KANATA, Ontario--(BUSINESS WIRE)--Sept. 1, 1999--

CrossKeys Systems Corporation (Nasdaq: CKEY; TSE: CKY) today announced that British Telecommunications (BT) has selected CrossKeys Resolve(r) Ni software to manage the performance of BT's growing networks.

The sale was through Marconi Communications Ltd., a U.K. based leader in telecommunications solutions. This is a significant commercial deployment of CrossKeys latest software application in the CrossKeys Resolve portfolio.

"CrossKeys provided the best carrier-scale solution to manage the performance of BT's multi-technology and multi-vendor network," said John Gorbutt, Marconi Communications BT Broadband Account Manager.

For BT, CrossKeys Resolve Ni software will report on Asynchronous Transfer Mode (ATM) and Frame Relay statistics drawn from Newbridge and Cisco equipment. The contract initiates a multi-year agreement for CrossKeys, Marconi and BT.

BT contract and project manager, M. Asif Anwar said, "Our ambitious growth plans demand a high capacity scalable product and Resolve will ensure we maintain optimum levels of bandwidth and high service availability."

"Being selected by leaders like BT and Marconi demonstrates the business value of CrossKeys software and our maturity in the industry," says Ian McLaren, President and Chief Executive Officer, CrossKeys. "This is a major win for CrossKeys. It matches our strengths in scalable, multi-vendor, multi-technology software against the challenges offered by the complexity BT's network."

CrossKeys Resolve Ni analyses BT's network from an operations view, allowing BT to manage network performance rather than simply monitoring network faults or outages. With CrossKeys Resolve Ni software, BT has a better view of telecom traffic inside its network, allowing it to continuously improve service to its customers and plan for future growth.
