Embodiment Construction

[0028] The basic idea of ​​the present invention is to make full use of the characteristics of the loop relay interface and the powerful calculation capability provided by the computer, and realize the basic functions of the analog pager by means of software simulation.

[0029] In order to realize this inventive idea, as figure 1 As shown, a PC is connected to two loop relay interfaces through the RS232 serial interface: loop relay interface 1 and loop relay interface 2. These two loop relay interfaces are respectively connected to two common electrical interfaces on the digital program-controlled exchange under test. The two loop relay interfaces are responsible for sending and receiving the telephone signals simulated by the PC in this analog pager. For the program-controlled exchange, there is no difference between the simulated telephone signal it receives and the signal when dialing from an ordinary telephone, so the program-controlled exchange will respond according t...

Abstract

The calling simulator is connected to the tested digital SPC exchange from outside; a computer is connected to the loop relay interface which is connected to the interface the tested SPC exchange. The invention can use the loop relay interface to initiate a simulated calling and make a simulated answering.

Description

technical field [0001] The invention relates to an analog pager, and also relates to a method for realizing the function of an analog pager by utilizing a computer and a loop relay interface on a digital program-controlled exchange, belonging to the technical field of communication testing. Background technique [0002] The analog pager is a special test equipment for testing and evaluating the traffic processing performance of the program-controlled exchange. It is connected to the system under test through the trunk interface connection, accurately simulates the behavior of telephone users on the circuit interface of the program-controlled exchange, and uses the standard communication protocol to initiate a call to the device under test in order to test the relevant indicators of the device under test. Get the detection statistics report of the switch response, help the tester to analyze and evaluate the comprehensive performance of the switch. [0003] For scientific res...
