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.

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.
In the case of correct reception on both sides (A and B), the COM board only keeps the signals received from the side declared as preferred (settings on the network management terminal). The board injects signals corresponding to the TBS11 in the assigned time slot (programming on the rear face of the NeTIS-B see §9.1.1.1) on both junctions A and B at the same time and transparently retransmits the other time slots, in both directions from one junction to the next and vice versa. 8.2.
8.2.2.2 NeTIS-B configuration Each NeTIS-B on the network must be configured to work on an it from the G703 link (see §9.1.1.1) 8.2.2.

Switch signalling channel reception with the highest priority for communications management.
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.
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.
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.

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.

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.
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.

To do this, just declare a port for exchanges between consoles. The server listens on the port defined below. NeTIS MAINTENANCE GUIDE – Version 1.
