ABSTRACT:
The present invention refers to methods and apparatuses for providing synchronization in a time division multiplexed network, wherein data is transferred on multi-access bitstreams in circuit-switched channels that are defined by respective time slots of regularly recurrent frames of said bitstreams, said frames being defined by regularly recurrent frame synchronization signals transferred on said bitstreams. According to the invention an auxiliary regularly recurrent frame synchronization signal is generated and selected as a basis for defining said frames on a bitstream if the frame synchronization signal that is used as a basis for synchronizing said frames during normal operation is not detected in accordance with an expected frame rate.
