Interactive response systems () of call centers for giving users access to information comprise means () for receiving activation signals via audio or video or audio/video calls from the users and means () for transmitting menu signals to the users and means () for receiving selection signals from the users are provided with means () for transmitting video signals to the users for providing video to the user. This video may have entertaining, explaining, supporting and/or commercial functions and makes the interactive response systems more-sided and user friendly. The users either use two different devices () or use one device () for exchanging audio and for receiving video. The interactive response systems () further comprise means () for receiving link signals that provide direct or indirect links from the interactive response systems () to the devices () or to video or audio/video calls with the devices (). The devices (-) comprise means () for transmitting selection signals to the interactive response systems () for making selections within menus.

Interactive response system for giving a user access to information

A passive filter arrangement and a method of providing such a filter is described. The frequency response of the filter arrangement is substantially the same as the frequency response of a first filter of an order having a first value, the frequency response of the first filter being representable by a first set of one or more poles and/or one or more zeros. Descriptions of a plurality of second filters are generated, each second filter having an order lower than the order of the first value, each second filter having a frequency response representable by a one or more poles and/or one or more zeros, the one or more poles and/or one or more zeros of each lower order filter being a subset of the first set. The lower order filters are cascaded.

The invention relates to a method for distributing electric power in telecommunication central office equipment intended to operate at voltages within a determined range, according to which method the voltage of the distributed power is allowed to drop temporarily below the lowest voltage of the range.

A low-pass filter arrangement associated a clamping circuit for limiting unwanted transient signals to be transmitted through the filter. Mainly the variations (dI/dt) of the current flowing through the filter are eliminated. The filter may form part of a splitter used in an ADSL system to separate low frequency POTS signals from high frequency ADSL signals simultaneously transmitted over a same copper twisted-pair transmission line. The filter comprises the series connection of a coil and the main path of a transistor of which the gate terminal is connected to the opposite end of the coil. In an ADSL system, a classical 7th order low-pass filter may advantageously be replaced by a 3rd order filter arrangement.
