Abstract
In response to a testing instruction from a PHSC, the cell range of CS 4a is expanded from a range indicated by a solid line to another range indicated by a broken line in which CS 4a can communicate with CSs 4b, 4g and 4f as well as other CSs not shown adjacent to CS 4a. Under the control of the PHSC, test calls are successively produced from CS 4a and transmitted to CSs 4b, 4g, 4f and all other adjacent CSs not shown to confirm the normality of connection. Then, in a similar manner as described above, the PHSC repeats this operation successively for all CSs and confirms the normality of the CSs from obtained results. When an abnormal condition is found out in a test result, the PHSC analogizes from a combination of test routes to specify the abnormal CS.
