【国外标准】 IEEE Standard for Medical Device Communications - Transport Profile - Connection Mode

The specifications and guidelines set forth in this standard are intended to define a local area network (LAN) for the interconnection of computers and medical devices. This standard defines the functions, features, and protocols of the intra-room communications subnet of a bedside communications network known as the Medical Information Bus (MIB). This communications subnet is the functional equivalent for the MIB of the Transport, Network, Data Link, and Physical layers of the Organization for… read more International Standards (ISO) Reference Model for Open Systems Interconnection (OSI). This standard defines the services and protocols for the MIB Transport, Network, and Data Link layers. The Physical Layer, specified in IEEE Std 1073.4.1-1994 Uses EIA-485 for data transfer.Provides DC power distribution for device communications hardware.Provides a pair of special function signals for the purposes of providing device connection indications, interrupt requests, time synchronization, and frame delimiting.Specifies a unique MIB connector and cable. The MIB Data Link layer offers services for data line connection, data transfer, and disconnection using high-level data link control (HDLC) procedures. The Transport and Network layers are inactive [i.e., there are no functions for packet assembly and disassembly (PAD) or end-to-end acknowledgments or any other services usually associated with Transport and Network layers].
