Abstract

The invention relates to a method for realizing relay junction and calling information extraction by utilizing a digital relay voice card, belonging to the technical field of communication. The method comprises the following steps of: (1) establishing a data model; (2) circularly scanning all relay circuits by adopting time-sharing operation and carrying out calling information extraction, number analysis, signaling forwarding control, relay circuit selection, relay circuit connection, relay resource release and calling failure state processing according to a signaling state of each relay circuit and the current relay circuit state; and (3) displaying information, such as the circuit state, a calling state, a connecting channel number, a called number and a calling number of each relay circuit in real time. The method disclosed by the invention finishes a signaling forwarding process by circuit signaling state analysis and signaling sending control, realizes a function of relay junction of the digital relay voice card, ensures that a user can learn the working process and the state information of each relay circuit in time, has a flexible equipment configuration function and can be applicable to different number of voice cards of digital relay interfaces.

Description

technical field [0001] The invention belongs to the technical fields of telephone exchange and computer storage control. Specifically, it uses the existing digital trunk voice card to complete trunk status scanning, number analysis, signaling control, and trunk circuit selection through computer control and storage technology, and realizes the functions of trunk tandem and call information extraction. Background technique [0002] The development of telephone voice card technology has emerged in the United States since the early 1980s, and has been developing at a very fast speed since then. In 1988, Dialogic, a famous American manufacturer of boards and cards, entered China and dominated the market with expensive products for five years. From the second half of 1992 to 1993, some domestic manufacturers successfully developed domestic analog voice cards on the basis of absorbing foreign voice card technologies. With the expansion of market scale and the improvement of tech...
