Abstract: An arrangement for serving an operator assistance request detected in a first operator assistance system from an operator position in a second operator assistance system. If a first operator assistance system is overloaded or has no attended operator positions, the two operator assistance systems cooperate to establish a connection between the customer requesting operator assistance and the operator position in the second system. The attending operator at that position keys information into the operator position for transmission to the first system. Responsive to this data, the first system enters data, such as billing data, into its records, and sets up connections, such as a connection for a person-to-person call, in its switching network. The arrangement can be used to transfer operator assistance requests at night, during overload, or to specialized operators not available at the first office.
