Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The basic idea of ​​the present invention is to extract correct signaling data by automatically adapting to changes in signaling and voice time slots in the E1 interface and changes in signaling rate types, so as to realize the configuration of the central processing unit 202 and realize the control of all input E1 ports. The signaling scanning function of all time slots, so as to avoid the problem that the data of the signaling time slots cannot be collected correctly or comprehensively.

[0029] Among them, E1 interface includes ordinary 64Kbps, high-speed 2Mbps, N*64Kbps and ABIS interface (that is, the communication interface between BTS and BSC) and so on. As attached figure 1 , E1 interface is sent to E1 interface collection equipment after DDF rack.

Abstract

The invention provides an E1 interface data collection device with time slot scanning function. The device comprises a clock processing unit, an E1 input interface unit and a central processing unit, wherein the clock processing unit provides clock processing reference for the E1 input interface unit and the central processing unit; the E1 input interface unit realizes the code type transformation of an input E1 signal and then sends to the central processing unit; and the central processing unit scans and collects all the input signaling data. Meanwhile, the invention provides an E1 interface data collection method with the time slot scanning function, by the use of the device and the method, the signaling and voice time slot changes in an E1 interface and the signaling rate type changes can be automatically adapted to, thereby extracting the accurate signaling data and further avoiding the problem that the signaling time slot data can not be accurately or comprehensively collected.

Description

Technical field [0001] The invention relates to the field of data acquisition, and in particular to an E1 interface data acquisition device and method for realizing the time slot scanning function. Background technique [0002] The E1 interface is a pair of coaxial cables from the switch. The data transmission rate on the cable is 2.048Mbps (2M), which can accommodate 32 timeslots*64Kbps voice or signaling data at the same time. The main function of the E1 interface data collection equipment is to complete the signaling collection of the signaling time slot input to the E1 link and part of the signaling filtering. It is widely used in the No. 7 signaling centralized monitoring system. As attached figure 1 , The E1 signaling link of the bureau is transferred in the DDF frame after high-impedance jumper, and the transferred signaling link is directly connected to the E1 interface data acquisition equipment. [0003] The traditional E1 interface data collection equipment collects t...
