The output shows a summary of B-channel interfaces and the active ISDN calls on the interfaces. The first example shows the two B-channels on an ISDN BRI interface—bc-2/0/0:1 and bc-2/0/0:2. The second example indicates B-channels bc-2/0/0:1 through bc-2/0/0:23, the 23 B-channels on an ISDN PRI interface. Determine the following information:
