Crossbar SendersThe functions of the crossbar originating senders thus far explained have been based on the assumption that the call was to a crossbar dial office. These sender circuits are, however, arranged for all possible conditions, such as for calls to a panel or manual office. In such instances the sender guides the panel selectors in completing a call to a panel office or operates a call indicator (page 380) in a manual office.
