INFORMATION PROCESSING - START STOP TRANSMISSION SIGNAL QUALITY AT DTE & DCE INTERFACES
05-07-2001
12-01-2013
Describes signal quality requirements for serial data transmission at the interface between start stop transmission data terminal equipment and data circuit terminating equipment. Conforms to CCITT recommendations V 24 and X 24. The signal quality characteristics apply regardless of whether or not multiplexing equipment is included. They do not apply where there is intermediate equipment and no signal regeneration is provided between interconnected sections. Does not describe the signal quality of the DCE or the line associated with it. Neither does it describe any requirement for an acceptable bit error rate. Does not specify the speed characteristics. The nominal value of the modulation rate and the character interval are application dependent.
