In-service activator for a broadband exchanger

An in-service activator for a broadband exchanger, comprising:

• a dual pair of systems comprising a first system and a second system, wherein one of the first and second systems is an active system and the other system is a to-be-activated standby system and wherein each system comprises:
• channel converter means, in which channel setting information is stored, for receiving a cell from an input line, storing in the cell channel setting information and transmitting the cell containing the channel setting information, and
• switcher means for receiving the cell from the channel converter means analyzing the channel setting information and switching path of the cell based on the channel setting information;
• and
• interfacer means for storing, in the channel converter means of the to-be-activated standby system of the dual pair, the channel setting information read from the corresponding channel converter means of the active system of the dual pair;
• a first processor controlled by the interfacer means to read the channel setting information from the channel converter means of the first system and to store in the channel converter means of the second system the channel setting information read from the corresponding channel converter means of the first system;
• and
• a second processor controlled by the interfacer means to read the channel setting information from the channel converter means of the second system and to store in the channel converter means of the first system the channel setting information read from the corresponding channel converter means of the second system.
