ABSTRACT:
An interruption processing system in time division multiplex transmission system executes at a central control unit a group access for accessing in batch respective groups of a plurality of terminal units in response to at least part of superior bits of a specific address for one of the terminal units which requests an interruption, causes inferior bits of the address returned from the terminal unit requesting the interruption to the central unit, and allows the central control unit to specify the interruption requesting terminal unit on the basis of the superior and inferior bits of the address. Extremely rapid specification of the interruption requesting terminal unit is thereby made achievable, and the operational response time of the transmission system can be shortened to a remarkable extent.
