    The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings.
    Referring to Fig. 1, the configuration of the present invention will be described. When a signal message is received, a time for driving the NO.7 message signal processing program and a signal processing program within the own station to switch a signal input to the own station or another station using a time difference is used. A signal is provided to the switch 110, the DLC 120 to provide a call channel to the time switch 110 and the subscriber relay line, and to perform a time slot switching function, aggregation, and a matching function with a line processor (not shown). DLC status management unit 130 for connecting signals between the local station and other stations by transmitting a message such as setup message, digit information and device number, call connection request, call termination request, etc. When the abnormal state occurrence signal is received from the state manager 130, the alarm processor 140 to notify that an abnormal state has occurred and input of input data In charge of the output of the output data, it is configured to include an input output unit 150 that mates with the heat exchanger.
    Referring to the block diagram of the switch 100 suitable for DLC description with reference to the accompanying Figure 1,
    When the signal message or the packet data is received, the time switch 110 drives a packet processing program, a NO.7 message signal processing program, and a signal processing program within the own station to switch the signal inputted to the own station or another station using a time difference, Transmits and receives switched signals through a space switch (not shown) or trunk (not shown).
    The DLC 120 is a hardware element that provides a call channel to the time switch 110 and the subscriber relay line, and is composed of a multiplexer, a demultiplexer, and a memory, and has a 1,024 time slot switching function and an aggregation and line processor (not shown). Perform the matching function.
    The DLC 120 is divided into a time switch function and a connection function. The time switching function receives 2,048 Kbps data from an input subhighway, and demultiplexes 8,192 Kbps parallel data. One DLC handles up to four input / output subhighways.
    When a signal is input, the DLC state management unit 130 transmits a message such as a setup message from the subscriber, information messages such as digit information and a device number, a call connection request, a call termination request, and the like to connect signals between stations. The subscribers are connected through the power station, and the call is terminated under the control of the main processor (not shown).
    The input / output unit 150 is connected to the alarm processing unit 140, performs a command received by receiving an operator's command, informs the operator of alarm information of the switch 100, and periodically informs the operator of the operating state of the switch 100. In addition, by displaying the operation state of the other switch 100 to the subscriber at the request of the operator so that the operator can easily know the information of the switch 100.
    When the abnormal state occurrence signal is received from the DLC state management unit 130, the alarm processing unit 140 generates an alarm signal to inform the operator that an abnormal state has occurred, thereby causing the operator to take an appropriate action. Take it.
    With reference to the accompanying Figure 2 will be described in detail with respect to the channel designation step in the DLC (120),
    The line processor periodically checks the DLC 120 status by periodically scanning the DLC 120 managed by the line processor (step 202).
    At this time, the margin of the DLC 120 allocated to the time switch 110 is periodically checked according to the scanning period and reported to the DLC state manager 130 (step 204).
    The DLC state manager 130 receives the margin state of the DLC 120 from the line processor and stores it in the digital state management table in the DLC state manager 130 (step 206).
    For example, the operator arbitrarily allocates the reserve rate to the DLC 120 subscriber with MMC commands such as DLC-CRTE; MPno, LPno, E1_no, PFXno, DLCno.
    When the subscriber reserve rate is allocated, the line processor senses and informs the DLC state manager 130 of the exchange 100 of the subscriber reserve rate information. The table in the DLC state manager 130 is updated with new data (step 208).
    The table in the DLC 120 checks and stores this state change.
    The operator checks the table in the DLC 120 with a Man Machine Communication (MMC) command to determine whether a reserve rate abnormality has occurred (step 210).
    If it is determined in step 210 that the reserve ratio does not occur in the DLC 120, the collection ratio and the reserve ratio information are transmitted to the input / output unit 150 so that the reserve ratio information can be checked in the input / output unit 150 (step 212). ).
    If it is determined in step 210 that the reserve rate abnormality occurs in the DLC 120, when the abnormal state occurrence information is detected by the line processor and notified to the DLC state management unit 130 of the exchange 100, the reserve rate is transmitted to the alarm processor 140. Notifying that the abnormality has occurred, the alarm processing unit 140 detects the alarm information and informs the operator that the abnormality has occurred in the reserve rate through the input / output unit (step 214).
    The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.
    As described above, in the present invention, the existing allocation method has flexibility in relay line allocation by reassigning 128 of the 256 DLC channels to the subscriber, and remaining 128 to the subscriber not using the 128 relay channels. By providing liquidity, if the same ratio of 4: 1 as the conventional method, it is possible to accommodate more subscribers.
