British Telecom and AT&T have fully unwound their Concert joint venture and completed the return of assets to the parent companies, BT announced Tuesday.
BT has also completed the termination of its Canadian joint venture with AT&T though AT&T Canada, BT said in a statement.
AT&T and BT announced last October that they were disbanding Concert, the international joint venture launched in 1998, due to continued losses which at one point came to about £20 million ($28.8 million) per week.
Former Concert customers have been split between AT&T and BT, based on their geographical location, and the two companies have signed commercial agreements to ensure that customers receive uninterrupted service, BT said.
BT now plans to use the Concert capabilities it has inherited to bring IP virtual private network managed services to 30 countries across Europe through its BT Ignite division, the company said.
In January, BT said that once Concert was fully disbanded, it would begin rolling out additional VPN services based on technologies such as IP Security (IPSec), Multi-protocol Label Switching and class of service, as a way to prioritize and manage traffic in a network.
