物理层功能 定义 介质类型 连接器类型 信令类型 Ethernet 802.3 V.35 物理层 EIA/TIA-232 Purpose: This section describes the physical layer in more detail. Note: 802.3 is responsible for LANs based on the carrier sense multiple access collision detect (CSMA/CD) access methodology. Ethernet is an example of a CSMA/CD network. EIA/TIA-232 and V.35 are physical standards that support synchronous serial.
