Common use of Frame Bearing Capability Clause in Contracts

Frame Bearing Capability. A bundle may be provisioned with a minimum acceptable level of operational bandwidth for the bundle. Operational bandwidth is available from a bundle link when BL_ACTIVATE indication is received. The total operational bandwidth available is calculated by adding the operational bandwidth available from each bundle link. Four classes of bandwidth requirements are shown in Table 2. One class is selected to determine the criteria that trigger activation or deactivation of the emulated physical interface. When the bundle's operational bandwidth meets the criteria for a selected class, the bundle must send a PH_ACTIVATE to the data link layer. When the bundle's operational bandwidth fails to meet the criteria for a selected class, the bundle must send a PH_DEACTIVATE to the data link layer. Class Description Criteria for PH_ACTIVATE/PH_DEACTIVATE Class A (Default) Single link PH_ACTIVATE: PH_DEACTIVATE: One or more bundle links indicate BL_ACTIVATE. All bundle links indicate BL_DEACTIVATE. Class B All links PH_ACTIVATE: PH_DEACTIVATE: All bundle links indicate BL_ACTIVATE. Any bundle link indicates BL_DEACTIVATE. Class C Threshold A minimum threshold is provisioned through network management procedures. The threshold represents the minimum number of bundle links that must indicate BL_ACTIVATE. PH_ACTIVATE: Sufficient bundle links indicate BL_ACTIVATE. PH_DEACTIVATE: Insufficient bundle link indicates BL_DEACTIVATE. Class D Custom PH_ACTIVATE: PH_DEACTIVATE: Implementation specific. Implementation specific. Table 2 Class of Bandwidth Requirements
