摘要： A signal distribution cable network system in which frequency division multiplexing is employed to provide a plurality of information channels. A channel allocation controller (CT) allocates free channels on request for the transport of signals from a local signal source (SS1, SS2, SS3) to a signal destination receiver (SR1, SR2, SR3) connected to the network. The local signal source includes a programmable modulator (CFS, VCO, MOD) which is set by the channel controller (CT) to operate at the carrier frequency of the selected channel. The signal level of the signals transmitted by the local signal source is measured in the controller and adjusted to compensate for signal attenuation by a command signal sent by the controlle to the programmable modulator in the local signal source.

摘要翻译：一种信号分配电缆网络系统，其中使用频分复用来提供多个信息信道。信道分配控制器（CT）根据请求分配空闲信道，用于将信号从本地信号源（SS1，SS2，SS3）传输到连接到网络的信号目的地接收机（SR1，SR2，SR3）。本地信号源包括由通道控制器（CT）设置为在选定通道的载波频率下工作的可编程调制器（CFS，VCO，MOD）。由本地信号源发送的信号的信号电平在控制器中测量，并调整为通过控制器发送到本地信号源中的可编程调制器的命令信号来补偿信号衰减。
