3.1 GENERAL

3.1.1 INTERFACE DESCRIPTION

The Node 2 to USL on−orbit configuration is shown in Figure 3.1.1−1, Node 2 to USL On−Orbit Configuration. Dimensions and material characteristics at the Common Berthing Mechanism (CBM) interface are in accordance with SSP 41004, CBM to Pressurized Elements ICD. The interfaces between Node 2 and the USL have the following functions: (a) provide a shirt−sleeve environment passageway for crew members and equipment and (b) provide connectivity for utility functions. The Node 2 to USL functions are shown in Figure 3.1.1−2, Node 2 to USL Functional Interfaces.

3.1.1.1 NODE DESCRIPTION
