Description: The B channel number for this active entry. BRI interfaces have B channels in the range 1..2, PRI interfaces have B channels in the range 1..31, excluding a channel which is the D channel. A value of 0 for this entry means that either a B channel is not currently allocated for this call, or that more than one B channel is allocated. In the second case, the management client will have to walk the B channel allocation table looking for channels with the same active call index as this call's.

What is ccActiveCallBchannelIndex?

Reports which B channel (bearer channel) is allocated to an active ISDN call, with BRI interfaces using channels 1-2 and PRI interfaces using channels 1-31 (excluding the D channel). A value of 0 indicates no B channel has been assigned yet.
