Section Abstracts

This Standard is applicable to the interconnection of data terminal equipment (DTE) and data circuit-terminating equipment (DCE) employing serial binary data interchange with control information exchanged on separate control circuits. It defines:

Section 2 Normative References

Section 3 Signal Characteristics

Section 4 Functional Description of Interchange Circuits

In addition, the Standard includes:

Section 5 Recommendations and Explanatory Notes

Application

This Standard applies where equipment on one side of the DTE/DCE interface is intended for connection directly to equipment on the other side without additional technical considerations. Applications where cable termination, signal waveshaping, interconnection cable distance, and mechanical configurations of the interface must be tailored to meet specific user needs are not precluded but are beyond the scope of this Standard.

Serialization

This Standard applies to data communication systems where the data is bit serialized. No restrictions are placed on the sequence of bits.

Synchronous/Nonsynchronous Communication

This Standard applies to both synchronous and nonsynchronous serial binary data communications systems.

Classes of Service

This Standard applies to switched, nonswitched, dedicated, leased or private line service. Consideration is given to both point-to-point and multipoint operation
