frUniDlciSpCommittedBurstSize
Frame Relay Uni Dlci Sp Committed Burst Size
This attribute specifies the committed burst size (Bc) in bits. bc is the amount of data that a network agrees to transfer under normal conditions over a measurement interval (t). Data marked DE=1 is not accounted for in Bc. This attribute is ignored when rateEnforcement is off. If rateEnforcement is on and this attribute is 0, cir must also be 0.
