Embodiment
Embodiment
As shown in Figure 1, comprise E1 interface connector and direct-connected device 6, connector is connected with direct-connected device 6 with light-emitting diode 3 respectively, and light-emitting diode 3 positive poles are connected with signal transmssion line 1, and light-emitting diode 3 negative poles are connected with shielding conductor 2; The outer surface of signal transmssion line 1 is provided with inner sheath 4, and the outer surface of inner sheath 4 is provided with outer conductor 5.Connector is connected with the E1 signal testing plug on the DDF frame, and direct-connected device is connected with the E1 holding wire of transmission or business side equipment.
Described signal transmssion line is heart yearn.
Described shielding conductor is the line skin.
Described inner sheath is insulating barrier.
Described outer conductor is screen or signal ground.
The outer surface of described outer conductor is provided with oversheath.
Operation principle of the present utility model is as follows:
Know that according to the frame structure principle of E1 interface an E1 is the link of 2.048M, use pcm encoder, the frame length of E1 is 256 bit, is divided into 32 time slots, and a time slot is 8 bit, and per second has the frame of 8k E1 by interface, and interface rate is 2048kbit/s.When like this, normal, E1 interface transmitter side has signal code and passes through.And the characteristic of light-emitting diode (being called for short LED) is forward conduction, oppositely cut-off, be operated in the forward bias state, when having forward current to pass through, LED can be by electric energy conversion luminous energy and luminous, its forward operating voltage generally is no more than 2V, forward current is about 10mA.So in test E1 interface, the signal sending end of E1 interface is connected with light-emitting diode, sending light-emitting diode under normal circumstances in device signal can be luminous, and during with the receiving terminal sub-connection, not luminous because having signal to flow to pass through.
The utility model test implementation mainly can divide three types as follows.
1, carry out the test of E1 signal on the DDF distributing frame, as shown in Figure 2, while testing on DDF frame 9, the direct-connected device of the utility model E1 interface signal tester 11 partly can be taken off, only by its main part, directly be inserted on the E1 interface testing plug of the front required test of DDF frame or socket and test, when the signal lamp person of glowing is sending out of E1 signal, the receipts that not luminous person is the E1 signal.If two interfaces of an E1 signal are not luminous or all luminous, illustrate that the tributary signal that transmission equipment 8 or business device 10 sides bring is undesired.Need check processing.
2, on test DDF frame, whether E1 signal wire jumper is normal, as shown in Figure 2, can by E1 signal wire jumper, with equipment 2M cable, the side of sending out on the DDF frame be connected, at the wire jumper opposite side, use the utility model tester to be tested, if indicator light is bright, be that wire jumper is normal, if indicator light does not work, illustrate that wire jumper welding etc. processes badly, need to again process.
During 3, without the DDF frame, transmission equipment side or business survey E1 interface signal are tested, shown in Fig. 2, the E1 holding wire that uses direct-connected device of the present utility model to send here with business device 10 both sides with transmission equipment 8 is connected, if the luminous person of indicating device is E1 signal hair line, not luminous person's take-up, should be connected sending out of transmission equipment 8 sides with the receipts of business device 10 sides, the receipts of transmission equipment 8 sides are connected with sending out of business device 10 sides, could realize the reliable docking of signal.If find during test that transmission equipment 8 sides or two lines of business device 10 side are all luminous or unglazed, illustrate that transmission equipment 8 or business device 10 side apparatus break down, mistake appears in distribution or cable is bad, can judge the abort situation place in scene, processed at once.
From top embodiment, can find out, E1 signal testing utensil has on-the-spot use test accurate, easy to connect, and method of operation is simple, and can with various E1 interface connecting tests, use flexible operation, volume little, be easy to carry.We are widely used in communication equipment construction and the work in everies such as operational trials, operation maintenance, can increase work efficiency, save and come and go working site cost used, convenient test, quick, improve communication network equipment and traffic failure processing speed, guarantee communication network safety, reliable, stable operation
.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on the technical solutions of the utility model basis, within all belonging to protection range of the present utility model.
