| Description | This object specifies the index of CAS variant that
is used by this DS0 group. The value of this object
is the same as the value of ccasVariantIndex in
ccasIfExtVariantTable.
This object is applicable only when the DS0 group is
in a DS1 line whose signal mode is configured for CAS
signaling, which means the dsx1SignalMode of the DS1
line is set to 'robbedBit(2)' for T1, or 'bitOriented(3)'
for E1.
When the DS1 line is configured for CAS signaling,
all the DS0 channels (ccasGrpCfgDs0Channels) in the
DS1 line must be in one and only one DS0 group.
It is a mandatory object when DS1 is configured for CAS.
If the DS1 is not configured for CAS and
ccasIfExtDs0GrpCasVariant is specified, the set operation
will be rejected, and it has a default value 0 when it
is not specified. |
