TIA/EIA 602 : A2000(R2014)

Applicable to the interconnection of data terminal equipment (DTE) and data circuit terminating equipment (DCE) employing serial binary data operation via the 100-series interchange circuits. Identifies the protocol elements, procedures, and behaviors that were found to be held in common among a large portion of DCE manufacturers. It is intended, as much as possible, to preserve compatibility between DCEs and DTEs. Most DCEs implement a number of extensions and behavioral differences beyond the descriptions of this Standard; such extensions and differences are explicitly permitted by this standard.
