Embodiment Construction

[0032] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. For clarity, like numbers refer to like parts in the drawings. Although specific embodiments such as flow chart details and the like are illustrated in detail and described in order to clarify the subject matter of the present invention, those skilled in the art can also implement the present invention without these details based on the description of the present invention. Also, detailed descriptions of well-known functions and constructions are unnecessary here.

[0033] In the all-electronic switching system shown in FIG. 3, the host is connected to the RSM by means of a data link (or connection link). When the data link between the host and the RSM is in a normal state, each corresponding component works in the manner described in conjunction with FIG. 1 . In addition, in order to enable the call service between the internal users of the RSM...

Abstract

Proposed gear to process calls in remote subscriber's module of electron commutation system is related to communication systems in which remote subscriber's module is connected to main switching center by means of connecting communication line. Gear to process calls includes interface with subscriber's line which has functions of reception of phone number and function of tone signals and can process calls between in-house subscribers of remote subscriber's module even if connecting communication line between main switching center and remote subscriber's module is out of order and processor of remote subscriber's module to receive and analyze phone number, to send required tone signals, to transmit and receive special digital information that functions as processor of access commutation of main switching center if connecting communication line between main switching center and remote subscriber's module is out of order.

Description

technical field [0001] The present invention relates to a full electronic switching system, in particular to a remote subscriber module capable of processing each internal remote terminal even in the case of a connection link failure between the host computer and the remote subscriber module in the full electronic switching system. A call processing device for a call between users and a method related thereto. Background technique [0002] A fully electronic switching system provides call connection services not only to short-distance user groups but also to small groups of far-end users. When the service object is a short-distance user, the call connection service is directly provided by the host, and when the service object is a remote user, the call connection service is provided by installing a remote subscriber module (hereinafter referred to as RSM) at a distance and connecting the trunk line to the host. Figure 1 schematically shows a general all-electronic switching...
