Claims (3)

ASS (Access Switching Suvsystem) (3) which performs call processing function by subscriber and relay line matching device, time switch, and various signal devices, and spatial switch function, number translation, routing function that connects ASS (3) INS (Interconnection Network Subsystem) (2), and Central Control Subsystem (CCS) (1) that manages system-level operation management, maintenance, billing, statistics, hard disk management, and I / O devices. In the method of translating the called number of the electronic exchange; In the first step (figure 2), which consists of a double linked list structure for the called number translation for maximum flexibility in number planning and numbering system. A second step of determining whether the number is accepted in the system (Fig. 3), a third step (33, 34, 35) of obtaining and analyzing the type of the incoming line, and a general call service according to the result of the type analysis of the incoming line, And a fourth number (36 to 46) of determining the information for the automatic branch exchange hunting and the digital hose service. The method of claim 1, wherein the second step of determining whether the called number is received in the system (step 3) comprises storing the called number and the called number translation start point when an incoming number translation request is input (21, 22). Analyzing the received digits one by one from the first digit one by one to determine if the called number is accepted in the system, and changing the called number and notifying the called number if it is not accepted (23, 24, 25, 26, 27, 28). (31,32) and if it is impossible to determine whether the received number is accepted in the system even after analyzing the received digits in the translation request, obtain the length of the digit required for analysis, receive the digit as much as the digit length, and then request translation. Called number translation method, characterized in that performed by the step (29,30) requesting that. The fourth step (36 to 46) of processing according to the type of the incoming line is to obtain the incoming processor number and line number for the general call service when the incoming line is a general subscriber line, Obtaining the incoming line occupancy request to the general subscriber call processing block (36, 37, 38), if the incoming line is the automatic branch exchange line, obtain the processor number and the line number for the automatic branch exchange hunting, and the called number is automatically Analyzing the representative number or individual number of the premises exchange group, determining the premises exchange group number, obtaining billing information, and requesting hunting (39, 40, 41, 42, 43) and the incoming line is a digital subscriber line. In the case of obtaining the incoming processor number, the incoming line number, and the billing information for the digital call service, and performing the digital incoming processing request (44, 45, 46). Called number translation method wherein the. ※ Note: The disclosure is based on the initial application.
