A cross-connect having a cross-connecting processor, data memory for storing cross-connection data in cyclically recurring elements, and a control memory for storing instructions controlling the cross-connecting. The cross-connect further having a condition monitoring block arranged so as to selectively read cross-connection data from the data memory and indicate the status of a certain cyclically recurring bit or bit combination. In response to the reading of a certain instruction from the control memory the cross-connecting processor reads certain cross-connection data from a certain first source if the condition monitoring block has indicated that a certain cyclically recurring bit or bit combination is in a predetermined first state, and from a certain second if the condition monitoring block has indicated that the cyclically recurring bit or bit combination is in a predetermined second state.
