摘要： A laser power supply and control device for a fiber optic link between a subscriber and a telecommunications central office provides selection of one of two data sources and varies the laser current. The device includes a current generator controlled by an activation signal and delivers a laser current to a laser that can be varied. A selector circuit is connected to the two data sources. An output modulator has an input connected to the current generator which delivers the laser current thereto and to the selector circuit which delivers the transmit data. Its output is connected to the laser to which it delivers the laser current modulated by the transmit data. In the absence of data to transmit the value of the activation signal, the current generator is disabled so that the laser is not energized.

摘要： A digital interface of an integrated subscriber line interface circuit is provided. The interface serves for the connection of a signal processor unit. Individual connections are used as signal inputs in signal entry operation of the interface, and as signal outputs in signal transmission operation. Other connections are used as signal inputs in both operating mode, but receive different signals in each operating mode. One group of connections includes two registers with respective associated decoders to enable switching from one to the other, so that the number of operating instructions that can be represented by means of binary signal value combinations applied to the connections is doubled.

摘要： A digital interface between at least two subscriber line interface circuits and a processing unit is described. The interface is configured in the form of a parallel interface. The level of an input/output register and of a control register is allocated, as needed, to the connections of the processing unit. These connections can be operated selectively as inputs or outputs. They can also be operated in two modes, depending upon which type of subscriber line interface circuit (SLIC) is connected. The connections of the last-mentioned units are partially operable as inputs or outputs and partially operable only as inputs but in the input case, selectively for various types of input signals.
