The following list defines the types of EPS, TPS, and RPS MPR-e radio switching operations that can be enabled using the tools>perform>mw>link command:
lockout—prevents the spare MPR-e radio from ever becoming the main radio, even when the main MPR-e radio fails; this operation overrides any forced, automatic, or manual operation
forced —forces the spare MPR-e radio to become the main MPR-e radio, even though it might not be in a fit state to assume the role. A forced switch operation overrides any automatic or manual switch operation that is in place.
automatic—allows an MPR-e radio to perform an automatic switchover if a fault condition exists. An automatic switch operation overrides any manual switch operation that is in place.
manual—attempts to switch the main/spare status of an MPR-e radio; however, if port failures, equipment failures, and reception failures do not allow the switchover, an automatic switch operation is triggered.
TDA switching operation is enabled via the MCT.
Refer to the 7705 SAR OAM and Diagnostics Guide, ‟Tools Command Reference”, ‟Tools Perform Commands”, for more information.
Revertive switching can also be configured for RPS and EPS/TPS (when revertive switching is configured for EPS, it is also applied to TPS; revertive switching for TPS cannot be configured separately). Revertive switching occurs when the MPR-e radio operation switches from the spare radio back to the main radio after a fault condition is cleared.
