| ¿µ¹®³»¿ë¿ä¾à | This standard specifies the common transmission convergence (ComTC) layer of higher speed passive optical network (HSP) systems, and operate at rates specified in related PMD recommendations. This standard supports both time division multiplexing (TDM), and time and wavelength division multiplexing (TWDM) modes of operation. As a general rule, TDM operation is considered a single wavelength channel pair case of TWDM operation. This standard uses line rate parameterization to generalize the TC functions to enable a line rate agnostic TC specification for all HSP systems. This standard specifies:
¡á A layered structure containing three sublayers ¡á Functionality of the ComTC service adaptation sublayer, including the use of 10-Gigabit passive optical network (XG-PON) encapsulation method (XGEM), XGEM frame delineation, and service data unit (SDU) fragmentation ¡á Functionality of the ComTC framing sublayer with the specification of the downstream frame and upstream burst formats ¡á Functionality of the ComTC physical interface (PHY) adaptation sublayer, including ¡á Synchronization, forward error correction, scrambling, and downstream interleaving ¡á PON embedded management functionality, including control of the upstream time-division multiple access and dynamic bandwidth assignment mechanisms ¡á The physical layer operation, administration, and management (PLOAM) messaging channel ¡á The optical network unit (ONU) activation cycle state machine, covering activation, and wavelength channel handover ¡á Timing aspects of PON point-to-multipoint operation and time-of-day communication ¡á Performance monitoring, supervision, and defects ¡á Security including cryptographic mechanisms for authentication, integrity verification, channel isolation, and data protection along with the associated key exchange protocols ¡á Signaling mechanisms and protocols to support ONU power management; ¡á Wavelength channel management ¡á System protection ¡á Alien device and rogue ONU behavior mitigation. |
