This read-write yes/no setting enables fallback to 8 Kbps with triple buffering, the most latency-tolerant of the three 8 Kbps buffering options alongside ifvceRate8kx1 and ifvceRate8kx2. Triple buffering absorbs the most jitter of the three but adds the most delay, so it suits the noisiest links where even double buffering isn't enough. For example, on a particularly jitter-prone wireless backhaul, an administrator might enable this object over the single- or double-buffered 8 Kbps options to keep calls intelligible despite the added latency.
