Abstract:
A cross-connect comprising:a cross-connecting processor; data memory for storing cross-connection data in cyclically recurring elements; a control memory for storing instructions controlling the cross-connection; and a condition monitoring block arranged so as to selectively read cross-connection data from said data memory and indicate the status of a certain cyclically recurring bit or bit combination, said cross-connecting processor being arranged so as to preform, in response to the reading of a certain instruction from said control memory, a certain first switching operation to certain cross-connection data when said condition monitoring block has indicated that said cyclically recurring bit or bit combination is in a predetermined first state, and a certain second switching operation to said cross-connection data when said condition monitoring block has indicated that said cyclically recurring bit or bit combination is in a predetermined second state.
