CAN/CSA-ISO/IEC 2593-00

Scope
 
This International Standard specifies the 34-pole connector and the assignment of contact numbers at the interface between data terminal equipment (DTE) and data circuit-terminating equipment (DCE) where CCITT (International Telegraph and Telephone Consultative Committee) Recommendation V.35 or Recommendation X.21bis together with Recommendation V.10 and V.11 are applicable.
 
NOTE 1 An interoperation between interfaces designed according to electrical characteristics specified in CCITT Recommendation V.35 and those specified in CCITT Recommendation V.11 is, at least to a limited degree, possible. This can be achieved, for example, by using a passive adaptor which joins the interface connectors in accordance with ISO 2593 and ISO 4902 or ISO 4903, respectively.
 
This International Standard specifies the dimensions of the connector housing and gives recommendations for the type of locking device (jack-screw system) and connector shielding.
