Accordingly the ASP00 recognizes the prefix of the inputted call and sends a routing request signal to the NTP(504). The NTP searches a route table for an ASP containing an available trunk of an associated route(506). Then the NTP notifies the ASP00 of the searched ASP having an available trunk(508).

Abstract: PURPOSE: Testing facility for a broadband communications system is provided to communicate telephony signals, and other or similar signals, over CATV and equivalent communications networks by evaluating the upstream signal spectrum and determining the effects of possible interference signals upon the upstream transmission of telephony signals. CONSTITUTION: Modulators at a headend transmit telephony signals in the forward band of the broadband communications network. The forward telephony channels are demodulated and demultiplexed by many subscriber terminals into individual telephony signals. The returning signals are digitized into standard telephony signals onto the reverse band of the broadband communications network, and demodulated by demodulators into a standard telephony signal. The test system evaluates the operating state of a selected demodulator by modulating a carrier with a predetermined data pattern to generate an upstream test signal. The upstream test signal is transmitted to the selected demodulator, which responds by outputting a detected upstream test signal. The test system compares the detected upstream test signal to the data pattern to generate error measurements. For an ingress test, the upstream signals are combined with the upstream test signal, and this signal combination is analyzed to determine the status of the selected upstream channel and the selected demodulator. The test system evaluates the operating state of a selected modulator in response to receiving a downstream test signal, outputs a detected downstream test signal in response to the downstream test signal and conducts error measurements in response to the detected downstream test signal.
