    • A next-generation network system employing TCM(Time Compression Multiplex) ISDN(Integrated Service Digital Network) technique and its control method are provided to stabilize system by canceling noise generated as data service lines are integrated. A synchronous clock generating unit(100) generates a TTR(Transmit Timing Reference) clock to be used to a TCM ISDN and an xDSL(x-Digital Subscriber Line) through a broadband clock provided through a ATM(Asynchronous Transfer Mode) network and supplies it. A TCM ISDN subscriber processing unit(200) temporarily stores TCM ISDN data received from a PSTN(Public Switched Telephone Network), aligns frames of TCM ISDN data, transmits the TCM ISDN data to a TCM ISDN subscriber after synchronizing the TCM ISDN data with the TTR reference clock. The TCM ISDN subscriber processing unit(200) synchronizes TCM ISDN data received from a TCM ISDM terminal(4) with the TTR reference clock inputted through the synchronous clock generating unit(100), temporarily stores it, and then transmits it to the PSTN.

    • A caller identification (ID) demodulating apparatus and method using multiple thresholds. An apparatus according to one embodiment comprises a zero crossing detector for generating pulses at points where the modulated caller ID information crosses zero and outputs each pulse as a zero crossing signal, a data extractor for computing a zero crossing interval between each output pulse of the zero crossing signal, and comparing the zero crossing interval with a plurality of thresholds to generate extracted data, and a clock generator for generating a data recovery clock signal for recovering the extracted data in response to the extracted data, wherein the data recovery clock signal is enabled at the middle point of the unit data length of the extracted data. The apparatus and method use multiple thresholds to extract data from caller ID modulated in a CPFSK format, thereby accurately extracting data at an interval where data "0" and "1" coexist. Furthermore, the clock signal for demodulating extracted data is generated about at the middle point of the unit data length of the extracted data, thereby demodulating data accurately.
