Specifies the action to take for one of the following DSP mismatch conditions:
- Mismatch in DSP card installation across any/all slot locations: Cards must match by slot location. For any mismatched slots, DSP capacity is not used when Preserve Redundancy is configured (and card dried up if calls were already in place when the mismatch occurred), or card is left unprotected when Preserve Capacity is configured.
- Mismatch in DSP card type within a slot location: Card installations must match by type – DSP25 (higher capacity) or DSP20 (lower capacity). Same rules as above apply.
The options are:
- Preserve Redundancy (default)
:
The active instance automatically triggers a graceful dry-up in an attempt to align DSP hardware capabilities. Once the dry-up completes, the active uses protected, matching DSP capacity to preserve redundancy.
Note: During the dry-up period, active calls using the higher capacity DSPs are not protected in the event that a switchover occurs before the dry up completes.
- Preserve Capacity: The active continues to use the extra DSP capacity, as needed, assuming appropriate session licenses are in place; partial redundancy is in effect.
Note: If a switchover occurs, calls using the higher capacity DSPs on the active instance are not protected during switchover (that is, partial redundancy).
