OID for Active B Channels

[kendr2]

I want to log how many B Channels are in-use on a PRI, throughout the day.

I'm poking through AVAYA-AURA-CM-MIB ... but I don't see an 'Active Channels' counter for ISDN circuits.

I have found the PRI of interest to me:
AVAYA-AURA-CM-MIB::avCmListTrunkRangeGrpNumber.1 = INTEGER: 1
AVAYA-AURA-CM-MIB::avCmListTrunkRangeGrpName.1 = STRING: Qwest
AVAYA-AURA-CM-MIB::avCmListTrunkRangeServiceType.1 = STRING: public-ntwrk
AVAYA-AURA-CM-MIB::avCmListTrunkRangeCarMedium.1 = STRING: PRI/BRI

And I have found moderately interesting variables, like
AVAYA-AURA-CM-MIB::avCmMeasTrkGrpSumYestPercentAtb.1 = INTEGER: 0
which tells me that yesterday, 0% of the time were all the channels within this Trunk Group in-use.

But that isn't quite what I want -- I want to chart usage on the PRI, gathering a data point, say, every 5 minutes.

Any pointers? I've searched for 'Active Channels' and "in use", but those keys haven't lead me to cheese.
