Abstract: The stuffing circuit minimizes an influence of a waiting timing jitter occurred from a demapping part in the case of mapping an asynchronous DS1 (2.048 Mbps) signal to the synchronous payload. The two step stuffing circuit comprises an 8 bit elastic buffer (2) for synchronizing the received data (2.048 Mbps) by a system clock (2.0488 MHz); stuffing bit S2 controllers (17,18) for compensating the difference between the above two clocks; a frequency adjuster (20) converting the system clock (2.0488 MHz) into a VC12 (virtual container) frame clock (2.240 MHz); a PLL circuit (19) for generating 2.0488 MHz clock of duty 50 %; stuffing bit S1 controllers (21,22); a 32 bit elastic buffer (1).

Abstract: First, a search is made as to whether the inputted command is a maintenance code or a file transmitting code. Then an inputted command is saved into a register, and a watch is made as to whether a transmitting key is inputted. If a transmitting key is inputted, the saved command code is transmitted to an electronic switching system, and then, the final message for a maintenance command is displayed and saved. If the inputted key is a file transmitting command, then a link with the switching system is formed to receive or transmit a file. If a transmitting key is inputted, the saved character data are transmitted to the switching system, and the character data which are transmitted from the switching system are displayed.

Abstract: The apparatus is for interfacing the different transmission type by depositing a modulator between the transmission lines. The modulator modulates the μ-type applied to PCM multiple system to A-type applied in Europe and vice-versa. The modulator inclludes a time signal generator (20) for generating timing signal by dividing a frame synchronous clock and clock pulse of the transmitted data, a control unit (30) for checking the transmitting data by receiving the data using a time switch (40) and a timing signal of the time signal generator (20), and stopping or executing the A/μ modulation according to the channel throug which the data is transmitted, and a modulator (10) for transmitting and receiving the serial data, executing the A/μ modulation of an audio PCM channel and transmitting the modulated audio PCM channel through the TDM bus.
