Poundshare The core network contains core fibre cables between main core switches which is maintained by OpenReach. Also one of BTs biggest customers are the mobile players. When your phone mobile call or data request hits the mast it daisy chains via fibre cable back to the main players switches and those switches go back to main hubs, some via more fibre cable. Some will go via radio links but Openreach are involved in the core elements of core cabling.
