with the highest priority switch that arrives on the network. IP NeTIS MAINTENANCE GUIDE – Version 1.1 89/139 8.3.4 NETWORK SETTING 8.3.4.1 Role of the UDP Identification Server Each switch broadcasts an identification message on a UDP channel permanently (every 5 seconds). The UDP port number used for this broadcast is therefore part of the minimum information needed in the Clients (NeTIS-B, Operator Station etc...) wanting to connect to the radio network. This message makes it possible for the BSs to send information about themselves to the servers (NeTIS-N): CPU IP addresses, Switch N°, SUP IP addresses Then the SWITCHES send the following information to the clients: IP address and Port of the BS signalling server (see §9.3.4.4) IP address and Port of the BS Phone server (see §9.3.4.4) The port used to broadcast this message and the broadcasting address are set via the network management terminal and transmitted to the NeTIS-N by downloading. A file in the NeTIS-B is used to declare the identification port used by the NeTIS-N(s). 8.3.4.2 UDP identification server configuration The UDP identification server is in fact the NeTIS-N The server is configured from the network management terminal as shown below In NeTIS MAINTENANCE GUIDE – Version 1.1 90/139 Select « IGMP » tab The broadcast of server information (NeTIS-N) to the clients (NeTIS-B) is carried out using a Broadcast address and is defined as shown below Select the "Configuration" tab NeTIS MAINTENANCE GUIDE – Version 1.1 91/139 8.3.4.3 Port identification declaration on the NeTIS-B side A base station that wants to connect to the tetra network listens on its identification port in order to obtain the information from the different SWITCHES on the network with their priority level. To declare this port, a configuration file (Text) stored on the NeTIS-B must be read the path of which is /USR/BsLinux/nano CONFIGBS.CFG. Below the content of the CONFIGBS.CFG file shows that the identification port is "51114" "Top of file ######### IP PARAMETERS Commands to close the file for example: CTRL X(^ X) IDENTIFICATION PORT N° PORT_IDENTIFICATION = 51114 [ Read 62 lines ] ^G Get Help ^O WriteOut ^R Read File ^Y Prev Page ^K Cut Text ^C Cur Pos ^X Exit ^J Justify ^W Where Is ^V Next Page ^U UnCut Txt ^T To Spell "End of file 8.3.4.4 IP Network without using the identification port If the port is not filled in in the BS, then port "51114" is used as a default.

Port configuration on the network management terminal side: In NeTIS MAINTENANCE GUIDE – Version 1.1 94/139 8.3.5 DECLARATION OF THE NETIS-B ADDRESSES ON THE TETRA CS SIDE The SWITCH has a view of all the BSs that are part of the network via their IP address configured as shown below. When a configuration request for a BS is received, the SWITCH can load its configuration using the BS IP address. This address is also used to route phone and network communications. In NeTIS MAINTENANCE GUIDE – Version 1.1 95/139 IP-TCP: All Signalling and Phone exchanges use TCP/IP IP-UDP: All Signalling exchanges use TCP/IP All the Phone exchanges use UDP/IP NeTIS MAINTENANCE GUIDE – Version 1.1 96/139 8.3.6 SWITCH SIGNALLING AND PHONE PORT These SWITCH CPU ports and addresses will be used by the DISPATCHING. The Operator Stations must know the CPU IP (Signalling) address and the associated Signalling Port. As well as the phone port used by the SUPIP board. The SUPIP IP address is not used by the operator stations because phone is broadcast directly onto the IP network (UDP protocol) whereas for signalling both the TCP and UDP protocols are used. The SWITCH is configured by a download from the equipment database from the network management terminal. 8.3.7 SECONDARY NETWORK MANAGEMENT TERMINAL 8.3.7.1 General A network always has a primary network management terminal connected using an RS232 link to the NeTIS-N. You can add secondary network management terminal connected using IP to the main network management terminal . The rights of the secondary network management terminal are limited to network monitoring and to the ticket history (Logging) and you cannot load configurations to the NeTIS-N from it. NeTIS MAINTENANCE GUIDE – Version 1.1 97/139 NeTIS MAINTENANCE GUIDE – Version 1.1 98/139 8.3.7.2 Secondary network management terminal installation Retrieve the TetraCs directory from the primary network management terminal and paste it under the C: root of the new PC. Create an application short cut and in the "Target" field of the tetraCs properties add the word "secondary" as shown below: NeTIS MAINTENANCE GUIDE – Version 1.1 99/139 Launch the application 8.3.7.3 Configuring the main network management terminal The main console is considered to be a server to which the secondary network management terminal will connect. To do this, just declare a port for exchanges between consoles. The server listens on the port defined below. NeTIS MAINTENANCE GUIDE – Version 1.1 100/139
