Platform-Specific Information
B-Channel Activation
When a call comes in, a B channel is activated. If the amount of traffic on the B channel exceeds a
threshold, the other B channel is activated. If the amount of traffic falls below the threshold, one of the
B channels is deactivated. The B channel that is initially activated when the call comes in is not
necessarily B1, nor is the B channel that is deactivated when the traffic level lessens necessarily B2.
