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.
