The present invention relates to an OW (Order Wire) control device used for optical communication and SDH (Synchronous Digital Hierarchy) communication network, and a control method thereof, and in particular for providing a smooth service in a multi-relay section and a transmission network of a ring structure A pulsating line control apparatus and method are provided.

1 is a block diagram of a conventional mash block.

The conventional mashing block is a signal input from the east (EAST) or the west (WEST) side is converted into a tone signal through a codec, then combined in an audio mixer (AUDIO MIXER) and transmitted to the DTMF (Dual Tone Multiple Frequency) section, where the tone The signal is converted into a signal that can be recognized by the central processing unit (CPU). The central processing unit (CPU) recognizes the number of the input signal and drives the light emitting diode (LED) in case of the local station number, and the tone generating unit (TONE). When the generator generates a tone so that the tone generator generates a tone, the bell rings through the speaker. The operator recognizes the signal and talks to the east or west side, which sent the signal through the TEL DRV. Such a structure can be connected to 2-wire or 4-wire or external public telecommunication network (PSTN).

As described above, the conventional short-circuit block of the optical communication and the microwave communication enables the simultaneous local communication in the entire transmission area.

Therefore, the conventional haptic line block as described above can be used only in a linear network or a communication network of a linear structure, or in a relay network or a ring-shaped communication network, which can transmit a relay section of a predetermined scale or less in a repeater section and a multiplexing section. Increased line noise and infinite looping of the batter line signal require additional batter filter and amplifier, mechanically cut one-way line, and integrate all signals into the AUDIO MIXER. Because all the unnecessary content is connected, there is a problem that there is no security at all in the important content.

In order to solve the above problems, the present invention can determine whether a specific signal is input to a received signal in a control signal detector, and accordingly, insert a control signal to the east side and the west side or reuse the other short-circuit line by transmitting the received signal. It is an object of the present invention to provide an apparatus and a method for controlling a short-circuit signal, which does not require a mechanical cutoff of a communication network even in a ring-shaped network.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

2 is a block diagram of a rhythm control device according to the present invention, 3 is a signal generator, 4 is a signal detector, 5 is a determination unit, 6 is a received signal, 7 is a conventional summing block, 8 is a multiplexer, 9 represents busy signal control units, respectively.

The present invention adds a signal promised in advance to the input signal of the pruning line by using transmission and reception to the east (EAST) side and the west (WEST) side in the optical communication and allocating bytes for the pitting line. These signals used the properties of the Pulse Code Modulation (PCM) codec. That is, the A-law PCM data format, + zero level, -zero level, + full scale, and-full scale (- full scale). Double the zero level value into the idle signal (IDLE code: no short signal) and the group call signal (Busy method commonly used in the existing short circuit) and busy code (Busy code). (Busy signal) is adopted among them. In the present invention, for example, the group call signal is 11110000, the idle signal is 01010101, and the busy signal is 11010101.

Therefore, the signal from the east (EAST) or west (WEST) side through the signal detector (CODE DETECTOR) 4 is determined by the DECISION LOGIC (5) and processed.

Looking at the specific configuration of the present invention. In the present invention, since the operation for outputting to the east side and the west side is symmetrical, the conceptual diagram is configured in duplicate, but the actual hardware configuration is composed of one hardware. However, the multiplexer 8, which will be described later, is doubled as a multiplexer included in the conventional mashing block 7.

When a signal comes in from the east and west sides through the conventional mashing line block 7, the present invention first defines it as a received data (Normal Data) 6. Thereafter, it is input to the A3 terminal of the multiplexer 8 to transmit it to the west side 1 and the east side 2, and to the signal detector 4 for analysis of the received signal.

The signal detector 4 analyzes the received signal 6 and distinguishes whether it is a Group Call, Busy, or Idle state. E, input by signal.

The busy signal control unit 9 receives the busy signal D from the signal detector 4 during the process and informs the determination unit 5 in which direction (Busy) a signal is input in which direction (east or west). The busy signal is transmitted as a visible audible signal to the conventional grounding block (7).

The determination unit 5 extracts the hook on / off state and the self identifier state from the conventional summing line block 7 as A and B, and groups the signal from the signal detector 4. Conventional pruning block (7) whether or not the signal of the signal generator (3) is inserted into the west side (1) or the east side (2) by receiving the call, busy, and idle signals as C, D, and E; It is judged whether or not to insert the received signal 6 of, and as a result, the state S0, S1, S2, S3 is transmitted to the multiplexer 8 according to the output signal of the busy signal controller 9. The detailed process will be described later in FIG.

The signal generator 3 generates idle, busy, and group call signals A0, A1, and A2, respectively, and multiplexes the western side (1) and the east side (2). Enter in (8).

The multiplexer 8 receives idle, busy, and group call signals from the signal generator 3 as A0, A1, and A2, and receives the received signal as A3 from the conventional short-circuit block 7. According to the outputs S0, S1, S2, S3 of the determination unit 5, one of A0, A1, A2, A3 is finally selected and transmitted in each direction (1, 2). There may be a plurality of such multiplexers depending on the direction of output.

3 is a flowchart according to the present invention.

When a signal is received (31), it is determined whether it is a group call (32). If it is a group call, it is judged whether it is currently in a local call (33). Until (35), pick up the handset (35) and insert the group call signal at the next stage (36). If the local station is busy, it is immediately connected with the group call signal line, and the group call signal is inserted 37 at the next stage.

If the received signal is not a group call, it is determined whether it is a local station call (38). If it is a local station call, first it is checked from which side it is input (39). It occurs until the operator receives the audible indication 40 (41), when the receiver picks up the receiver (41) and inserts an idle signal to the west (42). If the signal is from the west, it occurs until the operator receives (44) a visible audible indication (43) about the incoming call, and inserts an idle signal to the east when talking to the west by picking up the receiver (44). (45).

The received signal is neither a group call nor a local identifier call, or both the east and the west are idle signals, the station is busy or the station is only used as a relay station.

That is, it is determined whether the received signal is a group call, a local station call, or the east and west sides are idle signals (46). If both signals are idle signals, an idle signal is inserted to both sides (47), and either of them is an idle signal. If not, it visually indicates that the call is busy (48), and if both are not idle signals, the signal is relayed without processing the signal (49).

According to the present invention as described above, after determining whether a specific signal is input to the received signal in the control signal detector, the control signal can be inserted into the east side and the west side, or the received signal can be reused by transmitting the received signal, and a ring-shaped communication network can be used. Even when the network is not cut mechanically, there is no phenomenon such as infinite repetition of the signal, so it can be used for the operation of other short-circuit lines in a complex network.
