Abstract: A PCS(Physical Coding Sublayer) apparatus and the Ethernet layer architecture of a T-PON(Tunable-Wavelength Passive Optical Network System) having a wavelength variable type optical source are provided to support a wavelength initialization and alignment of an ONT(Optical Network Terminal) based on a PLC-ECL(Planar Lightwave Circuit-External Cavity Laser) by independently determining an ONT optical signal. A PCS apparatus of a T-PON having a wavelength variable type optical source includes a wavelength monitoring unit(615), and an automatic recognition unit(614), a transmission unit(611), and a receiving unit(612). The wavelength monitoring unit(615) extracts wavelength information from a digital frame signal transmitted from an ONT, and monitors whether the wavelength information is ONT optical source assignment wavelength information or not. If the wavelength information is not matched with the optical source assignment information of the ONT, the automatic recognition unit(614) adds wavelength control information to the digital frame signal and transmits the added information to the ONT. If the wavelength information is matched with the optical source assignment information of the ONT, the transmission unit(611) encodes and transmits the data transmitted from the ONT to a MAC layer. The receiving unit(612) decodes and receives data of the MAC layer.

Abstract: The present invention relates to a WDM/SCM-PON and a media access control method for asymmetric packet communication in the same. In the WDM/SCM-PON, each SCM channel is classified and used as a link by adopting an SCM technique of subdividing a wavelength band of up/downstream data links between an OLT and ONTs into frequency bands, and the ONTs are formed so that a certain SCM channel is independently distributed not fixedly assigned. Accordingly, an inventory problem, which can be generated in WDM/SCM, is prevented before happens, asymmetric dynamic band allocation is performed, and asymmetric service of up/downstream transmission is supported. As a result, a band required for next generation service is dynamically provided, optical interference effect is minimized, and Ethernet compatibility is provided so that Ethernet service suitable for providing IP service can be accommodated.

Abstract: PURPOSE: A method for processing proxy signaling in an asynchronous transmission mode switching system is provided to realize a function similar to an SVC(Switched Virtual Connection) function without using a terminal having an ATM signaling function. CONSTITUTION: A UNPCF(User Network Interface Protocol Control Function) block of an ACC(ATM Call Controller) transmits a setup message to a UNCCF(User Network Interface Call Control Function)(S601). The UNCCF confirms whether the current service is a proxy signaling service vicarious execution(S602). If so, the setup message is analyzed to confirm the abnormality or contents of information elements(S603). If normal, connection identifier information is analyzed from the setup message to assign the corresponding connection identifier(S604-S605). A VCI(Virtual Channel Identifier) is assigned in the corresponding VPI(Virtual Path Identifier) value(S608). A proxy logic port corresponding to relation is searched for with a group number and an extracted VPCI(Virtual Path Connection Identifier)(S607). A bandwidth is confirmed in the proxy ports having the consistent group number(S609). A VPCI value and a VPI value are extracted from the proxy port satisfying the bandwidth for assigning a VCI of the VPI value(S610). The corresponding VPCI and the assigned VCI are put in the connection identifier to be transmitted to a PSA(Proxy Signaling Agency)(S611).
