When sending out packet on the 4th E1 circuit, its E1 flow watch window as shown in Figure 6, the now reception of circuit sends state as shown in Figure 7, if the 4th the receiving terminal flow of E1 circuit is less than preset value, and the 3rd the receiving terminal flow of E1 circuit increases, and with the 4th E1 circuit on send out packet gap be less than preset value, thus, can locate fault.For example, from Fig. 7, observe, send out packet on the 4th circuit, total bit traffic is 806624bps, and the bit traffic of receiving terminal only has 384bps on the 4th circuit, and the bit traffic drastic change of the 3rd E1 receiving end at this moment becomes 799984bps; After stopping PING packet, its bit traffic immediate recovery is to the state shown in Fig. 3.
By said process, can judge: the cable side at base station E1 circuit external interface occurs crossed pair fault upward to the 3rd E1 circuit between the lower port of DDF frame and the 4th E1 circuit i.e. TX2/RX3, the crossed pair fault of TX3/RX2.
The invention allows for a kind of fault location system based on Abis interface loop device, this system comprises: Abis interface loop device; This system is carried out node port loop by Abis interface loop device, in conjunction with the indicator light blink states of base-station transmission circuit board, or, in conjunction with the flow information of OMC webmaster monitoring and the flow information of a packet test, the fault in base station equipment is positioned.
