SIGNAL RELYING SYSTEM

摘要

The duplicated structure signal relay system of No.7 common line signal network adopts an inter-unit interrupt processors for effective message processing and system operation. The signal relay system includes a first interrupt processor equipped in a level 2 unit for generating interrupt signal applied to a level 3 unit, a second interrupt processor equipped in level 3-3 network unit for generating interrupt signal applied to a level 3 unit, and a third interrupt processor lequipped in a level 3 unit for checking input interrupt signals using non-daisy chain and for generating interrupt signal applied to the level 2 unit and the level 3-3 network unit.
