28、ector A 26-pole connector shall be provided for the DTE/DCE interface. Figures 1 to 4 illustrate the connectors. Only those dimensions that are essential for mating are shown. The DIE-DCE interface point is defined at the point between the cable connector associated with the cable attached to the DT

29、E and the equipment connector associated with the DCE. Figure 1 illustrates the cable connector which has 26 male contacts in a connector housing. Figure 2 illus- trates the equipment connector which has 26 female contacts in a connector housing. The connector housing on the equipment connector is d

30、imensioned to fit inside the connector housing of the cable con- nector (see figures 3 and 4). Figures 3 and 4 give contact numbering and illustrate the dimensions and latching mechanism for the cable and equipment connectors respectively. 5 Assignment of contacts The assignment of contact numbers i
