A Belfast company has signed a three-year deal extension with telecommunications giant BT.
Asidua, which employs over 120, is headquartered in Belfast and has offices in Dublin and Birmingham.
The contract builds on an existing two-year deal and aims to help BT simplify the process used by its global enterprise customers to order networked IT services.
The systems Asidua is helping to develop enable BT's multi- national customers to order complex network configurations for BT IP Connect services.
The service connects enterprises' operations providing speed, availability, reach and network intelligence, helping boost applications performance while reducing costs.
Asidua's other clients include the PSNI, NEC and council authorities including Harrow in London and Chorley in Lancashire.
Asidua's chief executive Steve Brankin said the firm has been a supplier to BT for several years.
"This current relationship has helped create opportunities for our company to be involved in other projects which underpin initiatives at the very forefront of the BT IP Connect global network strategy," he said.
"BT is at the leading edge in providing and provisioning global network capability for the biggest organisations in the world and we have ambitions to collaborate with it in developing systems to support the ever changing needs of those customers."
Ashish Gupta from BT Global Services said that as BT continues to compete in vital global markets it is key that the firm provides customers with a dynamic, agile and robust infrastructure.
"Asidua has proven its ability to work alongside BT, assisting us in building and transforming the IT systems that enable us to connect customer networks worldwide even for the most challenging of sectors such as financial services," he said.
