In recent months there has been an increase in technical support requests, related to lift alarms, across our industry, implying that many issues are still present related to the digital switch. Information to lift owners remains limited from BT Openreach meaning that lift owners may be at risk of not knowing if, or when, their analogue telephone lines (with copper conductors) will be replaced by fi bre connections. Many lift maintenance providers are already installing GSM systems to cover any loss in telephone coverage, but with over 10 million analogue lines still to be replaced, an increased rate of work by BT Openreach may impact where any GSM system has not yet been installed.
