ISO/IEC 2593:2000 pdf download-Information technology — Telecommunications and information exchange between systems — 34-pole DTE/DCE interface connector mateability dimensions and contact number assignments.
4 Connector Specifications A 34-pole connector shall be provided for the DTE/DCE interface. Figures 1 to 5 illustrate the 34-pole connector. Only those dimensions that are essential for mating are shown. Figure 1 illustrates the DTE connector which has 34 male contacts in a connector housing. Figure 2 illustrates the DCE connector which has 34 female contacts in a connector housing. The connector housing on the DTE connector is dimensioned to fit inside the connector housing on the DCE connector (see figures 1 and 2). Contact identification lettering is also specified in figures 1 and 2. The use of shields and mounting flanges is illustrated in figures 1 and 2 respectively. Since their shape and size is not essential for mating, the use of different shape and size from those illustrated does not affect conformance with this International Standard. Figure 3 illustrates the dimensions for the contact spacing. Figures 4 and 5 illustrate the dimensions for the male and female contacts respectively. Figures 8 and 9 illustrate the connector mountings. The connectors shall be equipped with a jack- screw system (see figures 6 and 7 and tables 2 and 3). On the DTE connector, the female jack- screw (nut) shall be positioned adjacent to the male contact lettered A and the male jack-screw shall be positioned adjacent to the male contact lettered MM. Both jack-screws of the DTE connector shall be rotateable. On the DCE connector, the female jack-screw (nut) shall be positioned adjacent to the female contact lettered MM and the male jack-screw shall be positioned adjacent to the female contact lettered A. Both jack-screws of the DCE connector shall be fixed to prevent rotation. Connectors shall use either the 6-32 UNC thread in accordance with the present specification of IEC 60807-6 or, if required by national regulations or mutual user agreement, M 3 as specified in ISO 261 . When procuring equipment internationally which will use this 34-pole connector, the user shall specify the thread type in accordance with national requirements. NOTES 2 The nominal contact diameter of 1,6 mm is referred to as size 1 6 in IEC 60807-7.
