摘要： A communication signal suppressing apparatus capable of reducing a load of a firmware using portion is provided in a communication signal apparatus such as a common line signal apparatus. A common line signal processing circuit corresponds to hardware used to execute a portion of the level-2 process operation, and this common line signal processing circuit owns such a function capable of discarding a reception frame having no meaning other than a confirmation response, and also capable of extracting a reverse-direction sequence number thereof. As a result, the common line signal processing circuit performs a remaining level-2 process operation. Thus, since a workload of a processing apparatus (CPU) using the firmware can be reduced, this firmware can be designed with sufficient capacities. Also, other process operations can be carried out by this CPU.
