Abstract: PURPOSE: A PSTN(Public Switched Telephone Network) interface apparatus for narrow band service in an optical subscriber transmitter is provided to miniaturize an ONU(Optical Network Unit) in the side of the narrow band service, thereby capable of using a limited bandwidth effectively. CONSTITUTION: A DS1E line interface unit is dependent on an OLT(Optical Line Termination), is interfaced with a PSTN exchange through a DS1E interface structure and with an ATM switch through a B-ISDN interface device, and converts the DS1E signal transmitted from the PSTN exchange digitally and then changes into E1 frame and vice versa. A TSI unit allocates a time slot constructing E1 signal transmitted from the DS1E interface unit according to a command of a V5 processor to a provisioned subscriber's channel and vice versa. An ATM Inter-Working unit performs a function for reconstructing E1 data transmitted from the TSI unit as an ATM signal in order to transmit it to an upper ATM layer and vice versa. An S/UNI unit performs a function for transmitting the ATM signal to the B-ISDN interface unit and vice versa. The V5 processor performs a call processing function, a control function of time slot position reconstruction, an N-ISDN D-channel information processing function and a signaling processing function. A V5 processor interface unit performs a V5 message transmission function, an N-ISDN D-channel information transmission function and CAS(Channel Associated Signaling) function.

Abstract: PURPOSE: A random backoff apparatus for an augmented content reception and a method thereof are provided to enable multiple viewers to efficiently use a bi-directional service by preventing multiple reception terminals from being connected to a program-related website or augmented content at the same time. CONSTITUTION: A reception terminal (510) receives meta data from a server (520). In case a first random backoff is included in the meta data, the receiving unit (511) of the reception terminal indicates a reception request of augmented content by using the first random backoff. The control unit (512) of the reception terminal requests the reception of the augmented content to the server after implementing the first random backoff. In case the first random backoff is not included in the meta data, the control unit generates the first random backoff by using a probability distribution of predetermined random sampling numbers (502) and parameters of random sampling numbers (503).
