Allows the selection of the default timeslot background traffic. Not
suppoted on the IQS-8140. Choices are AIS and All zeros. The
default setting is AIS.

where the background traffic is also inserted for the unused
timeslots in a test case data path. The insertion is similar to the low

traffic format inserted uses the same rate as the one defined in the
test case data path.
