Abstract

A method for providing an uplink over an access ring (1) comprising access devices (2) and at least one aggregation device, wherein each device of said access ring (1) has ring interfaces connecting said device to neighboring devices in said access ring (1) , wherein one access device (2) of said access ring (1) is configured as a ring master device (4) which sends connectivity check messages (CCM) on both its ring interfaces around said access ring (1) to itself to detect a connectivity failure in said access ring (1), wherein said ring master device (4) changes a state of one of its ring interfaces depending on the detection result.
