PCT No. PCT/FI95/00528 Sec. 371 Date Mar. 26, 1997 Sec. 102(e) Date Mar. 26, 1997 PCT Filed Sep. 26, 1995 PCT Pub. No. WO96/10312 PCT Pub. Date Apr. 4, 1996The operation and maintenance network of a telephone network system comprises a plurality of operation and maintenance (OM) units for operation and maintenance of the telephone exchange connected thereto, and an operation and maintenance center (OMC). The center comprises a data communication unit (DCU) for receiving the information collected by the exchanges, and for routing it to the I/O device of the data management unit (DMU) corresponding to the logical device connection determined in a logical routing task. Upon adding new device units to the operation and maintenance center, the changes to the routing are made in a specific substitution table, and routing is performed by means of forced control to the I/O device indicated by the substitution table. If there is no change, the incoming information is routed to the physical I/O device corresponding to the logical device connection determined in the routing task. |
