Abstract: An intelligent network (20) provides an ability for a user (22) to customize the use of intelligent network services in an automated fashion. A service control point (32) controls operation of the intelligent network services and automatically controls how a service switch point (28) or a home location register (74) maintains a database (72) containing trigger detection point criteria that indicates when an intelligent network service should be provided. In a disclosed example, a user can use a telephone (21) or a mobile station (22) for interfacing with the service control point (32) to set up, modify or cancel an intelligent network service.

Abstract: A zigzag wavelength division multiplexer. The zigzag wavelength division multiplexer reduces the wavelength shift in the center of a frequency band caused by temperature changes. The zigzag wavelength division multiplexer includes an intermediate block, an input end and a plurality of output ends. The input end has a first sleeve and an optical collimator disposed in the first sleeve. Each of the output ends has a second sleeve, a wave filter and an optical collimator. The optical collimator and the wave filter are disposed in the second sleeve. The zigzag wavelength division multiplexer reduces use of the GRIN lens and glass ferrule, and thereby manufacturing costs.
