METHOD FOR ADAPTIVE PROCESSING ABOUT THE CAS AND CCS IN THE DIGITAL TRUNK BOARD WITH RA(RATE ADAPTATION)FUNCTION OF FULL ELECTRONIC SWITCHING SYSTEM

摘要

In this digital trunk board, the adaptive processing method for the common line signal processing method and the channel-adaptive signal processing method is a digital trunk board having a speed conversion function for providing the NO. In order to enable the adaptive processing by the common line signaling method and the CAS method provided before, this method checks whether there is a change in the mode flag when all devices and various flags in the digital trunk board are initialized. Checking whether a mode is present if there is a change in the mode flag; if the mode is a common line signal processing method, performing processing of the digital trunk board for the common line signal processing method. If the mode is a channel-compatible signal processing method, performing a corresponding function processing It characterized in that it comprises.
