Abstract
A signaling test apparatus for testing a trunk register transmitting/receiving signaling, a subscriber service signal tone, a subscriber DTMF transmitting/receiving signaling, and a CCT transmitting/receiving signaling in a switching system. The signaling test apparatus includes a computer interface for communicating with a computer, a PCM interface for communicating with the switching system, a microprocessor for receiving a test command transmitted from the computer through the computer interface and generating a control signal to perform a corresponding test mode, a test signal storage memory for supplying a plurality of test signals having a predetermined frequency to the switching system through the PCM interface under the control of the microprocessor, and a digital signal processor for analyzing the test signal which is fed back from the switching system and received through the PCM interface under the control of the microprocessor.
