| Summary | This standard specifies the Ethernet frame (defined by the working group IEEE802. 3) over SDH protocol stack, which can be used for synchronous digital hierarchy (ITU-T G. 707 standard). ITU-T X. 85/Y. 1321 introduced LAPS protocol standard and norms continue to be used for the Ethernet adapter to provide LAPS. Describes a similar HOLC LAPS framing structure used to package IEEE 802. 3 Ethernet MAC frame, which provides a point to point full duplex operation. LAPS, Ethernet and SDH physical layer as well as the relationship between the rate adaptation layer shown in Figure l, in the coordination of sub- layer has the flow control function. This standard does not specify the specific LAPS to SDH mapping method for all Ethernet-based protocols (including IEEE 802. 3 Ethernet) and all the SDH standard without any alteration. |
