......................................................................
BSC_Test_ASCI: Add Talker detect with link fail test
The talker requests uplink. Instead of receiving link establishment from
the BTS, the BSC receives a link failure. The MSC expects to receive an
UPLINK RELEASE INDICATION, caused by radio link failure.
