Integer32
The current over-subscription-factor for this ATM interface. Used for VBR and UBR VC connection admission control to allow the either VBR or UBR service category connections to collectively use more bandwidth than is available in order to make use of the statistical multiplexing of the connections. The PCR of each individual VC is limited to the interface's line rate. However when multiple VCs are configured, the sum of their PCR values can go up to (OverSubscriptionFactor * (line-rate) / 53*8). A value of 1 indicates no oversubscription allowed. A value of 5 indicates 5 times oversubscription allowed. Note that CBR connections cannot be oversubscribed. Also, if CES is in use on the interface, all AAL5 connections have their PCR limited to the amount which the line rate can support above the commitment for CES, and the oversubscription applies only to that bandwidth above the CES commitment.
