This read-write Integer32 (50-200) is the traffic scaling factor used to compute the factored bandwidth signaled in ATM for establishing a voice SVC, values below 100 act as a discount factor and above 100 as an excess factor, and it applies only to VBR SVC connections, not to AAL2 SVC calls using G.711 or clear channel codecs. An admin cares because this factor lets an operator adjust how much bandwidth is actually reserved relative to the codec's nominal rate, tuning network utilization versus headroom. For example, an operator wanting to conservatively over-provision bandwidth for VBR voice SVCs to protect quality would set this above 100 as an excess factor.
