BS 4505-2:1990

This standard BS 4505-2:1990 Digital data transmission is classified in these ICS categories:

• 35.040.10 Coding of character sets
• 35.200 Interface and interconnection equipment

This International Standard specifies the character structure to be used for serial-by-bit start/stop and synchronous data transmission systems using the 7-bit coded character set which is the subject of ISO 646¹⁾, the 8-bit coded character set which is the subject of ISO 4873 and extensions to these coded character sets which are the subject of ISO 2022.

It also specifies the parity sense to be used with the 7-bit coded character set.

It applies to the information transfer through the interface standardized by CCITT and IEC/ISO between the data terminal equipment, DTE, and data circuit-terminating equipment, DCE, as defined in the relevant CCITT V and X series Recommendations.

Specifies character structure to be used for serial-by-bit start/stop and synchronous transmission using the UK 7-bit and 8-bit data codes.
