SIP Audio & Video Communication Solution for Sydney Metro City & Southwest, Australia
Sydney Metro City & Southwest is a landmark smart rail transit project in Australia. With a construction period from 2020 to 2024 and a total length of approximately 30 km, the project consists of a newly built metro tunnel section and an upgraded existing railway section. The new section was officially opened in August 2024, recording more than 66.8 million passenger trips in its first year with a passenger satisfaction rate of 98%.
The project is equipped with an AVAYA dispatch system. However, challenging operating environments, including high humidity and dust in tunnels as well as potential equipment damage in public areas, created higher requirements for communication terminal reliability and adaptability. Customized SIP communication terminals were therefore required to ensure stable and efficient communication across different application scenarios.
Customized SIP Communication Solution
J&R delivered SIP audio and video communication terminals for this project, covering tunnels, trackside areas, platforms, and passenger service areas. All terminals support SIP protocol and seamlessly integrate with the AVAYA management platform. The solution includes both audio and video communication terminals, deployed according to different application requirements to support railway operators, station staff, and passengers.
· JR101-FK-SIP Industrial Audio Telephone
Featuring high-level waterproof and dustproof protection with built-in noise reduction technology, the terminal is designed for noisy and humid environments such as tunnels and trackside areas, ensuring clear and reliable communication for maintenance personnel.
· JR101-CB Audio Hotline Telephone
Designed with an industrial-grade structure and one-button auto dialing function, the terminal provides reliable communication support for trackside areas and other operational locations.
· JR213-V-2B Visual Emergency Call Terminal
Integrating high-definition video communication and one-button calling, the terminal enables passengers to establish visual communication with the control center, allowing rapid response to passenger assistance requests.
· JR301-SC-C-IW-SIP Embedded Video Intercom & JR301-SC-C-OW-SIP Wall-Mounted Video Intercom
Featuring a stainless steel vandal-resistant housing and IP65 waterproof protection, the terminals are available in embedded and wall-mounted versions to meet different station installation requirements. They support two-way HD audio and video communication for passenger service areas.
· JR101-6B, JR204-6B & JR201-FK Station Audio Terminals
Designed with durable industrial structures, these terminals meet daily communication requirements for station platforms and railway staff. All deployed terminals feature industrial-grade corrosion resistance and impact protection, enabling long-term and reliable operation in demanding metro environments.
Project Value & Application Results
The complete communication solution established an efficient communication network connecting the control center, tunnels, platforms, and field personnel. Video terminals assist operators in quickly identifying on-site conditions, significantly improving maintenance coordination and emergency response efficiency. Since deployment, 1,200 communication terminals have been operating reliably, effectively addressing cross-location and multi-role communication requirements. The project provides a mature industrial communication solution supporting the continued development of intelligent rail transportation in Australia.
