摘要： In the frequency-division multiplex broadband multimedia network of this invention, a plurality of transmission paths are laid out in a matrix, with transmission path switches being arranged at respective lattice points. Each transmission path switch monitors a transmission path current. When a transmission path switch detects that a current has been cut off, a portion where a communication trouble is caused is disconnected from the network, and the switch connects a portion at the downstream side of this tansmission path switch to another adjacent transmission path.

摘要： Since a transmission route is set in accordance with the number of relaying broad band switching nodes present between two terminating nodes of a plurality of broad band switching nodes, a through-put characteristic, an affecting degree due to occurrence of a defect, the traffic of the entire network is distributed. In addition, when the system is started up, transmission routes with a minimum band width necessary for routing control have been set in all the broad band switching nodes. Whenever a call takes place, a transmission route is set and the band width is variably set by using an intelligent inference mechanism. Moreover, an intelligent distributed control for distributing such an intelligent inference mechanism in the broad band switching nodes is used. Thus, the load of processing a call can be decreased, while the reliability of the network and the improvement of the operating efficiency can be achieved. Furthermore, since the private branch system interface uses a frame which consists of a control window area for controlling its transmission and a cell multiplexing area for multiplexingly transmitting cells, bidirectional transmission between the broad band switching node and a plurality of terminal equipments can be achieved with a single extension transmission line. In addition, since a frame construction which satisfies the ATM method is used, different information transmission speeds can be flexibly selected.

摘要： A projection optical system which projects an image of a first object onto a second object includes a plurality of lenses and a plurality of aperture stops for determining a numerical aperture. The plurality of aperture stops include a first aperture stop having an opening whose size can be changed, and a second aperture stop having an opening whose size can be changed. The first and second aperture stops are positioned nearer to the second object than a lens having the maximum effective diameter among the lenses included in an imaging optical system nearest to the second object. At least one of the first and second aperture stops is positioned at or near the pupil of the imaging optical system. The range of the numerical aperture determined by the first aperture stop is larger than the range of the numerical aperture determined by the second aperture stop.
