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: A system and method for electronically identifying connections established through a cross-connect system provides for the identification of all hardwired and temporary patch connections, and any modifications made to existing cross-connect circuit connections. Connection identification and status information is acquired in near real-time and stored in a database which is accessible by a user through a graphical user interface (GUI). The TRACE or lamp wires which connect respective pairs of cross-connect circuits are utilized in an unconventional manner so as to form a scanning bus. The information signal paths established through the cross-connect circuits remain undisturbed. A scanning signal is communicated between each pair of crossconnected circuits over the TRACE conductor. In the event a patch cord is used to temporarily redirect a signal connection, the scanning signal is transmitted over the shield or sleeve conductor of the patch cord. The scanning signal provides identification and other information concerning the transmitting circuit. A circuit receiving the scanning signal communicates its identification information and that of the transmitting circuit derived from the scanning signal to a central computer. The identification information acquired by the central computer from all receiving cross-connect circuits provides identification and status information for all circuits within the cross-connect system. In one embodiment, all circuits of a cross-connect system are scanned and identification information acquired in the time required to transmit a single cross-connect circuit ID bit string, irrespective of the total number of cross-connect circuits included within the cross-connect system.

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 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.
