2. LAN / Ethernet network

2.1 General principle

Each BMS (centralized technical management), BMS/energy, signaling and ticketing application, generated or originating from the servers, switches and hubs located at the PCC (respectively at the Elsau depot), requires a LAN/Ethernet network which, depending on the needs expressed, must be present in all stations.

The various types of service required to operate Line B are as follows:

• an IP-type Ethernet segment for BMS/energy ;

• an IP-type Ethernet segment for the GTC suite link ;

• an Ethernet II (Ethway) segment for signaling ;

• an Ethernet II (Ethway) segment for the BMS ;

• ...
