Abstract:
A method of assembling a transmission performance profile for a circuit having multiple links in a network having a plurality of circuits and at least one node having an administrative module which provides error detection for at least one circuit, the method comprising the steps of:detecting a frame within the input signal on a link; providing a frame format template compatible with the particular type of input signal, the frame format template used to generate an estimated frame signal; comparing the detected frame signal to the estimated frame signal to determine the presence of an error when the estimated frame signal does not coincide with the detected frame signal; generating a default frame signal using a synchronization circuit to maintain accurate synchronization between detection and received signal; and generating the transmission performance profile output signal comprising a series of bits depicting the integrity of the input signal at the frame level as a function of time, the output signal synchronized with the default frame signal.
