Bristol & West has signed a £4.6m deal with Telewest Business to develop and manage its wide area network infrastructure.
The five-year contract will connect the bank's 137 branches throughout the UK over an IP virtual private network (IPVPN).
The IPVPN will run voice, data and internet communication over Telewest's own infrastructure, providing a secure and resilient transfer of company data.
It will also employ Multi-Labelling Protocol Switching so that Bristol & West can prioritise traffic across Telewest's network. The cable company will be responsible for continually monitoring the service.
Tony Grace, managing director at Telewest Business, explained that the IPVPN service would "provide the efficiency, speed and security that is crucial to Bristol & West".
Keith Bustin, IS director for Bristol & West, stressed that the main business benefit from IPVPN is a safe and dependable infrastructure.
"A resilient, reliable and secure network is key to the effective running of our operation," he said. "Round-the-clock network monitoring means we can be assured that our communications are in safe hands."
Bustin added that the system is flexible and scalable so that additional branches could be added to the network as and when required.
As well as the IPVPN, Telewest will supply voice services to Bristol & West and maintain its metropolitan area network running between its sites in Bristol.
