Adaptive processing method for common line signal processing method and channel corresponding signal processing method in digital trunk board with RA function of all electronic exchanges

摘要

In this digital trunk board, the adaptive processing method for the common line signal processing method and the channel corresponding signal processing method is a digital trunk board having a speed conversion function for providing the NO.7 path, which is a common line signaling method, In order to enable the adaptation processing by the common line signaling method and the CAS method which were previously provided, the present method is to determine whether there is a change in the mode flag when all the devices and various flags in the digital trunk board are initialized Checking whether the mode is a certain type, if there is a change in the mode flag, and if the mode is a common line signal processing method, performing a functional processing of the digital trunk board on the common line signal processing system If the mode is the channel corresponding signal processing method, performing the corresponding function processing It characterized in that it comprises.
