Docklands Light Railway is set to replace its announcements system with VoIP-based technology.

The London railway will work with Serco Docklands and subcontractor Telent to implement the network upgrade, installing a new local area network to improve performance.

The network will cover all 32 DLR stations, and uses ASL iPAM public announcement systems and Cisco gigabit ethernet switches. iPAM systems are already used on 76 London Underground stations.

Work has already begun on the project, and is expected to be completed this year. The aim is for the network to last for at least 10 years.

It will be run by a Linux-based control centre, and integrated with customer display systems.

Michael Evans, communications engineer at Serco Docklands, said the contract, for which a value has not been disclosed, was “competitively priced” and would allow for increases in bandwidth if necessary.
