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. It defines:

Section 2 NORMATIVE REFERENCES

Section 3 SIGNAL CHARACTERISTICS

Section 4 INTERFACE MECHANICAL CHARACTERISTICS

Section 5 FUNCTIONAL DESCRIPTION OF INTERCHANGE CIRCUITS

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.

Signaling rates

This Standard is applicable for use at data signaling rates up to a nominal limit of 128 kbit/s. Equipment complying with this Standard, however, need not operate over this entire data signaling rate range. Equipment may be designed to operate over a narrower range as appropriate for the specific application.

Synchronouslnonsynchronous communication

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