Generic BIND (GBIND) AMRUs

Access method RUs (AMRUs) are internal requests that might appear in the PIU trace and are a function of physical unit services (PUNS), configuration services, or session services.

Figure 1 through Figure 4 show the flow of these requests and responses between the SSCP and logical and physical units when a virtual route (VR) or explicit route (ER) selected for a session is not yet active.
