Number of timeslots per block reserved for data. The value of this object cannot be set outside of the range 0..36, inclusive. It should be chosen such that the following conditions hold: if dslLinkNumberOfBRA is zero dslLinkDataRate <= dslLinkLineRate if dslLinkNumberOfBRA is not zero dslLinkDataRate <= dslLinkLineRate - 2*dslLinkNumberOfBRA - 1 If the value violates this condition, the DSL link raises a 'configuration' alarm. The value of this object gives the guaranteed capacity available for data. If dslLinkDynamicSlotAllocation is true(1), the effective data rate may be higher.
