The present invention relates to a method for tracking a register signaling of an exchange system, and more particularly, to a method for monitoring and tracking an R2 signaling that transmits a caller number to a called party in a key phone system and notifies the caller of the called party. will be.

In general, the R2 signaling of the exchange system is designed based on the recommendations of the CCITT, and the meaning of the signals required by the countries is slightly different. In addition, the R2 signaling signal transmission method uses a compelled signaling method. The signal processing procedure uses the digit transmission from the calling subscriber to accumulate digits, and a sufficient number of digits are available for call connection. Connect to and process the signal according to the forced signal method.

In addition, the R2 register signal is classified into a forward register signal and a backward register signal, and the forward register signal is classified into group I (selection signal) and group II (signal service class or type indication signal). Classify The Group I forward signal is shown in Table 1 below.

    Name              meaning  I1 to I10  Digit 1-0     I11  Access to incoming operator     I12  Request not accepted access to operator     I13  Access to test equipment Satellite Links Not Included     I14  Incoming Semi-Suppressor Required Satellite Link Included     I15  end of pulse

    The Group II forward signal is shown in Table 2 below.

    Name              meaning     II1  Unpriority subscribers     II2  Priority subscriber     II3  Maintenance unit     II4  Spare     II5  Operator     II6  Data transfer     II7  Subscriber (or operator without forward equipment)     II8  Data transfer     II9  Priority subscriber     II10  Operator with forward transmission equipment   Ⅱ11-Ⅱ15  Spare

Further, the backward register signal is classified into group A (confirmation and control signal of the forward signal) and group B (confirmation of forward signal and the status or class indication signal of the called subscriber line). The meaning change from the group A signal to the group B signal is a signal whose meaning changed to the group B by the A3 signal is not reduced to the group A. The group A backward signal is under a specific state of the group II signal if necessary to identify the group I signal as shown in Table 3 below.

    Name              meaning      A1  send next digit      A2  send last but one digit      A3  Address completion, group b signal conversion      A4  Domestic network congestion      A5  Caller ID Signal      A6  Address Completion, Billing, Call Status      A7  send last but two digit      A8  send last but three digit      A9  Spare      A10      A11  Send country code display      A12  Send language or determination digits      A13  Line type signal      A14  Echo suppressor usage information request      A15  International Exchange Burden

The group B backward signal confirms the group II signal as shown in Table 4 below, and the A-3 signal is preceded. Transmit switch status, subscriber line status.

    Name              meaning      B1  Spare      B2  Send special information tone      B3  Subscriber busy      B4  congestion      B5  Number      B6  Subscriber line busy, billing      B7  Subscriber line busy, non-charged      B8  Subscriber line      B9  Spare      B10      B11      B12      B13      B14      B15

This R2 register signal is set to the exchange using a PC at the terminal as shown in FIG. In addition, the exchange outputs an R2 signal tracking signal as shown in Table 5 so that an R2 signal can be tracked when a fail port occurs.

The terminal is set to the exchange by using a PC, and the signal type is transmitted and received only by one digit without the signaling system that can distinguish backward or forward signals, so only the fail port, not the entire port, is an R2 signaling message. Can be tracked.

However, as described above, the setting for tracing R2 signaling is possible only with a PC connected to an exchange, and it is not easy to monitor accurate signaling with a signaling system that is transmitted and received to only one digit, and there is a problem in that signaling messages of all ports cannot be traced.

Accordingly, an object of the present invention is to provide a signaling tracking method that can be configured to enable the R2 signal tracking in the key phone system, and to accurately identify the R2 signal message by selecting individual ports and all ports.

In the Alto signaling tracking method in the keyphone system of the present invention for achieving the above object, a process of setting the R2 signal tracking function by the MMC using the keyphone terminal, and after setting the R2 signal tracking function, the signal in the call task Sending an R2 trace-on signal in a R2 procedure message to a processor and transmitting a digit for the telephone number, transmitting and receiving an R2 forward and backward signal after transmitting the digit for the telephone number, and forwarding the R2 omnidirectional signal; And when the R2 signaling is completed by transmitting and receiving the backward signal, formatting the R2 time and the R2 signal and outputting the R2 signal to the monitor of the personal computer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

3 is a control flowchart for tracking R2 signaling according to an embodiment of the present invention.

2 to 3, the operation of the preferred embodiment of the present invention will be described in detail.

First, in step 101, the R2 signal tracking function for each trunk line is set using MMC {Man Machine Communication} in the key terminal connected to the key phone system. At this time, all ports or only fail ports are selected. Here, the R2 signal setting is the R2 caller number and class request (CLG_NUM_REQ), R2 caller status response (CLD_STS_RESP), R2 caller number and class response (CLG_NUM_RESP), and R2 caller status when the R2MFC signal option is selected by MMC in the phone terminal. Select whether to request (CLD_STS_REQ), R2 caller ID number or extension number response (CLG_EXT_RESP). In other words, the keypad terminal provides R2MFC signal options that can be set by the MMC. The R2MFC signaling options provided include R2 Caller ID and Class Request, R2 Caller Status Response, R2 Caller ID and Class Response, R2 Caller Status Request, and R2 Caller Line or Extension. Thereafter, the user selects the determined value of the R2MFC signal options through the MMC, and the key phone system corresponds to the selection through the MMC, whether the R2 calling party number and class request, R2 caller status response, R2 Caller ID and class response, R2 caller status request, R2 caller line or extension number are set. Then, in step 102, the key phone system checks whether the R2 signal trace message is on in the R2 Seizure message sent from the call task to the signal processor, and if the R2 signal trace message is not on. Proceed to step to process the error and terminate the operation. However, if the R2 signal tracking message is in the ON state, the flow proceeds to step 104 to check whether the digit is transmitted. If the digit is not transmitted, the flow proceeds to step 105 to release R2 and terminate the operation. However, if the digit is transmitted, the flow advances to step 106 to transmit and receive the R2 forward / backward signal. Then, if the R2 signal is completed and the R2 signaling is not completed, the flow proceeds to step 105 to release R2 and terminate the operation. However, when the R2 signal is completed, the process proceeds to step 108 and the R2 time and the R2 signal are formatted and output as shown in Table 6 below.

Where Tx is displayed at origin and Rx is displayed at incoming.

time is the time displayed by I-O (hour: minute: second), same as R2 end time.

trk_port is the trunk port occupied by R2

R2_dur is the total time from R2 seizure-R2 Release (normal: 4-7sec, abnormal: other than)

Forward signal (FWD):

07 → Digit means '7' (where 0 is Forward GroupⅠ),

0A → Digit '0' means DMF,

C1 → Calling Category 1 is subscriber without priority (C is Forward Group II)

BWD (Backward Signal):

A1 → Next Digit (N + 1) Request (A is Backward Group A Signal)

B6 → Line Free, Charge meaning (B is Backward Group A Signal)

These messages are then displayed on the PC's monitor through the I / O port of the keyphone system.

As described above, the present invention monitors the R2 signal by setting the R2 signal tracking function using the key phone system, so that the transmission / reception signal system is processed into two digits to distinguish the forward / reverse signal from the calling category and the like. R2 signaling messages can be identified, and R2 signaling messages can be tracked by selecting only entire ports and fail ports.
