Abstract: PURPOSE: An SS7(Signaling System No.7) connection system for connecting a PSTN and an ATM(Asynchronous Transfer Mode) network is provided to efficiently use system resources by efficiently transferring only an SS7 channel among PSTN TDM(Time Division Multiplexing) channels to an SS7 signaling block. CONSTITUTION: An SS7 connection system for connecting a PSTN and an ATM network is composed of a TDM bus(302), an AAL1(ATM Application Layer 5) SAR(Segmentation And Reassembly sublayer)(304), an AAL5 SAR(306), an SS7 signaling block(308), a time switch(310), and an ATM control block(312). The SS7 connection system transfers only an SS7 channel among TDM links to the SS7 signaling block(308) using the time switch(310), and other user data to the AAL1 SAR(304) or an AAL2 block. In other words, the SS7 connection system extracts all inputted TDM data by time slots using the time switch(310), and transfers only the time slot selected as the SS7 channel to the SS7 signaling block(308).

Abstract: PURPOSE: A device for controlling a non-real time traffic in an ATM(Asynchronous Transfer Mode) device is provided to monitor states of a switch queue to control a switch rate, and to perform an EPD(Early Packet Discard) when a reference value of a UBR(Unspecified Bit Rate) queue exceeds. CONSTITUTION: A receiving subscriber interface(311) stores cells received from a subscriber card and a trunk, and outputs the cells by a FIFO(First-In-First-Out) method. A switch(312) routs the cells according to header information, and outputs the cells to a transmitting subscriber interface. The transmitting subscriber interface stores the cells outputted from the switch(312), and outputs the cells by the FIFO method. An output queue monitor(315) monitors a threshold value of a transmitting FIFO of the transmitting subscriber interface. If a speed difference is over a setup threshold value, the output queue monitor(315) notifies the receiving subscriber interface(311) of that the speed difference is over the setup threshold value, and reduces a transmission data capacity by a receiver(311). If the threshold value of the transmitting FIFO is below the setup threshold value, the output queue monitor(315) transmits a signal for releasing an alarm state to the receiving subscriber interface(311).

Abstract: PURPOSE: A device for monitoring a queue state in an asynchronous transfer mode(ATM) switch is provided to perceive the queue state of the ATM switch in a subscriber board of an ATM exchange system, so as to control an available bit rate(ABR) traffic. CONSTITUTION: A memory stores an inputting time of a resource management(RM) cell and an outputting time of the transmitted RM cell. A forward resource management(FRM) processor detects an inputting time of a former RM cell stored in a memory when the RM cell is inputted from a source, and calculates a time difference between the inputting time of the RM cell and the inputting time of the former RM cell to insert the time difference into a FRM cell transmitted to a switch. A backward resource management(BRM) processor detects an outputting time of the former RM cell stored in the memory when the FRM cell is outputted from the switch, and calculates a time difference between the outputting time of the FRM cell and the outputting time of the former RM cell, then calculates the difference between an inputting time difference and an outputting time difference to insert the difference into a BRM cell transmitted to the switch. A speed calculator confirms a difference value between the inputting time difference and the outputting time difference of the BRM cell transmitted from the switch, and calculates an explicit cell rate(ER) value and a scheduler rate(SR) value. A speed controller decides a switch queue state by the difference value, and controls a cell transmitting speed according to the ER value and the SR value.
