In a method of routing audio or video data, source data inputs to input modules are divided into groups and each main crosspoint module receives one group from every input module, and destination data outputs from output modules are divided into groups and each output module receives one group from every main crosspoint module. Input modules send a duplicate of one selected group to a redundant crosspoint module and output modules receive a group from a redundant crosspoint module and can use that group in place of any group from a main crosspoint module.
