[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0014] see figure 1 . A general No. 7 common channel signaling system includes a network (or P bus) 20 , a user-side processor 10 and a pair of signal terminal controllers 30 . Each signal terminal processor 30 is composed of a P bus controller 32 , a CPU (central processing unit) 34 with a timer, and a signal terminal board 36 . Each signal terminal controller 30 is on the same backplane so as to share the load under normal conditions, and when one of the signal terminal controllers 30 fails to control the signal chain of the faulty part. The P bus controller 32 makes the P bus work with the signal terminal controller 30 under the control of the CPU34. The CPU 34 controls the overall operation of the signal terminal controller 30 . The user side processor 10 is equipped with the pseudo ...
