BS ISO 4903:1989 is a British Standard and International Organization for Standardization (ISO) standard titled "Information technology - Data communication - 15-pole DTE/DCE interface connector and contact number assignments." This standard specifies the physical interface for data communication between data terminal equipment (DTE) and data circuit-terminating equipment (DCE). The interface uses a 15-pole connector, and this standard defines the pin assignments and functions for each contact in the connector. DTE refers to devices such as computers, terminals, or printers, while DCE refers to devices like modems or multiplexers. The interface between these devices is essential for establishing communication links, and standardization ensures compatibility and interoperability across different equipment from various manufacturers. BS ISO 4903:1989 provides a standardized approach to the physical connection and pin assignments, which helps in the design, manufacturing, and deployment of data communication equipment. By adhering to this standard, organizations can ensure that their equipment can connect and communicate effectively with other compliant devices in data communication networks.
