COMMON SIGNALLING METHOD

摘要

The method implements the signal link (level 2) for the message transfer port of the full electronic exchanger. The method is implemented by the multiple signal terminal (1); the message input-output charges connected with the user port (6) through B- bus; the memory board (3) connected with the message input-output charge board through VME-bus; and the level 3 function control facility (4). The method comprises the first step that processes the signal for processor communication; the second step processing the level 3 signal; the third step processing the input signal from the other side; and the fourth step receiving the signal according to the control signal.
