Procedure for ensuring the operation of signalling channels in a v5 interface

摘要

The present invention relates to a procedure for ensuring the operation of signalling channels in a V5 interface between a local exchange (LE) and an access node (AN). The interface includes at least two links (L), in conjunction with redefinition of the interface composition. Redefinition generally involves making changes in the V5 interface data, such as the location of signalling channels on the links. According to the invention, the operation of protected channels in conjunction with restarting is ensured by starting the protected channels on the channels defined for them in the new composition and on the channels to which they were transferred in conjunction with the protection switch-over.
