IT students at Nelson and Colne College Sixth Form have visited the BT Customer Experience and Management Centre at Oswestry.
The BT site at Oswestry is responsible for routing the world’s telephone traffic and the protection of 999 calls.
Students attended a presentation which outlined of BT and the history of the site.
After the presentation, the students had a chance to see the world's second largest plasma screen, which is used to display all of the telephone calls going through the network, and the monitoring of BT Vision channels.
ICT tutor Michael Cruise said it was the college’s fourth year visiting the centre, adding: “Visits such as this allow the students to gain an in-depth understanding of the workings of large companies’ IT systems and provides a real-life context to what they have been studying in lessons.”
