1 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 CCITT¹) 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.

This Recommendation | International Standard provides the specification of management information within an Open System related to those operations of the OSI Physical Layer specified by the specifications in this Recommendation | International Standard. Specifics on how Physical Layer management is accomplished is beyond the scope of this Recommendation | International Standard. Physical Layer management is defined by specifying: - the managed object class definition of Physical Layer Managed Objects following guidelines put forth by the Structure of Management Information (see ITU-T Recs. X.720 | ISO/IEC 10165-1 to X.723 | ISO/IEC 10165-5; - the relationship of the Managed Objects and attributes to both the operation of the layer and to other objects and attributes of the layer; and - the action type operations on the attributes of Physical Layer Managed Objects that are available to OSI Systems Management.
