Error Mitigation (VSELP): Dual Level

Level 1: Extrapolates and replaces 30 msec voice

frames that exceed the error correction
algorithm tolerance

Level 2: Progressive muting of 30 msec voice frames

that are too severely damaged for Level 1
replacement

Error Mitigation Project 25-CAI (IMBE): Dual Level

Level 1: Extrapolates and replaces 20 msec voice

frames that exceed the error correction
algorithm tolerance

Level 2: Progressive muting of 20 msec voice frames

that are too severely damaged for Level 1
replacement
