Channel: All traffic in the current version of SatLink is transferred on the logical channel 0,
which is the default logical channel from the VSAT to the satellite Hub.
CRA: Allocated CRA capacity (DVB-RCS Continuous Rate Assignment capacity). The DVB-
RCS Hub assigns CRA capacity to the VSAT at logon. Changes in the CRA level
assigned to the VSAT during its log-on session are sent to the VSAT. The amount of
CRA to be assigned to the VSAT is a network operator/service provider decision.
Allocated: Allocated refers to the total aggregated amount of capacity (CRA + RBDC +
VBDC/AVBDC + FCA) that the NCC has granted to the VSAT as a grand total for all
QoS classes.
CRClass: CRClass 0 represents BW demand for the BE PHB. CRClass 1, 2, and 3 represents BW
demand for the VoIP PHB group, the ViC PHB group, and the VoIP PHB group,
respectively.
MaxRBDC: Maximum RBDC is the upper limit of Rate-Based Dynamic Capacity that a VSAT can
request. The maxRBDC is set from the DVB-RCS Hub and is a network/service
provider decision. The VSAT is pre-configured with a default value of maxRBDC for
the Best Effort QoS class. This default value will be overwritten by the operator-defined
value at logon.
MaxVBDC: MaximumVBDC is the upper limit of not yet granted VBDC/AVBDC requested that a
VSAT will have outstanding at any time. The maxVBDC is set from the DVB-RCS
Hub and is a network/service provider decision. The default value of this parameter is 0.
This default value will be overwritten by the operator-defined value at logon time.
