Anexample method is through monitoring thestatus in one of HCI DisconnectionComplete event parameters, namely 0x08(Connection timeout). [Undefined in HFP]When link loss happens to release theService Level Connection, it isrecommended that the AG execute pagescan and the HF execute both page scanand paging, respectively.[Undefined in HFP]To ensure reconnectionfollowing undesired ServiceLevel Connection release5
