摘要
An Ethernet access connection (102) connects a user access point (10) to an access node (12) in the network. The access connection comprises a passive coupler (20), by means of which a further access connection (104) can be provided between the user access point (10) and a second access node (14), such that data can be exchanged over each access connection (102, 104) between the user access point and the network. This duplication ensures that communication is not severed if the access connection (102) is breached. To avoid interference at the destination terminal (11) between the two resulting identical data streams, the access nodes (13, 18) giving access to the destination terminal are controlled such that only one of them forwards data to the destination access point (11), with the capability to switch to the other one in the event of a loss of connection between the access node (13) and user access point (10).
