Montreal subway telecommunications systems, STM
The STM seeks to improve customer service, better perform and meet new needs. In 2001, the STM launched an extensive program to replace some of Montreal’s subway’s fixed equipment (total investment of 311 M$ in the initial phase). This program included the replacement and modernization of all telecommunication and operation procedure control systems. The pre-feasibility study proposed an integrated vision of the systems and valued standardizing communication interfaces. Based on this proposition, a new system configuration was established and served as the basis for the implementation of advanced communication functions for the subway’s operator.
The telecommunication systems contemplated by the program included telephony, radiocommunications, public address system, remote monitoring of installations, electronic display for commuters and internal communications.
The following activities were carried out during subway operations:
-
A telephone system providing service for over 4 000 extensions (including control centre) and based on Voice over IP
-
An integraded radiocommunication system for employees and mobile support equipment for bidirectional voice-data communications, above as well as underground
-
A remote monitoring system including over 1 000 cameras deployed in more than 75 sites of which 50 or so images can be sent to the control centre
-
Passenger information systems including acoustic and electronic display equipment operated by the control centre
-
An advanced data transmission system using IP/Ethernet technologies for access, routing and signal channelling
-
Supervision consoles for all systems and integration of these into the control centre’s system
-
Cable infrastructures for site networking and equipment hook-up (several thousand components)
-
Layout of telecommunication rooms and implementation of joint equipment such as uninterruptible power supply systems.
