Summary: This standard applies to have the bit-serial data transmission Telecontrol equipment and systems for the process of geographical WAN monitoring and control. This standard specifies the simplex and duplex link with the Statute, the work of packet transmission window size is 1 asynchronous data transfer. Note: the subsequent description, sometimes called the bit position. This standard specifies the link layer and physical layer provides application services to remote basic requirements. Data integrity to meet the requirements specified circumstances, special provisions of the variable frame length of the data frame or fixed frame length encoding, formation, and synchronization. Block code specified for bit-serial transmission frame in a binary symmetric channel transmission. The binary symmetric transmission channel with no memory bit encoding methods. This means that each bit of a signal transmitted in this specification and the bit independent of the signal prior to transmission. Note: In addition to using non-memory bit coding methods, is considering other data transmission services (such as a digital pulse width modulation DPDM, HDLC, etc.) and a window size greater than 1 full-duplex link protocol.
