Inverclyde Council has implemented an advanced £3m fibre-based network to save on its communications costs.
The network supports a voice over IP service and a high-bandwidth Ethernet virtual private network for 5,000 staff.
The council says it will make a return on investment with the network within three years.
Inverclyde Council went to ntl:Telewest Business to deploy the network. The Ethernet VPN fibre network is more robust and reliable than the old legacy system and will serve the future modernisation and efficiency agenda of the council.
Voice over IP will provide free internal calls on the network and communications billing procedures have also been simpified.
Gordon McLoughlin, head of ICT and business transformation at Inverclyde Council, said, "The network is absolutely the foundation on which Inverclyde Council will grow its technical strategy.
"We now have the flexibility to provide scaleable bandwidth to all of our council and school buildings. We expect to reduce our revenue payments by £120,000 a year, every year for the next five years.
