Description

A kind of signaling monitor device

Technical field

The utility model belongs to communication technology application, particularly a kind of signaling monitor device.

Background technology

In the communications field, often need monitoring signaling: DSS1, NO1, NO7 etc.Assist personnel such as engineering, research and development to carry out signalling analysis, so that problems such as solution signalling interworkings.General signaling monitor equipment volume is huge, heavy, is inconvenient to carry, and can only monitors at a kind of signaling, very dumb.

Summary of the invention

The purpose of this utility model is to disclose a kind of signaling monitor device at the problems referred to above.

Described device is made up of signal collecting interface, signaling control switch, signaling channel switch, signaling output interface and CPU.CPU is connected with signal collecting interface, signaling control switch, signaling channel switch, signaling output interface respectively.

Described signal collecting interface is composed in series by E1 chip and hdlc controller, and the model of E1 chip is DS21Q59, and the model of hdlc controller is PT7A6525.

Described signaling control switch is the toggle switch of one 8 bit, and two values (ON, OFF) of each dial-up are encoded to 0,1 respectively, and span is 0-255.

Described signaling channel switch is the toggle switch of one 8 bit, span 1-31.

Described signaling output interface is the interface that a serial ports changes USB.

The beneficial effects of the utility model are:

1) this apparatus structure is simple, volume is little, and is in light weight, is easy to carry

2) interface of this device is a general-purpose interface, does not have compatibility issue.

3) the output result of this device is convenient to people's understanding, need not strongly professional knowledge.

Embodiment

Shown in Fig. 1-4, the step that this device is monitored signaling is as follows:

1) the E1 chip is connected with the device outside line, and receive signaling and it is carried out encoding and decoding,

2) the signaling control switch is indicated the signaling type that this device will be gathered.This switch is the toggle switch of one 8 bit, and each dial-up has two values (ON, OFF) to be encoded to 0,1 respectively.This switch can be provided with 0-255 value, and each value can be represented an indication, only uses 3 value: 0-NO1 at present; 1-DSS1; 2-NO7.

3) signaling channel switch and signaling control switch are used, and when signaling control switch indication signaling type was DSS1, NO7, this switch connected the corresponding time slot passage on the E1 chip interface by CPU.The signaling channel switch is the toggle switch of one 8 bit, span 1-31.

4) hdlc controller will link to each other with the time slot passage on the E1 chip interface, finishes the collection of original signaling data, and the model of E1 chip is DS21Q59, and the model of hdlc controller is PT7A6525.

5) which kind of signaling CPU adopts resolve according to signaling control switch decision, and will receive the original signaling data of hdlc controller and it is resolved, and converts text formatting then to and outputs to the signaling output interface.

6) the signaling output interface is the interface that a serial ports changes USB, and this interface is directly received on the PC, as long as the serial ports receiving software that uses PC operating system to carry can receive signaling information.
