Abstract: An interface card adapted to be mounted at the back plane of a splitter chassis. The interface card includes card edge connectors for providing connections with a splitter card. The interface card also includes cable connectors for inputting mixed voice and data, and for outputting data and voice signals. Tracings are provided on the interface card for interconnecting the cable connectors and the card edge connectors. The tracings are configured such that first tracings carrying data signals from the splitter card to the cable connectors do not cross second tracings carrying voice signals from the splitter card to the cable connectors.

Abstract: REGULADOR DE CONEXION DE AMPLIFICADORES PARA EMPLEAR EN UN SISTEMA DE TRANSMISION POR CABLE "HEADEND" (RECEPTOR-DISTRIBUIDOR DE SEÑALES) QUE DISPONE DE AMPLIFICADORES PRIMERO Y SEGUNDO, ASI COMO DE PISTAS DE ENTRADA Y DE SALIDA DE LOS AMPLIFICADORES CONECTADAS A UNO DE LOS AMPLIFICADORES PRIMERO Y SEGUNDO, QUE SE CONVIERTE EN EL AMPLIFICADOR ACTIVADO EN EL MOMENTO. EL REGULADOR DE CONEXION DE AMPLIFICADORES COMPRENDE UN SELECTOR DE ENTRADA PARA TOMAR MUESTRAS DE UNA SEÑAL COMBINADA EN LA PISTA DE LA SEÑAL DE ENTRADA Y PARA MEDIR EL NIVEL DE LA SEÑAL DE ENTRADA. EL REGULADOR CONTIENE TAMBIEN UN SELECTOR DE SALIDA PARA TOMAR MUESTRAS DE LA SEÑAL COMBINADA AMPLIFICADA EN LA PISTA DE LA SEÑAL DE SALIDA, ASI COMO PARA MEDIR EL NIVEL DE LA SEÑAL DE SALIDA. UN MEDIO PROGRAMADOR RECIBE LOS NIVELES DE LAS SEÑALES DE ENTRADA Y SALIDA Y DETERMINA SI EL AMPLIFICADOR ACTIVADO EN AQUEL MOMENTO FUNCIONA O NO ADECUADAMENTE. SI NO FUNCIONA ADECUADAMENTE, EL MEDIO PROGRAMADOR GENERA UNA SEÑAL DE CONTROL PARAUN INTERRUPTOR Y EN RESPUESTA A LAS SEÑALES DE CONTROL, EL INTERRUPTOR DESCONECTA LAS PISTAS DE SEÑALES DE ENTRADA Y DE SALIDA PROCEDENTES DEL AMPLIFICADOR QUE ESTA ACTIVADO EN EL MOMENTO Y CONECTA CADA UNA DE LAS PISTAS DE LAS SEÑALES DE ENTRADA Y DE SALIDA A OTRO DE LOS AMPLIFICADORES PRIMERO Y SEGUNDO.

Abstract: An amplifier switch controller is provided for use in a headend cable transmission system having first and second amplifiers and amplifier input and output paths connected to one of the first and second amplifiers, which becomes the currently activated amplifier. The amplifier switch controller comprises an input sampler for sampling a combined signal on the input signal path and measuring an input signal level. The amplifier switch controller also comprises an output sampler for sampling the amplified combined signal on the output signal path and measuring an output signal level. A program means receives the input and output signal levels and determines whether the currently activated amplifier is not functioning properly. If it is not functioning properly, the program means generates a control signal to a switch. In response to the control signals, the switch disconnects the input and output signal paths from the currently activated amplifier and connects each of the input and output signal paths to the other one of the first and second amplifiers.

The amplifier switch controller comprises an input sampler for sampling a combined signal on the input signal path and measuring an input signal level. The amplifier switch controller also comprises an output sampler for sampling the amplified combined signal on the output signal path and measuring an output signal level. A program means receives the input and output signal levels and determines whether the currently activated amplifier is not functioning properly (eg by determining whether the gain lies within a predetermined range). If it is not functioning properly, the program means generates a control signal to a switch. In response to the control signals, the switch disconnects the input and output signal paths from the currently activated amplifier and connects each of the input and output signal paths to the other one of the first and second amplifiers.
