GENERAL This Standard is applicable to the interconnection of data terminating equipment (DTE) and data circuit-terminating equipment (DCE) employing serial binary data interchange where a minimal number of control and information circuits are required. It defines: Section 1 - Scope Section 2- Interface Mechanical Characteristics Section 3 - Functional Description of the Interchange Circuits The electrical characteristics applicable to this interface can be found in AMERICAN NATIONAL STANDARD ANSI/EIA/TIA-562. CONNECTION When used in conjunction with the above mentioned electrical characteristics standard, this Standard applies where equipment on one side of the DTE/DCE interface is intended for connection directly to the other side without additional technical considerations. BIT SEQUENCES This Standard applies to data communication systems where data is bit serialized by the DTE and the DCE and places no restrictions on the arrangement or the sequence of bits. DATA SIGNALING RATES This Standard is applicable for use at all data signaling rates supported by EIA/TIA-562. NON-SYNCHRONOUS COMMUNICATION This Standard applies to non-synchronous serial binary data communication systems. CLASSES OF SERVICE This Standard applies to switched, non-switched, dedicated, leased or private line service, either two-wire or four-wire. Consideration is given both to point-to-point and multipoint operation.
