(1) Realize digital time division exchange and enable speech signal and signaling signal to realize full digitalization in the whole exchange process with high talking quality and stable system operation. It is more close to modern program control exchange principle.
(2) Connect experiment apparatus and PC through standard serial port; achieve the purpose of managing users through PC software to program control exchange system’s setting. PC software interface is humanization with rich function and stable operation, so that the experiment apparatus is mire close to a small scale program control exchange machine.
(3) Adopt speech record play chip of high quality. When exterior line call in the experiment apparatus, the recorded voice will prompt all users’ numbers in the experiment apparatus, which makes the function of exterior line more humanization.
(4) Four users in the experiment apparatus can communicate with the telecommunication network, either call in or call out. Analog communication could be processed between two experiments through trunk wire.
(5) Adopt plexiglass baffle for protection
