The GSM-R gateway is a separate device mediating communication between the GSM-R network and the integrated communication system Radiovoice 3 at the level of connection to the network infrastructure of the GSM-R system. The GSM-R gateway in conjunction with the TOP telecommunication control panel provides voice communication between control and railway staff (dispatchers, dispatchers) and end users working in the GSM-R network (drivers, train staff, maintenance staff, etc.). Voice communication fully complies with the functional and system requirements of the European Integrated Railway Radio Enhanced Network (EIRENE) specifications.
Advantages of using a GSM-R gateway
- Gateway for connecting the integrated dispatching system Radiovoice 3 to the GSM-R network
- Fully complies with EIRENE specifications
- Possibility of 230 V or 48 V power supply
Basic technical description
The GSM-R gateway is built into a cabinet designed for mounting in a 19 “rack, 1.5 U high and 30 cm deep (without connectors), the gate weighs 3 kg. The gate can be powered from 230 V, 50 Hz or 48 V DC. Gate cooling is active – fans.
GSM-R gateway functions
The GSM-R gateway provides two-way conversion of voice calls between the TCP / IP data network environment with SIP (Voice over IP) protocol on the side of the integrated dispatching system Radiovoice 3 and the ISDN voice network environment (PRI interface) on the GSM-R network side. The GSM-R gateway allows up to 30 simultaneous calls to the GSM-R network, including recording of all through traffic.
The expected use of the GSM-R gateway depends on the number of control rooms and their number corresponds to the implemented integrated line sections. The connection between the GSM-R gateway and the TOP telecommunication control panel of the integrated radiovoice system 3 already takes place via the Ethernet network. The principle of decentralized deployment of GSM-R gateways reduces the requirements for their power capacity, enables the division of operational load and thus increases the resilience against outages and failures.
