SYSTEM DESIGN & INTEGRATION

Radio equipment and transport networks,
designed as one system.

DCS is a communication system that carries train control data between onboard and trackside equipment. We define the integration requirements for radio links, wired backbones and network management together.

Radio Links
Radio environment surveys, cell analysis and planning, and coverage testing for routes, stations, tunnels and depots
Data Relay
Connect upper and lower networks through data communication equipment in control centers and communications rooms, and manage communication paths and devices
Transport Network Configuration
Optical and Ethernet backbones, L2/L3 switches, IP routing and multicast (PIM·IGMP) integration
Onboard–Trackside Integration
Train interfaces, radio equipment and antenna configuration, data transmission and reception, and communication quality during movement

RAIL COMMUNICATION SOLUTIONS

Data, voice and video,
communications for railway operations, together.

Building on DCS, we design connections between railway communication networks and control, passenger information and safety equipment.

Main Transport Network & Network Management

We design and build optical and IP transport networks and manage equipment interfaces and network testing. EMS and NMS provide device status and fault monitoring.

Optical & IP Transport · Interfaces · EMS/NMS

Railway Radio Integration

We provide network design, coverage verification and terminal-to-control-center integration for LTE-R sections. We work with core communications equipment suppliers to meet field operating conditions.

Network Design · Coverage Verification · Terminal & Control Center Integration

Control Center Telephony & Emergency Calls

We configure control center telephony and platform emergency call equipment and integrate them with IP-PBX and communication networks. We verify call routing, call functions and fault status together.

Control Center Telephony · Emergency Calls · IP-PBX Integration

Passenger & Safety Equipment Integration

With specialist suppliers, we coordinate installation, testing and interfaces so CCTV, destination displays, passenger announcements and access control equipment operate on shared transport networks and within the control environment.

RAIL COMMUNICATION ENGINEERING

From design documents to field testing,
connecting every stage of communications delivery.

Radio Surveys & Communications Design

We survey route environments and installation conditions, then design radio cells, frequencies, antennas and transport networks.

Field Surveys · Cell Analysis & Planning · Interface Definition

Installation & System Integration

We coordinate communications equipment, cabling and network settings across onboard, trackside, control center and depot systems, and verify installation status.
