Abstract: A method for conveying digital data from a transmitter (20) to a receiver (40) includes specifying a spectral filtering profile to be applied in conveying the data. A sequence of input symbols is generated (22) at the transmitter, corresponding to the data to be conveyed. The input symbols are precoded at the transmitter using Tomlinson-Harashima precoding (25) responsive to the specified profile, so as to generate a corresponding sequence of precoded symbols. The precoded symbols are filtered (26) in accordance with the specified profile. The precoded and filtered symbols are decoded at the receiver so as to recover the data therefrom.

Abstract: A Calling Number Display and Recording System stores caller identification (CID) information (148) including a caller's telephone number and other pertinent information when a called party is not present and records the CID information (148) verbally for later replay or other use. The system integrates customer-owned telephone equipment (12, 17) with CID information (148) placed on a telephone carrier (144) by Central Office equipment. A calling party termination signal, known as a "Wink" signal (146), is used as a trigger to disconnect an answering device (17) from a telephone line (14) and to place decoded CID information (148), which is processed by control logic (38), at the end of any message (155) left by the caller. The processed information (76) may be displayed visually and announced by a voice synthesizer.

Abstract translation: 呼叫号码显示和记录系统存储呼叫方识别（CID）信息（148），包括呼叫者的电话号码和其他相关信息，当被叫方不存在时，口头地记录CID信息（148）用于随后的重放或其他使用。 该系统将客户拥有的电话设备（12,17）与由中心局设备放置在电话运营商（144）上的CID信息（148）进行整合。 被称为“眨眼”信号（146）的呼叫方终止信号被用作将应答设备（17）与电话线路（14）断开连接的触发器，并且将被处理的解码的CID信息（148） 通过控制逻辑（38），在呼叫者留下的任何消息（155）的结尾处。 经处理的信息（76）可以被视觉显示并由语音合成器通知。
