1. A method of changing an Interconnecting ring, from Interconnect-Open to Interconnect-Closed state, wherein the Interconnecting ring comprises a Media redundancy Interconnection Manager, MIM, and at least three Media redundancy Interconnection Clients, MICs, the MIM being in a Link Check, LC, mode, the method comprising, upon the Interconnecting ring being in an Interconnect-Open state:
receiving by the MIM a first one of a first set of Interconnect Link Up, INLNK_UP MRP, frames sent by any one of the MICs;
sending by the MIM a second set of INLNK_UP MRP frames with a predetermined period between INLNK_UP MRP frames; and
changing by the MIM to a Check Interconnection, Interconnection Closed State, CHK_IC, state and the Interconnecting ring to an Interconnect-Closed state, if the MIM receives:
one of the INLNK_UP MRP frames from the second set; or
a second INLNK_UP MRP frame from the first set.
