CIRCUIT AND METHOD FOR LINE SIMULTANEOUS TESTING IN A FULL ELECTRONIC SWITCHING SYSTEM

摘要

The analog subscriber circuit and line simultaneous test method in a full electronic exchange comprises the steps of: determining whether test equipment control is in normal, abnormal or unpackaged state; changing the information according to the determined result and storing the changed resu when a subscriber circuit test request is inputted, if a line test is on, changing to the circuit and line simultaneous test; and when a subscriber line test request is inputted, if a circuit test is on, changing to the circuit and line test state, to thereby select a testable subscriber test equipment.
