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 ITU-T

Recommendation V.36 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 ITU-T Recommendation V.36 and those

specified in ITU-T 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/IEC 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.
